Weber Genesis II SX-335 Smart 3-Burner Gas Grill

There are a lot of cool gadgets and gizmos out there for the home cook, but perhaps none quite as versatile as this Weber Genesis II SX-335 Smart 3-Burner Gas Grill. With Wi-Fi capabilities that allow it to be monitored remotely, along with a high-quality build and multi-purpose design, this gas grill is the total package. It’s easy to assemble, simple to clean and very sturdy. The main grilling space is 513 square inches with an additional 156 inches on a warming rack, which means you have plenty of room for two cooking zones whether grilling directly or indirectly. Its 39,000 BTU burners are powered by propane or natural gas (via the optional adapter hose).

Some real standout features include Step-by-Step grilling assistance and alarms for food readiness countdown timers so you can spend your time relaxing and enjoying the party instead of hovering over your grill. And if you need to step away from the grill or run an errand? No problem! You can easily monitor your food using your phone thanks to its Wi-Fi capability.

The one downside is its steep price tag, although when compared to other models on our list featuring similar technology like iGrill3/4 monitoring systems or side burners, it actually comes at an affordable price point.

Weber Spirit SX-315 Smart 3 Burner Grill

The Weber Spirit SX-315 gas grill is a 3 burners smart grill. This is an upgraded version of the S-315 model, with the same size cooking area but more features that make it easier to use.

The grill can be connected to WiFi and your smartphone so you can check on your food from anywhere in your home. It also has temperature monitoring and keeps a record of when you cooked what, so you can duplicate your success in the future. The grates are made of cast iron, which makes them heavy and durable, yet easy to clean even after years of use.

The three stainless steel burners offer 32,000 BTU power output and promise excellent performance. The main cooking surface is 424 square inches while the warming rack offers 105 square inches capacity. A convenient side table provides additional space and there are six tool hooks for easy access to utensils while barbecuing. The two wheels allow for easy maneuverability if you need to relocate your grill or store it somewhere else during winter months.

Coleman RoadTrip 285 Portable 3 Burner Gas Grill

If you love camping, grilling on picnics, or are a tailgating fan, the Coleman RoadTrip 285 is just what you need. You can easily pull this portable 3-burner barbecue along with you because of its clever design. It folds down into a compact unit with large wheels and a folding frame handle for easy pulling behind you to your favorite grilling spot, be it in your garden or out in nature.

This portable gas grill heats up quickly thanks to its 20,000 BTU heat output across a 285 square inch cooking surface. The three burners may be independently controlled to create two separate heat zones so that meat, veggies and other goodies can cook at different temperatures all at once. Using the Insta-Start push-button ignition makes sparking up a breeze! You can also switch out the grill top depending on your needs—the porcelain cast iron grates are strong enough for most foods but if you prefer cooking fish like trout or salmon there’s an optional fish grate accessory available as well.

While the pullout side tables are very convenient (and fold away neatly when not in use), you should exercise caution when placing anything heavy on them because they tend to break easily due to weak joints. If you plan on bringing this gas grill on a road trip, it’s advisable to secure the lid with a bungee cord or some other kind of knot to keep it shut so that nothing falls out of place during transit. Coleman has thoughtfully provided storage hooks for all sorts of extras like utensils, tongs and more as well as four drink holders for keeping everyone’s beverage cold while waiting for dinner—after all no one likes warm beer!

Coleman’s RoadTrip 285 portable barbecue is one of the finest on the market even if it isn’t quite suitable for regular home grilling because propane tanks aren’t meant to be stored indoors (unless they are empty) due to safety

Napoleon Rogue 425 3-Burner Gas Grill

If you’re looking for a 3 burner gas grill that is both powerful and aesthetically pleasing, the Napoleon Rogue 425 3 Burner Gas Grill is a fantastic choice. It offers a huge number of features at an affordable price, making it one of the best grills in its class.

With its sleek black porcelain enamel top, doors, control panel, and shelves, this grill can withstand even harsh environments while also adding some visual flair to your outdoor kitchen. Its high BTU output (42000) across 425 square inches of cooking space allows you to cook many different types of foods with ease while assisting in overall food consistency.

