Understanding Air Fryer Materials and Safety
Before we answer the question “Can I put metal in air fryer?” directly, it helps to understand how an air fryer works. An air fryer is essentially a small convection oven. It uses a heating element and a powerful fan to circulate hot air around your food at high speed. This rapid air movement cooks food quickly and creates a crispy exterior similar to deep frying, but with far less oil.
The basket or tray inside your air fryer is typically made of a non-stick coated metal, usually aluminum or steel with a PTFE or ceramic coating. The heating element is located at the top of the appliance, and the fan sits right behind it. This setup means that anything you put inside must be able to withstand intense heat and also allow air to circulate freely.
Here’s why material choice matters:
- Heat conductivity: Some metals heat up faster than others, which can lead to uneven cooking or burning.
- Reactivity: Certain metals can react with acidic foods, affecting taste and safety.
- Reflectivity: Shiny metal surfaces can reflect heat, potentially interfering with the cooking process or even damaging the heating element.
- Airflow obstruction: The wrong shape or placement of metal can block the hot air from circulating properly.
When you understand these factors, the question “Can I put metal in air fryer?” becomes less about a simple yes or no and more about knowing which metal, in what form, and under what conditions.
Can I Put Metal in Air Fryer? The Short Answer
Yes, you can put metal in an air fryer, but only certain types of metal and only under specific conditions. The full answer is more nuanced. Some metal containers and utensils are perfectly safe, while others can damage your air fryer or even create a fire hazard.
Here’s the quick breakdown:
- Safe metals: Stainless steel, aluminum (in certain forms), and cast iron (in moderation).
- Unsafe metals: Thin aluminum foil used improperly, copper, and non-stick metal pans with damaged coatings.
- Conditional: Metal bakeware and pans are safe only if they fit properly and do not block airflow.
The key is to understand that the air fryer basket itself is made of metal. So the question “Can I put metal in air fryer?” is almost always answered with “yes” when it comes to the basket and any included accessories. The real question is about additional metal items you might want to use inside your air fryer.
Types of Metal and Their Suitability
Not all metals are created equal when it comes to air frying. Let’s look at the most common types of metal you might be tempted to use and how they perform in an air fryer.
| Metal Type | Safe to Use? | Best Use Case | Key Considerations |
|---|---|---|---|
| Stainless Steel | Yes | Pans, bowls, utensils, racks | Heat-resistant, non-reactive, durable. Ensure it fits without blocking airflow. |
| Aluminum (heavy-duty) | Yes | Baking pans, foil pressed into a dish shape | Use only heavy-duty foil. Avoid thin foil touching the heating element. |
| Aluminum Foil (thin) | Conditional | Lining baskets, wrapping food | Do not cover the entire basket. Keep foil away from the heating element. Never use foil in the bottom of the air fryer. |
| Cast Iron | Yes | Small skillets, baking dishes | Very heavy. Preheating is required. Can scratch non-stick coatings. Use enameled cast iron for best results. |
| Copper | No | Not recommended | Highly reactive, can damage the heating element, and may cause sparking. |
| Non-Stick Coated Metal | Conditional | Accessories designed for air fryers | Only use if the coating is intact and the item is rated for high heat (450°F or higher). |
| Carbon Steel | Yes | Pans, woks | Similar to cast iron but lighter. Seasoning may be affected by high heat. |
When you’re wondering “Can I put metal in air fryer?” refer to this table first. If your metal item isn’t on the safe list, it’s better to leave it out.
When Metal Is Safe to Use in an Air Fryer
Knowing the answer to “Can I put metal in air fryer?” is only half the battle. You also need to know when it’s safe to do so. Here are the conditions that make using metal in your air fryer a good idea.
Proper Fit and Airflow
The most important factor is that your metal pan, bowl, or rack must fit inside the basket without touching the heating element. There should be at least an inch of space around all sides to allow hot air to circulate. If the metal item is too large, it will block the airflow, leading to uneven cooking and potentially overheating the appliance.
Heat Resistance
Any metal you use must be rated for temperatures of at least 400°F (204°C), and ideally 450°F (232°C) or higher. Most air fryers reach maximum temperatures around 400°F, but some models go up to 450°F. Stainless steel, cast iron, and heavy-duty aluminum all handle these temperatures with ease.
