Unlock the power of two ovens in the counter space of one with the Ninja Double Stack XL Countertop Oven & Air Fryer with Pro Cook System. 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 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 with DualZone Technology. While your meal cooks, FlavorSeal technology prevents flavor crossover between ovens. Two cooking zones in one eliminate back-to-back cooking for 65% faster meal-making than your traditional oven. The Pro Cook System with Auto Detect Intelligence precisely monitors temperatures, so you don’t have to. Plus, this countertop dual oven features 12 cooking functions for the ultimate versatility.
