Gets the job done, spacious, quick and easy to use

My wife and I have wanted an Air fryer for some time now we finally settled on the Ninja one reason is we wanted to be able to cook 2 things at once and the double stack is a counter top space saver simple ease of use and being able to cook 2 different things at the same time is utterly the best idea I've seen in a while either basket produces a well cooked meal at the same time and one thing I'm very happy about is French Fries that are perfectly cooked but with no unhealthy grease I give this air fryer a 5 star review get yours today you won't be disappointed.

This Ninja stackable smart air fryer is great for anything family. With the the built in thermometer and multiple settings. This is the only appliance I now use in the kitchen

Great air fryer. Ninja is the standard and you really can’t go wrong with this, especially if it’s on sale. Cook amazingly, food is always tender, fully cooked to perfection. The stacking helps with counter space as well.

Excellent size as it’s not bulky and works great! It saves some counter space and fits nice and snug. The quality of the air fryer is most certainly an upgrade from our previous one by dash:). I thought the price point was a little high, but if you think about all the settings it has and for all it does, the additional thermometer included and basket racks, it’s a stand alone replacement for an oven! I love to make dehydrated fruit snacks as well and this machine does that too!

Love it! Cook’s a complete meal in about an hour and easy to clean.

We’ve been really happy with this Ninja air fryer. The two baskets are a huge plus, especially with the Smart Finish feature so everything finishes cooking at the same time. I love that there’s no preheating, which makes it quick and easy to use. I also really like that it’s designed taller instead of wider, so it doesn’t take up as much counter space. We still use our older Ninja for grilling, but this one is perfect for everyday air frying.

This air fryer is AWESOME. I love the ability to use one or both zones and the smart finish feature is awesome. I have absolutely no complaints about this

My favorite kitchen gadget. It makes my food cook itself without any effort.

Very good quality, big capacity and work well. We don’t want to cook meat in the regular pan, we just use this air fryer.

Doing its job! Good size, addition to my collection. Thanks!

The best air fryer ever ,, easy to use and easy to clean ,, has a great options

I've owned and reviewed several air fryers over the years, and now I’ve had the chance to try the new Ninja DoubleStack XL. In my opinion, Ninja makes the best air fryers on the market, and this model is no exception. However, despite its quality, it didn’t replace my older Ninja Dual Zone air fryer not because it’s a bad product, but because it didn’t meet my personal expectations. Let me explain why. Like all air fryers, this one is very straightforward to use. You simply place the food inside, set the time and temperature, and you're good to go. The only time I needed to check the manual was to figure out the smart thermometer feature. One of the main highlights on this device is the double stack design which claims to be space saving. Thanks to the large size, you can cook 4 meals at once. Each basket comes with a meal rack that is placed above the crisper plate. That rack is use to cook the second meal in the same basket. The baskets are large enough that it could fit an entire 5 lbs chicken in each. When it comes to cleaning, that non-stick coating they use is one of the best. Pour some hot running water and watch the grease come off on its own. I also appreciate the removable rubber bumpers on the crisper plates, which make cleaning even easier. This air fryer is very versatile. It has 6 different types of cooking settings. Air fryer, air broilers, roast, bake, reheat and dehydrate. There’s no preheating required, and it gets hot pretty quick. You have the ability to make the meat even crispier by reversing the crisper plate and placing it higher in the basket. The smart thermometer which I usually don’t use but I tried it here, and I was very impressed. I really like how the device will stop on its own once the meat reaches the desired temperature. I have to say it is very accurate. The meat came out at the perfect cooking temperature. The control panel, located on the right, is sleek and modern, and the large, bright display makes it easy to read. Now, here’s why this seemingly perfect air fryer didn’t quite meet my expectations. While Ninja’s cooking performance is reliable, I found myself working harder with the DoubleStack XL than with my older Dual Zone model. I had to add extra cooking time and flip food more often. This issue lies in the design. The heating coils and the fans are in the back pushing the hot air forward. I thought that the food placed close to the back was going to overcook because it was closer to the heating coil. To my surprise it was actually the opposite. The food near the front of the baskets cooked faster than the food in the back, so I had to frequently rotate the food to ensure even cooking. I thought it could have been user error but I ended up doing some research and some other users mentioned this issue. I even consulted the manual, which suggests shaking the food three times during cooking, more than the single shake required with my old air fryer. The design claims to be space savings, but that depends on your kitchen layout. In the U.S. a typical countertop length is around 25.5 to 26 inches deep. This air fryer measures about 18.5 inches from the back to handle, 11 inches wide including the control panel and 15 inches tall. That 18 inches will only leave you with less than 7 inches of space in front of it, that's barely enough room to even place the basket. My old air fryer is about 15.5 inches to the side and about 13 from the back to the handle. That’s almost about 12 inches of working space left on the front of the appliance. Additionally my old unit fan exhaust is in the back. I have the ability to slide the appliance forward to give room for air flow when cooking. As compared to the DoubleStack the exhaust is on the side meaning the space you maybe saving is for airflow. In my opinion, in terms of space efficiency, you may save width, but you lose out on length and height. Depending on your kitchen setup, this could either be a convenience or a drawback. Personally, I prefer more working space in front of the appliance rather than saving a little width on the side. Another design issue I encountered was the difficulty of flipping food from the bottom basket. With my old air fryer I could easily slide out part of the basket and perform that task, avoiding spills and of course convenience. I cannot do this with this air fryer because the handle from the top basket is in the way forcing me to fully remove the entire basket. I tried the top but honestly I found it inconvenient because of the height and the distance between the top cabinets. Lastly, the noise level was a bit of a concern. While all air fryers make noise, this one starts quietly but gets louder, almost like a turbine. It’s tolerable, but louder than other air fryers I’ve used. Overall this Ninja DoubleStack XL delivers Ninja’s usual strong performance even if it requires a little bit more handling. It is very easy to use and cleaning it is a breeze. Its versatility and ability to cook multiple meals at once makes this perfect for large families. Its sleek, modern design could fit well in many kitchens if you have the right space. I wanted it to win my heart but I’ll go back to my old Dual Zone. In the box you get the air fryer, 2 baskets, 2 crisper plates, 2 crisper grills, smart thermometer, and manuals.

