Obviously, because it can produce results similar to deep-frying using a tiny fraction of the oil needed to deep-fry, the health benefits are apparent. When deep-frying, you submerge the food in oil and oil is inevitably absorbed by the food. In an air fryer, you still use oil because oil is what helps crisp and brown many foods, but you really don’t need more than one tablespoon at a time. Instead of putting a tablespoon of oil in the air fryer, you simply toss foods with oil and then place them in the air fryer basket. In fact, spraying the food lightly with oil is an even easier way to get foods evenly coated with the least amount of oil. Investing in a kitchen spray bottle is a great idea if you have an air fryer.