The reversible cast iron porcelain-enameled grates and Jetfire ignition mechanism make cooking simple and convenient, while dual-level stainless steel sear plates ensure your food maintains an ideal temperature without burning or sticking to the grate. The wave-shaped grate also prevents tiny pieces from falling through during cooking and ensures equal heat distribution across all foods.

Char-Broil Classic 360 3-Burner Liquid Propane Gas Grill

If you’re looking for a budget-friendly option, the Char-Broil Classic 360 is a great choice. Three stainless steel in-line burners and 30,000 BTUs of heat give this grill plenty of power to tackle three courses or large cuts of meat. A warming rack with a surface area of 170 square inches that may be removed helps you keep everything warm until it’s time to eat. The side burner is perfect for preparing items such as vegetables in the pot or frying eggs and sausages on the pan.

While this model doesn’t have all the bells and whistles that more expensive grills do, it will still get the job done at an affordable price point. Porcelain-enameled grate, lid, and firebox provide increased durability and ease of cleaning over other materials. The two metal shelves are excellent for storing utensils while you cook. Two six-inch wheels allow easy maneuvering across your backyard patio—even if it’s uneven—so you don’t have to worry about getting your shoes dirty!

Unfortunately, some reviewers have noted problems with uneven heating across the grill surface; however, issues like these can usually be fixed with a few adjustments to how you use your grill (and often don’t require calling customer service). Others also say that lighting system can sometimes be finicky: make sure to keep backup lighters or matches handy just in case! Overall though? For an unbeatable price tag under $150 USD…

Royal Gourmet 3-Burner Portable Tabletop Gas Grill Griddle

Are griddles the new grills? If you’re looking for a versatile way to cook, maybe they are. Royal Gourmet has created a tabletop version of this dish.

Griddles are an excellent all-around option for cooking a wide variety of foods, from steaks to smash burgers and stir-fries to morning pancakes, and they’re easy to take camping or tailgating.

Over a 316-square-inch cooking surface, three independent burners allow you to create distinct heat zones with a total of 25500 BTUs. In windy conditions, you might need to adjust each burner or move your food around more often to get an even heat distribution from this appliance.

The griddle top may be removed for simple cleaning, unlike your traditional gas barbecue with three burners. This model includes a slide-out drip tray that’s convenient but the drip hole is so small that if you’re not on level ground, grease can run down the side or out the back of the unit.

It’s not a terrible griddle for the money and it’s small and portable enough to take with you when you travel but if you’re looking for a more permanent installation maybe consider another product instead

Dyna-Glo DGP397SNP-D Premier 3 Burner Propane Gas Grill

The Dyna-Glo DGP397SNP-D Premier 3 Burner Propane Gas Grill is a great purchase for anyone looking for an inexpensive, high-quality three burner grill.

Cast iron grates promote even heating and produce beautiful sear marks, but they can rust if they are not properly maintained. This three burner gas grill’s integrated ignition system enables you to start cooking quickly, while the enclosed cart protects your propane tank from the elements.

Thanks to four caster wheels (two of which lock), this barbecue can be easily moved from place to place on your patio or deck. This 3-burner gas grill’s folding side tables make it easy to store in your garage during the winter months without taking up too much room. When unfolded, they may be used for meal preparation or serving food hot off the grill when ready.

This model’s stylish design and small dimensions will appeal to anyone who wants an excellent three burner gas grill without spending a lot of money on one. Keep in mind that you will have to purchase a gas regulator separately in order to use this appliance safely.

How To Choose The Best 3-Burner Gas Grills


It can be easy to get caught up in the excitement of finding your perfect grill, but remember that you don’t have to spend a ton of money just to get the right one. The only real rule is that you should get what you pay for. A $50 grill is going to work poorly and not last long, while a $1,000 grill will have better performance, durability and quality.

But unless you are feeding an army every weekend or are a professional chef who grills for a living, you probably don’t need the high-end model. A good 3-burner gas grill can be found for less than $250. Finding the right balance is part of your research process because there are many choices once you start looking at all the options

How To Choose The Best 3-Burner Gas Grills


You’ll want to look at the BTUs of the grill you choose. The higher, the better, but keep in mind that it isn’t everything.

