These are the best, most expensive gas grills on the market. I've included a wide range of prices, but if you are looking here, price probably doesn't matter much. In the Best Gas Grills over $8000 you will find top quality stainless steel construction, large cooking spaces, and loads of features. There are grills with remote lid lifters, wi-fi and Bluetooth connectivity and even smart grills that can adjust their own heat and monitor for flare-ups. Typically these grills are not going to be sitting on rolling carts, but are built for the outdoor kitchen market and most of them come as part of a package of products that can reach into the tens of thousands of dollars just for the appliances. I've listed a wide range of products to help you see how they match up. Most patio stores and landscapers will only work with a few brands, but there is more than a dozen out there. It is best to shop the prices, brands and understand the quality before spending all this money.
At well over $25,000USD this is the most expensive gas grill on the market (not counting the four burner version). But more than being a status symbol, the Kalamazoo is a powerful grilling machine. As a true hybrid grill, this model can burn practically any fuel, has an impressive rotisserie system, and a pair of high power side burners. Whether as a standalone grill, or part of a full outdoor kitchen, this is the grill to aspire too.
Fire Magic Diamond Echelon E1060S
At nearly ten feet end to end, this grill has it all, and what it doesn't come standard with, can probably be added on. Four burners can pump out 110,000 BTUs under the more than a thousand square inches of primary cooking space. That's about seven and a half square feet of cooking space. Add into this a supercharged side burner whose two burners can pump out 60,000 BTUs and you have one of the largest, most powerful, and most versatile gas grills on the market. At around $13,000USD depending on configuration, it isn't cheap, but you actually get your money's worth with this grill. Fire Magic is a powerhouse in outdoor cooking and has been around for decades. They dominate the high-end grill market with their superior products and one of the largest lines of outdoor kitchen appliances.
Twin Eagles 54-Inch
Looks are a matter of opinion, but in my opinion, the Twin Eagles Gas Grills are the best looking in the world. But appearance is only part of the picture. This four burner gas grill has power, superior construction, and an obsessive attention to detail. Designed by Dante Cantal, the da Vinci if grill design, this gas grill offers exactly what the serious outdoor chef wants, a grill that works beautifully. This is the largest models of this grill, and like the others on the list comes as part of a collection of outdoor kitchen products (all equally impressive in design). This monster of a grill offers 1000 square inches (nearly 7 square feet), making it one of the largest gas grills on the market. Give Twin Eagles a look. You won't be disappointed.
DCS Series 9 Evolution 48-Inch
If anyone can be credited with creating the high-end outdoor kitchen market it is DCS. Of course, DCS makes more than just a wide range of outdoor kitchen products. They are well known and respected for professional and high-end traditional kitchen equipment. This model, the four burner 48-Inch gas grill, pumps out 100,000 BTUs under 855 square inches of cast stainless steel cooking grates. Many companies have reproduced and then tried to improve upon this design, but the original remains one of the best gas grills on the market. Interestingly, at around $9,000USD this model is one the least expensive grills on this list. DCS is a great choice, though some of its design features are a little odd. One example is the angled cooking grates which drain away grease but allow anything round to roll off the grill.
Relatively new to the market, the Hestan product line has quickly emerged as a serious competitor. With an innovative design, the nearly $12,000 (depending on configuration) gas grill comes in multiple colors, heavy construction and a wide range of features. In the standard configuration, this grill comes with four 25,000 BTU burners (any number of which can be swapped for infrared burners). This gives it up to 100,000 BTUs under 774 square inches of primary grilling space. This is a lot of power. Add to it two side burners and an infrared rotisserie burner and this is one hot grill. The cooking grates are thick stainless steel plate. One standout feature of this grill is that the rotisserie burner is top mounted and can be used not only for rotisserie cooking to as a salamander style broiler.
Alfresco ALXE 56-Inch
Alfresco makes one of the largest lines of outdoor cooking appliances. Building an outdoor kitchen? They have practically everything you need. At around $9,600 this 56-inch gas grill isn't inexpensive and neither is the rest of the product line, but this company brings decades of experience to the market. In fact, Dale Seiden, the head of Alfresco used to run Lynx. This 82,500 BTU powerhouse packs in all the features imaginable and has one of the best warranties in the industry. I like the built-in double side burner on this grill that makes this freestanding model a full feature unit.
Caliber Crossflame Pro 60-Inch
The Caliber Crossflame 60-Inch is a monster of a grill. It has 7 feet of primary grilling space and stretches 8 feet end to end. But it is in the features that this grill stands out. This model has two, powerful side burners, a full rotisserie system and two level cooking grates that let you do standard grilling, or get down closer the burners for a more intense sear. The construction quality is excellent and, of course, this grill comes as part of a large range of outdoor cooking products. At around $12,000USD this is also one of the most expensive grills on the market. I mean, you can spend more as this list shows, but you don't have to.
American Muscle Grill 36-Inch
Like that Kalamazoo at the top of this list, the American Muscle Grill is a hybrid grill. It has powerful gas burners, but will also burn charcoal or hardwood. Built to look something like a 1969 Shelby GT 350 Mustang, this grill is packed with muscle. The five main burners can generate 110,000 BTUs under 720 square inches of stainless steel cooking area. With all this power, on gas alone, it can hit ridiculous temperatures in minutes and is constructed to take the punishment. As a built-in or freestanding grill, this is the epitome of 'more power' and like a muscle car, it delivers that. Subtle, this grill isn't.
