Ninja Foodi eight-in-one air fryer/oven ! Air fryer/oven/toaster oven/broiler. It flips up when cool to save counter space.

r/CostcoBest air fryer sold at Costco?

I have the basic Gourmia with the window, I find it a very good air fryer. I also own the Ninja 10-in-1 oven that includes an air fryer option, but it does not air-fry as well as the Gourmia. This Gourmia has really gone up in price since last year, but does go on sale from time to time. TIP: Costco now sells air-fryer parchment paper to help with any messy foods. Please do not put it in the air fryer until after the pre-heat, and make sure to secure it carefully with food in each of the corners. The first time I put it in duing pre-heat, and it exploded into flames. Quite frightening, but no harm came of it except a moment of terror. A pack of about 150 is $10.00.

r/CookingIs an air fryer worth it?
9 months ago

We went back and forth on one for years... finally bought the Ninja Foodie one that doubles as 7 other tools (oven, toaster etc) and we use it EVERY day. The reheat feature is crazy good and the flat design is the basket means it's actual better at being a fryer than the deep basket ones. Get one, best thing in our kitchen beside old cast iron pans!

Can anyone who has this speak to how difficult it is to clean? I have a similar toaster oven that's larger, but the drip tray and heating elements are a PITA to clean and it's got more space than this one.

I picked up the foil trick way too late on my current one, which is partially why I want to replace it. Buuut my current one still works fine, and I'm not quite convinced the space savings is enough to justify a new one.

Pizza is absolutely what screwed w/ the heating elements on my current one. If they were more easily accessible, it would perhaps be tolerable, but they're not.

Yep! I unfortunately didn't realize how quickly that stuff seems to meld to the racks/tray until too late. In attempts to clean it, the coating on those items started flaking, and now they're just a complete mess, which is partially why I want something new to start over so that I can "do it right."

r/airfryerWhy do you guys prefer dual air fyers?
7 months ago

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.

r/cookingforbeginnersBest budget air fryer?

Given all the research you’ve already done, you’ve probably seen that giant comparison database of air fryers floating around Reddit [here, I bookmarked it](https://www.reddit.com/u/MaterialisticOcelot/s/AuYboNaNB6). It’s super handy if you want to line up the details down to the very last spec. I personally have the Ninja Foodi and really like it, but I wouldn’t really consider it a “budget” pick since it runs close to $200. That said, I do think you get what you pay for with these. I’d be careful about going under $50 on an appliance you expect to last.

We've had ours that we bought at Costco for 3 years. Daily use if not twice per day because we are saving on gas 😂. I ended up making both pies for thanksgiving (one at a time) in here because the oven was full. Love that it has all the functions and is easy to clean. Preheats faster than a regular oven because it's smaller. We're a family of 3 so if you have a bigger family I would probably suggest a bigger one.

I second Ninja. I use my Ninja Foodi XL almost everyday. I’m almost ashamed. Feels like such a cheat to cooking haha! Gifted it to multiple relatives and they love it too.

I returned the ninja flip and got the cosori toaster oven. It does everything the flip does and it's bigger. A traditional basket air fryer is probably best for only air frying, but I wanted the other options as well. https://www.costco.com/p/-/cosori-30-liter-smart-air-fryer-toaster-oven/4000415415?adobe_mc=TS%253D1767411720%257CMCMID%253D73997581491133952237276407342534395761%257CMCORGID%253D97B21CFE5329614E0A490D45@AdobeOrg&mboxSession=5091034b-e479-47e9-a624-a1fdcb423789&sh=true&nf=true

Not entirely sure what you’re asking for here after reading the question a few times. That being said, there are 2 possible answers I believe you could be looking for: 1. The model number doesn’t match any on Ninja’s website. This is a common practice that vendors make a Costco specific model to identify it as being purchased through Costco because often Costco has agreed to difference to the warranty as part of there purchasing agreement, or otherwise it’s a different bundle than is offered at other vendors. 2. You want an actual review of the product. I have this unit, got it with a coupon a few years ago, and I love it. Bought it primarily for the broiler function because my propane oven would melt its knobs every time I’d use the broiler. It’s now become my primary, oven, broiler, and toaster. I have also used the “air fry” function and it works really well too. Hopefully you find the answer you were looking for.
