An air fryer is a kitchen appliance that cooks food by circulating hot air around it, creating a crispy outer layer similar to frying but with significantly less oil. This method allows for healthier cooking, as it can reduce fat content while still delivering a satisfying texture. Air fryers are versatile and can be used to prepare a variety of foods, including fries, chicken wings, and even vegetables. Many air fryers come with preset cooking functions, making them user-friendly for people of all cooking skill levels. They typically feature adjustable temperature settings and timers, allowing for precise cooking. With their compact design, air fryers are a popular choice for those looking to save space in the kitchen while enjoying delicious, healthier meals.
