Weber still makes our favorite overall grill, but others in the test cohort impressed us in our 2026 round.
David WatskyAfter another round of grilling, temperature and usability tests, these are the best gas grills of 2026, rigorously evaluated and recommended by CNET.
What’s the best gas grill overall?
Weber’s powerful and fairly affordable Spirit E-325 is our top pick for 2026.
David Watsky/CNETAfter putting more than a dozen grills through weeks of rigorous testing, one clear winner emerged: the Weber Spirit E-310. It earns this spot, and a CNET Editor’s Choice, not only because of Weber’s sterling reputation for making quality grills that hold, but because it outperformed all the other grills in its price category, making it a clear pick for the best overall value in gas grills.
Weber grills are well-designed, easy to use, and tend to last, which is why the brand now holds three of the seven spots on our list of the best grills. But there are other contenders to consider, including a large 7-burner behemoth for feeding an army and an uber budget-friendly pick for under $250.
Recent testing and updates
May 2026
The Weber Genesis EX-325W was tested and added to the list of the best smart grill upgrade. The Char-Broil Performance Series 4-Burner was tested and added to the list as best budget grill for 2026. The Weber Spirit E-325 was tested and added as the best overall gas grill. The Monument Denali 605 was retested and maintained its position as the best large grill. Five additional grills were also tested, but did not make the list.
Best gas grills of 2026
Pros
- Solid and sturdy
- Sear zones hit temps well above 700 degrees
- Quick ignition system worked without fail
- Heats quickly and with even heat dispersion
- Webers tend to hold up better than other grills, making this a solid value purchase
Cons
- No extras included
- The 3-burner size may be small for some households
What we liked:
The Weber Spirit’s popularity is well-documented, but its reputation alone isn’t enough to convince us. In speed, temperature, and consistency tests, the Weber E-325 performed as well as or better than any grill on the list, reaching well over 700 degrees in under 15 minutes. It also held its temperature within a few degrees during a 30-minute consistency test and regained temperature after the lid was opened and reclosed with impressive speed.
Its three-burner setup and 450 total square inches of cooking space — including the top rack — are enough to handle most backyard grilling sessions with ease. That said, it fits roughly nine average-sized burgers at a time, so expect to cook in batches when you’re feeding a larger crowd.
The Weber Spirit cookbox is made from cast aluminum, engineered to resist rust and corrosion better than the stainless steel used by many of its competitors. The snap ignition system was notably more reliable than its competitors, too, consistently lighting all three burners. Based on our long-term experience with Weber grills, the ignitions hold up over the years.
Who is it for:
The Spirit earns its place as our top pick for most backyard cooks. It delivers consistent, even heat, and the sear zone gets hot enough to put a proper sear or char on steaks, burgers, salmon, and vegetables. Factor in Weber’s reputation for long-term durability, and this grill becomes an exceptional value — offering more for your money than most competitors in the same price range.
Who should avoid it:
The Spirit E-325 keeps things straightforward and is not loaded with extra features, so if you’re after built-in thermometers, side burners or other add-ons, you may want to explore other options on our list.
Its mid-size cooking surface is also worth keeping in mind; if you’re regularly grilling for a large group, stepping up to the bigger 4-burner model will save you the hassle of cooking in multiple batches.
If you don’t need all that power, the Weber E-310, which is essentially the same grill but without the sear zones, can be had for about $50 less.
Pros
- Exceptionally fast heating and even temperature control
- Sear zone gets well over 700 degrees F
- Built-in temperature probe helps keep tabs on food as it cooks
- Sturdy build and simple controls
Cons
- On the expensive side
- No extras like a griddle top or side burner
What we liked:
Traditional grillers may scoff at the idea of a smart model, but after testing Weber’s feature-rich Genesis EX-325W Smart Gas Grill, we certainly see the appeal. The Genesis EX-325W heated faster than any other grill we tested and kept an even heat across all four quadrants. It also has one of the most powerful sear zones of any grill we tested, reaching well over 700 degrees to impart a healthy crust on chicken and burgers.
In true Weber fashion, the build quality and finishes feel premium. The caster wheels rolled smoothly across the deck, and the ignition worked without fail in the dozens of times we triggered it.
Who is it for:
Smart tech enthusiasts, fans of low-and-slow cooking, and easily distracted chefs will appreciate the Weber’s smart features. The app and the connected internal probe worked well to keep tabs on the food as it cooked. This function is especially useful for making foods with long cooking times, such as bone-in chicken, briskets, roasts and racks of ribs. Through the app, you’ll get an estimated completion time and allow users to upload recipes with cooking times.