Great product. Worth the money, wife is really happy.

Love it and use it on a daily basis being on my diet.

I absolutely love this purchase! Being able to cook 4 separate items at the same time!!! Love it ! The cool down feature is great as well.

It’s my first air fryer so I am enjoying it. The buttons needs to be improved

Had the previous ones and this one is the best. Food comes out delicious.

I've been using the Ninja DoubleStack XL for around a week and It's instantly replaced my oven for my everyday cooking needs. I have 3 kids, which makes dinner time extremely challenging - especially when each kiddo wants something different to eat. The DoubleStack XL solves this by allowing me to cook multiple meals at once. This Air Fryer has been an absolute game-changer in my kitchen. I can't praise this air fryer enough for how the baskets are configured. I skipped getting the other model where the baskets are side by side because counter space in my kitchen is limited and I could not justify committing so much space to one appliance - this DoubleStack solves that. While it is larger than I was expecting, the fact that it takes up so much less space than other appliances on the market is fantastic. I have not had the need to utilize the thermometer yet, but It's definitely a nice to have in the event I eventually need it to cook larger cuts of meat. That being said, do keep in mind that the thermometer can only be used on the lower basket. I don't see this being an issue but I did initially think that I would be able to use it on the top or bottom basket. Not a deal breaker by any means but just something to keep in mind. I did see some other reviews about this air fryer not cooking evenly but that has not been my experience. Even when loading the baskets and using the racks, I have not had any issues. My guess is that people might be overloading the unit and not allowing the hot air to circulate properly. One design feature I appreciate is that the hot air seems to vent from the side rather than the back. This is great because you can butt the Fryer against the wall without fear of extremely hot air blowing on your backsplash or wall. The display being mounted on the side also helps because it doesn't allow you to nestle the unit close enough to anything where I think it would cause any issues. I wanted to touch on the features that mattered most to me and my use but this Ninja DoubleStacked XL is packed with tons of features that I have not had time to use. So far, it does what I need it to do and it does it incredibly well. This is hands down the best Air Fryer that I've personally used. Controls are simple to understand, it's easy to clean and, best of all, it doesn't take up much counter space. This is a home run for Ninja and I highly recommend you consider it for your next air fryer.

