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. Great combo functionality and very versatile

    The Ninja Double Stack XL Oven & Air Fryer is a kitchen appliance that can be easily summarized as a swiss army knife for food preparation. It sets out to consolidate a handful of kitchen gadgets and mostly succeeds in replacing them. It’s not perfect in any sense, but after using it heavily for the past month I have been truly impressed with the versatility it offers. Here’s a few things I noticed and thought would be useful to share:

    Pros:
    Literally stacks a oven/toaster on top of an air fryer/oven, and does it in a useful and smart way. The smaller oven on tops boasts an array of everyday function like bake, toast for bread and bagel, reheat etc. aimed at more smaller items like snacks. The larger bottom part has air fryer, convection bake, whole roast, air roast, pizza, and dehydrate function and can handle larger items such as a whole chicken with ease
    Each oven has it’s separate control and has individual timer and temperature setting
    Temperate range is quite large: 85 ~ 450 ℉
    Has a smart sync feature that synchronizes the cooking time between the oven and can finish 2 items at the same time
    Intuitive digital control
    Seal makes smell contained in the specific oven, avoiding cross-contamination of flavor
    The door hinges are smartly designed, allowing accessing the top oven without opening the whole door, and keeping the bottom oven operation undisturbed
    Preheating is very quick
    A lot of the operations are notified by audible alarms, which keeps me aware of what’s happening
    Almost all the needed accessories were included
    A metal crumb tray that fits inside both compartments makes cleanup an easy task
    There are an internal lights that can be turned on with a switch to check the status of the cooking, and also comes on automatically when the cooking is done
    With all the functionalities it offers, it replaced my air fryer and toaster oven, and took over a look of the things I used to do with my large oven in the range
    Comes with a built-in smart thermometer that makes cooking more easier to manage

    Cons:
    The appliance is large and takes up quite some space on the kitchen counter. Even though I was aware I’m getting an “XL” oven, the overall volume it took was noticeable, so plan ahead
    The appliance is relatively heavy
    The top oven is a bit too shallow for me, especially since the wire rack is not latched/held firmly when sliding out. As a result, taking food out when everything is super hot takes a bit of maneuvering
    It would be great if the bottom oven could be accessed without opening the top portion. Not a big deal but a nice to have flexibility
    Only one crumb tray came with the oven. Even though it can be used on both ovens, and the bottom oven has a flat floor, having 2 would make cleaning mess easier
    Roast tray is not provided in the package, and needs to be bought separately
    The wire-mesh air fry basket is not non-stick. There’s a nonstick air fry basket that can be bought separately
    Sometimes using both the ovens simultaneously can be a bit confusing, especially when I had to adjust things in between

    In summary, I’m quite happy with the Ninja Double Stack XL Oven and Air fryer system, and except a few quibbles does an excellent job overall. Highly recommended.

  2. Great machine!

    This is an upgrade from our traditional air fryer. It’s probably twice the size of our first air fryer, so if you don’t have the counter space that might be a problem.

    No real setup involved. Just take out of box and remove packaging and you are good to go. It has two sections. The top is for baking, reheating and keeping warm. The bottom is used for air frying, roasting, and broiling. First use was for air frying chicken nuggets in the bottom section. it has a preheat cycle so that was new for me too…but it does seem to heat very evenly across the machine. We went to roast a pork roast but found the machine doesn’t come with a roasting pan. You have to buy that separately so we decided to wait as I ordered it. The prepackaged chocolate chip cookies came out nice and even from the top section. So far that’s all we’ve used it for but so far it’s been good.

    Pros
    -Can do two functions at once
    -Easy to use
    -Looks good
    -Food is cooked evenly
    -Comes with a internal thermometer
    -Comes with 2 racks, 2 bake pans, and crumb catcher
    -front opening door give easy access

    Cons
    -seems a little slower but does heat evenly
    -doesn’t come with recommended broiler pan

    Overall awesome machine. Not going to take a star for not coming with something because the machine functions very well and as it should.

