Customer Ratings & Reviews

Easy to use and great results. A few trial and errors (toasting times, etc.) will get you going in the right direction and you’ll love it. The air fryer function works excellent I am most pleased with the new Air Fry oven. Although I am still experimenting, as I have not had it very long, I am happy with the food it has produced. Every new piece of equipment has a learning curve, but this has been an easy one. The recipes I cooked in my old air fryer oven work just as well in this one. The more I use the Ninja Double Oven, the more I like it.

Definitely would only want the version with the smart thermometer. You have to open both doors to access the bottom, so it wouldn't be great to have to keep opening both doors to check the temperature on the bottom. Used the thermometer once so far and it cooked a tri tip perfectly. For the price it would be nice to have two crumb trays and the roast pan. Can take a minute to figure out the smart finish, the door won't lay flat, the light won't stay on and the top burns things pretty easily, but overall a decent purchase so far.

I love having options to cook, so this in addition to my normal oven is perfect for my family. It air fries very well, and can be a toaster replacement as well as a convection oven. So I could not really rate it any better. I've used many small toaster style ovens, and this one does the best I've ever had by far!

We had an air fryer and convection oven , and i must say this single oven is by far much better , does more than the other 2 together

We wanted an air fryer, saw this on sale for deal of the day and decided to replace our old toaster oven with an all in one. Works great, no more burnt toast!

A kitchen is not complete without this amazing oven/air fryer. The separate ovens make things easier and faster, specially with the smartcook feature. Higly recommended!

I honestly dont think ill be useing my normal gas range ever again (except for turkey day lol) othercthe that this thing does it all for me. The built in thermometer that stays in while cooking is the best part. Just season meat stick in thermometer select how well you want your meat cooked an BAM its done perfectly the way you want it.

Bought to have as main toaster and have other features but honestly toasting feature is just never the same each time you go to toast something (even if using same options). But otherwise works great, would recommend but not as a main toaster

Amazing. Easy to clean. Cooks everything so that it tastes as fresh and flavorful as can be. Reheat leftovers and they taste like they’re fresh out of the oven. Cook multiple sides. Cook sides and an entree all at once. Such a standout appliance truly.

The product is easy and efficient. I would recommend my Ninja DCT 451.

Great product is used for multiple uses. Love having this when cooking or air frying. I can’t wait to use it for most of my meals on a daily basis.

We highly recommend for efficiency, convenience and quality. The food always cooks perfect.

Ive found myself collecting Ninja products over the year. Their products speak for themselves and has kept me a customer. As always no complaints here for Ninja!

Works great does everything I need fits on my counter top a little big but works great

best oven ever !! works as advertised !! easy way to cook multiple items together !!