The digital readout is mostly accurate, too. The only hiccup we’ve had with a Weber Smart Grill was while cooking pork ribs low and slow. According to the grill’s LED screen, heat levels during the cook were set to a 10-degree range around 225 F. Our own thermocouples, though, pegged the grill temperature at about 45 degrees cooler. As a result, our ribs took longer than expected: 6 hours and 30 minutes.
Who should avoid it:
At $1,000, this is the priciest grill on our list, so it’s not for budget buyers or casual grillers. Despite its impressive functionality and built-in features, the Genesis Smart Grill has fewer add-ons than some of the grills we tested. There’s no griddle — although one can be purchased separately — and no side-table burner as with the Char-Broil FlavorMax 4.
Pros
- About as inexpensive as a gas grills get
- Heats quickly and maintains heat evenly
- Sleek all-black look
- Light and easy to wheel around the deck
- Assembly is straightforward
Cons
- No sear zones and doesn’t get as hot as other grills we tested
- Flimsier build than a Weber
- Side tables can’t be folded down
- Handle gets hot during cooking
- Charbroils don’t last as long as pricier grills
Why we liked it:
Considering how expensive everything has become, paying under $300 for a full-size gas grill is a steal. Charbroil’s Performance Series four-burner will run you between $249 and $300 and performed well in our testing, making it a clear pick for the best cheap grill in 2026. The build, while not as sturdy as Weber’s and the premium grills we tested, was solid, and assembly was no more involved than others on the list.
The Charbroil heated slightly more unevenly than some of the competition, but not enough to dramatically impact typical grilling. The cooking chamber reached 600 degrees F in about 15 minutes. That’s significantly cooler than the more powerful grills we tested, which have sear zones that top 700 degrees. Still, 600 degrees F is plenty of firepower to do most of your weekend grilling.
The Performance Series comes in two formats, one with a gas tank cupboard and one with open shelves. We could make a case for both since cupboards can collect grease and debris, and are sometimes difficult to clean. On the plus side, they protect your gas tank from the elements and keep an unsightly metal can out of sight.
Who is it for:
This is a solid grill for about as cheap as you’ll find one. The Performance Series doesn’t have many features, but the burners lit dutifully upon ignition and maintained their flame during several cooking tests. We loved the sleek black look, though it’s available with a stainless-steel hood if you prefer.
Who should avoid it:
Those seeking a premium grill to last a decade or more may want to look elsewhere. In general, Charbroil grills don’t hold up as well over time as Webers and other high-end grills, since the brand uses thinner steel and lighter components that are more prone to rust and corrosion. Webers, for instance, have cast-aluminum cookboxes, while this Charbroil model uses simple painted steel. Because of that, you’ll want to take special care of this model, clean it regularly and keep it protected from the weather with a cover whenever not in use.
One other minor nuisance is that neither side table folds down to fit in a smaller space, although the right-side table can be easily removed by loosening a few screws.
Pros
- A built-in smoker gives ribs, chicken and brisket an authentic barbecue flavor
- Convection fan disperses heat evenly throughout the chamber
- Griddle attachment let us cook fish and veggies on one side without losing them through the grates
- Plenty of space to grill on the 545 square inches of cooking surface
Cons
- Expensive and most attachments are extra
- Must be plugged in to operate
Why we liked:
Ninja’s first foray into full-size grilling, the FlexFlame, is unlike anything else we’ve tested. This large propane-powered grill comes with a built-in smoker box that activates at the push of a button, infusing food with your choice of applewood or hickory flavor.
It also supports a wide range of attachments — most of which are sold separately — that can transform it into a flat-top griddle or a pizza oven. On the performance side, the FlexFlame impressed us with pinpoint temperature control, a searing max heat of 600°F, and remarkably quick heat recovery after opening the lid to flip burgers or check on chicken.
We loved making seared steaks over the grates on one side and using the half-griddle attachment to cook flaky fish and veggies on the other. The FlexFlame offers more versatility than most grills and is easy to operate.
The grill’s exceptional heat control, thanks to a convection fan and carefully calibrated dials, makes it a joy to roast chicken or slow-cook a brisket. The built-in smoker box lets wannabe pitmasters impart authentic barbecue flavor.
Read our full review of the Ninja FlexFlame here.
Who is it for:
This is a big, feature-heavy grill that makes a joy to entertain large groups with. The main grill surface offers 424 square inches of cooking capacity (enough for about 15 burgers) and a stop rack supplements with another 121 square inches. You can cook using multiple modes and methods at once, including flat-top griddling, smoking and a dedicated pizza stone for slinging pies.
