Meet the Ninja Double Oven, the countertop oven that unlocks the power of two ovens in the counter space of one. Only Ninja has the FlexDoor that creates 2 separate ovens so you can cook 2 meals, 2 ways at different temperatures and cooking times. Use just the Top Rapid Oven for quick snacks, sides, and sheet pan meals—or the Bottom Convection & Air Fry Oven for larger roasts, bakes, or air frying up to 6 lbs of wings. You can also sync both independent ovens to cook a full course meal that finishes cooking at the same time with Smart Finish technology. While your meal cooks, FlavorSeal technology prevents flavor crossover between ovens. The Smart Cook System precisely monitors temperatures with the leave-in thermometer, so you don’t have to. Two oven cavities in one eliminate back-to-back cooking for 65% faster meal-making than your traditional oven so you can put your wall oven out of business. Plus, this countertop dual oven features 12 cooking functions for the ultimate versatility.
FLEXDOOR: Creates two separate ovens. Access just the top for quick meals and snacks, or open the full door so you can cook 2 meals, 2 ways on the top and bottom.

The best toaster oven I’ve ever had!
This toaster oven is the absolute best! It’s big, looks beautiful, and cooks and or reheats everything perfectly. It comes with two 12 x 12 trays that you can fit a lot of food on. I made bruschetta with baguettes and each tray held 30 pieces. It also has an air fryer tray that you can use for cooking or reheating. Everything comes out perfectly crispy. It’s very easy to use and I love that I can run both sections at once on different setting. I’m so happy with this purchase!

Great little oven plus more!
My big oven has not worked for years & I had an Oster countertop oven that worked fine however I had separate air fryer, oven. Dehydrator & the Oster broiler wasn’t great. This double oven is really cool, I am loving the features & am about ready to give up the appliances it is replacing! We air roaster a pork loin on the first use, using the attached thermometer & it was absolutely perfect! With no monitoring or attention from me which is great.The only thing I would change is adding the air fry/roast option for the top oven. One night I wanted to air roast some meat in the bottom & wanted to air fry the veggies in the top but there’s no air fry in the top. For that reason I’m keeping my air fryer but I do love this oven. Also they could have included 2 crumb trays so the (included) one doesn’t have to be moved to whichever oven that is being used.I bought an extra crumb tray from Ninja & the bamboo cutting board that fits on top, from Amazon & feel I have the best setup ever! Performance is perfect & also it cooks or heats, whatever, very fast so it saves time & also less heat in the kitchen. This is a really smart product & you will like it!

The counter top oven I have been waiting for!
Since my husband and I are the only two home, firing up the big oven all the time seems a waste – plus it heats up the kitchen which is not fun in summer. An added catch is that we don’t eat the same. I don’t eat meat (I will eat fish) and he hates fish but loves a good roasted chop. Anyone who doesn’t care for fish is always wary of cooking it together with meat – it does tend to infiltrate!I have tried many counter top ovens. Some didn’t work AT ALL: I couldn’t get the touch panel on the Oster Convection Oven to work without practically breaking a finger; the Elite Gourmet ETO-4510M got WAY too hot (inside and out) and was complex because it expected you to manually synch the top and bottom heat source (which were both in the same oven, unlike this one) and the french doors were a definite burn hazard; the Hauswirt 26Qt Air Fryer Convection Oven Rotisserie was also too small and got dangerously hot on the outside. The Breville Smart Oven Pro Toaster Oven is a great little oven – I have actually had 3 over the years – but the big drawback is only one shelf. I once ordered an extra shelf so I could put two things in at once, but there really wasn’t room and if the two things needed different temps there was too much math involved. Also, the fish/meat thing.The Ninja DCT451 is a superb little oven. I love it and so far can’t find anything about it I don’t like. What I do like…- top and bottom operate separately but can also be synched- the top is small (slim really) but easily accommodates a pizza- the door can be opened just for the top, or for both- each oven has separate controls, making it easy to set each one for different things- so far it seems to cook (time/temp) per instructions for the item with no need to adjust- the functions of each oven are easy to select (toast, bake, convection etc)- there is an inside light (a really nice feature)- the outside doesn’t get too hot – just mildy warm- the size is great for the capacity inside, fits nicely on my counter- it has plenty of pans – 3 shelves, two roasting pans and an air fry mesh thing.- the pans are very heavy/good quality (not flimsy – even the Breville was guilty of that)- it says hello and goodbye 😃A great purchase – I am really glad I spent a bit extra. Its is well worth it.