Food Compatibility
Some metals react with acidic foods like tomatoes, citrus, or vinegar. Stainless steel and enameled cast iron are non-reactive, so they’re safe for all types of food. Bare aluminum can react with acidic ingredients, causing a metallic taste and discoloration. If you’re cooking something acidic, use stainless steel or enameled cookware instead.
Manufacturer Guidelines
Always check your air fryer’s manual. Some manufacturers explicitly state that metal pans or accessories are not allowed. Others provide a list of approved materials. If your manual says “no metal,” then the answer to “Can I put metal in air fryer?” is a firm no for that specific model.
When Metal Is Dangerous in an Air Fryer
There are situations where putting metal in your air fryer is not just a bad idea, it’s genuinely dangerous. Here’s what to watch out for.
Metal Touching the Heating Element
This is the number one risk. If a metal pan, foil, or utensil touches the exposed heating element, it can cause a short circuit, sparking, or even a fire. The heating element gets extremely hot, and metal conducts electricity. Never let any metal item come into contact with the heating element.
Thin or Flimsy Metal
Thin aluminum foil, disposable aluminum pans, and thin metal bakeware can warp or melt under the high heat of an air fryer. When metal warps, it can shift position and touch the heating element. Disposable pans are especially risky because they’re not designed for the intense airflow and heat of an air fryer.
Metal with Sharp Edges
Metal pans or utensils with sharp edges can scratch the non-stick coating of your air fryer basket. Once the coating is scratched, it can flake off into your food and the basket will no longer be non-stick. Scratched coatings can also harbor bacteria and are harder to clean.
Copper and Reactive Metals
Copper is an excellent conductor of heat and electricity, but that’s exactly why it’s dangerous in an air fryer. Copper can cause sparking if it touches the heating element, and it reacts with many foods. Avoid copper cookware entirely in your air fryer.
Metal Lids or Covers
Never put a metal lid on a container inside an air fryer. The lid can trap steam and pressure, potentially causing the container to explode. Additionally, the lid can block airflow and may warp or damage the heating element. If you need to cover food, use a silicone lid or a piece of foil with a vent.
Step-by-Step Guide: How to Safely Use Metal in an Air Fryer
If you’ve decided that the answer to “Can I put metal in air fryer?” is yes for your specific situation, follow these steps to do it safely.
Step 1: Check Your Air Fryer Manual
Before you do anything, read the manufacturer’s instructions. Some models explicitly forbid metal pans or accessories. If your manual says no, don’t risk it.
Step 2: Choose the Right Metal Item
Select a metal pan, bowl, or rack that is:
- Made of stainless steel, heavy-duty aluminum, or enameled cast iron.
- Free of sharp edges, rust, or damage.
- Small enough to fit inside the basket with at least 1 inch of space on all sides.
Step 3: Preheat the Air Fryer (Optional but Recommended)
Preheating helps the metal item reach cooking temperature more evenly. If you’re using cast iron or a thick stainless steel pan, preheating is especially important to prevent hot spots.
Step 4: Place the Metal Item Carefully
Set the metal pan or rack inside the basket. Make sure it sits flat and does not wobble. Ensure it does not touch the sides, top, or bottom of the air fryer. If it touches any part of the appliance, remove it and find a smaller item.
Step 5: Add Food and Cook
Add your food to the metal container. Do not overfill it. Leave space for air to circulate around the food. Set the temperature and time according to your recipe.
Step 6: Monitor the Cooking Process
Check on your food halfway through cooking. Use a silicone or wooden utensil to stir or flip the food. Avoid metal utensils that could scratch the basket or the metal pan.
Step 7: Remove the Metal Item Safely
Use oven mitts or silicone gloves to remove the metal container from the air fryer. Metal gets extremely hot, and the handle will be too hot to touch bare-handed. Set the container on a heat-safe surface to cool.
Step 8: Clean Thoroughly
Wash the metal item by hand with warm soapy water. Avoid abrasive scrubbers that can scratch the surface. Dry completely before storing.
Aluminum Foil: The Most Common Metal Question
When people ask “Can I put metal in air fryer?” they’re often thinking about aluminum foil. It’s the most common metal item people want to use, and it’s also the most misunderstood.
Can You Use Aluminum Foil in an Air Fryer?
Yes, but with strict rules. Aluminum foil can be used in an air fryer, but only in certain ways. Here’s what you need to know.
