Air fryers have become a popular household appliance in recent years. However, improper use of this device can lead to food poisoning.

British nutritionist Nicola Shubrook explains that an air fryer cooks food by circulating hot air around it. This process creates a crispy outer layer, reduces fat content, and is convenient for preparing foods like fries and fried chicken.

However, when using an air fryer, home cooks must adhere to basic rules to avoid foodborne illnesses.

Not Preheating the Air Fryer Before Cooking

Most air fryers on the market come with manufacturer instructions recommending preheating the appliance. Users are advised to heat the air fryer for about 3–5 minutes before setting it to the desired temperature and placing food inside. This ensures more accurate cooking temperatures and enhances food flavor and texture.

Overloading the Air Fryer

An air fryer essentially works like an oven, circulating hot air around its interior. Overcrowding the basket can prevent hot air from reaching all sides of the food evenly. As a result, the dish may turn out less crispy, and the color might not be as appealing.
