The intention of the very first air fryer was to mimic the technique of frying using air and a small amount of oil. It works like a convection oven circling hot air quickly around the food in the air fryer basket. As a result the food inside comes out crispy. Because an air fryer is much smaller than a convection oven not only does it create crispy food, it also cooks the food more quickly. Note that depending on your air fryer, the cook time may vary for most of these vegetarian recipes.
