Can you put aluminum foil in an air fryer? Yes. If you follow the proper safety precautions for using foil or foil pans in an air fryer, it’s not a problem at all. Unlike microwaves, in which foil must not be used, air fryers have no electromagnetic fields that cause the sparks and fires that happen in microwaves.
Let’s get into what you need to know to use foil safely and efficiently in your air fryer.
Is it safe to use foil in an air fryer?
As long as you observe certain safety precautions, foil is perfectly safe in air fryers. It won’t melt and ruin your food or air fryer because it can withstand up to 1220 degrees Fahrenheit (660 C) while the fryer ovens never heat to more than 320 degrees Fahrenheit (150 C).
Be sure that when you use a foil pan or foil, it does not prevent the fryer’s airflow or circulation of air while cooking. A bonus to using aluminum foil is that it helps evenly spread the internal heat throughout the food during cooking.
By checking the instructions manual of the fryer or checking specs from the manufacturer online, you can find exactly where in the fryer unit the flow comes from. DO NOT block that spot, and you will be good to go!
It’s best to use foil infrequently to avoid too much of it getting into your food and then into your body. While it’s safe when used properly, like wrapping food for a faster cook, it’s not safe if used with the wrong kinds of food.
See the additional precautions below for more information on how its use with certain foods has been associated with Inflammatory Bowel Disease and Alzheimer’s disease.
As with a conventional oven, aluminum foil will not spark up and burn anything in the air fryer like it does when used in a microwave. It’s a lot like using it in a conventional oven, except for the possibility that loose foil can block the small heat conductor in the air fryer, which is dangerous.
Other precautions:
- Don’t wrap acidic foods like tomatoes, peppers, fruits (especially citrus), sauerkraut, and vinegar toppings/marinades in foil. Those foods actually break down the foil and can leave tiny particles of foil in your food; these can be harmful to your health.
- Poke several holes in the foil on which you place your food because air has to get through the bottom of the basket weave to the food for the air fryer to work safely and efficiently.
- Don’t line the bottom of the fryer below the basket; the foil should only line the basket because the bottom needs to be significantly penetrable for the fryer to work properly and safely. WARNING: Foil below the basket can fly around, and if it covers the heat conductor, it can cause a fire! EVEN when preheating, do NOT put the foil in. It should only go in with the food.
- Use as small a sheet of foil as possible. Remember, air must flow upward into the food from the bottom of the basket, so you don’t want too much foil blocking that direction.
Is it toxic to put aluminum foil in an air fryer?
In general, the answer is no. Most foods like meats, breaded cheeses, burritos, non-acidic veggies like potatoes and carrots are not going to cause any safety risks when cooked on foil in an air fryer. And, foil, alone, is not toxic.
HOWEVER, when foil is used to cook acidic foods, as mentioned above (tomatoes, acidic sauces, citrus fruits, etc.) then there is a high risk that the heat from those foods will actually disintegrate some of the foil, causing small burnt/black particles of foil to get into the food.
Those particles CAN BE TOXIC and cause health problems. So, as long as you are careful about which foods you cook using foil or foil pans, there is no reason to worry about any harmful toxicity. Cook away and enjoy!
How much foil should you put in an air fryer?
As little as possible is the answer. With air fryer technology, the idea is to let hot air penetrate your food from all sides in order to give that deep-fried effect. If you have a sheet of foil covering the bottom of the basket or you place a foil dish in the basket in which you place the food, you will get uneven cooking.
It’s best not to use foil platters or dishes at all because it completely defeats the purpose of air frying other than the fact that your food will be healthier than if it were drowned in oil. You may as well cook it in a conventional oven if you plan to block the airflow from the sides and bottom of the air fryer.
And when you do line the basket bottom with foil, be sure to perorate it, so the air can flow through. This way you get the benefits of the even cook and the ease in lifting the food out of the basket using the foil–keeps your basket clean!
TIP: Double up some foil and create a strip (1″-2″ wide) to run up two different sides of the basket. You can use those as handles to lift out the entire sheet of foil without risk of burning yourself. Surprisingly, foil cools off almost instantly once removed from heat, unlike the metal of the basket.
Great foods to cook in an air fryer using foil:
- Air fryer meatloaf.
- Breaded fish.
- Chili-Cheese tater tots
- Baked honey ham
- Stuffed prawns
- Whole roasted garlic
The seafood is especially healthy because there’s no need to fry it in oil or butter to get that crisp coating on the fish or on the stuffing topping the prawns. Mmmm.

In conclusion, yes, aluminum foil can go in an air fryer. Just be sure to consider the above when using it. Happy cooking and eating to you!
