I got a Ninja 11 in 1. It’s does a bunch of stuff including air frying, pressure, cooking, slow cooking etc in general it’s great and I get good results with it but it’s huge. I’d definitely look at something like this if I were you and you’re open to getting rid of some kitchen gadgets to combine into one. That being said I use the pressure cooker and slow cooker bits a bunch and only dabble in air frying as an alternative to deep frying and for speeding up roasting things. Most common things in the air fryer are, home made fries, wings, quick roast potatoes, home made chicken tenders and breaded fish fillets I should really expand the repertoire here but it’s quick and to some extent fire and forget for these basics
Yes! I bought the Ninja® Foodi® 10-in-1 6.5-Quart Pro Pressure Cooker Air Fryer Multicooker, etc. It has ten different functions and can do so many things. I can use it as a crock pot, sous vide, instapot, pressure cooker, I can brown foods in it before I do the crock pot or pressure cooker function. It saves on electricity and it doesn't put off any heat. I'm prefer to cook with it anytime of the year, but especially in the summertime.
I have the Foodi, the one that doesn't need a separate lid. I've had it for around 3 years I think. It's a big chonky machine, but I love it and recommend it to everyone. I use it more than the hob at this point! The modes I use the most are air frying, pressure cooking, sear/saute and bake. The stream to air fry mode is also great for making a whole chicken! My boyfriend has been using it when at my place and likes it so much he's going to replace the Instant Pot he has at his place with a Foodi because he wants an air fryer and it's much nicer to have it all in one. The one downside it has compared to a normal air fryer is that the basket is not very big, and it's also quite noisy compared to dedicated air fryers. Personally, the trade off is worth it for me. Happy to answer any more specific questions!
Decent for the price with okay warranties. I have a Ninja Foodi air fryer/pressure cooker/slow cooker/all in one jawn that sits on my counter and get's used like 3 times a week minimum. It's one of my favorite appliances in my kitchen because I primarily use it as an air fryer but it can also be a second slow cooker for when I'm making a huge meal. The steamer function on it is pretty tight as well, boa buns come out perfect from it. The coffee makers are also decent but I wouldn't use them for high end things like espresso. A simple ninja drip coffee machine will be just fine though. Blenders again are decent but ill not outperform something like a Vitamix or more high end. Knives? The knife block is okay but I hate pull through sharpening systems and am generally against buying sets as a whole. You only need a few good knives. Generally Ninja makes decent things that will do the thing they are advertised to do. They won't do them exceptionally well as compared to products that specialize in said task but they aren't poor quality items either.
I have a Ninja foodie which is an air fryer plus insta pot. It's a great space saver. While we don't use either option often, it's nice to have when we do want to use it
I have a ninja foodie which is an insta pot and air fryer. We actually use the insta pot part more than the air fryer but it's nice that I don't have 2 things taking up space
I got the ninja foodi pressure cooker and air fryer combo a few years ago and it quickly became the most used appliance in the house. I initially had thought that it too was a glorified convection oven but got it anyway because I was looking for a pressure cooker. The key difference is that it can really get the air moving, eliminating steam pockets that prevent crisping. It only takes 2 minutes to preheat. And since it doubles as a pot, it also does stews. The big hack for me is that I can cook and brown a large batch of minced meat on both sides by first frying the bottom with the saute mode till I get browning, then following it up with 5 mins of air frying to brown the top. all in the same pot.
