Can Aluminium Foil Go in the Air Fryer? Safe Cooking Tips You Need to Know

Air fryers have quickly become a kitchen favorite for their ability to deliver crispy, golden-brown food with minimal oil. From French fries to chicken wings, the convenience is hard to beat. But as we get more creative with our air frying, one question keeps popping up: can aluminium foil go in the air fryer?

Maybe you’ve seen a viral TikTok hack where someone lines their air fryer basket with foil to make cleanup easier. Or perhaps you’re trying to cook a delicate fish fillet and want to prevent it from sticking. It’s tempting to use aluminium foil—after all, we’ve used it in ovens and grills for years. But air fryers work differently. They rely on rapid, circulating hot air to cook food evenly. So, is using foil safe, or could it cause problems?

How Air Fryers Work and Why Foil Use Is a Hot Topic

To understand whether aluminium foil is safe in an air fryer, it helps to know how these appliances work. Unlike traditional ovens that rely on radiant heat, air fryers use a powerful fan to circulate hot air at high speeds around your food. This creates that coveted crispy exterior without deep frying.

The key to success? Unimpeded airflow. When air can’t move freely, your food won’t cook evenly. This is where foil comes into question. If you block the airflow, you risk undercooked spots, longer cooking times, and even appliance damage.

Airflow Matters More Than You Think

Imagine trying to blow through a straw that’s half-covered. That’s what happens when you cover your air fryer basket with foil. The fan struggles to push air around, reducing efficiency. In my own experience, I once tried to roast potatoes in a fully lined basket. The result? Soggy on the bottom, dry on top—and the cook time doubled.

Air fryer manufacturers often emphasize keeping the basket as open as possible. For example, Philips, a leading brand, states in their user manuals that blocking airflow can lead to uneven cooking and overheating.

Heat Distribution and Foil’s Reflective Properties

Aluminium foil is highly reflective. It doesn’t absorb heat like food does—it reflects it. This can create hot and cold spots in your air fryer. Think of it like wearing a mirror in the sun: light bounces off, not in. When foil covers large areas, it can prevent heat from reaching certain parts of your food.

For instance, if you wrap a chicken breast completely in foil, the outside might cook slower because the foil reflects heat away. This is why some recipes suggest only partially covering food or using foil in specific ways.

The Risk of Sparks and Electrical Issues

Here’s a lesser-known but serious concern: arcing. If aluminium foil touches the heating element or the metal parts of the air fryer basket, it can cause sparks. This happens because the foil becomes electrically charged by the heating coil.

I once saw a friend’s air fryer spark like a Fourth of July firework because a small piece of foil had curled up and touched the element. No damage occurred, but the smell of burnt metal was enough to make us swear off full-basket lining for good.

While modern air fryers have safety features, repeated arcing can damage internal components over time. Always ensure foil stays at least 1–2 inches away from the heating element and basket walls.

When Is It Safe to Use Aluminium Foil in an Air Fryer?

Good news: you don’t have to ditch foil entirely. When used correctly, it can be a helpful tool. The key is moderation and placement. Let’s break down the safe ways to use aluminium foil.

Use Foil for Small, Delicate Items

Foil shines when you need to protect fragile foods from breaking apart or drying out. For example:

• Fish fillets: Place a small sheet of foil under the fish to prevent sticking and tearing.
• Vegetables: Wrap asparagus or green beans in a loose foil “boat” to keep them from falling through the basket.
• Stuffed mushrooms: Use foil to hold the filling in place while allowing steam to escape.

Tip: Crimp the edges slightly to create a shallow tray, but don’t cover the top. Let the air circulate freely over the food.

Line the Bottom for Easy Cleanup (With Caution)

Many people use foil to catch drips and make cleanup easier. This is okay if done right:

1. Cut a piece of foil to fit the bottom of the basket, leaving the sides exposed.
2. Do not cover the entire basket or block the air vents.
3. Ensure the foil doesn’t touch the heating element.

I do this when cooking fatty meats like bacon or sausages. The foil catches the grease, and I just toss it after. Just remember: the food should still sit on the basket’s grill, not directly on the foil.

Create Foil Packets for Even Cooking

Foil packets are a game-changer for veggies, fish, or chicken. They trap steam while letting heat circulate around the edges. For example, I love making lemon-garlic salmon in a foil packet:

• Place the salmon on a foil sheet with lemon slices, garlic, and herbs.
• Fold the edges to create a loose tent—don’t seal it tight.
• Cook at 375°F (190°C) for 12–15 minutes.

The result? Juicy, flavorful fish with no sticking. The open top allows the air to crisp the top layer while the foil keeps the bottom moist.

Avoid These Common Foil Mistakes

Even with good intentions, it’s easy to go wrong. Here’s what not to do:

• ❌ Don’t fully line the basket: Blocks airflow and causes uneven cooking.
• ❌ Don’t let foil touch the heating element: Sparks and damage can occur.
• ❌ Don’t use crumpled or sharp-edged foil: Can scratch non-stick coatings or create hot spots.
• ❌ Don’t seal foil packets too tightly: Steam needs to escape to prevent soggy food.

