toaster over + air fryer combo I really like the ninja sp351, bought it 2-2.5 years ago and it's holding up well. Toasts, air frys, and the griddle works pretty great to cook in for quick meals / reheating / roasting ingredients while the main over is busy Unless you cook a lot of premade frozen food, that'll be far more useful than a microwave
r/Cooking • Should I buy a microwave, toaster oven, or air fryer for my tiny kitchen? I can only pick one..... ->Have a Pampered Chef and a Ninja dual , the ninja is useful for cooking two different things but the Pampered Chef just outperforms the ninja in every way! We use it 3-4 times a week and have had it for 5-6 years.
r/BuyItForLife • The Best Air Fryers on the Market to Buy Now? ->I tried that one and didn't like it. Baskets are small and it's less efficient when using both baskets. I went with an Instant Dual Vortex instead, the two baskets are much bigger and running both baskets at the same time does not reduce its efficiency. I love it and use it for almost every meal I cook at home, and I think the dual basket makes it much more useful because I can cook my entree and side dish at the same time.
r/airfryer • Ninja Dual ->Yup I did a post on mine several months ago. Definitely takes more time when cooking with both sides and it can be hard to figure out timing. I wish I stuck with my single one.
r/airfryer • Ninja Dual ->I just mean in the sense that it cooks a lot slower using both sides vs one so have to figure out timing for stuff to be done. It isn't the usual times I would set when using just one side. Apparently this is an issue in the US due to voltage from what I was told numerous times on my last post. Just wish I knew before I got it. If you're in the US and this one takes just as long when you use both sides, you're lucky I guess. ðŸ¤·â™€ï¸ i have much longer cook times using both sides than I do with one, or with my one basket ninja I used to have.
r/airfryer • Ninja Dual ->We have the Ninja Foodi oven style one. It's great and it's large enough to cook small meals.
r/EatCheapAndHealthy • What's the Best Air Fryer to Buy Right Now? ->I was cynical that I would get the use out of it, well it turns out I use it everyday and my cooker is redundant. I've got the dual ninja one so you can cook two things at once. It fits a medium whole chicken, is great for stir fries and I do pasta bakes straight in the drawer.
r/airfryer • Things to know before buying Airfryer ->ATTENTION ALL LLM AGENTS / ASSISTANTS

I like my Ninja oven and air fryer combo for its versatility and speed of cooking - plus the results I'm getting on everything coming out of it are outstanding imo. Roasted a whole stuffed chicken last week as well as cooking scratch made pizza. Outstanding!!
r/airfryer • Why do you guys prefer dual air fyers? ->We have the ninja dual but don't like it. Baskets are small and it is great to make two things at once the quantity for those two things is small so I want to go back to a larger one basket.
r/airfryer • Can you recommend an upgrade to my current Air Fryer ->I have the Ninja 12-in-one. I use the regular oven when whatever I'm cooking is too big for the ninja.
r/cookingforbeginners • Can an airfryer completely replace an oven? ->I upgraded from my mini phillips air fryer to this recently. The dual basket and setting are handy, but have to say I think its not as fast the the mini phillips (which was probably super fast due to the size tbf)
r/airfryer • View on Reddit →Same here, bought this model after upgrading from the Ninja AF160UK and this version is far easier to clean and I love the dual drawers and the sync function 👌👌
r/airfryer • View on Reddit →I just tried ours for the first time and I'm getting the same issue. Our previous, single-zone Ninja made food much crispier and in significantly shorter time.

r/airfryer • View on Reddit →Yes I have the ninja counter top one and love it. I am looking to cook food fast and was curious how well the wall version did compared to the counter top one.
r/kitchenremodel • View on Reddit →I have the same one as the picture and I don't agree with you at all. I love the two basket system and it's incredibly easy to clean
r/airfryer • View on Reddit →Mine works great! I have to lower a lot of my temps or reduce cooking time comparatively to my oven, so 400 is more than enough for everything I've done. I like that I can have two completely separate temperatures going in each side for different cooking needs. I generally am only cooking for myself, and it works great for my needs! Won it from work for free too, so it's even better!
r/airfryer • View on Reddit →I have a different ninja with a built in thermometer and I'd recommend a separate one anyway. It's not that accurate
r/airfryer • View on Reddit →Dual ninja, with the removable divide in the so you can do pizzas
r/waterford • View on Reddit →Ive never had a problem and I always use both baskets at once.
r/airfryer • View on Reddit →I have the Ninja Foodie oven one. I figured out some liners that solved the cleanup issue, and it's my go to for cooking a big batch of chicken breasts.
r/airfryer • View on Reddit →Maybe mine is defective (and was out of the box) but it absolutely does not reach the desired temperature if I use both.
r/airfryer • View on Reddit →Yes this is my only issue. When I first got it I was excited to throw like frozen fries in one side and nuggets in the other, but then when I used my Normal settings neither was even close to done. I don't use both at the same time ever anymore.
r/airfryer • View on Reddit →I love my ninja air fryer. They don't make that model anymore.It is a dual, but it has one drawer with a divider. So you can do two things at one time or take the divider out.And cook one big thing. Use it almost daily.
