Highlights

FlexDoor™ Dual Oven Design The innovative FlexDoor™ creates two independent ovens in one compact footprint, allowing you to access just the top for quick snacks or open the full door to cook two complete meals at different temperatures and settings simultaneously.
Smart Finish™ with DualZone™ Technology Eliminate back-to-back cooking by syncing both independent ovens to finish at the same time, even if they require different cooking functions, temperatures, or durations.
FlavorSeal Technology Designed with two separate cooking environments, FlavorSeal technology prevents smells and flavors from transferring between the upper and lower ovens, ensuring your main course and dessert stay distinct.
12-in-1 Versatile Functionality This all-in-one appliance offers 12 versatile programs including Air Fry, Convection Bake, Whole Roast, Air Roast, Bake, Broil, Pizza, Toast, Bagel, Reheat, Keep Warm, and Dehydrate.
XL Family-Sized Capacity The spacious interior is designed for large families, fitting up to 6 lbs of wings, a 4.5-lb whole chicken, two 12-inch pizzas, or full sheet pan meals across its two cooking zones.

Pros & Cons

Pros

  • Dual-Zone Versatility: The independent top and bottom ovens allow users to cook two different dishes at different temperatures and settings at the same time, effectively replacing multiple appliances like toasters and air fryers.
  • Smart Finish Technology: The Smart Finish feature is a major highlight, automatically synchronizing the cooking times of both ovens so that different foods are ready to be served at the exact same moment.
  • Fast Preheating and Cooking: Reviewers frequently note that the unit preheats in just a few minutes and cooks food significantly faster than traditional full-sized ovens, making it highly efficient for daily meal prep.

Cons

  • Difficult to Clean: The interior lacks a non-stick coating, making it tough to scrub, and the downward-opening door design allows crumbs and grease to fall into the hinges and crevices.
  • Inconsistent Toasting: Many users report that the toast and bagel settings are too powerful, often burning the edges of bread or producing 'nuclear' heat even on the lowest shade settings.
  • Bulky Size and Hot Exterior: The appliance takes up substantial counter space and is quite heavy; additionally, the exterior surfaces become dangerously hot during operation, posing a potential burn risk.

  1. Awesome cooking power

    With the twelve different cooking styles and two independent ovens you’ll be able to cook just about anything in this unit. Easy to set up cooking schedule not as easy to clean but if cleaned after each use not too bad. Bought some parchment liners and silicon ones also which helps keep interior cleaner. Overall a great oven. Does everything my large conventional oven/stove can do in a space that takes less energy to use. Side note: could cost less as it is a bit pricey. Dropped a star only because of the price.

    The Ninja Air Fryer and Toaster Oven has been a game-changer in my kitchen – seriously, five stars all the way! First off, its versatility is unmatched. I’ve used it to air fry, bake, and roast, and it handles everything with impressive results. From crispy fries that rival any restaurant’s to beautifully roasted chicken and perfectly baked cookies, this appliance delivers every time. Oh, and it looks great on my countertop!

    When we open the box, it was missing a thermometer and two cooking trays. We called ninja and they took care of the problem and sent out the replacements. After learning the features, it’s become a very necessary appliance in our kitchen.

    Top section could be deeper. Also I put a potato in the top to bake and after 45 minutes was not getting done. Had to put in the bottom. Have to watch or some foods start to burn. I would not buy this oven again.

    For the first few weeks, it runs very hot so be careful. Helpful hint: pushing it’s respective button twice, after start, let’s you adjust the time and temp settings.
    But overall, it is a great buy
