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

We bought this 3 years ago and my only regret is not buying it sooner. Did they make this 25 years ago? Probably not. But it gets almost daily use, and it's amazingly versatile and high quality. It preheats amazingly fast, so much so that I rarely preheat at all. I just put the food in, set the time and temperature, and adjust the time an extra minute or two, depending on how high the temp is. Seriously, even for 400°, it'll get there in 2-3 minutes, so just adjust for that and put the food in. The door is so cool! It doesn't need two handles, which saves my limited counterspace and lets us use the countertop in front of the Ninja when we're not cooking. Ingenious design. I stopped buying expensive roast beef at the supermarket deli. I just buy a top round a/k/a "London Broil" and use the temperature probe with the preset settings. Just follow the manual and it will cook an average sized London Broil roast in 25-40 minutes, depending on your desired doneness. (And if you like medium rare roast beef, cook it to rare; it'll drift up to medium rare as it rests.) We use this almost daily for toast, English muffings, bagels, garlic bread, air frying seasoned curly fries, baking/broiling meats and fish. Reheating pizza. The list is endless. In the 3 years we've owned this, we probably only fire up our main oven 10% as often. The Ninja does just about everything. For the price, it's an amzing value and will be a great addition to any kitchen.

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!!

Upgraded from using a ninja flip for over five years, and I gotta say, I wish I'd switched sooner! I live in a small studio behind my dads house, and we never put in any major appliances, like stoves. So this is my alternate route for cooking dinner, reheating items, etc. And this one has really upped my cooking game! I can make more than one thing at a time and not have to worry about one item going cold while the other is still cooking. I love baking, and now i can do it all super easily at home. The bottom half is tall enough for muffin tins, single cake rounds, pies, and more! Word of caution, you may have to figure out how to adjust your cooking times for this appliance! Some things may need. A little more or less time than it normally would in a full size oven. I've had years of experience at this point figuring out how long for most items. You can find resources online as well to help guide you on small appliance cook times! Its super easy to figure out and use, and I hope it lasts me as long as my other Ninja has!

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.

So happy with my ninja! I've been enjoying my ninja for about 4 months now. It's so versatile and easy to use. You can make pretty much anything it. It bakes perfect cookies, cakes and muffins on the top. The toaster setting on the top is what I use to make a grill cheese sandwich in minutes. The larger bottom does great roasted vegetables and proteins. Of course the air fryer setting is excellent for all your fryer foods. Pizza comes out so perfect with a crispy crust! It fits perfectly on my counter, just under my microwave. I like to warm my plates by just setting them on the top while cooking a meal. I highly recommend buying oven liners for easy clean up and square silicone mats for the oven pans to keep them looking new for a long time.

I got this double oven 3 years ago and it has almost completely replaced my oven use. There’s only two of us in my household, so it’s enough space for all of our meals. We only use the big oven when we’re having guests, though my oven has been down for the last few months, so we’ve had to use the Ninja double oven even with guests (we just cook in smaller batches). The convection setting is my fave because it cooks evenly and gives food a nice crispiness. Second to that is the air fryer feature, which is use mostly for reheating food, but also for fries. I use the bake option on the top oven for salmon. And we use the broil feature for steaks. If Ninja were to make a full size oven, I’m pretty sure I would buy it based on my experience with this double oven. I didn’t include a photo because I’ve really put this machine through its paces and it’s not as shiny as when I first got it, but it still works really well! I highly recommend!

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.

WOW! I love this thing!!!! Where have you been all my life! Great features easy to use, prefect toast and fast! Highly recommend would buy again!

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.

Lo compré el año pasado, y ya llevo meses usándolo. Funciona muy bien, no he tenido ningún inconveniente con él, he hecho comida, pasteles, repostería en él y me encanta. ❤️

Hasta el momento esta funcuionando perfectamente despues de todo un año, y se usa diario, calienta rapido y uniformemente, con muchas opciones para una mayor flexibilidad

Es un horno muy útil. Lo uso para todo para hacer cualquier proteína como pollo, carne o pescados.

I can’t live without this Ninja product. I use it all the time and it’s replaced so many small kitchen appliances (air fryer, dehydrator) I bake and cook in it all the time. I very rarely use my regular oven now (we are a household of two). The only downside is it takes a lot of counter space and is heavy so a pain if you want to put away after use. It also does not have a rotisserie and likely the bottom oven would be too small to rotisserie a chicken.
