I have a small 3 QT Power XL and a Cooks Essentials 5.3 QT. TBH, I don’t look on this as a substitute for deep frying as I think it falls short. What I love about air fryers is that it’s wonderful for reheating most foods–I’m a widow and it’s hard to cook for just one–and it doesn’t give that awful microwavy taste you get nuking stuff. Like this recipe I can bake small amounts and you will never roast a chicken in a conventional oven after doing one in here. It also doesn’t heat up the kitchen very much and that’s a plus in the summer. And it’s pretty fast because what it really is is a very powerful but small convection oven. A chicken that normally takes 2 hrs in the oven will cook in about 70 minutes in this.