I didn't expect to be impressed by any new oven technologies, but here we are! This Ninja double-oven is a game-changer! Setup =============== Be prepared for a large box to be delivered! You can see in the picture, that this Ninja double-oven really dwarfs my Breville smart oven. We've used that little guy for years but the convection fan is broken (common issue with that model) so it's "just" a normal oven, though it's a good one! Unboxing is a non-event, but it's nice to see all the stuff you get! Obviously there's the oven, but you'll get trays, air frying trays, a crumb-catching tray, and thermometer. Place this on your counter, plug it in, and you're pretty much good to go! The instruction manual is worth reading for some unique things like Smart Finish which will ensure both ovens finish at the same time and a chart of cook times for various foods and methods like dehydrating fruits/vegetables, etc. Note - the manual recommends adding cook time to both ovens if you're using them both simultaneously. I was confused by this because when you set a time/temperature, isn't that enough? It turns out that things work out pretty well! Usage/Testing =================== We used our little old Breville every day so we had a good idea of what to expect out of an oven, but this double-oven really impressed us! We first started with simple things like bagels on top and some sweet potato fries/nuggets on the bottom. As you can imagine, these have wildly different cooking times and temperatures, but the Ninja nailed it! The top oven is perfect for flat foods like bagels and pizzas and you still have another whole oven to use for whatever! Note - the bottom oven/fan does get loud when it's air frying/convection cooking but it's not a problem, just louder than our old one. Next, we tried spanokopita on top and some nuggets/zucchini on the bottom. We noted two things: 1 - We probably should have turned the spanokopita in the middle of cooking (our fault since the manual recommends turning the food during cooking) since one half was clearly cooked more than the other. 2 - Definitely add a few more minutes of cooking time when using both simultaneously (easy to do by selecting the top/bottom oven and turning the knob). Since then, we've done simple reheating, toasting flautas, and even air-frying mackerel and everything turned out great! Conclusion ================ Yes, it's a bit taller but if you can fit it on your counter, it's a great double-oven! If you find yourself constantly preparing two or more things that you used to have to cook one after the other, definitely look into this Ninja double-oven! Yes, the fan is a bit louder than our old Breville, but buttons/knobs make the Ninja super-easy to use and the fact that you can cook two wildly different things at the same time can help you get your meals done faster! Taking advantage of the Smart Finish can make sure that everything's done at the same time so you don't end up with cold fries by the time your main protein is ready! Again - I didn't expect to be impressed with a relatively simple device like an oven, but the Ninja 12-in-1 Smart Double Oven is a game-changer! It has clearly defeated our old Breville and will be our daily go-to appliance!