Who should avoid it:
The FlexFlame has a bunch of features that contribute to the higher cost. If you don’t think you’ll use the smoker function or griddle attachment, it might not be worth the expense. This grill also requires electricity to run, which can be cumbersome depending on your outdoor configuration.
Pros
- Efficient design means plenty of grilling capacity
- Heated evenly in our tests
- Sturdily built
- One powerful 8,500-Btu burner
- Ignition was easy
- Easy to move around
- Available in a range of colors
Cons
- Heavier than other small grills we tested
- On the expensive side for a portable grill
What we liked:
We’ve been testing portable grills for five years, and a Weber Q series model has held the top spot on our best list each and every year — and for good reason. The compact Q1200 lights without fuss and heats evenly from a single 8,500 BTU burner. Its flip-up side tables make cooking and prep surprisingly comfortable for a grill this size. At 30 pounds, it’s heavier than some portable competitors, but that weight is a feature, not a flaw — it’s the natural result of a cast aluminum body and Weber’s signature porcelain-coated cast-iron grates, both built to go the distance.
Who is it for:
With 189 square inches of cooking space — enough for roughly eight 4-ounce burgers — you could make this your main grill but we’d suggest buying the cart and an adapter so you can hook it up to a larger propane tank since the Coleman camping canisters would run out quickly. We found it plenty easy to lug around via the built-in handles, making it a perfect grill to take camping, in your RV or to a tailgate.
Who should avoid it:
If you’re seeking a truly portable grill to lug on hikes or long meandering camping trips, there are lighter, more portable grills. Our picks can be found on this list of the best portable grills for 2026.
Pros
- Largest cooking surface of any grill we tested
- Side burner helps when making a full meal
- Big power thanks to 84,000 total Btu
- Good value for a big grill
Cons
- Assembly takes awhile
- Large grills can be a chore to clean
- Uses a ton of propane
What we liked:
The Denali makes a strong first impression with its generous cooking space — there’s plenty of room to feed a full party without the juggling act. A standout detail is the built-in slots for hanging drumsticks, which keep them elevated and cooking evenly on all sides. Everything we tested came out tender, and the temperature probes took the guesswork out of knowing when each cut was done.
Chicken thighs were perfectly cooked through, and burger patties were evenly browned on all sides. The side burner proved its worth too, letting us simmer a pot of barbecue beans alongside the meat without a single trip back inside — the kind of convenience that makes a real difference when you’re hosting.
Who is it for:
While a giant six-burner grill may not be for everyone, the Monument Denali strikes the perfect balance of modern design, value, and quality build. Like any smart modern grill, the Denali has temperature probes to cook food accurately and connects to your phone via an app. You can set the app to alert you when your food reaches the correct temperature or when a set time limit is reached.
Who should avoid it:
Our only complaint with the Denali 605 is the time it took to build. It comes disassembled for easy shipping, but putting it together was tedious, with a lot of guesswork when the instructions weren’t clear. Once it was built, it worked great, but it was a pain to get it together.
The CNET editors have been cooking and serving up grill data for a few years now. In addition to the gas barbecue models above, here are the other gas grills we’ve tested. This list doesn’t include the many models we’ve tested over the years that are no longer available for purchase.
- Monument Mesa II 415BZ : It was a true photo finish between this formidable and affordable grill and the Charbroil Performance series for best budget pick. We loved the Mesa’s solid build and appreciated the side burner. Ultimately, the $399 tag kept it out of the mix when compared with the $250 Charbroil grill.
- Charbroil Pro Series 4-Burner Grill: This feature-heavy 4-burner grill impressed us in all tests. It comes with a griddle attachment and a side burner for sauteeing veggies or cooking a pot of beans. Ultimately, the slightly flimsy build and high price tag ($779) kept it out of the top.
- Charbroil Signature Series four-burner: We tested this well-built, practical model in a previous round of evaluation. It was middle of the road in our testing and the new model is available for around $550. It comes with plenty of cooking space, a side burner and cabinet doors. If you’re a fan of Charbroil’s grills, this model is a safe bet.
- Napoleon Rogue three-burner: Despite its cool looks and sturdy construction, this Napoleon model was underwhelming in our tests. At $749, it’s pricey and Weber models for a similar or lower price offer better results.
- Dyna-glo five-burner: This reasonably priced five-burner has plenty of power, with 63,000 BTU, plus a sixth “turbo” burner that adds 12,000 BTU. We like its porcelain cast-iron grate cooking surface for searing. Still, we found the cooking to be uneven.
- Charbroil Commercial three-burner:This grill with smart features was a previous pick on our list but it’s been usurped as best under $600 model by the Weber Spirit E-310.
