We have an air fryer and like it for making french fries. After drizzling them with healthy oil we fry them for about 15 minutes (stirring every 5 min). Make sure they are starting to brown before serving. That way they will be crunchy on the outside and soft in the middle. We also use it for warming leftovers and making toast. Chicken breasts that have been dipped in butter and rolled in crumbs turn out nicely.
