Air fryers will achieve similar effects as a full-size convection oven. However due to their small size they are much more affordable and convenient. Even large capacity air fryers use just a fraction of the energy of a traditional oven. One difference to keep in mind is the layout. While a full-size oven or a toaster oven will cook food horizontally on a baking tray, air fryers often have a more vertical layout, piling food into baskets when cooking. This requires you to shake your food periodically to ensure it’s all getting browned evenly.
