The Ninja FlexFlame is a versatile 5-in-1 outdoor cooking system that combines grilling, smoking, roasting, griddling, and pizza making capabilities in a single propane-powered appliance. The grill features precise temperature control from 200°F to 600°F, allowing you to dial in and maintain exact cooking temperatures for any style of outdoor cooking. The system's standout feature is its high-velocity convection fan that continuously circulates heated air and smoke throughout the 424 square inch primary cooking chamber, eliminating hot spots and ensuring even cooking across the entire surface.

The FlexFlame includes a built-in smoke box that holds wood pellets and an auger system activated by the Woodfire button, adding authentic wood-fired flavor to any dish. The grill outputs 37,000 BTU from three burners and can reach maximum temperature in under 10 minutes. The digital control panel features intuitive function and temperature knobs similar to a countertop smart oven, with an LCD display showing both current and target temperatures. Multiple cooking modes include grill/pizza, two-zone cooking, roast/bake, and low & slow cooking for traditional BBQ styles.

The included accessories comprise stainless steel grates, a half griddle, weather-resistant cover, expandable roast and smoke rack, two bags of wood pellets, and 10 grease tray liners. Additional optional accessories expand functionality further, including a 16-inch artisan pizza stone, full-size griddle, and premium half griddle. The grill provides 544 square inches of total cooking space including the 120 square inch secondary rack. Assembly takes approximately one hour with only a screwdriver and bolt tightener required (both included). The unit measures 59.57 inches in length and weighs 130 pounds. Requires both propane connection (tank not included) and standard electrical outlet for convection fan and electronic ignition.
