This! We use our air fryer for everything - frozen tots, frozen fries, frozen onion rings. Chicken wings. Hard boiled eggs. Re-heating leftover pizza or meats. It keeps everything crispy, juicy, and not greasy so you get the fried food taste and texture without the oil.
did frozen arby's seasoned curly fries tonight and it was just like getting them at the restaurant (except not greasy). frozen battered fish filets turn out like fish and chips from the local pub. we use it WAY more than i ever anticipated, esp. since i found an oven to air fryer temp/time conversion chart online.