You may have heard a lot about BTU’s or British thermal units and wondered how exactly they are relevant to identifying the best gas grills. Well, they’re pretty simple actually. BTU is a unit of heat and can be defined as the amount of heat required to raise one pound of water by one degree Fahrenheit.

When it comes to grills, BTU is a measure of heat output from your grill—the higher the number, the more intense your grill will be able to become (and stay).

Grilling Area & Warming Racks

Choosing the best grill for your needs will depend on what you plan to do with it. If you’re frequently cooking for a large family, you’ll want a grill with a large grilling area. If not, something smaller might be in order. A robust warming rack is another great feature to have. This will let you keep food warm while still continuing to cook the rest of the meal, meaning you can serve everything at once and enjoy your meal together instead of having to wait for one person to finish cooking before serving the rest of the food.

The quality of your cooking surface can make or break your final dish, so pay attention to how well each model is made. Some grill companies use higher-quality materials than others, which can greatly change how well your food cooks and how long your grill lasts before needing replacement parts.

If searing is important to you, look into whether or not each model has its own sear burner built in—you won’t regret it!

Grill Grates Material

The material used to make the grill grates is an important factor to consider. Grills come with three basic materials: stainless steel, cast iron, and porcelain-coated. Each of these materials has its own unique qualities that you should be aware of before making your purchase decision.

  • Stainless steel grates offer good heat retention, excellent durability and easy cleaning given the right maintenance routine. In general, this is the safest option for a grill grate as it is low-maintenance and durable so it lasts longer without corroding or rusting on you.
  • Cast iron grates are ideal if you want higher heat distribution but they do require more maintenance than stainless steel grills because they can rust easily without proper care. Cast iron also needs to be seasoned regularly so that it doesn’t stick too much when cooking over high temperatures (which happens often with burgers).
  • Porcelain coated grates are non-sticky like their stainless steel counterparts but unfortunately don’t offer as much durability due to chipping away at some point during use over time; however this does depend on how well maintained your grill is kept up with regular cleaning after each use which will prolong their lifespan considerably longer than just normal wear from cooking alone would provide otherwise!

Temp Range and Heat Control

Remember, you don’t need to just look at the heat output of a grill to determine its ability to cook food. A grill with a higher BTU rating may have poor heat retention which means that it loses heat through the sides of the lid. Take into account other elements such as the construction of the lid, whether it has a double walled lid or whether there is an additional layer of insulation on it. The more insulated a grill is, the better your control over temperature will be. You want even heat distribution over your cooking surface too so you need to make sure that your grills burners are spread out evenly across your cooking surface.

Build Quality, Construction, and Material

Over the years, we have learned that a high-quality grill means it burns hot and evenly, is durable and rust-resistant and is easy to assemble. We have also found that the material used in its construction determines how long it lasts. This means that you are looking for a grill that has a stainless steel exterior and a porcelain-coated cast iron interior.

The material used in building your grill also determines how much heat it retains, so as you prepare your food, you want to look for a heavy-duty grill with all-weather protection so that the heat stays inside the grill to cook your food thoroughly. The quality of heat retention is also determined by the material used in its construction — stainless steel vs. cast iron — which means you want to keep an eye out for either one of those materials when researching which grill to buy.


The lid is one of the most important parts of a gas grill, and one that can be easily neglected. Because it has to seal so well against the heat or fire, you’ll want to take extra steps while shopping. Make sure your lid fits snugly onto your grill by trying it in store or on an angle where you can’t see inside.

Check the size and design of the lid on paper before going home with it and make sure it is mounted securely and does not move around.

Look for a lockable lid if you live in an apartment and leave your grill unattended for long periods—you don’t want someone stealing stuff from underneath your barbecue!


So there you have it! As you can see, there are plenty of options to choose from. When buying a grill, it is essential to consider what features and options you will use most frequently. You should also keep in mind the size of your family, as well as how often you plan on using the grill.

These models were chosen based on their functionality and durability. They were selected because they were top-selling products that our research has shown to be highly rated by customers as well. Therefore, we are confident that one of these grills would make an excellent addition to your home!
