Best 3 Burner Gas Grills | Get the Right Balance in Cooking

Today, there are tons of different variations for gas grills. Most often than not, we tend to consider the more obvious factors such as size, material, cooking power and price. While the number of primary burners in a gas grill is sometimes overlooked for the number of BTUs a grill can dish out, they are just as important! Thus, we’re taking a closer look at the best 3 burner gas grills in the market that I recommend the most.

First of all, when we speak of the ‘primary’ or ‘main’ burners, these are the ones under the cooking grate which we actually use for grilling. Secondary burners like side burner, rotisserie burner and more, aren’t exactly a real need to grilling, yet, quite a treat to have around. So when looking for a great grill, it may or may not include secondary burners. But when they do, it’s gonna be a big plus point!

On the other hand, if you’re still wondering what’s so significant with the number of burners a grill has? Simply put, the more burners a gas grill has, the more versatile and diverse it becomes.

More burners could mean faster heating time and make better use of zone grilling. Don’t get me wrong, 2 burner grills can already achieve a direct and indirect cooking. But with 3 or more burners make it easier and can create a range of grill zones from low, medium to high heat. This allows you to cook different food at different heat levels at the same time. So if you need to sear a couple of steaks over a high heat while cooking the side veggies at a lower heat, you can perfectly do so.

If you’re on a budget or still prefer to have a compact grill, but wants a more diversified grill, a 3 burner grill makes a great starting point. So to make the search for the best 3 burner gas grills short, allow me to introduce you to my top 3 picks! All of which have a powerful cooking prowess and are definitely a premium in grilling technology. So without further ado, let’s get down to the nitty-gritty of each grill.

The Top 3-Burner Gas Grills Picks and Reviews

Weber Genesis II LX S-340 Liquid Propane Grill

Starting the list strong is from none other than the brand Weber! Anyone who’s a grill enthusiast would know the name. After all, it’s been around since 1952 by George Stephen and continues to develop the gorgeous grills we’ve been enjoying today. Weber is also a proud American brand that guarantees quality and celebrates the joy of grilling anywhere any time.

When it comes to 3 burner gas grills, Weber has a lot to offer from the Spirit II line to the Genesis II series. But among them, the Weber Genesis II LXE S-340 stands out the most as it’s also the highest-end among the range. Unfortunately, it also comes with the heftiest price tag. Nonetheless, its features and quality are worth the price.

The Genesis II LXE actually has 2 variants, the E-340 or the S-340. The main difference is between their composition, wherein the E is mostly with porcelain enamel while the S is clad in sturdy stainless steel. For only less than a hundred bucks more with the S-variant, you can already opt for a sleek premium look that suits almost any setting. It’s also easy to clean and maintain. Both are superb performers, so you can’t go wrong with either way.

Speaking of performance, let’s first talk about the GS4 Grilling System. The GS4 brings innovation and convenience to our BBQ experience by offering reliable spark every time to its three high-performance stainless steel burners. The grill then infuses a savory smoke flavor with Weber’s very own Flavorizer bars and ensures fast cleanup every after use.

The 3 heavy-duty stainless steel burners can generate a total cooking power of 43,500 BTUs. It’s a total powerhouse that can heat up the grill fast and sear your steak like a pro! Additionally, there is also a flush-mounted 12,000 BTU side burner which is perfect for heating anything in a pan such as sauces, sides to soups!

Made of stainless steel, the 7mm cooking grates give you a total of 513 square inches of cooking space with an additional 156 square inches of warming rack overhead. This is more than perfect for cooking for a big party. But for more intimate affairs, you can just tuck away the warming rack without a hitch!

For those new to the Flavorizer bars, these are amazing innovation you can only find with Weber. These bars catch any excess drippings and evaporate them back to add smokiness and flavor to your food. Whether it’s the E or the S variant, both of their Flavorizer bars are in stainless steel. There’s also a new Grease Management System that reduces the risk of flare-ups and also makes cleaning up the excess grease easier for you!

The Infinity Ignition makes sure that all you simply have to do is turn the knob to ignite the burners so say goodbye to manually starting it yourself. And if it ever stops working, the 10 Year Warranty will take care of the rest.

I especially appreciate some extra features such as the handle light and lighted control knobs which are perfect for grilling at night. Furthermore, you can also use the handle light during the day to help you see the rareness of the meat. It even turns off automatically to conserve energy. Furthermore, the integrated tool hooks make sure that I have most of the tools I need with me within arm’s reach. While the left side table conveniently folds down so it doesn’t take up too much space when not in use.

