r/cookwareair fryer black friday and cyber monday deals, when should i actually buy?

Went with the Ninja 10 in 1 off Amazon for $249 DT551. Have the basket version and use it everyday. Hope to eliminate the toaster oven, toaster , and basket fryer for 1 device. The brand has held up well for us.

r/airfryerWhat's the best air fryer for 2026?
4 months ago

I purchased a Ninja Prestige Smart XL air fryer oven from Best Buy. Normally $429.99 and still on sale for $279.99. I got it for $249 on Black Friday. Yes it’s an expensive air fryer and oven style but I like it better than the basket style Ninja air fryer I had that finally quit working. I can cook more food at once and the air fryer function works just as well. It also has a thermometer probe you can use to cook food to the exact temp you want. I cooked a whole chicken a couple of weeks ago and it was falling off the bone using the air roast setting. Only complaint is that it’s a little harder to clean. Most of stuff it comes with is hand wash only and the glass on the door gets greasy fast. But would 100% buy again.

r/cookingforbeginnersCan an airfryer completely replace an oven?
9 months ago

I have the ninja smartXL and it replaces just about everything I do in the oven except bake bread. Only because I bake a few loaves at a time. I would 100% go for it. Less heat in the house too.

Imam ninja foodi xl sa 2 korpe, smart verzija. Najčešće spremam piletinu i pomfrit. Ubaciš čitavo pile, ubodeš termometar i to je to. Ima recepata milion, spremaju ljudi svašta. Recimo bilo šta svinjsko ne volim stavljati u airfryer jer mi bude suvo, dok piletina bude savršeno sočna.

They sell this exact model other places as well. Found it at Costco, returned it and bought it from Woot for 40 bucks less. Its a great machine, no regrets. Ninja 10-in-1 Digital Air Fry XL Oven https://home.woot.com/offers/ninja-10-in-1-digital-air-fry-xl-oven-3?utm_medium=share&utm_source=app

I just picked up a Ninja Pro 10 in 1 and think it’s awesome so far. I’m picky about my kitchen equipment too.

I read point 2 and love my toaster ninja xl airfryer oven and than my basket style because of it’s versatility.

r/AskRedditwhat's the best airfryer?

I imagine “best” is a matter of trade offs and perspective, just like most things. Our Ninja XL has completely replaced our full-size oven, we love it and use it almost every day. There’s a really cheap air fryer in my office’s break room, I realize sometimes budget is the most important thing for some people, but I would never buy something like that one that rarely works, cooks uneven, and looking at the melting plastic parts it looks like it’s going to cause an emergency someday.

I have the Ninja XL and love it, however, you might want to consider just buying one you like with an extended warranty. Normally I avoid those like the plague but they make sense for something like this. Get a 4 year warranty on a $150 AF, knowing with high usage you will cash in.

r/airfryerAir fryer vs Toaster Oven Air Fryer
9 months ago

I have a Cosori toaster oven style air fryer (some of my kids are all bougie and have Breville and the other a Ninja). All are terrific because they can all make a frozen pizza to perfection. Yes, longer pre-heat compared to a basket...by maybe a minute. My kid with the Ninja XL can make a full dinner with sides all at once for her and her husband, so that versatility is off the charts. I find with the mesh basket tray on my Cosori that I don't have to flip foods and they're much easier to space out to allow the circulation that is the science behind why an air fryer works.

r/CookingDo you have an air fryer? Should I get one?
6 months ago

I have the toaster oven style. Got the Ninja Flip one, loved it! Then I got the Ninja XL, love it even more! The Flip takes a bigger tray, but the XL takes two smaller trays. Flip would be great for a single person, the XL is great for my partner and I. I can't imagine trying to cook in one of those tiny basket type. They were never an option for me.
