As we have mentioned that air fryers work like a convection oven, so you may conclude that it might be better than ovens. The mechanisms might be the same, but the hot air is circulated with rapid air technology, compared to that of the usual convection oven. We think that air fryers are definitely a great option for your home, but it doesn't have the potential to fully replace a convection microwave oven. In a full oven, you can cook more food compared to the biggest size of an air fryer. You definitely love to have one to specifically use to prepare fried things.
