Double Stack XL Air Fryer, Vertical Dual Drawer Air Fryer, SL400UKCP

After four years of daily use, my Ninja Foodi MAX Dual Zone Air Fryer with Smart Cook System (AF451UK) had been absolutely fantastic and never let me down, but I decided it was time for an upgrade. The Ninja Double Stack Pro XL in Stone Gold is everything I was hoping for and more. The clever vertical design gives me all the cooking capacity I need while taking up much less space on my worktop, making my kitchen feel far less cluttered. The Stone Gold finish is gorgeous and matches my home aesthetic perfectly, giving it a premium look that blends beautifully with my other appliances. Performance is exactly what I’ve come to expect from Ninja—fast, even cooking, crispy results, intuitive controls, and easy cleaning. If you’re considering upgrading from an older Ninja model, I can wholeheartedly recommend the Double Stack Pro XL; it keeps everything I loved about my previous air fryer while improving the design, saving valuable counter space, and looking absolutely stunning.

Love this!!! The best air fryer I've ever had and I've had a few 😂 It takes up minimal space, the noise isn't noticeable at all. Easy to clean and easy to use. I normally put my food on for half the cooking time, check it and then put it back on. The bake function is brilliant as well, made a really good summer fruits crumble

THANK YOU VERY MUCH ❤️🤗 Thank you so much for this wonderful machine—it is truly amazing. It is energy-efficient, high-performing, precise, fast, and beautiful. I’ll just say this: I won’t be touching my oven anymore, as it consumes a lot of electricity and takes too long for any task—not to mention the cleanup involved. I highly recommend this machine; it is reliable and takes up very little space. Best regards.🥳😍

The Ninja Air Fryer XL works fast and cooks food evenly with a great crispy finish. The XL size is perfect for making larger portions, and it’s super easy to use. Cleanup is quick thanks to the nonstick basket. Solid quality and definitely worth the money. Highly recommend.

My old air fryer was perfectly fine. It cooked food, took up half the kitchen and generally got on with its life without causing any drama. Then the Ninja Double Stack arrived and immediately made it feel like I’d been cooking with Victorian technology. The first thing you notice is the design. Instead of spreading itself across the worktop like a stranded whale, it goes upwards. Whoever came up with the idea deserves some sort of national award because it somehow gives you two large cooking drawers without sacrificing half your kitchen counter space. It looks properly smart too. Sleek, modern and expensive enough that visitors assume you’ve got your life together. Little do they know you’re using it to cook dinosaur-shaped chicken nuggets and reheated pizza. The capacity is ridiculous. This thing can produce enough food for a family meal while occupying roughly the same footprint as a standard air fryer. It’s basically the TARDIS of kitchen appliances. The dual drawers are brilliant because it allows you to cook different foods at different temperatures and timings. No more trying to coordinate chips, chicken and vegetables like you’re directing air traffic control. Just throw everything in, press a few buttons and let the Ninja perform its dark arts. And somehow everything comes out crispy. I genuinely don’t understand how air fryers continue to get away with this. Chips? Crispy. Chicken? Crispy. Leftover pizza? Somehow crispier than it was when it arrived. At this point I’m fairly certain there’s a tiny wizard trapped inside. The sync function is probably my favourite feature. You can have two completely different meals cooking and the machine magically works out how to finish them at the same time. It’s like having Gordon Ramsay hidden in a drawer shouting timing instructions. The controls are easy enough to use, although like every modern appliance there are enough cooking modes to make you briefly question whether you’re operating kitchen equipment or preparing a spacecraft for launch. Cleaning is also surprisingly painless. The drawers slide out easily, the non-stick coating works well and most of the mess wipes away without requiring the strength and determination of a forensic investigator. The only downside is what happens after you buy it. You become one of those people. You start conversations with: “Have you tried it in the air fryer?” Someone mentions cooking literally anything and suddenly you’re giving a TED Talk about airflow circulation and crisping technology. Before long you’re convincing friends and family that buying a conventional oven was a mistake. You also start looking around the kitchen wondering if everything can go in it. Toast. Croissants. Wraps. Yesterday’s chips. Possibly small household furniture. Overall, the Ninja Double Stack is genuinely excellent. It saves space, cooks brilliantly, is easy to use and somehow makes weeknight dinners feel effortless. Expensive? Yes. Worth it? Let’s just say my actual oven now spends most of its time sitting in the corner wondering where it all went wrong.

