An air fryer is a small appliance that uses hot air and a small amount of oil to cook and crisp food. It is designed to provide a healthier alternative to traditional deep frying, as it uses less oil and can still produce crispy and flavorful fried foods. The "without oil" feature in an air fryer refers to the fact that this appliance is designed to require less oil than other cooking methods, such as deep frying. Electric air fryers are powered by electricity and typically have a control panel with settings for temperature and cooking time, as well as a basket or tray for holding the food being cooked. They are often used for cooking a variety of foods, including French fries, chicken, fish, and vegetables.
