Our recommendations for Best 6-Burner Gas Grills:

Why Choose a 6-Burner Grill?

Manufacturers tend to use the same burners throughout their model lines, which reduces their costs and makes parts more available to the consumer. This means that grills from the same brand are often pretty similar to one another.

So if they’re all the same, what is the advantage of having more of them?

Here are some good reasons to get a gas grill with 6 burners:

Size: Most brands are only going to put 6 burners into bigger grills. So if you’re looking for a large rig to feed a lot of people, you’ll probably want to take a look at models like these. 

Heating Power: Having more burners means extra grilling power and more heat to the cooking surface. And that’s what you need to get that nice sear on your steaks and burgers!

Heat Zones: Having 6 burners offers more control and allows you to create several heat zones. This means you can sear steaks on one side while cooking chicken wings on the other side without burning them.

Indirect Cooking: If you’re looking to try your hand at special techniques like smoking, slow-cooking, and baking, a grill with 6 burners is a great option.

It’s tough to find a better value grill than the Megamaster, especially if you’re looking for a 6-burner model.

While it doesn’t have all the bells and whistles of other models on our list, what it does have is bullet-proof, old-school technology. The Megamaster has powerful burners, providing 54,000 BTUs of heat, and cast-iron cooking grates for excellent heat distribution and retention.

So what are you missing by saving so much money?

  • Porcelain-coated cast iron grates

What We Don’t

The Genesis II also features Weber’s GS4 high-performance grilling system, which includes an infinity ignition system, high-quality stainless steel burners with enameled Flavorizer bars, and a grease management system. All in all, this is a great value grill for all of the features you get.

Picking the Best 6 Burner Gas Grill

Size and Power

Probably the biggest factor in choosing a gas grill is how big you need it to be.

Are you cooking for a small family or a bunch of 20 hungry guys? What do you cook on the grill – just the meat or all of the sides too? 

Consider carefully just how much food you need to put on the grates to figure out what is the right size for you. More space isn’t always better. Set your budget, and you might be able to get a smaller, higher-quality grill that you will like cooking on more.

When looking at the BTUs (British Thermal Units) that a grill produces, remember to look beyond the biggest number. More significant factors in your cooking will be the quality of the grill and how well it distributes those BTUs to the cooking grate.

Thinking that a 6 burner might be too large?

You can also check out our guide with the best 3 burner gas grills and get a smaller unit instead.

Durability and Warranty

If your grill lives outside in a harsh environment, you’ll want to invest in one of high quality. Steel components can rust quickly, especially in the South or places with a lot of humidity and salt in the air. 

Stainless steel and aluminum components are best. All grills will benefit from a well-fitting cover when not in use, and keeping them clean and rust-free will add years to their lives. 

It’s a good idea to pay attention to the warranty as well. Also, read the fine print to make sure you understand which components are covered and which are not.

Special Features

The best 6 burner gas grills offer three features of special interest. Many of these things can be added with aftermarket parts, but it will never work as well as if it’s built right into the grill. 

A rotisserie system is an excellent item if you like to cook whole chickens, turkeys, or even gyros!

Many grills also have infrared burners mounted vertically on the back of the grill, specifically for rotisserie use.

A side burner is another feature that’s taken for granted sometimes. It’s great for whipping up sauces, pasta, or soups while you cook outside. 

If you like steak or chops, you might want to consider a grill with a high-powered searing burner. These burners distribute heat a little differently and often utilize infrared technology to get that initial sear just right.

I hope this guide helped you with picking the right 6-burner grill for your needs.

Have a great barbecue!
