Meet the Ninja Double Oven, the countertop oven that unlocks the power of two ovens in the counter space of one. Only Ninja has the FlexDoor that creates 2 separate ovens so you can cook 2 meals, 2 ways at different temperatures and cooking times. Use just the Top Rapid Oven for quick snacks, sides, and sheet pan meals—or the Bottom Convection & Air Fry Oven for larger roasts, bakes, or air frying up to 6 lbs of wings.

You can also sync both independent ovens to cook a full course meal that finishes cooking at the same time with Smart Finish technology. While your meal cooks, FlavorSeal technology prevents flavor crossover between ovens. The Smart Cook System precisely monitors temperatures with the leave-in thermometer, so you don't have to.

Two oven cavities in one eliminate back-to-back cooking for 65% faster meal-making than your traditional oven so you can put your wall oven out of
