In addition to promoting healthier cooking, one of the main reasons we use an air fryer is for its quick preparation time and easy cleanup. To make cleaning even simpler, many people use liners in their air fryers. But can that liner be aluminum foil?
In this article, I’ll explore how to safely use aluminum foil in an air fryer. I’ll also cover what to avoid when cooking with foil, along with the best ways to use it effectively inside your air fryer.

Is It Safe to Put Aluminum Foil in an Air Fryer?
Yes, aluminum foil is generally safe to use in an air fryer, as long as it’s used correctly.
Before doing so, it’s important to check your air fryer’s user manual to confirm whether aluminum foil is approved for use in your specific model. If it is, you can safely line the basket or wrap your food in a single, continuous sheet of foil. Avoid using small or loose pieces, as they can get blown around by the circulating air and potentially block the vents or even pose a fire hazard.
Unlike microwaves, which use electromagnetic radiation and can be damaged by foil, air fryers rely on heated air circulation (similar to a convection oven). This means that foil behaves in an air fryer much like it would in a traditional oven: it helps conduct heat evenly and retains moisture, resulting in juicy, flavorful meals.
However, foil should only be used in certain areas. You can line the bottom of the basket, but never cover the heating element or fan, as this can interfere with airflow and cooking performance, or worse, lead to overheating.
Using aluminum foil won’t negatively impact the taste of your food. In fact, it can enhance flavor by catching juices and drippings that might otherwise be lost, helping your meals stay moist and delicious.
To avoid folding aluminum foil, there are already made air fryer liners. I recommend these Aluminum Foil Air Fryer Liners you can find on Amazon. These liners are comprised of the outer parchment layer and the inside aluminum layer.
The aluminum used is high-grade and resistant to oil, water, and high temperatures, and the double layer makes your cook safer, more straightforward, and the cleanup faster than ever.

Benefits of Cooking With Aluminum Foil
Although it might not seem obvious at first, cooking with aluminum foil in an air fryer offers several practical benefits:
Easier Cleanup
Lining your air fryer basket with aluminum foil can significantly reduce cleanup time. Once the food is done, you can simply lift out the foil along with any crumbs, grease, or residue, leaving the basket nearly as clean as when you started. This saves time and effort, especially after cooking messy or oily foods.
Cooking Foods You Otherwise Couldn’t
Air fryer baskets typically have perforated bottoms to allow for optimal air circulation, which works great for many dishes. But not for everything. Foods like eggs or items with sauces can be tricky to cook directly in the basket, as they would drip through the holes.
Using aluminum foil to line the bottom creates a flat, sealed surface, allowing you to cook more delicate or liquid-heavy items without making a mess or losing flavor.
Catching the Drippings
When you’re air frying a steak or roasting a juicy piece of chicken, the drippings are often the most flavorful part. Lining the basket with aluminum foil helps catch those savory juices instead of letting them drip through the holes and go to waste.
You can use the collected drippings to whip up a rich sauce to complement your meal or even toss in some vegetables and air fry them in the flavorful juices. It’s a great way to maximize taste while keeping cleanup minimal and cooking time short.
Aluminum Foil Distributes the Heat Evenly
Aluminum is an excellent conductor of heat, which means foil helps distribute the fryer’s heat more evenly across your food. This is especially beneficial when you’re cooking items wrapped in foil.
Normally, food placed closer to the air fryer’s heating element cooks faster, leading to uneven results. Wrapping the food in aluminum foil evens out the cooking process, ensuring that everything cooks at a consistent pace for perfectly done meals without overcooked or undercooked spots.
Preparing More Than One Thing at a Time
One of the advantages of using aluminum foil in an air fryer is that it allows you to cook multiple items at once without mixing flavors or creating a mess.
By lining the basket and folding flat pieces of foil to create separate sections, you can easily cook your meat on one side and vegetables on the other, all in a single batch. It’s a simple and effective way to save time while preparing a complete meal.
Keeping the Moisture In
Every cook knows how tricky it can be to strike the right balance between tenderness and thorough cooking. Wrapping food in aluminum foil helps solve this problem. Just like in a traditional oven, enclosing your ingredients in foil inside the air fryer traps moisture and steam, helping your food stay juicy and flavorful.
This method not only enhances the taste but also simplifies the cooking process, delivering delicious results with minimal effort.
How to Safely Cook With Aluminum Foil in an Air Fryer
Since cooking with aluminum foil in an air fryer is not only safe but also offers numerous benefits, here are a few helpful tips to get the most out of it:
Line the Basket
This will not only make cooking easier, but it will help with a faster cleanup as the air fryer basket itself will not get dirty or greasy. You can lift it in one piece and just throw it in the garbage.
Use Aluminum Foil to Lift the Food Up
If you are preparing a steak that you want to sear well, scrunch up the foil and use it as a step that will raise the meat closer to the heater. This will allow the meat to get a stronger sear, but if you decide to use it this way, keep in mind that at some point, you will have to turn the meat to get the browning on the other side as well.
Adjust the Use of Aluminum Foil to the Preparation of the Dish
If you want to steam the dish, wrap it in aluminum foil completely. If you wish to have something broiled, leave some openings in the foil when wrapping your food, or create them all around the lining of the basket.
The holes will allow the hot air to circulate around your ingredients and help get them crispy.
Which Foods Should Be Avoided When Cooking With Aluminum Foil in an Air Fryer
When using aluminum foil in your air fryer, avoid foods that have a high level of acidity. Avoid vinegar or lemon based marinades and foods such as tomatoes, rhubarb, lemons, and oranges.
Aluminum foil also reacts to a high dose of salt or intense spiciness: such foods cause local corrosion of the material, and although this is not dangerous to health, it is better to avoid it.
What Can You Use Instead of Aluminum Foil
Although cooking with aluminum foil poses no threat to your health, some people are still quite apprehensive. If you need an alternative to aluminum foil, you can always choose to use parchment paper.
Since cutting and forming parchment paper in the perfect size and shape you need for your air fryer, you can bus premade parchment paper liners. I recommend you try these Air Fryer Disposable Paper Liners from Amazon.
These high-quality parchment liners are waterproof, oil-resistant, non-stick, and heat-resistant. They won’t break or tear, and using them will make cleaning up after cooking a breeze.
If you are looking for a more eco-friendly side of things, you can also opt for reusable liners like this Air Fryer Silicone Pot you can find on Amazon.
This dishwasher-safe silicon pot is a cost-saving alternative to using disposable parchment paper or aluminum foil liners. It is made from high-quality medical-grade silicone safe for food preparation and is non-stick, non-toxic, and BPA-free.
Conclusion
Using aluminum foil in the air fryer is not only safe, but it can also be very handy. It is essential to follow the rules: use foil in one piece and do not block the heater and air fryer fan.
If you keep that in mind, the only limit is your imagination; with aluminum foil, you can bake, cook, reheat, broil, and steam, and it also makes cleaning easier after the meal is prepared. So fire up the air fryer, get the aluminum foil out of the cupboard and get ready to make some tasty treats!