THIS…. Is the Ninja 12-in-1 Smart Double oven, not to be mixed up with any other 11,12,13,14 in one’s from ninja because this is THE 12 in 1 to have! To start, it is quite simply an eye catcher in your kitchen… and not just because it is rather large, but because the stainless steel and the interface are so clean and premium looking that you can’t help but look at it with googly eyes. It uses buttons and nobs to interface, so you don’t have to worry about a greasy touch screen or some odd app to control your oven. With the premise being laid out, lets take a deeper look at the Ninja 12-in-1 Smart Double oven! Smart vs Non-Smart =================== Lets start with some confusion - This 12-in-1 Double oven comes in two ‘trims’ - One ‘Smart’ and one that isn’t ‘Smart’.... So what does that mean if they both have ‘smart features? The ‘smart’ double oven comes with the temperature probe so you can use the smart finish, and it only cost $20 more at MSRP which is an absolute no brainer as the smart finish tech alone is worth $20 before being able to see the temp of your turkey, chicken, pork…etc while cooking without having to open the door (on both the top and bottom) to test the temp of your meat while it is cooking and letting alllllllll that heat out - So while you can get it without the temp probe, I highly suggest you burn that extra $20! Setup =================== The hardest part about setting this thing up is making sure you have clearance for it, and mind you the door doesn't go ‘flat’ due to the handle… but it gets close enough that it wasn't a hassle or second thought for me with 5lbs of chicken in and out of the bottom. There isn’t any app to download or weird setup process - if you need to use the temp probe you plug it in and follow the directions… if not… you just put in your time and temp! Setup is a breeze, and the ninja comes with everything you need to bake, broil and air fry. Honestly was standing there with my Fiancé after taking it out of the box in that ‘now what’ phase as it really is just a plug and go setup, NICE! Function =================== First, lets go over exactly what the ‘12’ is, in this 12-in-one: TOP OVEN— Bake, broil, reheat, keep warm, bagel, and toast. BOTTOM OVEN— Air fry, convection bake, pizza, air roast, whole roast, and dehydrate. This is obviously more than enough function for just about everyone, the only thing I wish it had was air fry on the top but… I have never ran into something where I needed to air fry two things at once and couldn’t in the bottom, or rapid bake in the top. NOTE - You will need to preheat this oven just like you do with all other ovens, however, this oven preheats insanely fast?! It is always done preheating in 5 minutes or less and usually beats me before I am done prepping my food. What you Should know =================== -You cannot air fry on the top oven -You can open the top without opening the bottom, but if you open the bottom, you have to open the top. -You CANNOT remove the middle divider to expand your space, it is structural. -it comes with ONE grease catch for air frying on the bottom, but if you are messy (all fingers pointed at me here), you might want to buy another for the top. - The directions that come with this oven are great, and if you take the time to sift through the quick start guide, teaches you everything you need to know in a multistep format that just WORKS! Things I really liked =================== -I really enjoyed that there was two rack positions in the bottom oven, so that if you have to small items you can really cook 3 things at once using the top and bottom - and then seal out the smell of one of them if you are worried (ie. nuggets and fries on the bottom, cookies on top). -The lights aren’t just always on, you turn them on and they elegantly swoosh on and then have a self timer to turn back off. -It isn’t really that loud to be honest! For sure quieter than a microwave and quiet enough to have a conversation next to it as well. Things I didn’t like =================== -I wish it came with a crumb catcher for the top as well, I understand the top should be cleaner, but something there to catch in case it makes a mess would be nice. -I wish it had an app at least to send me a notification when it is done, this replaced my tovala, and that sent me a notification when my food was done which is always nice so I can leave the kitchen or not have to be an arms length away. Is the Smart Seal Legit? =================== Yes! Cookies on top, chicken on the bottom and a Lady that would sniff a molecule of one on the other and it passed! Cookies were cookies, and the chicken was chicken! My Fiancé is insanely picky when it comes to cross contamination, and this genuinely worked perfectly! I love this feature and makes me want to use it more knowing I don’t have to worry about the mixing of scents and tastes. Conclusion =================== Let me say one thing before I wrap this up - I think that Ninja goes crazy with their marketing considering this is a 12 in one being advertised to feed x amount of people with wings and pizza in x amount of time. This can do that, it can do 12 things also, but it cannot do 12 DIFFERENT things - the 12 in one derives from 6 functions from the top and 6 functions from the bottom to really be a 12-in-2 which is fine… I just wish it was presented that way. ANYWAYS… This is by far the best countertop appliance I have used, and I have used several brands of countertop ovens and air fryers. While this one is expensive considering it is $350 MSRP, it is also an investment in how well and quick you want to cook your food. This is an easy guilt free purchase that will level up your kitchen, and I have enjoyed my time with it… even just looking at it! Ninja has killed it with this product and again reminded us why they are the pinnacle of countertop appliances yet again! As always, BestBuy has excellent customer service and return policy, so you never have to worry about buying a product that you don’t like… so why not test it out?! What Comes in the box =================== Oven 2 Sheet Pans 2 Wire Racks Wire Air Fry Basket Crumb Tray (one) Thermometer (magnetic to side of machine) Quick Start Guide/ Manual Power cord is affixed to the oven and cannot be removed

This is a cool concept for a busy family with low time after work/school for dinner. I was excited to get this as we often have a wait to use the oven. Unboxing this was easy. It included the oven and several trays for all of the needed functions since due to the space your pans would not fit well. One thing I was looking for was a smart app thinking the smart name meant an app of some sort. Well, there was no app. Otherwise, it was up and running in 10 min. I proceeded to cook some pizzas and the preheating was very fast unlike a traditional oven. I did like that but did not feel it cooked them faster. Also, when your used to an oven where you preheat this works a little different. Since the preheat is fast. You basically put the food in and set the temp and time. When you hit start part of your time is the preheat but it is so fast it does not take away from the cooking time. I still found the food cooked. I just wish this had a way to preheat then a beep or something to start the timer. I also cooked some cookies in the top tray and some pizza rolls on the bottom. They were both cooked well and did not smell or taste like they were baked together. I unfortunately did not have anything to dehydrate or air fry. I also do wish it was able to perform a microwave function also at a lower temp. I personally nuke a frozen meal and frozen veggies and this was not able to do that without burning them. Maybe that could be the 13th feature in a gen 2? The downsides are the size as it is big on the counter, so we felt like it took a lot of our space on the counter. Also, the top does get hot. It does have a symbol, but it is small and can easily be overlooked. I wish there was some better shielding or something to make it more obvious for the younger kids in the family as I would not want them to get burnt. In summary this device is as advertised, and I feel like for the family that cooks many things at once or wants to save energy vs the traditional oven. Then this is a great addition to the kitchen. I just wish there was a smaller model as it takes a lot of space on the counter.

