Ninja DCT451 12-in-1 Smart Double Oven with FlexDoor, Thermometer, FlavorSeal, Smart Finish, Rapid Top Convection and Air Fry Bottom , Stainless Steel

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!

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!

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.

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.

I’ve been using the Ninja DCT451 Double Oven for a little while now, and this thing has completely changed the way I cook. I honestly didn’t expect it to replace my full-size oven as much as it has, but it heats up so fast and cooks so evenly that I end up using it for almost everything. The FlexDoor design is genius because I can open just the top section without releasing all the heat from the bottom, and it makes it way easier when I’m multitasking. The Smart Finish feature also works surprisingly well. I can put different foods in the top and bottom and have them finish at the exact same time, which is perfect for making full meals without babysitting anything. The top oven runs like a rapid convection setup, and it gets food crispy without drying it out. The bottom air fryer section is powerful, cooks quickly, and honestly does a better job than some standalone air fryers I’ve owned. The built-in thermometer has been super accurate so far, and it takes all the guesswork out of cooking meats. I’ve tried chicken breasts, steaks, salmon, and even a whole roast, and everything has come out cooked perfectly without me constantly checking on it. Clean-up is easy, the stainless steel looks great on the counter, and it doesn’t take up anywhere near as much space as I expected for something that basically acts like two ovens in one. The only thing I’d mention is that it cooks fast, so you have to get used to shorter cook times if you’re coming from a traditional oven. Once you adjust, it’s honestly a huge upgrade. This oven has become one of my favorite kitchen appliances, and I use it every single day. If you cook often or just want something fast, versatile, and reliable, this is absolutely worth getting.

I absolutely love this toaster oven/air fryer! It does so many things! They give you a recipe/idea’s book which is very helpful. It cooks very well regardless whether you’re using the top or bottom. It preheats quickly, although I rarely preheat. With only a two person house this cooks the perfect amount of food without having to heat up a big oven! Which is important in Arizona!

My daughter convinced me to give Ninja brand a try (an old Breville customer) after my toaster oven just wore out. I was hesitant but she uses all Ninja items so I gave this a try. I absolutely love the 2 oven feature & the ability to postpone one or the other oven so that it goes on to finish both oven cooking times at the same time for serving. What an incredible idea. You prepare & set the timer for each oven's item, then if you want them both to finish cooking at the same time but one has a shorter/longer cooking time, you can set both up with temps/times & the select to have them complete cooking together. The oven with the shorter cooking time waits to turn on until it matches the ending time of the other. Many great meal suggestions for preparing entire meals using both ovens. I have only baked and air fryed in each so far so I can't comment on the eveness of toasting bread but I did find on one pre-packaged item I baked that the temp on the item package seemed a little too high & it browned more than I'd wanted but that isn't the oven's problem. The directions were for a regular oven so I think I'll watch to adjust somewhat for a toaster oven. I am 100% happy with the looks, style & performance of this combination and although it's large, it fits perfectly next to my stove top and is used daily. Ninja really hit home with this conveneint double oven. Love it.

