This one. I bought the nonstick basket tray, and it's phenomenal. I wish it had come with that instead of the mesh one. https://www.kohls.com/product/prd-7372994/ninja-12-in-1-doublestack-xl-countertop-oven-and-air-fryer-dct601.jsp?skuid=72012821&CID=shopping30&utm_campaign=PREMIUM%20ELECTRICS&utm_medium=CSE&utm_source=google&utm_product=72012821&utm_campaignid=20558767392&CID=shopping30&utm_campaign=KMN&utm_medium=CSE&utm_source=google&utm_campaignid=20558767392&gclsrc=aw.ds&gad_source=1&gad_campaignid=20564910854&gbraid=0AAAAADytpHYK6EbxDULvjdKrxNcGSFn3R&gclid=CjwKCAjwwpDQBhAuEiwAa-4Wo-fgiJnSTfkEPk9SPvVf6cPuE0OKmAF5HxnDxaz9vcFAaAYYpjQ0EhoCmAoQAvD_BwE
We have a Ninja 12-in-1 double oven with FlexDoor. Love it. Our oldest has since moved out, but we were a family of 5, the oldest been a teen boy with a voracious appetite.
I'd get a "Ninja Double Door 12-in-1 Countertop Electric Convection Oven & Air Fryer with FLEXDOOR" I was gifted one and thought it would be lame. Boy was I wrong. We barely use our main oven anymore unless we're making a large roast or something that won't fit in the mini oven. Wait for a sale.
We love the ninja 12 in 1. We never use our full size oven. Air fries, bakes pizza, deserts, it's honestly flawless. Bake and air fry at the same time. Even replaced our toaster https://www.target.com/p/ninja-1800w-double-stack-xl-countertop-toaster-oven-and-air-fryer-with-smartfinish-38-dualzone-technology-stainless-steel-finish-dct601/-/A-91722292
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
They don’t have anymore, so glad I got it when they did, I don’t even use my oven anymore
We have a Ninja Double Stack XL Countertop Oven and Air Fryer. They cost about $300. Just my wife and I in the house. We love it. About the only time we use our regular oven is when we are making cornbread in a cast iron skillet or baking a big pizza.