  3. As my husband would say, it's a superior product

    We had a Cuisinart toaster air fryer oven thing and it got the job done. We saw this and it looked like it had way more functionality so we got it. We used it for the first time the other night on reheating some homemade chicken cordon bleu, it crisped it up like it was fresh out of the fryer! It was quieter than I anticipated that it was going to be, and it heated up quickly. It doesn’t take up that much more room on our counter than our old one did, and we love the double door feature. Super super happy with this! Another Ninja product for the win

  4. Pros and cons, time will tell

    MissP October 22, 2024

    First off, I am a big fan of Ninja products. I find them reliable, innovative and great additions to my cooking experiences. This unit is a serious replacement for several other kitchen appliances so I am still working with this to see if it is the answer to my down sizing. I followed the set up instructions and went online as directed. After the unit was set for its maiden run I tired several options to see if it was easy to use. It is wonderful to have a screen that is easy to read, gives great selections including syncing both top and bottom to accomplish more varied items at the same time. It is very easy to keep clean and not really noisy. Here is where my problems lie. It is a substantial sized unit, it weighs about 30 lbs and should not be restricted in venting- my kitchen has cupboards above every inch of counter space except where the sink is. Venting and a fan would be on the range..so I have to pick it up and move it to that space for use. I am a butter user…not advised with this unit due to smoking. I find the door inconvenient to use. Lastly, the quality of the items supplied is below par for Ninja. I am in the process of replacing all of them. This is an expensive appliance and can create a more efficient way of preparing food. I will come back and add to this in the future after several months of experimenting.

  5. Quick & efficient cooking

    Baking with this was a game changer. My baked goods came out evenly baked. Very pleased with the quality of the baking.

    I would shorten the air fryer time on the instructions of any food packages as he air fryer does it job quite faster than anticipated. You’ll find your cleanup of the inside of the air fryer will be more than just using an ordinary oven since the air is pushing heat all around inside to help speed up the cooking which of course ends up moving particles on your foods being cooked. Not a deal breaker, the time saved and getting the food on the plate makes it a small inconvenience.

    When cooking top and bottom you have a choice of both ending their cooking time at the same time with the push of a smart button.
    The top compartment of the oven is for baking and other options, different from the bottom options. The bottom serves as the air fryer and has other specific cooking options.

    When pushing the buttons on the top or bottom to set your cooking style, temp and time, you will first push the top or bottom button and then turn the dial to move to the indicated style cooking you want. Then press the button and it moves to the temp option and you rotate the dial to increase/decreas temp, then same for the time.

    If you’re going to use too and bottom simultaneously, then you proceed to press the bottom button and choose the temp/time as you did with the top. Then you press start.

    The oven comes with a light switch so you can turn on and off. A clean catch tray is included with an air fryer basket and 2 large trays. Two racks are included and must be used when placing trays to cook.

    The unit is heavy and sturdy and has an indicator to let you know it’s still hot after you’re done cooking to alert everyone the temperature of the unit is still hot to touch. You should unplug the unit after eat use so there isn’t accidental turn on of unit as it’s digital and can easily be turned on

    The door has a nice feature as it can open just the top to check your food while still staying closed to maintain the temperature of the bottom oven.

    I would definitely recommend this oven. It’s made cooking enjoyable and quicker.

  6. Excellent mini oven especially for apartment life

    Beradon October 22, 2024

    I’ve recently found myself living in an apartment again in a time of my life i didn’t expect, so something like this that’s a little more robust than your standard toaster oven is very welcome.

    Packaging:
    Comes in a pretty obvious black box printed for the product, if shipped to you it’s inside another brown box. Inside is of course the unit, packaged with crumb trays, racks and an air fryer basket. It’s all fairly straightforward.

    Use:
    I will say that the controls are pretty minimal, almost shockingly so, as will be obvious in the pictures. Yes there are LED displays that show up when powered on, but it really comes down to a very small number of buttons and a single dial. It’s a nice minimalistic setup, but it almost feels like something is missing when you’re looking at the front. But honestly that’s being nit picky, because if it doesn’t need it why add extraneous controls unless there’s just more features that need it. I will say the unit is pretty large so be sure you have the counter space for it.

    You can cook two things at once or two different ways with different temps. It’s rather robust for a toaster oven, having features you usually only find in full size ovens. I was able to cook two pizzas at once which was great and without having to wait forever for a full size oven to preheat and for this to do it more effectively than one at a time, it really was great.