Either I hadn’t been paying close enough attention these last few years, or air fryers have truly come out of nowhere to be one of the most popular, en vogue appliances since the drip-brew coffeemaker was introduced in the 1970s. Having heard the praises of air frying from countless friends and family, I finally caved, and a short while later the opportunity to get this model arose. The Ninja DoubleStack XL is a 10-quart air fryer with dual cooking compartments, each about 6 quarts that result in the combined/rated capacity of 10 quarts. Boasting an array of features that promise to make multi-course cooking simpler, and with cooking capacity enough to feed an entire family, this digital air fryer sits firmly up in the MSRP stack alongside premium options. Ninja’s appliances have a good reputation for quality, and indeed, the DoubleStack XL has been great to cook with. - Unboxing and Setup Arguably the tallest small appliance in my kitchen, the DoubleStack XL air fryer is a fairly large device that somehow still fits under my cabinets with a couple inches to spare. You’ll want to ensure that you’re positioning the air fryer somewhere that the exhaust vents on the rear right side aren’t obstructed in any way, and that where they’re pointing is OK to have heat blown right into it, as the air fryer exhumes hot air after it circulates through the basket. The Doublestack comes completely assembled, with initial setup simply asking for removal and washing of all the device’s baskets, racks, plates, and accessories prior to use. Once dried and all are replaced, the quickstart guide contains sample recipes and suggested uses for the air fryer, including how to program for dual-zone cooking with equal end times. All told it was about 10 or 15 minutes before I was set up and cooking my first whole, small chicken, which came out as good as I could ask for given my inexperience with air fryers. The biggest trouble I ran into getting started is that the quick-start documentation is poorly published and difficult to follow. Attempting to follow along for my first meal using the sensor cook, I found the written instructions made several assumptions about replacing baskets, trays, or basket mesh that a novice user would struggle to understand, and at one point confused basket #1 with basket #2. While both quickstart instructions and the user manual would benefit from sanity checks and/or better proofreading, the quickstart would be much easier to follow (and much more accessible to those who may not read or understand English as their native language) with diagrams or illustrations showing key steps and display functions. - Cooking Impressions The first time I used the Doublestack, I was a bit surprised by the noise it creates. I know air frying needs a strong convection fan to force hot air through the fry baskets, and perhaps the fan on my model is very slightly out of balance…but once the fan approaches full speed it’s quite noticeable and easily the loudest appliance in my kitchen, save for the grinder on my espresso machine. Once you understand the control panel (a little trial and error may be necessary due to the quickstart confusion), it’s easy to set the Doublestack like it’s a toaster oven or similar appliance. Set mode, temperature, and cooking time, then press Start. The benefit of an air fryer over a conventional oven is that preheating is so quick as to be almost unnecessary, and indeed you can simply insert food and start air-frying without warming the basket up first. In any case, the Doublestack works quickly and the end result is crispier food than what would be prepared in my toaster oven, though I do feel my traditional oven (with convection) still does a better job for roasting and baking. Anything that leans towards frying, however, comes out much better in the Doublestack. Plus, there’s no need to worry about deep-frying grease from the perspective of either cleaning up or sheer caloric detriment - a win-win in my book. Overall, I found that cooking times with the Doublestack tend to be a bit longer than either the food manufacturer or Ninja recommend. Adding an extra few minutes to any meal cooked in the air fryer seems to be necessary, regardless of whether one basket or both are in-use. This may be specific to air-fryers in general, however - both baskets cook consistently and evenly otherwise, and as I gained familiarity with the machine I settled on an additional 3 minutes for small baskets and 5 for big ones, which seemed to deliver perfectly crispy results. Sensor cooking did not need adjustment. - Modes & Programming The Doublestack does more than just air-fry. Featured cooking options include air-broiling, roasting, baking, dehydrating, and reheating. These all work similarly to a conventional toaster oven, changing the fan speed, heating element strength, and overall flow of heat and hot air through the baskets to create these additional functions. While I haven’t used these functions just yet, they’re nice to have and with enough time, may be what makes me wind up replacing my toaster oven with the DoubleStack XL after all. Beyond one-touch sensor cooking for perfectly air fried meats, the DoubleStack’s most useful feature is the fully independent control of both cooking baskets. Match Cook simply synchronizes basket 1’s settings to basket 2’s, effectively doubling capacity for cooking large meals, so long as what you’re cooking fits within a basket…you won’t fit a full-size chicken in the air fryer, but two small “whole young” chickens is viable. The more useful feature is Smart Finish, which lets you set a different cooking mode and time on each basket, with both baskets finishing simultaneously (or as close as possible). This makes it possible to cook two items in parallel, even if they call for different cooking temperatures, and only need to load and set the machine once. This came in handy preparing fries alongside chicken, as a recent example, and without any guesswork both courses finished cooking within seconds of each other. Load once, cook once! - Cleaning & Care The Doublestack XL is relatively easy to clean. The basket trays and wire racks are machine-washable, but the baskets themselves and integrated meat thermometer must be washed by hand. In any case, the nonstick surfaces of the baskets make them quick and easy to clean in the sink, though my fiancee did notice it can be tricky to clean around the rubber stoppers of the basket trays. All in all it’s one of the easier of our small appliances to clean. *As I was finishing this review I noticed that the user manual and Ninja’s website differ on whether the baskets (drawers) are machine-washable; the website indicates they are, but not the user manual. I’m hoping a Ninja product rep can clarify in a comment on this review. - Bottom Line Having never used an air fryer before, the Ninja DoubleStack XL Air Fryer has been a great introduction to air-fryers that, despite a few shortcomings in the documentation and first-time user experience, has sold me on air frying despite years of resistance to picking one up. It’s intuitive to use once you fill in the gaps, the food that comes out of the machine is evenly heated, the air frying makes for wonderfully crispy meals, and cleaning is straightforward. I couldn’t ask for much more - but the asynchronous controls over both baskets made this a real treat to use for cooking entire meals instead of individual courses all at once. With only a couple small detriments, none of which are a dealbreaker or negatively impact its cooking performance, the Ninja DoubleStack XL comes recommended!
