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
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).
I'm not a big fan of the ones that seem to be the most popular. You should buy the largest one you can afford and have counter space for. It's really a convection oven and if you have the room you could cook a chicken I have the Ninja dual oven where the bottom is an air fryer in the top is a toaster oven, I don't use it everyday, I use it several times a day I also received as a gift one of those that has the three stackable trays. It's okay but you have to rearrange the trays from time to time if you're cooking something that takes a while. And yes I do use both
I've got the Ninja dual oven with the little bitty top door you can open separately. I like it a lot.
I have a different ninja with a built in thermometer and I'd recommend a separate one anyway. It's not that accurate
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.
Air fryer was my introduction to teaching myself how to cook. Started off with simple recipes and later progressed to recipes with more components. Do you -need- an air fryer? No, but I definitely prefer using the air fryer over the microwave for heating up certain foods. I've used the air fryer to warm up pretzels, pizza, baked items, etc. But if you are going to pick up an air fryer, pick up the one with the bigger tray. I got the Ninja air fryer with the thermometer attachment. This lets me get food to a specific temperature. Was great when I didn't know what the heck I was doing. I'd put the thermometer into chicken, porkchops, steaks, etc. Then as I became more comfortable I needed the thermometer less and less. So, yeah, I think it's a good investment.
We got one of those Ninja all in ones like you're considering and we use it daily, not only for toasting but baking, air frying, etc. I rarely use the oven now. We also removed the toaster for counter space. It's a good idea IMO.
So I have two air fryers. Both are ninjas. One is single and one is dual. I do agree the single is better. It's really convenient to have three air fryers when making something like air fryer chicken, roasted veggies & fresh french fries. I can make all three at the same time and eat at the same time. Super convenient. Also if making wontons and spring rolls. I have a pretty busy job, a young child & a husband who doesn't cook. So for me worth it to have all. I also have enough space in my kitchen.
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.
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.