Easy to use, seemingly easy to clean, missing some finishing touches
I’ve had this oven/air fryer for less than a week, so still getting used to it. It looks nice, despite being rather big. Controls are easy to use, but a little different than a standard toaster oven’s. Today I made bacon in the air fryer basket and was amazed how easy the basket cleaned up, especially considering it isn’t the non-stick basket. The air fryer has done frozen chicken nuggets covered in BBQ sauce well, and the top has done a variety of reheating, cooking, and toasting–all perfectly fine, no complaints. There are some design touches I wish this double oven had…1. I feel like there should be 2 separate doors, instead of the integrated door that can just be opened at the top for the top oven, or all the way for both. If I’m cooking something in the top, but just need to adjust something in the bottom, then I’m forced to still open the top oven.2. The handle for the oven is about 3 inches high, so unless you are opening this on a counter where that handle goes off the edge of the counter, it doesn’t allow you to open it all the way and be able to pull the bottom oven grate out all the way. I have put the oven up on some slider feet to give the base some height, but it’s still not quite enough to balance the height of that handle when open. This just increases the likelihood of burning yourself and/or having trouble pulling out what you need in the bottom oven.3. This double oven is not wide enough to hold a standard size (12″) round pizza pan. What? That seems really silly. The internal oven width is just about 12.5″ but a standard 12″ round pizza pan is actually closer to 13″ because there is an edge around the pan. The internal width of the oven is just about a quarter of an inch too narrow. Additionally, the internal width of the included square baking pans is not big enough for a full 12″ round pizza either. So don’t expect to cook a pizza bigger than 10″-11″ with this oven.4. My previous toaster oven had a magnet on the door that helped pull the oven grate out about an inch when opening the door. This was very very helpful and this oven does not have that feature. I really really miss it. Additionally, there was a little bracket inside my old toaster oven that prevented you from accidentally pulling the grates out too far and having them fall out. This would seem a pretty highly desired safety feature and I’m not sure why it wasn’t included with this double oven.5. Only one crumb tray for the bottom was supplied. I would like 2 for both oven compartments. You can buy another on the Ninja site for $10.All around, a good oven. I wouldn’t pay $350 for it, but I got mine on a lightning deal for about $250. I think it was worth it. I’m looking forward to trying more things in the air fryer.

This toaster-oven-air fryer is really nice. I had a few other oven like this from other manufacturers and none of them produced the quality of toast this one is producing! The dual oven setting is really great and make usage is perfect. The air fryer is big and convenient and produce crispy food. The warmup is pretty fast. Operating the oven is a little bit confusing at first but once you get the hang of it, it is pretty straightforward.The cons :It could be a little larger as a 13 inches pizza sheet pan won’t fit in. Also, it is alittle noisy compared to others I had. The lower oven could have 2 more height setting for the rack for better convenience.So I really recommend this oven, the best I’ve owned up to now.

Excelente!! Mejor inversión no pude hacer, sin duda lo recomiendo, ha hecho más fácil la elaboración de las comidas en casa, al punto que mi esposo está feliz de usarlo también. Permite que los platillos se realicen más rápido de lo que solían ser, además de que, hemos aprendido a realizar platillos nuevos, uno de nuestros preferidos es el pollo rostizado, mismo que queda listo para comer en un tiempo de 40 minutos. Por otra parte, ya no es necesario utilizar aceite al guisar, y, si se requiere es mínimo lo que se utiliza, como ejemplo, las milanesas que quedan perfectas y solo requieren el mínimo de aceite.