Pro tip: Use heavy-duty foil for better durability and less tearing. It’s less likely to shift during cooking.

Alternatives to Aluminium Foil: Are They Better?

If you’re unsure about foil or want a safer option, there are great alternatives. Each has pros and cons, depending on what you’re cooking.

Silicone Mats and Liners

Silicone mats are reusable, non-stick, and heat-resistant up to 450°F (230°C). They’re perfect for:

• Preventing sticking (great for cookies or fish).
• Catching drips without blocking airflow.
• Being eco-friendly (no waste).

I keep a set of silicone liners in my kitchen. They’re easy to wash, don’t scratch the basket, and work well for most foods. The only downside? They can’t be used for high-heat searing (above 400°F).

Reusable Silicone Pouches

These are like foil packets but made from food-grade silicone. They’re ideal for:

• Steaming veggies or fish.
• Infusing flavors (add herbs, butter, or wine).
• Reducing single-use waste.

One brand I tried, Stasher, works great in air fryers. Just make sure to open the top slightly for airflow.

Air Fryer Parchment Paper

Parchment paper is another excellent option. It’s:

• Non-stick and heat-safe.
• Great for baking (cookies, pastries).
• Biodegradable and compostable.

But be careful: parchment can block airflow if it covers too much of the basket. Use pre-cut rounds with holes or cut your own to match the basket’s design.

When to Stick with Foil

Despite the alternatives, foil still has its place. It’s:

• Cheaper (especially if you already have it).
• Versatile (can be shaped for any food).
• Heat-resistant (up to 1200°F, though air fryers rarely go above 400°F).

For high-heat roasting or when you need a custom shape, foil is hard to beat. Just use it wisely.

Step-by-Step Guide: How to Safely Use Foil in Your Air Fryer

Ready to try foil? Follow these steps to do it right every time.

Step 1: Choose the Right Foil

Use heavy-duty aluminium foil (0.024 mm thick or higher). Regular foil tears easily, especially with sharp foods like chicken wings. Heavy-duty foil holds its shape better and is less likely to shift during cooking.

Step 2: Cut and Shape the Foil

• For a bottom liner: Cut a piece to fit the basket’s base, leaving 1 inch of space around the edges.
• For a packet: Use a large sheet (12×12 inches) to wrap food loosely.
• For a boat: Fold up the edges to create a shallow tray.

Tip: Lightly oil the foil before adding food to prevent sticking.

Step 3: Position the Foil Correctly

Place the foil in the basket, but never let it:

• Touch the heating element (usually at the top).
• Cover more than 50% of the basket’s surface.
• Block the air vents (check your model’s manual).

I always do a quick visual check: if I can’t see the grill lines under the foil, it’s too much.

Step 4: Add Your Food

Place food on top, ensuring it’s not touching the foil’s edges. For packets, leave the top open or fold it loosely. For boats, keep the sides low so air can flow over.

Step 5: Monitor and Adjust

Check halfway through cooking. If the food looks undercooked, you may need to:

• Remove the foil to increase airflow.
• Flip the food for even browning.
• Adjust the time or temperature.

For example, I once cooked chicken thighs with foil under them. At 10 minutes, I removed the foil and increased the temp to 400°F (200°C) to crisp the skin.

Step 6: Clean Up

Let the basket cool, then remove the foil. Wipe the basket with a damp cloth. If there are stubborn bits, soak it in warm, soapy water.

Real-Life Examples: Foil Successes and Failures

Let’s look at some practical examples to illustrate what works—and what doesn’t.

Success: Crispy Bacon with Minimal Grease

Method: I lined the basket’s bottom with foil, leaving the sides open. Added bacon strips directly on the grill. Cooked at 390°F (199°C) for 10 minutes.

Result: Crispy bacon, easy cleanup. The foil caught all the grease, and the air flowed freely.

Failure: Soggy Chicken Wings

Method: I fully lined the basket with foil, then added wings. Cooked at 380°F (193°C) for 20 minutes.

Result: Wings were steamed, not crispy. The foil blocked airflow, and the basket overheated. Lesson learned: never cover the entire basket.

Success: Lemon-Herb Salmon in a Foil Packet

Method: Placed salmon on foil with lemon, herbs, and a drizzle of olive oil. Folded edges loosely. Cooked at 375°F (190°C) for 12 minutes.

Result: Perfectly cooked salmon—moist inside, lightly crisped on top. No sticking, no mess.

Failure: Burnt Foil and Smell

Method: I used a small crumpled ball of foil to prop up a chicken breast. The foil touched the heating element.

Result: Sparks, a burnt smell, and a damaged basket coating. Now I use a silicone trivet instead.
