Many home cooks rely on aluminum foil for various reasons. Whether it’s to line baking sheets, wrap food for storage, or even create makeshift cooking vessels, aluminum foil has its uses. But when it comes to air fryers, can you use it without compromising safety or cooking results?
It’s no secret that aluminum foil has a convenient spot in many kitchens, and you’re probably tempted to toss some in your air fryer too.
It can potentially make cleanup much faster and keep delicate foods from falling through the grate. Although there are differing opinions, you can put aluminum foil in an air fryer as long as you take certain precautions.
Let’s take a look at how to safely use foil in an air fryer and address the valid concerns regarding aluminum and health.

Understanding the Function of an Air Fryer
Air fryers use a heating element and a fan to circulate hot air. They are essentially mini versions of a convection oven, where the hot air circulates around the food to crisp it up on all sides. This rapid air circulation mimics deep frying, crisping up the exterior of your food and creating a delightful texture.
It’s vital to understand that this airflow is key to achieving those crispy results. But can you put aluminum foil in an air fryer without affecting how the air circulates?
The Importance of Airflow
Airflow in your air fryer is just like proper ventilation in a traditional oven: you don’t want to block it. Air fryers work by circulating hot air, originating at the bottom of the fryer, and it's important not to obstruct this airflow to ensure even cooking.
Blocking the airflow could cause uneven cooking and soggy results. Using aluminum foil in an air fryer could affect the cooking times of your favorite recipes.
How to Safely Use Aluminum Foil in Your Air Fryer
It’s perfectly fine to use aluminum foil in an air fryer in certain instances; however, there are specific methods to ensure safety and proper cooking. In an air fryer oven, it's important to line the grease tray with foil without obstructing airflow. For one, make sure the foil doesn’t interfere with the airflow.
Placement Matters
When using foil, always place it inside the basket where your food sits. Make sure it doesn't block the heating element at the bottom of the air fryer or cover the entire basket.
Secure the Foil
Make sure your aluminum foil is weighted down by food. A small piece of loose foil can get blown around by the powerful fan and could potentially come into contact with the heating element, presenting a fire hazard. Make sure you either crimp the edges or use heavier-duty foil to minimize movement.
And don’t forget that aluminum can react with acidic foods like vinegar, tomatoes, or citrus juices, so using foil when air frying foods containing those ingredients is best avoided.
Manufacturer Recommendations
Just like any other appliance, consulting the manufacturer’s guidelines is wise. Guidelines for using foil can vary between air fryers and air fryer ovens, including those with racks and removable baskets.

When to Put Aluminum Foil in an Air Fryer: Optimal Applications
You’re likely already familiar with using aluminum foil to keep foods from making a mess in your traditional oven, and the same benefits can be found when using it with an air fryer.
Mess Reduction
Foods that drip or have sauces are particularly messy. That’s when a little foil is helpful. It creates a barrier and minimizes contact between those drippy ingredients and your air fryer basket.
Simply lining the basket with a small piece of foil before you add those juicy chicken wings can save a ton of scrubbing afterward. This is an especially useful kitchen tip when preparing your next batch of chicken wings or onion rings.

Small, Loose Ingredients
Ever tried air-frying breaded items like mozzarella sticks or chicken nuggets? Those crispy little bits of breading inevitably escape through the air fryer basket, creating unnecessary messes. A well-placed layer of aluminum foil prevents these bits from falling and potentially burning on the heating element.
This trick also keeps smaller vegetables like broccoli florets from tumbling out and also works well with foods prone to sticking to the basket, such as eggs. Just make sure that if you’re making a meal like scrambled eggs or omelets the foil is shaped to create “cups” that contain them.
Moisture Retention
Believe it or not, foil can be used in an air fryer to retain moisture in certain dishes. Have you tried reheating something previously cooked that gets dry when heated too much, like chicken or pizza?
By lightly wrapping it in aluminum foil, you can keep that dryness from occurring and warm up foods more evenly. This can be quite handy when preparing side dishes that require a touch of moisture retention.
Alternatives to Foil
Sometimes you need something a little less reactive than aluminum foil or more breathable. Fortunately, there are good alternatives.
Parchment Paper
This heat-resistant, non-stick paper can be a great option for less messy foods that you want to keep from directly touching the basket. It’s best with food items already in a compact form, such as chicken breasts, salmon, or vegetables like sliced potatoes.
But use caution with it because parchment paper is much lighter than aluminum foil and tends to blow around easily, which could be a safety concern. You might be wondering, can I put parchment paper in an air fryer? The answer is usually yes but check the manufacturer's instructions to be sure.
Silicone Baking Mats
You’re probably familiar with silicone baking mats that work so well in a conventional oven, and now you can get versions specifically for an air fryer. Not only will they help reduce messy cleanups, but you can also reuse them.

Considering Aluminum and Health
There’s a reason some manufacturers discourage using aluminum foil or caution you about using it with acidic foods, which has to do with the potential for aluminum to leach into food.
Although you can put aluminum foil in an air fryer without harming your health in moderation, using it too often with acidic foods could have long-term effects. This is especially important if you're focusing on healthy food and watching your aluminum intake.
Aluminum Intake
It’s true that everyone has trace amounts of aluminum in their system, and a normal amount is considered harmless. But with an abundance of sources from deodorants to foil and certain types of cookware, our systems are exposed more frequently, especially with acidic foods.
Studies suggest that higher amounts of aluminum exposure over time may pose health risks. So, while using foil for your 4th of July barbecue sides might be okay, be mindful of your regular usage.

The Potential for Toxicity
This topic can be scary and needs more research before anyone will say that aluminum has a definitive negative effect on our health; however, there is cause for some concern.
While more conclusive evidence is still being gathered, some evidence points to aluminum being linked to neurological diseases such as Alzheimer’s. But to avoid panic, let’s focus on more manageable lifestyle changes.
Limiting Toxin Exposure
Being more conscientious of how we use foil, limiting exposure to acidic foods, and replacing it with alternative solutions as often as possible can all help limit exposure. For those concerned about what they cook their food on, this is a great opportunity to research what is the best thing to put on the bottom of an air fryer for their specific needs.

Conclusion
It is generally safe to put aluminum foil in an air fryer with proper placement and moderation. Avoiding contact between foil and the heating element is crucial to prevent safety hazards. Aluminum foil offers convenience, mess reduction, and the potential for better cooking in specific recipes.
Although you can put aluminum foil in an air fryer without compromising your health, try to use it minimally or with non-acidic foods due to the potential for aluminum leaching and possible health concerns. Remember, exploring alternative liners such as parchment paper or silicone baking mats is worth it, too. Happy air frying!
