Yes, you can use aluminum foil in an air fryer—but with caution. Always check your air fryer’s manual first, as not all models permit foil use. When allowed, aluminum foil can help prevent sticking and make cleanup easier, especially when cooking moist or delicate foods like fish or marinated vegetables.

However, improper use can lead to problems. Never block the air vents or completely cover the basket—air fryers depend on proper airflow to cook food evenly. Also, make sure the foil is secured and doesn’t touch the heating element, as this could cause a fire hazard or damage your appliance.

Foil isn’t ideal for crispy foods like fries or chicken wings, as it traps moisture and prevents that satisfying crunch. For those looking for alternatives, silicone liners and parchment paper liners are popular. Silicone is reusable and dishwasher-safe, while parchment paper is disposable and great for easy cleanup.

No matter which liner you use, be sure it doesn’t interfere with air circulation. Used properly, foil and other liners can enhance your air frying experience—just follow safety tips and your model’s recommendations to keep things crisp, safe, and delicious.