As an avid home cook that routinely cooks for a household of 8, I was blown away by the Ninja 12-in-1 Smart Double Oven. It truly lives up to its advertising claims and offers numerous time-saving features that make cooking so much better I can’t even say it in words. The dual oven setup is a game-changer for busy households, allowing you to cook two separate dishes at different temperatures simultaneously which you know is a thing if you have a multi child household. Plus, the flavor seal technology keeps distinct aromas from mixing which again is a huge thing for my kids if there’s any “wrong” smell they won’t touch the food I spend hours on which is extremely frustrating. The Flex door is also a helpful feature, allowing you to access one dish without disrupting the other by letting the heat out. Features like this just keep coming and coming and make everything that you have to break your brain on just work, and EASY! One thing I was pleasantly surprised by was how quickly the oven preheats. I often times avoided making things in my gas oven because it takes FOREVER to heat up so this is a welcome change and in fact a game changer for my impatience when I’m trying to cook for my 6 kids. One thing you should keep in mind is this unit is fairly large but not more so than a large microwave (see my photos to compare to an LG one I have which matches the stainless perfectly). So make sure to check dimensions beforehand to make sure you have enough counter space or if you don’t that you make some because this thing is worth its weight in gold. The air fryer option was also great as we somehow have never had an air fryer and just a couple older convection ovens which are aged at this point but delivering perfectly crispy results without overcooking or burning is always remarkable. If you haven’t had the pleasure of using an air fryer just note it makes frozen things as if you bought them from the drive through and if you have kids you know this is key to keeping them happy! Despite the initial investment, the Ninja Smart Double Oven includes everything you need to cook, bake, air fry, and do anything you can do but like a pro because the thing just works. The smart leave-in thermometer is a particularly helpful accessory, allowing you to monitor the temperature of your food without having to open the oven and let out heat since it snakes through the doors which is once again game changing as some food boxes say get internal temp to X degrees rather then a cook time and you always have to pull it out to check and loose all your heat in the process. Overall, I highly recommend this beast of a kitchen appliance to anyone who values efficiency in the kitchen and wants to simplify their cooking process without sacrificing quality. It's truly a game-changer for anyone who loves to cook at home.

I cannot stress how cool this 12-in-1 from Ninja is. Coming from someone who does not cook very often, the convenience and stress free setup is an absolute win. It has two ovens, a top and bottom, and you can set different options for each individually (which is so cool!). The bottom is used to air fry (the top oven you cannot air fry, but that is not an issue). The top you can bake, toast, reheat, and broil and the bottom you can air fry, roast, dehydrate, convention bake, and air roast. You can open the top oven without opening the bottom. There is a convenient button on the top handle you can push to just open the top door. The oven also comes with a good amount of accessories which include two sheet pans, two wire racks, Air fry basketCrumb tray, 15-recipe guide, and a Foodi Smart Thermometer. The Thermometer allows you to verify the temperature of what you are cooking without having to open the doors, thus keeping the heat in and allowing you to only open the door when you are ready to enjoy what you are cooking! Another really cool part of this design in the Smart Seal, which seals the top from the bottom so there is no cross contamination. This means you chicken does not taste like fish and via versa (assuming you are cooking both at the same time). Overall, I am thoroughly pleased with this 12-in-1 from Ninja. So much so that I might pick up cooking. The setup is super simple, the design in elegant and solid, and the functionality is on point. You cannot go wrong with this 12-in-1 oven from Ninja.