Safe Ways to Use Aluminum Foil
- Lining the basket: You can line the bottom of the basket with foil to catch drips, but only if you leave the edges open for airflow. Never cover the entire bottom of the basket.
- Wrapping food: You can wrap food in foil, similar to cooking en papillote. Make sure the foil packet is sealed tightly and placed in the center of the basket.
- Creating a makeshift tray: You can fold heavy-duty foil into a small tray or dish shape to hold food. Keep it small and ensure it doesn’t touch the heating element.
Unsafe Ways to Use Aluminum Foil
- Covering the entire basket: If you cover the entire bottom of the basket with foil, you block the airflow. Hot air needs to circulate around the food to cook it properly. Blocking the airflow can also cause the air fryer to overheat.
- Foil touching the heating element: This is a fire hazard. The foil can melt or ignite if it touches the heating element.
- Using thin foil: Thin foil can tear easily and may be blown around by the fan. Pieces of foil can get stuck in the heating element or fan, causing damage.
- Foil in the bottom of the air fryer: Never put foil directly on the bottom of the air fryer (under the basket). The foil can block airflow and cause overheating.
Best Practices for Using Foil
- Use heavy-duty aluminum foil only.
- Keep foil pieces small and lightweight.
- Never let foil touch the heating element.
- Do not cover more than half of the basket’s bottom with foil.
- Weigh down the foil with food so it doesn’t blow around.
Stainless Steel and Cast Iron in Air Fryers
Two of the most common metal cookware materials are stainless steel and cast iron. Here’s how they perform in an air fryer.
Stainless Steel
Stainless steel is one of the best answers to “Can I put metal in air fryer?” It’s durable, non-reactive, and heat-resistant. Stainless steel pans, bowls, and racks are excellent for air frying.

Common Mistakes to Avoid
Even experienced cooks make mistakes when using metal in an air fryer. Here are the most common errors and how to avoid them.
Using a Metal Pan That’s Too Large
This is the most frequent mistake. A large metal pan blocks the airflow, leading to uneven cooking and potential overheating. Always measure your basket before inserting a metal pan.
Forgetting to Preheat
Metal pans, especially cast iron and stainless steel, need to preheat to cook evenly. If you add cold food to a cold pan in a cold air fryer, you’ll get uneven results.
Using Metal Utensils
Even if you’re using a metal pan, don’t use metal utensils to stir or flip your food. The metal can scratch the non-stick coating of the basket or the pan itself. Stick to silicone, wood, or nylon utensils.
Ignoring Manufacturer Warnings
Some air fryer models explicitly state that metal pans or accessories are not allowed. Ignoring these warnings can void your warranty and damage your appliance.
Putting Metal in a Preheated Air Fryer Without Care
If you add a cold metal pan to a hot air fryer, you risk thermal shock. This can warp the pan or even crack it. Always add metal items to the basket before preheating, or let them come to room temperature first.
Using Damaged Metal Items
Rusty, bent, or scratched metal pans are not safe. Rust can contaminate your food, and bent pans can wobble and touch the heating element. Inspect your metal items regularly and replace them if they show signs of damage.
Tips and Best Practices
Now that you know the answer to “Can I put metal in air fryer?” and how to use it safely, here are some expert tips to get the best results.
Choose the Right Size
Always use a metal pan that is smaller than your air fryer basket. A good rule of thumb is to leave at least 1 inch of space on all sides and 2 inches of space above the food. This ensures proper airflow and even cooking.
Use a Trivet or Rack
If you’re using a metal pan that doesn’t have a raised bottom, place it on a metal rack inside the basket. This lifts the pan off the bottom and allows hot air to circulate underneath, promoting even cooking.
Season Metal Pans Properly
For cast iron and carbon steel, proper seasoning is essential. Seasoning creates a non-stick layer and prevents rust. If you’re using a seasoned pan in an air fryer, make sure the seasoning is intact before cooking.
Clean Metal Items Immediately
Metal pans can stain or develop odors if left dirty. Clean them with warm soapy water immediately after use. For stubborn residue, use a paste of baking soda and water.
Experiment with Recipes
Once you’re comfortable with using metal in your air fryer, try recipes that benefit from metal cookware. Steaks, roasted vegetables, and baked goods like cornbread or brownies all turn out well in metal pans.
Keep a Spare Basket
If you use metal pans frequently, consider buying a spare air fryer basket. This way, you can use one basket for metal pans and keep the other one pristine for non-stick cooking.