And just when you think there’s nothing new to find among the traditional grills, Weber once again made a breakthrough with iGrill3. It’s a modern way to monitor the real-time temperature of the food your cooking and the grill’s fuel tank level through your mobile device. I applaud how Weber makes it a point to have their grills fit with our techie lifestyle. While the Genesis II LXE E or S-340 are all ready for the iGrill3, you have to buy the accessory separately.

If there’s one thing that will hinder me from choosing this to be the best 3 burner gas grills, it is most definitely the price. Coughing up not more than $1700 can be daunting. So if you want to save up and still prefers a Weber quality, you can do away with the Genesis II E-310 which is just as powerful and heavy-duty but lacks a side burner. Still, the Weber Genesis II LXE S-340 definitely offers a great all-in-one experience for years!

The Genesis II LX S-340 Liquid Propane Grill is a beautiful steel beast that’s ready to give you a grilled feast at any time you could possibly want.

Char-Griller 3001 Grillin’ Pro 40,800-BTU Gas Grill

Char-Griller has been developing beautiful and reliable gas grills decades ago and have created various options throughout the years such as Dual Fuel, Kettles, and more!

As for this category, you can rely on Char-Griller’s 3001 Grillin’ Pro. It’s been around for more than 8 years already and it still reigns not only as one of the best 3 burner gas grills of today but also the best gas grills under $200. With over 700 customers and counting, this Char-Griller continues to receive rave reviews and remains relevant in the grilling scene, especially for those with a tight budget.

Starting with Char-Griller’s 3 stainless steel burners, they can fire up a total of 40,800 across a 438 sq. in. of cooking surface with an additional 192 sq. in. of warming rack. While it may not be as big as the Genesis II LXE, it’s still large enough to fit 12 burgers at the same time or fill up 5 stomachs in one go! Not only can you cook so many simultaneously, but you also have a handy warming rack for the finished pieces to be served.

While its firepower is more than capable to heat the grill fast and really hot. In fact, you can get this hot over 500 degrees in just 10 minutes and even hit as high as 700 degrees easy. And if you need to warm anything else up, the Char-Griller 3001 also has a side burner with 12,000 BTUs of cooking power. The gorgeous vintage look with this one clearly translates to an equally gorgeous feast whether for your family or even the whole clan!

One of the things that will probably catch your eye right away is the Char-Griller 3001’s beautifully rustic vintage look. I’m almost reminded of those old-timey black fireplaces from the 60s. This gas grill makes use of a heavy steel build – making it incredibly strong and durable.

While the Char-Griller may lack a techie feature like an iGrill3, rest assured that nothing about its features is old-timey, but rather a classic need for a grill. You can still rely on its lid-mounted thermometer to track the grill’s temperature. And aside from the burners, this gas griller has a lot of thoughtful features such as a side shelf for extra workspace, electronic ignition for fast hassle-free cooking, and porcelain-coated cast iron grates for even heat distribution and beautiful grill marks. Lastly, it also has utensil hooks to keep what you need close!

This also has a very solid steel build but surprisingly weighs less than a hundred pounds. Moreover, for WAY less than the price of the Genesis, the Char-Griller is also just as capable of grilling. Both the Genesis and the Char-Griller even have a side burner. The only question is which one could last longer.

Nevertheless, your $200 can seriously go a long way with the Char-Griller 3001 Grillin Pro. It proves to be one of the best 3 burner gas grills as it already offers plenty of features to look forward to and is just as capable in grilling as those twice its price.

You can wheel it out for a great summer barbeque and get all the fun of the outdoors with some delicious grilled meat!

The Dyna-Glo also includes a 117 square inch warming rack for you to do more than just keeping the food warm. Out of all 3, the Dyna-Glo considerably has the smallest cooking space. But that’s a compromise needed in order to achieve its compact design. Hence, among the best 3 burners gas grills around, this has the smallest footprint area to offer.

On the other hand, its heat output is more than enough to quickly and efficiently distribute high heat over its grill surface.

To help isolate the heat and maintain its consistency, the Dyna-Glo Smart Space Living makes use of a double wall stainless steel lid to keep the heat where it belongs – inside the grill and away from you! Additionally, there are also Steel Heat Tents that accompany the burners to protect the burners as well as flavor the foods. While its heavy-gauge porcelain enameled cast iron grates effectively retains heat to ensure those delicious sear marks and helps lock in the food’s natural juices.

The Dyna-Glo Smart Space Living is made of stainless and powder-coated steels for a strong and steady shape that gives you confidence as a griller and a stable cooking experience. But since not all of its parts are made of stainless steel, it may be susceptible to rust faster than the Weber. So proper care and regular cleaning are crucial. But don’t worry, it also has a removable tray under the burners with a removable cup for catching grease to make cleanup minimal.

And as a standard feature, you can find a lid-mounted thermometer to keep up with your food’s temperature.
