Grilling is one of the most fulfilling and enjoyable ways to cook your meals and what better way to grill than with a built-in unit? The best built-in gas barbecue grills are sturdy and well-performing, and allow you to customize your grilling environment.

Referencing our grilling experience, we’ve compiled a list of the best built-in grills based on their specifications from BTU/hr to cooking space, etc.

By comparing some of the top models available, you’ll be able to find the perfect grill for your needs. Let’s check out the top three recommendations before jumping into the list.

Our Top Recommended Built-in Gas Grills

• The first: the top-recommended built-in grill is the Napoleon Grills Built-in Prestige 500 with Infrared Rear Burner Propane Grill. This unit has the exceptional heating quality and does so over a large, 760 square inch total cooking space. In addition to its four burners, it also has an infrared rotisserie system, allowing this propane grill to do more than just grilling.
• Our second: top recommendation is the KitchenAid 740-0781 Built-in Propane Gas Grill head. This unit also does a phenomenal job with heating as it pumps 71,000 BTU/hr utilizing only four burners! Not only that, but this model has a slightly larger cooking space than the top Napoleon model at 930 square inches. The KitchenAid 750-0781 also comes with a 10-year, main burner warranty.
• Our third: and final top recommendation is the Weber Summit S-460 Built-In Natural Gas Grill. This trusty Weber grill also sports four burners, as does the KitchenAid unit, but it only produces roughly 48,000 BTU/hr, which is still impressive but doesn’t touch the market’s upper ceiling for this spec. This unit, however, comes with a bevy of cool features that make grilling easy and hassle-free. Now let’s get right into the full list.

The 10 Best Built-in Gas Grills:

1. Napoleon Grills Built-in Prestige 500 RB with Infrared Rear Burner Propane Grill

10. Alfresco ALXE-42-NG 42 Standard Grill

Factors to Consider When Buying Built-in Gas Grills

The following is a list of factors to consider when buying built-in gas grills:

A number of burners & BTU/hr:

The first and most important factors to consider when buying a grill are the BTU/hr production and the number of burners.

While most times the burners will more or less translate into particular BTU/hr specs, some models display greater or lesser efficiencies.

For instance, the grills with a BTU/hr spec of 60,000 or greater are among the most powerful models on the market. And to the burner efficiency point, some models can accomplish these specs with only four burners while some require five.

Generally speaking, you want the highest BTU/hr model you can find that fits your other preferences.

Total cooking space & size:

The next set of factors to consider before buying a built-in grill relates to size. The first is its cooking space. Obviously, the larger the cooking space the more you can cook at once.

Be wary of how these cooking spaces are set up, though, because sometimes the warming rack is larger and that can deceive you about the main cooking space.

The next thing to consider is the dimensions. The dimensions of each model will determine the assembly and construction of your built-in grill space.

Therefore, dimensions may be the most important factor to consider for the built-in grills, period.

Interior grill set-up:

The interior grill setup is the final factor to consider for your built-in grill.

What’s meant by the interior set-up is the size and orientation of the warming rack, the style of the cooking grates, whether or not there’s a rotisserie kit (infrared burner or actual kit), and how the burners are oriented and situated among other things.

While these things may seem inconsequential, they’ll help you ensure you’re getting something you’ll be absolutely satisfied with.

Conclusion

In conclusion, the best, built-in grill for outdoor kitchen setups is the Napoleon Grills Built-in Prestige 500 with Infrared Rear Burner Propane Grill.

This Prestige 500 comes at an affordable price, produces an impressive 66,000 BTU/hr, and utilizes a five-burner and infrared burner system.

If you’re looking for something with a little less size that still packs a punch, give the KitchenAid 740-0780 Built-in Propane Gas Grill a good look.

This grill unit pumps an impressive 61,000 BTU/hr on only four burners and also comes with a 10-year warranty for the main burners. However, as the list tells us, there are plenty of quality models on the list so don’t limit your scope.

Regardless of the model you choose, a built-in grill will bring you exciting cookouts and parties, a cozy and custom cooking setup, and intense grilling power. So, what are you waiting for? Get your built-in grill today!