- KitchenAid 720-0891C (Update: Out of Stock): KitchenAid’s style and color options are impressive, but this $299 two-burner gas grill performed underwhelmingly in all three tests. If you’re looking for a two-burner grill, the Weber Spirit II E-210 is a better choice. It’s a propane grill but can also be converted to natural gas. This model is also pretty tough to find in stock since it was recently discontinued.
- Magma Firebox Single-Burner: This is another grill I liked but it’s not portable or affordable. The burner alone weighs 26 pounds and originally cost $200 (although it’s currently on a steep clearance), but you’ll need to add the grill top accessory, which costs $350. This model was engineered with boaters in mind, so if you’re setting sail, you might give the pricey Magma a closer look
- Giantex tabletop propane grill: I had no major issues with this grill. It worked fine, got hot and cooked evenly. Compared to the Weber Q, I simply prefer the design of those small gas grills. The Weber Q is more solid and has those handy built-in shelves while the NomadiQ is simply the most portable gas grill I’ve ever seen. This is a fine grill and worthy of the $300 list price.
- Charbroil Deluxe Tabletop Grill: While the above Char-Broil might work as a no-nonsense budget grill, this model is way too poorly designed and crafted to waste $70. It is one of the worst for value in the small grill category and a definite one to avoid.
- Charbroil Portable Gas Grill: This grill is cheap, and the product matches the price tag. It was rickety once assembled and didn’t feel like it would last more than a season. For $50, what more could you hope for? If you need something to get you through a camping weekend or two, this should do the trick.

We tested the unique features of each gas grill and ran three distinct cooking tests on all of them.
David Watsky/CNETTo determine the best gas grill and get a feel for how these grills perform in a variety of cooking scenarios, we perform heat control and cooking tests. Based on different meats, methods and heat settings, these tests show us how efficiently and evenly a grill does (or doesn’t) cook.
Max temperature test
We strapped probes to each grill to see how quickly they heated and the max temp reached.
David Watsky/CNETTo test the grill’s max temp, we placed a thermocouple probe 2 inches above the grates in all four quadrants. The temperature probes are connected to a data logger and laptop with software that records the internal temperature of each chicken breast every 2 seconds. With the hood closed, we ignited the grill and set the burners to high. We recorded the hottest temperature each grill reached as well as how long it took to reach max temp.
Temperature consistency test
We also tested how evenly each one distributes heat and how consistent it is in maintaining a temperature over 30 minutes.
David Watsky/CNETTo test how consistently each grill holds heat, we ran a similar test with probes in all four quadrants. We set the grills to medium heat and ran them for 30 minutes. We then analyzed the temperature over the 30 minutes of cooking, noting any big swings or inconsistencies among the quadrants or zones.
The data told us a story, but not the whole story.
Katie Collins/CNETChicken to test searing ability and even cooking
We cooked chicken to test each grill’s ability to produce char and how evenly it heats.
David Watsky/CNETTo test a grill’s ability to sear and cook evenly across all zones, we cooked chicken. After preheating the grill, we placed 3-ounce boneless, skinless chicken thighs on each og the grill’s four quadrants and cooked them with the lid closed for 7 minutes. After seven minutes, we flipped the chicken and cooked for an additional ive minutes or until each piece reaches a food-safe 165 degrees Fahrenheit. Grilled chicken pieces should be cooked evenly, with a slightly charred exterior and meat that’s cooked through but not dry.
Ribs to test slow cooking
We also made ribs. Lots and lots of ribs.
David Watsky/CNETOur rib test is an anecdotal round, so there isn’t a connected thermometer set or software capturing specific data. We preheated each grill on high for 10 minutes before turning it down to low, indirect heat. Depending on the grill size, that means turning one or two burners off completely.
We remove the outer membrane from a rack of pork back ribs and season it with an all-purpose rub we use for ribs and chicken. Then, the ribs are placed on the grates for at least three hours with the lid closed the entire time.
Rib testing takes three hours on low, indirect heat.
Chris Monroe/CNETRib enthusiasts may not agree with this relatively short and smoke-free cooking method, but it allows us to see just how well a regular propane gas grill can cook low and slow. If time allows, we will continue cooking until the ribs are completely done and make note of the total cook time.
How much should you spend on a gas grill?
A few of the pricier smart grills had built-in probe systems for precise temperature monitoring.
James Bricknell/CNETWhile knowing what you want in a gas grill is important, knowing what you can spend is the first step when buying a grill. This is because you may want a six-burner grill, with a hot plate on the side, and a searing deck, but if you’ve only got $350 to spend, you’re going to have to make some compromises. Now, there are still plenty of good gas grills in this price range, but when the spread between entry level and high-end is thousands of dollars, it’s best to determine what you can afford first.
