Can I put aluminum foil in an air fryer?
How to use foil safely
Aluminum foil can be used to line the air fryer basket or tray to catch drips and make cleanup easier. However, it must be secured so it doesn't fly up into the heating element, which can cause a fire. Place it under food or weigh it down with the food itself.
Also, avoid covering the entire bottom of the basket. Air fryers work by circulating hot air, so blocking the holes in the basket will prevent proper cooking. If you use foil, poke a few holes in it to allow airflow.
Foil is safe for most foods, but acidic ingredients like tomatoes or citrus can react with aluminum and give food a metallic taste. For those, use parchment paper instead—just make sure it's weighted down too.
- Use foil only on the bottom, not covering the whole basket.
- Poke holes in foil for airflow.
- Never let foil touch the heating element.
- Avoid foil with acidic foods.
- Consider parchment paper as an alternative.
When to avoid foil
If your air fryer has a nonstick coating, foil can scratch it. Check your manual—some manufacturers recommend against foil altogether. Also, never use foil in a microwave or toaster oven unless specifically designed for it.
For easy cleanup, you can also use air fryer liners made of parchment or silicone. These are reusable and designed to fit the basket without blocking airflow.
Common mistakes
- Letting foil fly up into the heating element, which can cause a fire.
- Covering the entire basket and blocking air circulation.
- Using foil with acidic foods, which can leach aluminum into the food.
