Best 3 Burner Gas Grills – Picks for 2020

If your exterior isn’t large, there’s no need to get a large grill that will take up all of the space; get a 3-burner grill instead. It has great cooking ability and its size is perfect for small spaces. When vetting the best 3 burner gas grills, I eliminated all the rest and chose these 5 that are truly impressive.

The Genesis II LX S-340 by Weber costs a pretty penny (it’s the most expensive on this list) but it’s wonderfully constructed. Its 3 burners churn out 43,500 BTUs and its primary cooking area is 513 square inches. Backed by Weber’s 10-year warranty, it truly is the leader of the pack.

The 32,000-BTU Spirit E310 by Weber is also a masterpiece. Its users love the way its flavorizer bars help meats to retain all their flavors. Its porcelain-coated cast iron grates are very easy to clean.

If you are looking for a grill with premium features, the Signature TRU-Infrared 420 by Char-Broil is yours for the taking. It uses Char-Broil’s TRU-Infrared technology, giving you greater temperature control and grilling your food evenly.

Two Dyna-Glo grills complete my list: the Smart Space Living DGB390SNP-D Grill and the Smart Space Living DGB390BNP-D Grill. They both have 507 square inches of total cooking area and their 3 burners produce 36,000 BTUs in total. However, the Smart Space Living DGB390BNP-D Grill is pricier and has a unique brown color.