We've had a couple of air fryers, the basket kind that took up too much space, for the limited things that it would do, and the toaster oven kind from a brand that is outfront with certain pot that they make... This toaster oven with its two separate ovens which seems crazy but it's fantastic, does not use convection in the toasting top part of the oven. Instead of desiccating toast with hot convection waves, this actually toasts like real toast, you can put it on the rack or, I prefer oven toast on a small cooking sheet pan. This is like the toast I grew up with the toast that your grandmother or mother made in the oven! You can put butter on it and it comes out crunchy, not like a piece of sandpaper, as the toast from a convection oven does. That alone makes this thing worth it, however it has many other features that are user friendly, customizable, and helpful. So if you really do want to dry something out or cook it fast, the bottom of the will do that for you, and the air fry for french fries and fish sticks and chicken tenders, all of those things is fantastic and efficient and quick for an individual or a family. In fact the toast makes up pretty quick too because the top oven is very small so do not walk away. I've been accustomed to making toast for almost 4 minutes -- a now 2 minutes or so, you've got a nice medium brown piece of crunchy toast. Yes I'm obsessed with the toast! I really missed oven-type toast. It has a sweet little dinging tone for ending and selection that is not annoying like some of these models. Don't know if you can turn it off, I wouldn't want to because it's just the cutest little sound and is helpful. You have a dedicated instant on/off button. The knob selector that selects toast color and number or whatever function you need also punches in to lock that in. Once you are cooking, you can punch it to stop turn heat source immediately. There's also a button for a light that lights up both ovens, that stays on a fairly long time maybe 30 seconds. One tap and it's right back on again. It's slightly bigger than the "IP" brand that we had before, chunky little squareish thing. But it is much less wide than most of the multi-featured models out there, and of course it needs to be pulled out a little bit for hot air frying, cuz there's a vent on the back. The glass does get hot on the front, as of course it should. The two doors on this model are fantastic. You don't have to move stuff out of the way underneath, if your coffee is waiting for your toast to be done. You punch in the top button and open just the top shallow toaster oven, so there is no need to open all of the door that comes all the way down to the countertop. When you're making toast or Pop-Tarts or bagels or whatever, you only need open/close the top door. I love that little top flip door. You don't have a big hot oven spreading heat into the kitchen when you flip up in that little door. In fact both of them are well insulated even though the glass gets hot it does not spread heat into the room like our other brand. So you don't feel heat all the way from the countertop to the dining table as we had before. And it's quiet, so so quiet compared to the screaming multi-function oven we had before that sounded like a C-130 landing for 30 minutes. My one complaint and this is true of most appliances, when you have to burn and break in the new appliance. I thought I was going to leave the house. It is that disgusting and dizzying and miserable. It's much like self-cleaning your regular oven, it is smelly and sickening. There's just no way around it though. It has to be done before use, but I would recommend plugging it into the garage or even on a patio or something because inside the kitchen the smell of the burning off of the factory, really permeated the atmosphere in a miserable way. Turn your air purifiers way up, and the vent fan on your stove! Other than that it's a fantastic little appliance if you don't need to cook huge things. You could probably just live with this as your one and only oven. I'm not sure if you can bake cakes in it as you could with our other one, but I bake cakes in my big range anyway. I believe you can cook a whole chicken in this though. We use ours for toast and Pop-Tarts and bagels and warming up things reheating things, re-crisping things. There are a lot of things we microwave for a minute or so and then crisp up in this kind of oven and this does all of that very well. Another issue is that I toast buttered flour tortillas quite often, and I have burned up a toaster oven when the tortilla puffed up and touched the heating element. I heated up frozen flour tortillas, handmade by the way, so they are extra thick -- and I stood by and did not take my eyes off of the tortillas that were on a toaster oven size baking pan. I don't know if they just happened to be not puffy or if the freezing protected them from puffing up, but I successfully toasted some flour tortillas that were delicious. If you're going to do that, as with toast or bagel don't walk away, keep your eyes on that little top oven because it cooks really fast. So I'm crossing my fingers that I will have future successful toastings of flour tortillas. I really highly highly recommend this, especially if toasting bread is something that you do on a regular basis because the other air fryer / convection ovens do not have this extra little separate oven that is just a regular toaster oven. This makes all the difference. I've been suffering with desiccated bread from hot convection wind for a couple of years now, and it was such bliss to eat a regular piece of toast again that was cooked very quickly without having to heat up my huge oven that would have taken 20 minutes probably. Butter up a piece of bread throw it in on a little baking sheet, and you have some darn good crunchy medium toast in under 3 minutes, anyway. Pick your toast shade! Buy this thing you'll love it for the other functions as well. I first purchased an air fryer after having my gallbladder removed so I could enjoy crispy things without drowning them in oil. It's been 10 years, and we use an air fryer several times a week. High power 1800w so don't plug it in at the same time you're using another powerful appliance. This one shares a wall outlet with a coffee maker and can opener, is all. Worth every penny!!