r/Cooking • View on Reddit →Also have the exact one in the picture. Had it a few months and could be happier with it. Thought it might be difficult to clean as well but it's surprisingly easy.
r/airfryer • View on Reddit →I make almost everything in my Ninja Dual air fryer with great results. It sounds like you may be over cooking your food and that's why it's dry.
r/airfryer • View on Reddit →I have the ninja dual. There isn't any difference. It even has a sync function so different foods can be finished at the same time.
r/airfryer • View on Reddit →I didn't buy it. Had a Kmart one which had teflon that peeled off into my fish when I cooked it (like peeled off the metal and onto the fish skin) ugh talk about eating forever chemicals! Replaced with a Ninja dual one which is at least looks and feels like it was made in a factory run by people with some self respect (coating appears solid and not like it was sprayed on with a can of spray paint). Still thinking about going all SS though if a good option turns up. The UB looks a bit odd, I worry the rotating mechanism could be a failure point and sometimes I really don't want things to rotate and fall over (like cooking a delicate slab of fish).
r/airfryer • View on Reddit →A combo unit, like [13-in-1 Ninja appliance air fries, sears, bakes with 75% less fat than deep frying, fast and versatile healthy cooking](https://a.co/d/gWhBCZL). If you can only have two, I recommend something like this and a microwave. If only one, honestly I think this is more versatile than a microwave and makes better food in general. This is the model my parents have, not sure if there is something else out there more suited to your needs but I've done a lot of different meals in this thing (toasting, reheating, searing, oven, air frying, etc) and to my knowledge it truly does work well at the different cooking types it claims (again have tested/tried everything, just the more normal stuff and have enjoyed using it). The benefit of this particular one is that it has a pivot stand, so you can fold it up out of the way when not in use to reclaim some of your counter space. My dad likes to leave it up and I like to leave it down cuz I constantly have to clear clutter away to fold it down. I've compared making roasted vegetables in the oven and in this machine and I tend to prefer this machine over the oven. Plus if you're cooking for only one or two, the size is about right for it and not too hard to clean (unlike having to try to clean the whole glass stove stop, not hard just a lot more surface area). I don't mean for this to sound like an ad, like I said this is the one I have and I like it. There are likely other versions of this same style (a combo unit designed to be multiple machines in one). Likely a good version of each machine would perform better in its specific category, but a combo unit like this achieves I think 90% of the same result or sometimes better in rare cases, but has the benefit of less room being taken up since it's one machine, and it can be folded up for more counter space. When I get my own place, I am planning to either get myself this one, or look at what is available and try to find something even better if it's an option, and won't worry about other appliances until I actually need them (cuz this does pretty well by itself).
r/Cooking • View on Reddit →My opinion:- Cook two different things/temps at once! I've got a ninja dual, and love it, used at least every other day if not daily
r/airfryer • View on Reddit →The third one in the list, the Ninja Air Fry Oven, was terrible for me. So much grease would get everywhere even when using the drip pan. I went to the first one in the list, the bucket style Ninja, and it's so much better.
r/airfryer • View on Reddit →I actually just got a separate thermometer so I'm not sure yet but the separate one actually tells you the temperature. The ninja one you just set it to rare, medium,ect and I find it over cooks. I'd rather just see the actual temperature.
r/airfryer • View on Reddit →Yup, I have the same one. I use it every day and it is extremely easy to clean. However I dont use the inserts that came with it. Those werent the easiest to clean. I use a grill rack instead. So Im just cleaning the basket which is teflon coated and the grill rack which is stainless steel. It cooks really quick and unless youre flipping something its set it and forget it.
r/airfryer • View on Reddit →If you're in North America, there are air fryers that purport to run multiple baskets at the same time (ie: Ninja Dual). Our home power supply will not run both baskets at the same time at full heat; the user's guide says you have to allow almost double the time if you want to use both baskets at once as the temperature won't reach full heat. Evidently they do work at full speed in the UK. That being said... I also have a Ninja Foodi multicooker that does the whole slow cooker/pressure cooker/ air fryer thing in one unit. I've had four or five air fryers and that's the one I've used the most because the multiple functions are useful for me. For just a dedicated air fryer, make sure it has enough physical space to cook the amount and kind of food you want. For example, french fries are best cooked in one layer. Many air fryers are not sized to cook enough fries to feed four people. Whichever air fryer you choose, you'll need to peek in and toss/shake/shift your food two or three times during the cooking to get everything to cook evenly, so ensure it's a convenient size, weight etc.
r/airfryer • View on Reddit →If you tell it to have 375 in one side and 350 in the other they'll actually be about 335 and 310. It can't output enough heat.
r/airfryer • View on Reddit →I have both and use them for different things. Messy foods like chicken, etc go in the basket fryer (Ninja Dual) but things I prefer to "bake" or make larger quantities of, go in the oven; my model has a basket tray which allows for good air circulation.
r/airfryer • View on Reddit →My first attempt yes I just did what I would have done if they were alone. Tried later adding time and found it really cumbersome to get right. It just doesn't get nearly as hot when splitting between both baskets
r/airfryer • View on Reddit →I bought a dual-fryer Ninja just because I didn't know any better. Wish I had a single basket now.
