Can You Put Aluminum Foil In An Air Fryer? (silver kitchen foil, tin foil trays & more)
The short answer is yes, you can put aluminum foil in an air fryer but there are certain conditions that need to be met first. Keep reading for the full story and the safe way to use kitchen foil in your air fryer.
Before Putting Aluminum Foil In An Air Fryer…
Before we go any further, we need to urge you to check the user manual that came with your particular air fryer. There are a few reasons for this;
- There are different types of air fryers
- There are a few companies that advise against using aluminum foil in their appliances
- Certain foods cause a health threatening reaction when exposed to aluminum foil and heat
So let’s now take a look at how they work to make this more clear.
How Does An Air Fryer Work?
It’s important to understand how an air fryer works as this will give you a clearer understanding on issues of safety.
An air fryer is basically a mini convection oven, because air fryers circulate hot air around the food as it cooks. It’s this constant circulation of hot air that gets the food crispy on all sides.
Inside every air fryer is a heating element just like you would find in a convection oven. Depending on the type of air fryer you have, that heating element will either be at the top or the bottom of the air fryer.
The two different types of air fryer are;
- Oven type air fryer
These models have the heating element at the top of the air fryer. - Basket type air fryer
These models typically have the heating element at the bottom of the air fryer, below the basket.
It’s really important you know which type of air fryer you own because how you can use silver foil in it is dictated by the type of appliance you are using.
You must never block the flow of heat that’s circulating around the air fryer. To do so could prevent it from working as effectively as it should.
This means using tin foil in a basket type air fryer is slightly more complicated than in an oven type.
Using Silver Foil In An Oven Type Air Fryer
To prevent any of the juices from your food or any breadcrumbs from falling into the grease tray of the air fryer, and make it far easier to clean, simply line the grease tray with tin foil.
This means any fat, meat juices, breadcrumbs, melted cheese, etc will land on the aluminum foil which can be removed after cooking. Leaving the grease tray clean and food free.
If you want to cook the item in foil, like many fish dishes, it’s OK to do so but be sure to not cover the whole tray with foil.
All types of air fryers need air to circulate all around the food for it to cook properly. If the tray is completely covered with kitchen foil, it will prevent that steady flow of air and cause the food to not be fully cooked.
The best way to prevent food from sticking to the tray in an oven type air fryer is to lightly grease the tray before placing the food on it.
Food cooked in an air fryer is supposed to be crispy and the use of too much foil will prevent the food from crisping up as it should.
However it is possible to create an even crisper skin on chicken etc by crumpling kitchen foil and putting it in the basket and placing your chicken thighs on top.
Using Aluminum Foil In A Basket Type Air Fryer
Using tin foil in a basket type air fryer can be slightly different than using foil in an oven type model, depending on your specific air fryer.
Heating Element On The Bottom
The heating element on some basket type air fryers is located at the bottom of the air fryer (under the basket).
This means that for those ones, there is no absolute way to use silver foil to catch all of the grease, breadcrumbs, etc.
However, it is possible to use foil in these types of air fryer as long as you don’t cover all of the holes in the basket with foil.
The holes are there to allow the hot air to flow all around the food that’s being cooked in the basket. If tin foil blocks all of those holes, the food will not get crispy and you run the risk of damaging your air fryer.
Heating Element On Top
With that being said, not all basket type air fryers have the heating element at the bottom, there are some that have the heating element at the top (and these are becoming more popular).
On these models it is possible to place tin foil on the bottom to catch any spillage.
This is why it is important to consult your user manual before applying any kitchen foil to your air fryer.
Keep The Kitchen Foil Weighed Down
Due to the way hot air is circulated in an air fryer and in particular a basket type air fryer, you’ll need to stop the foil from coming loose and flying around in the oven.
This could be dangerous and seriously damage the air fryer. The easiest way to prevent this is to weigh the foil down. Either with the actual food that’s being cooked or by using pastry weights.
- CERAMIC BAKING BEANS: The ultimate baking tools for perfect blind baking! The Tala baking beans are ceramic stones that help prevent pie dish crusts or other pastries from shrinking and blistering while baking. Covers a 32cm tart tin
- FOR FLAWLESS BAKING: Made from heat-resistant ceramic, these reusable pie weights help distribute heat evenly and keep the pastry flat so you get a crisp even bake without air bubbles. Simply hand wash the blind baking beans and store until the next use
You should always leave as many holes in the basket clear as possible to allow the hot air to flow.
Is It Safe To Use Aluminum Foil In An Air Fryer?
Unlike a microwave oven, it is safe to use aluminum foil in an air fryer. The foil will not spark and burst into flames like it would in the microwave.
However, there is some debate about whether it is safe to cook food directly on aluminum foil. Aluminum is a heavy metal that’s toxic and should not be allowed to accumulate in the human body.
There have been some studies[1] that show there is evidence that an accumulation of aluminum can be linked to Alzheimer’s.
As air fryers are a new type of appliance there have been no studies published as to whether using aluminum foil when air frying increases the risk of toxicity.
So while it is safe from a fire risk point of view, it might be worth considering a different way to cook certain foods. It might also be worth limiting just how many times per week you cook using aluminum foil.
Don’t Use Aluminum Foil With Acidic Foods
Acidic foods like tomatoes, citrus and vinegars have been known to cause a chemical reaction which allows aluminum to get into the food.
It’s fine to use foil to catch grease at the bottom of an oven-type air fryer, but you should never use aluminum foil if it will directly touch any acidic foods which includes many sauces and marinades.
Are There Any Alternatives To Foil That Can Be Used In An Air Fryer?

Let’s look at some of the alternatives to aluminum foil that can be used in an air fryer.
Foil Trays
Before we leave aluminum foil behind, we must mention foil trays. These aluminum foil trays are convenient as they are shaped in many cases to fit in the basket of the air fryer without the need to reshape etc.
However the same guidance should be followed when using foil trays. Which is that foil trays should not be used with any acidic foods. This includes lemons and other citrus, vinegars, Tomatoes, peppers, or any marinade or sauce containing any of the above.This doesn’t only go for when air frying – it also applies to oven baking too.
Baking Paper
- 300mm x 50m for professional catering use
- Perfect for pastry making and specialist confectioners
Baking paper is a great alternative to using aluminum foil. It can be used for baking, roasting and air frying.
From a safety point of view, baking paper has none of the risks associated with aluminum foil. It can be used with acidic foods as well as meats, vegetables etc.
Baking paper is also far more environmentally friendly than aluminum foil and works as a natural non-stick agent.
However, it is more likely to fly around unless it is weighted down properly. This is where those pastry weights offer a great, safe solution.
As with foil, be sure to leave as many holes in the basket unblocked as possible.

The Best Ways to Safely Use Aluminum Foil In The Air Fryer
We’ve covered so much in this article so let’s recap on the best ways to use tin foil in your air fryer.
- Never put foil directly on the element
Whichever type of air fryer you own you should never cover the element with anything. This could lead to fire or the breakdown of your appliance. - Allow the hot air to flow freely
In basket type air fryers you should never block all of the holes in the basket as this will lead to the food not cooking properly. - Never use aluminum foil with anything acidic
This includes; tomatoes, peppers, lemon juice (or any citrus fruit or juice), vinegars, wine or marinade and sauce containing anything acidic.
