Best 6-Burner Gas Grills for Large Cookouts
If you're feeding 20 people at a neighborhood cookout, a 3-burner grill isn't going to cut it. Six burners give you the cooking real estate to run different heat zones at once, so burgers, chicken thighs, and corn can all land on the table at roughly the same time.
The difference between a good 6-burner grill and a great one usually comes down to three things: total cooking surface, BTU efficiency, and how evenly the burners hold heat across the entire grate. A grill pushing 60,000 BTUs over 900 square inches is doing real work. That same output over 600 square inches is just burning things.
These five grills cover a wide range of budgets, from under $530 to nearly $2,700. All of them were chosen for actual backyard performance, not just spec sheet numbers.
Best Premium 6-Burner Grill: Weber Summit E-670
The Weber Summit E-670 is the grill you buy once and never think about replacing. Six stainless steel burners, a dedicated sear station, a rear infrared rotisserie burner, and a smoker box built right into the grill body. The 769 square inches of primary cooking space handles 30 burgers at once without crowding, which matters when your July 4th guest list keeps expanding year after year.
What separates the E-670 from cheaper 6-burner options is the build quality throughout. The stainless lid is thick, the temperature gauge is accurate, and the burners distribute heat evenly from left to right. On a large patio where the grill is a centerpiece, this one looks as good as it cooks. It is a real investment at around $2,649, but the 10-year warranty on burners and cooking grates means you are not shopping for a replacement in three years.

Shop on Amazon →Best for Serious Searing: Napoleon Prestige Pro 665 RSIB
If high-heat searing matters to you as much as volume cooking, the Napoleon Prestige Pro 665 RSIB earns its spot in any serious backyard. It comes with four main burners plus a dedicated infrared side burner and a rear infrared rotisserie burner. That infrared side burner hits temperatures that standard burners cannot touch, which means you get a proper crust on a thick ribeye without pulling out a separate cast iron pan.
The 665 series has 900 square inches of total cooking space including the warming rack. It is a large footprint, so plan for a dedicated spot on a bigger patio with at least 12 feet of clearance. The build is heavy-gauge stainless throughout, and the JETFIRE ignition system holds up well after years of outdoor exposure. At around $2,299, it is competitive with the Weber Summit and offers a legitimate infrared advantage for anyone who grills steaks or thick chops on a regular basis.

Shop on Amazon →Best Mid-Range 6-Burner: Char-Broil Commercial TRU-Infrared
The Char-Broil Commercial TRU-Infrared 6-Burner sits in a sweet spot around $849 that most backyard cooks are actually shopping in. The TRU-Infrared cooking system distributes heat evenly across the cooking surface, which means fewer flare-ups and fewer cold spots when you are cooking 40 chicken thighs for a graduation party. Total cooking area lands around 650 square inches, which is enough for a serious group meal without wasting patio space.
The Commercial series has a noticeably sturdier build than Char-Broil entry-level lines. The lid feels solid, the side shelf locks in place, and the enclosed cabinet gives you actual storage for a spare propane tank and your grilling accessories. If you are hosting 15 to 20 people a few times a summer, this grill hits a practical balance of quality and cost that the premium brands cannot match at half the price.

Shop on Amazon →Best Budget 6-Burner Grill: Dyna-Glo DGB730SNB-D
The Dyna-Glo DGB730SNB-D is the most cooking surface you can buy for under $530. Six burners putting out 60,000 BTU total, 730 square inches of primary cooking area, and a 12,000 BTU side burner included. That is a lot of grill for the price. The open cart design is not as polished as a cabinet-style grill, but the cooking performance is legitimately solid for the cost.
The porcelain-enameled cast iron grates hold heat well and clean up easily. The burners run consistently across all six positions, which is not always the case in this price range. If you are setting up for a large family reunion on a budget, or buying a grill for a vacation rental property, the DGB730 is hard to beat. It is not glamorous, but it does the job without complaint.

Shop on Amazon →Best Value for Regular Entertaining: Nexgrill 720-0896E
The Nexgrill 720-0896E fills the gap between budget and mid-range better than almost anything else at this price. Six main burners plus a dedicated sear burner, around 660 square inches of primary cooking space, and a stainless steel finish that does not look cheap sitting on your patio. It consistently ranks among the top sellers for 6-burner grills on Amazon, and the review volume tells you it is not just hype.
For weekend cookouts with groups of 12 to 18 people, this grill handles the volume without much fuss. The side tables fold down when you need to tuck it in tighter on a smaller patio. The sear burner is a genuine bonus at this price point, letting you finish steaks or get a crust on thick pork chops without a separate setup. If the DGB730 feels too utilitarian and the Char-Broil TRU-Infrared is a stretch for your budget, the Nexgrill is the answer.

Shop on Amazon →Quick Tips for Cooking on a 6-Burner Gas Grill
- Use heat zones, not full blast. Run two or three burners on high and keep the others on medium or low. This gives you a hot zone for searing and a cooler side for holding food without overcooking it.
- Preheat for a full 10 to 15 minutes. Six burners take longer to heat the cooking surface evenly. Rushing the preheat leads to uneven grill marks and food that sticks.
- Do not ignore the side burner. A side burner is genuinely useful for heating sauces, warming buns, or keeping a pot of corn going while the main grill is working at capacity.
- Brush grates before every session. With a large grill cooking for a big group, residue from the last cookout will smoke and transfer off-flavors. A quick brush when the grill is hot takes 30 seconds.
- Check your propane before guests arrive. A 20-pound tank running six burners on medium lasts roughly 8 to 10 hours. Have a backup tank on hand if you are cooking all day.
- Keep the lid closed as much as possible. Every time you open the lid on a large grill you lose significant heat. Flip less often and trust the grill to do its job.
Frequently Asked Questions
How many people can a 6-burner gas grill feed at once?
A 6-burner grill with 700 or more square inches of cooking space can handle 25 to 30 burgers at a time, which means feeding 30 to 40 people over the course of a cookout is realistic. The actual number depends on what you are cooking and how organized your timing is.
What is a good BTU rating for a 6-burner gas grill?
For a 6-burner grill, look for 50,000 to 70,000 BTU across the main burners. More important than raw BTU is BTU per square inch, which should be at least 80 per square inch of primary cooking area. Grills advertising 100,000 BTU total are usually counting side burners and infrared burners in that figure.
Is a 6-burner gas grill worth it for home use?
It depends on how often you entertain. If you are cooking for 10 or more people multiple times a summer, a 6-burner grill pays for itself in convenience and stress reduction. If you mostly cook for 4 to 6 people, a 4-burner grill gives you plenty of space without the larger footprint.
How much patio space do I need for a 6-burner gas grill?
Most 6-burner grills are 60 to 70 inches wide with side tables extended. You need at least 3 feet of clearance on all sides for safe operation, so budget a total footprint of roughly 10 by 5 feet. Check your local fire safety guidelines for any additional clearance requirements.
What is a sear burner and do I need one on a gas grill?
A sear burner is a high-intensity infrared element separate from the main burners, designed to reach 900 to 1,000 degrees Fahrenheit for a proper crust on steaks and chops. It is not essential, but it is genuinely useful if you cook thick cuts regularly. Both the Napoleon Prestige Pro 665 RSIB and the Nexgrill 720-0896E include one.
