A custom outdoor kitchen can add real value to your home or it can become an albatross of problems. It is in the selection of the appliances, particularly the grill that the difference is made. Built-in gas grills can cost as little as $1,000USD or as much as $15,000. They can be small and simple or gigantic, powerful and versatile. Either way, when planning an outdoor kitchen project always start with the grill. It is the grill that, like the kitchen cooktop, will be the center of attention and the heart of the structure. Buying a cheap, poorly made gas grill will cause headaches for years. Getting a good quality, durable grill will make your outdoor cooking a joy. It is important to understand that the makers of gas grill inserts do no stick to anything resembling an industry standard. There isn't even an industry standard. Replacing a grill into a custom enclosure isn't like swapping cooktops in your kitchen. It might require a complete reconstruction of the structure so make sure you get the best built-in gas grill before you plan anything else.

Best Built-In Gas Grills under $2000
It is possible to find a good quality built-in gas grill for under $2,000USD. There are actually a large number of good products in this price range. The key is to keep it small and simple and not to expect a lot of extras. This list contains a combination of stainless steel as well as cast aluminum models. While stainless steel is generally the more desired choice, it isn't always the best. In this price range, stainless steel is going to be relatively thin and while the items I have chosen use better quality metal, the cast aluminum and less shiny grills are certainly worth considering. When building an outdoor kitchen, the durability of the grill should be the most important factor. There is, as I said, no industry standardization in sizes so replacing a built-in gas grill might not be as simple as replacing an indoor cooktop.
Best Built-in Gas Grills between $2,000 and $4,000
Once we get above $2,000USD for a built-in gas grill, the options improve. These models are all stainless steel and offer larger cooking areas and better features.

Many of the items on this list are brands that come from some of the highest-end manufacturers and while well made, they are smaller and feature fewer extras. Most of the gas grills in this price range have three burners and while a few offer rotisserie burners, many do not. There are a lot of products in this range and I have selected only the ones that I believe are worthy of inclusion on this list.

They are large, powerful, and have a wide versatility of cooking capabilities. Most are part of extensive lines of outdoor kitchen appliances and accessories. You will find that most of these products come with full rotisserie systems and infrared burners for extra searing power.
