Yes, you can put aluminum foil in an air fryer, as long as it is weighed down by food and does not block the airflow. Keep foil in the basket, not the drawer, cover only part of the base, and never run the air fryer with loose foil, which can blow into the heating element. Avoid foil with acidic foods, which can react with it.
Yes, if the foil is weighted by food and does not block airflow. Never air-fry loose foil; it can hit the heating element.
How to Use Foil Safely
- Place foil in the basket, weighed down by food so the airflow cannot lift it.
- Cover only part of the base; leave gaps so air can circulate underneath.
- Never preheat or run the air fryer with empty, loose foil, which can fly into the element.
- Avoid foil with acidic foods like tomatoes and citrus, which react with aluminum.
When to Skip It
Blocking the perforated base with a full sheet of foil traps air and stops food crisping, defeating the point of the air fryer. Parchment paper or the basket itself is often better. The same airflow rule applies to parchment paper, and in the oven, see can you put aluminum foil in the oven. Choose an easy-clean model from the best air fryers.
Frequently Asked Questions
Is it safe to put foil in an air fryer?
Yes, if it is weighed down by food and does not block the airflow. Loose foil is the danger, as it can blow into the heating element and cause a fire.
Can you line the whole air fryer basket with foil?
No. Covering the entire perforated base blocks airflow and stops food crisping. Leave gaps, or use perforated parchment instead.
