It’s an alternative to grease frying. We don’t use ours like many do. My kids cook chicken nuggets in it. We like tater tots cooked in there. It’s also good for veggies. Works great for reheating things as well.
1000% yes! Get the biggest one you can. We regularly do a 3-4 lb chicken for two of us and end up with leftovers. 2 years in and we still do “air fryer Mondays”. Best kitchen appliance we’ve gotten past several years.