Really impressed by the performance of this air fryer. After not having one and being on a diet and wanting to eat more healthy foods and ditch the deep fat fried foods I opted to purchase this one based on the style and compact size. I have cooked, roast potatoes for a roast, perfect. Chips are crispy and not dried out or hard. Fish cooked well as well as chicken items. Can’t wait to try everything else possibilities are endless. Don’t be put off by the negative feedback. FOLLOW THE INSTRUCTIONS and you will have perfect cooked foods. You do have to toss the food around, for example fries, I would shake and toss these around three times moving them from the front of the draw to the back during the cooking and also to check the progress of them remember you have to do this with normal ovens which say turn over halfway during cooking… It’s all about getting used to how the device works. It mostly cooks much quicker than you think, much quicker than my fan oven. As it cooks faster it does save energy which in time will pay you back not having to heat up a big oven saves both time and money. The heat up times are instant as it is compact area whereas an oven has to heat up large doors, racks, walls… The design is good looking sleek and smart fits in my kitchen nicely proud to have it out on display and not in hiding like by old fat fryer is. The control panel is easy to use. With so many functions each you can tailor temp and time. Sync and match options are great addition. You can pop the draws into the dishwasher for easy cleaning but I would suggest you hand wash these with some good old washing up liquid it only takes seconds to do this and prolongs the life of the non stick. Remember to use silicone tongs so you don’t damage or scrape the non stick. If you are thinking of buying one, I 100% recommend this one, I like buying food I can put in this just so I can use it most days! Ovens are so 2008. I’m about to register my device guarantee so I can get another years cover, another benefit. Haven’t you ordered yours yet? Tick Tock. Should have got one years ago but having said that this new design has only just been released.

We had the original air fryers that used a few drops of oil. The World promised to become a paradise ... it was a disaster. The chips were nowhere near that deep fry satiety you always got. Modern day politics has taken society to the depths of despair - and this is our only saviour. The last bastion of feel good left, that only chips can fulfil. This is a dangerous piece of kit, within 19mins or so those chunky chips are ready, which means you could be eating a lot more chips than you used to. I'll be honest, I'm not fussed with the multitude of different foods it can handle - chips are the be all and end all for me - however, those frozen bakes were baked to perfection. No more emptying the oven of oil pan and baking trays for two bakes and a few chips that you had to individually flip, which all meant you didn't end up going to the bother of emptying the oven in the first place. A half-time shake is all you need for the chips, and, you can get away with not flipping the bake as it sit's on the rack. No more heating the oil to the right temperature, overcooking the chips because you were on the phone or getting spat at - this is the easy way. There are a lot of brands to choose from but Ninja really do make good quality products so it was the natural choice for me, all though you can buy cheaper ones. The copper finish looks a lot better than the standard silver one, already have enough silver/grey items around, definitely stands out amongst the other kitchen gadgets. If you have the space, the larger ones come with the rack. Ending up buying one for family, but they only have enough space for the smaller one - which doesn't have the rack option - glad I have the space, having now used both, the rack is definitely worth having. Chips underneath, bake on top - the biggest loser in all of this is probably Greggs ... except when you have to work away, but working from home, this is awesome. The contents of your freezer is going to change - that second bag of frozen chunky chips is going to evict something else :) HOWEVER, if there is one issue with this air fryer, it's the Temp & Time buttons. They are too close to the menu selection wheel and you have to press them with your finger sideways, you can't comfortably press them directly, as you can with the other ones. It is annoying.

I bought the Ninja Double Stack XL Air Fryer as a Christmas present for my mother, and it ended up being used heavily over the Christmas period, including for Christmas dinner itself. Build quality is excellent. It feels solid, well finished, and like a premium appliance rather than something flimsy or gimmicky. The vertical dual-drawer design works really well and saves counter space while still offering a lot of capacity. Space is a big highlight. It comfortably handled cooking multiple items at once, which was especially useful when preparing a large meal. Being able to run different settings in each drawer makes it far more flexible than a single-basket air fryer. The controls and presets are clear and easy to use, even for someone who isn’t particularly technical. Everything heats evenly, and results were consistently good across different foods. Overall, a high-quality, very practical air fryer that’s ideal for larger households or anyone who wants to cook more than one thing at a time. My mother loves it, and after seeing it used properly, it feels like a worthwhile upgrade over smaller models.
