How Does an Air Fryer Work?

Modern air fryers are a surprisingly simple design. They are usually a box or cylinder shaped appliance with a lid on the top. Inside the air fryer is a stainless steel wire basket with a drip pan underneath to catch oil and juices from the food. All you have to do is to place your food into the basket, apply a light coat of oil to promote a brown crispy texture, close the lid, set temperature and set a timer.

Most of these less-oil fryers come with cookbooks that tell you the proper temperature and cooking time for each food you prepare. You just set your fryer to the right temperature and set a timer. The air fryer will instantly begin producing superheated air at the set temperature, and then its fan will circulate the hot air around your food. When the time is up, you will get nice, crispy, oil-less food that doesn’t have as many calories as you would get from foods fried in heavy oils.

For foods high in fat like chicken, most of the fat and grease simply drips off into the drip pan. Air fryers are a surprisingly effective and easy way to cook virtually any foods. In fact, you can even bake a cake inside your new air fryer!
