An air fryer is a versatile kitchen appliance that uses rapid air circulation to cook food with minimal oil, mimicking the results of frying but in a healthier way. It features a compact design with a heating element and a powerful fan that crisps food on the outside while keeping it tender on the inside. Ideal for cooking a variety of dishes like fries, chicken, and vegetables, an air fryer is a convenient and energy-efficient alternative to traditional frying methods, offering a quicker and cleaner cooking experience.