    It’s really a very clean look and i love that the door can function as a top only door or can open both levels at once. There’s a lot of space inside so it can cook much larger things than your standard toaster oven.

    Honestly if there was such a thing as a gourmet toaster oven, this would be it. With multiple levels and separate temps it really can do a lot for something like this.

  7. If I could give 6 stars I would!

    Big J October 21, 2024
    Review source: Amazon

    I will start by saying I have looked at several kitchen gadgets and devices over the years, and few have become daily use as quickly as this Ninja has. The dual ovens are a game changer. When preparing a quick lunch or dinner for the kids I can easily make nuggets, pizza, mozzarella sticks, etc. In one oven at a specific temperature, and something else like fries or tots in the air fryer in the other. It saves soo much electricity not needing to heat up the entire full size oven for a small tray of food. Yes, I could potentially make much of this stuff in the microwave, but the texture quality that you get out of this is drastically better, and because you can cook multiple things at once it barely takes more time and effort than the microwave. Truly, I have only used my full size oven once since receiving this device, and that was to make a full size Ham. Just about anything other than major meals and liquids can be prepared with this, and even then you’ll find yourself preparing the sides with it. I didn’t realize just how much I needed this little oven until I had it!

  8. Perfect for my small apartment!

    I have a full-size electric kitchen, but honestly I just prefer to use an air fryer for cooking because it keeps my kitchen clean and the meals are easily and quickly prepared. This Ninja air fryer is a little bigger than my old Ninja air fryer but it’s more efficient and compliments my stainless steal kitchen better.

    Here is a quick breakdown of some of my favorite features.

    1. Flexdoor Feature
    It’s basically as if you have two air fryers or ovens allowing you to cook two meals simultaneously or if you just want to use in the top, you can do so without having to use the bottom section. I can make my veggies at the top and my salmon in the bottom and there is no smell crossover.
    2. Cooking Options
    The Ninja Double Stack XL has 12-in-1 options. Basically anything from baking to broil to air fry to dehydration. I have used the brake, broil, toast, air fry and pizza option, and it cooks to my expectations. We will see how clean in stays but for now it’s not too messy.
    3. Capacity
    Depending on the size of your kitchen this could be a downside, I live in a 1200sqft apartment, but the air fryer doesn’t look too big in my opinion. I like the capacity because I can make my meal and my partners without having to really take turns deciding what to cook. Saves time and lets us eat our food nice and warm!
    4. Easy to Use
    This air fryer has a lot of options but it’s easy to use and the controls are not confusing.
    5. Build Quality
    Over the years, I’ve grown to be a fan of Ninja products and this air fryer continues to have the built quality as many of their products. The stainless steal is easy to clean and the air fryer is sturdy. Loving it for the first couple of weeks!

    Overall, I am happy I upgraded air fryers and I enjoy that I can cook faster and yet keep my kitchen looking clean! I recommend this for a household of 1-3 because you can cook multiple meals, but if you are a bigger family it may be harder to cook all your food in one setting.

  9. Really big but highly usefull!

    In the last few years, I have fallen out of love with a microwave. I have found that I would rather spend the extra time cooking or reheating food in my oven or air fryer. This is great for both! It takes up about the same counter space as my toaster oven does now, but it is taller. It’s worth it though. It cooks great and makes it so I can cook multiple things at once. This will be great this holiday season combined with my double oven; I’ll be able to cook 4 dishes at once.

  10. Incredible device, its huge though

    TJ October 19, 2024
    Review source: Amazon

    So this countertop oven does some amazing stuff. Mostly right now I’ve been toasting bread and reheating things. Nothing really major just mostly using the top toaster part. One thing to note is that this thing is huge when it’s slid under the cabinets on the counter it’s about 2 inches from hitting the cabinet underneath. That’s OK because I just basically slide it out anyways I have undercabinet lighting and if it gets hot, it’ll warp and damage the lights so I slide it out to the edge of the counter. Use it once it cools off, slide it back. Just note that this thing is literally the size of a microwave. And I actually have a microwave that’s a microwave plus a convection oven already and it’s smaller than this thing. So just know it’s gonna take up a lot of counter real estate.