A side burner is nice to have but not something we deem essential.
David Watsky/CNETThe reliable full-size grills we tested start at around $400 for a two-burner Weber. You can go cheaper with a budget grill brand like Charbroil or lesser-known producer, but don’t expect that unit to last as long or function as efficiently.
Charbroil’s Performance Series can be had for under $300.
David Watsky/CNETLarger 5- and 6-burner grills typically run between $700 and $1,000. At that price, you’ll get more total cooking area and often more raw power for searing steaks and extras like a side burner, smart connectivity. In the case of the Ninja FlexFlame, a built-in smoker and convection fan for outdoor roasting and baking.
Gas grill fuel source: Propane vs. natural gas
Milk crates make great holders for propane tanks to keep them upright and easier to carry for transportation.
Chris Wedel/CNETThe most common gas grill you’ll find when shopping around is propane. These grills are more portable, as you can simply hook them up to a 15- to 20-pound bottle and roll them wherever you need them. Just make sure you properly dispose of or trade in your propane bottle when it’s empty.
The other type of gas grill would be one that uses natural gas. For some this isn’t an option at all because this utility isn’t available at your home, or you prefer to have a more mobile grill. If you have natural gas as a fuel option, the main benefit would be that you won’t have to worry about running out of fuel and you’ll save money in the long run since you won’t have to pay for propane bottles or refills.
We take our gas grills seriously.
David Watsky/CNETBenefits of natural gas grills
- Low-maintenance, always-ready grill for regular backyard use
- Long-term savings on fuel
- A cleaner, greener way to cook
Benefits of propane gas grills
- Easier to move your grill around
- Fewer installation costs and logistics
- More grill options to choose from
How much raw heat do you need?
For the best crust on steaks and burgers, a grill with sear burners is preferred.
Tyler Lizenby/CNETThe heat rating for grills is done in British Thermal Units, and while the higher the BTUs generally means more heat, a lower number doesn’t make the grill bad. There are many factors that go into determining the best BTUs needed for a particular grill. A grill with 700 square inches of cooking space would likely be underserved by only 25,000 BTUs, but a smaller grill would be perfect at that rating. A good rule of thumb to ensure the BTU rating and grill size are optimal for your needs is to divide the total BTUs by the total cooking area. Aim for around 110 BTUs per square inch.
Size and capacity
The Denali from Monument sports a whopping 900 square inches of cooktop.
Monument GrillsBefore you buy, do a mental audit of how many people you’ll be cooking for regularly. If you tend to host large gatherings, you’ll appreciate the extrs grate real estate. If it’s only once in a while, the smaller grill will save money and space on the deck.
Small, portable gas grills start at around 150 square inches, enough for 5 to 7 burgers. Midsized grills offer 300 to 400 square inches of cooking space, enough for 10 to 12 burgers. The largest gas grills we tested had as many as 900 total square inches of cooking space.
Most gas grills run on propane, though some are designed for natural gas. Beyond fuel type, a number of factors distinguish one grill from another — cooking surface size, grate material, and BTU output all play a role in how a grill performs, and those differences show up in testing.
One pattern our data consistently reveals is how quickly a grill cooks on its own medium or high setting. This isn’t a comparison of identical temperatures across grills — it simply means we turned each knob to whatever that grill labeled “medium heat” and observed the results. It’s a more realistic measure of how the grill will actually behave in everyday use.
It really comes down to how you cook. If you’re regularly grilling for a crowd, you’ll want a larger primary cooking surface, a warming rack, and ideally a side burner to keep things running smoothly. But if most of your meals are for a smaller group, a more compact grill will serve you better — it’ll cost less, heat up faster, and generally be easier to manage. Buying more grill than you need rarely pays off.
Once you’ve picked out the best gas grill for you, you’ll want to look at grill covers and pick up grilling tools like a grill brush, a thermometer to check for food-safe temperatures and liners for the drip tray. There are loads of great cooking tools that can be used on all types of grills, it just comes down to what works best for you and your cooking style.
Generally, at the end of summer is the best time to buy a grill. Starting around Labor Day, you’ll start seeing grills go on sale to make room for fall and winter seasonal items. You can also find good sales during major holidays, especially summer ones like Memorial Day, Fourth of July and Father’s Day.
Ideally, your grill will have 80 to 100 BTUs per square inch of cooking surface. For example: a 400 sq. in. grill would have roughly 36,000 BTUs for effective performance.
