How Air Fryers Work: Why Material Safety Matters
To understand which metals are safe for air fryer use, it helps to first understand how your appliance works. Unlike a conventional oven that heats air from the bottom and sides, an air fryer uses a powerful fan to circulate superheated air around your food at high speeds, typically reaching temperatures up to 400°F (204°C). This rapid air circulation is what gives air-fried food its signature crispy exterior without submerging it in oil.
The Role of the Heating Element and Fan
The heating element is located at the top of most air fryer units, just above the cooking basket. The fan pulls air up from the bottom of the unit, passes it over the heating element to heat it, then circulates the hot air down and around the food in the basket. This design means that any object placed in the air fryer must not block the airflow between the heating element, fan, and cooking basket, as this can cause overheating, uneven cooking, or even a fire.
Why Convection Cooking Changes Material Rules
Many people assume that air fryer material rules are the same as microwave rules, where most metal causes sparks and damage. This is a common misconception: air fryers use convection heating, not microwave radiation, so small, blunt metal objects will not cause sparks on their own. That said, the high-speed circulating air and concentrated heat do create unique safety requirements for metal cookware. Thin, reactive, or poorly secured metal can warp, leach harmful substances into food, or even catch fire if it comes into contact with the heating element. Understanding these unique conditions is key to using metal safely in your air fryer.
Types of Metal Cookware Safe for Air Fryers
Not all metal is safe for air fryer use, but several common types of metal cookware are not only safe but highly effective for air frying. Below are the most popular safe options, along with their pros, cons, and best use cases.
Stainless Steel: The Gold Standard
Food-grade stainless steel (typically 18/8 or 18/10, meaning it contains 18% chromium and 8-10% nickel) is the most popular and reliable metal for air fryer use. It is non-reactive, meaning it won’t leach metals or alter the flavor of acidic foods like tomatoes, citrus, or vinegar. It is also extremely durable, resistant to warping even at the highest air fryer temperatures, and easy to clean. Stainless steel works well for almost every air fryer recipe, from crispy roasted vegetables and french fries to baked goods and reheated leftovers. Look for stainless steel cookware that is labeled oven-safe, as this is a good indicator it can handle air fryer heat. Avoid thin, low-quality stainless steel, as it can warp over time with repeated high-heat use.
Cast Iron: Durable and Heat-Resistant
Cast iron is another excellent option for air fryer use, especially if you want to achieve a restaurant-quality sear on steaks, chops, or burgers. Cast iron holds heat extremely well, so it will keep food warm even after removing it from the air fryer, and it is completely non-reactive when properly seasoned. It is also ideal for baking items like cornbread, skillet cookies, or small batch breads. The only downsides to cast iron are its weight (make sure your air fryer can support the weight of the skillet without damaging the basket) and the fact that it heats up very quickly, so you may need to adjust cook times slightly to avoid overcooking. Avoid using soap to clean cast iron after air fryer use, as this can strip the seasoning; instead, wipe it out with a paper towel and rinse with hot water if needed.
Aluminum: What to Look For
Aluminum is a lightweight, even-heating metal that works well for air fryer baking, but you need to be careful about the type of aluminum you use. Uncoated, plain aluminum is reactive, meaning it will leach small amounts of aluminum into acidic foods and can cause off-flavors and discoloration. Anodized aluminum, on the other hand, has been treated to create a hard, non-reactive surface that is completely safe for air fryer use. Anodized aluminum trays and pans are great for baking cookies, cakes, and muffins in the air fryer, as they heat evenly and release food easily. Avoid any aluminum cookware that is scratched, dented, or showing signs of wear, as this can compromise the non-reactive coating.
Enameled Metal: Pros and Cons
Enameled metal cookware, such as enameled cast iron Dutch ovens, is a safe and versatile option for air fryer use. The enamel coating creates a non-reactive, non-stick surface that is easy to clean and won’t alter the flavor of acidic foods. Enameled Dutch ovens are perfect for braising meats, making stews, or cooking whole small chickens in the air fryer, as they hold heat well and distribute it evenly. The main downside of enameled metal is that the enamel coating can chip if you drop the cookware or use metal utensils on it, so handle it with care. Avoid using enameled cookware that has any chips or cracks, as the exposed metal underneath can react with food.
Types of Metal to NEVER Put in an Air Fryer
Just as there are safe metals for air fryer use, there are several types of metal that should never go in your appliance, as they can cause damage, health risks, or fire hazards. Avoid the following at all costs:
- Unsecured thin aluminum foil: While aluminum foil itself is not inherently dangerous, thin, unsecured foil can be blown around by the air fryer’s fan, potentially touching the heating element and causing a fire. If you do use foil, make sure it is weighted down by food and does not extend above the sides of the cooking basket.
- Metal with sharp, pointed edges: Sharp metal objects like bent wire racks, pointed forks, or bent skewers can cause arcing (sparks) if they get too close to the heating element. Even if they don’t cause sparks, sharp edges can scratch the interior of your air fryer or cut you when handling hot cookware.
- Uncoated reactive metals: Plain uncoated aluminum, copper, and other reactive metals will leach small amounts of metal into food, especially when cooking acidic dishes. This can lead to off-flavors, discoloration, and potential health risks with repeated use.
- Metal with flaking paint or non-stick coating: Cookware with chipping, flaking, or peeling coatings can release toxic fumes when heated to high temperatures, and the coating can contaminate your food. Avoid any metal cookware that shows signs of wear on its coating.
- Metal cookware with plastic or wooden handles not rated for high heat: Plastic and wood can melt or catch fire at air fryer temperatures, leading to a mess, damaged cookware, and even fire hazards. Only use metal cookware where all components, including handles, are rated for temperatures up to 400°F (204°C).
- Oversized metal trays that block airflow: Any metal cookware that is too large to fit comfortably in the air fryer basket with at least 1 inch of space around all sides will block the circulation of hot air. This leads to uneven cooking, overheating of the air fryer, and increased fire risk.

Step-by-Step Guide to Using Metal in Your Air Fryer Safely
Using metal in your air fryer is simple as long as you follow a few key steps to avoid damage or safety risks. Follow this guide to use metal cookware safely every time:
- Verify your metal cookware is air fryer-safe: First, confirm that your metal cookware is made of one of the safe materials listed above, has no damage, flaking coating, or plastic parts that are not rated for high heat, and fits inside your air fryer basket with at least 1 inch of space around all sides for proper airflow. If the cookware is labeled “oven-safe,” it is almost always safe for air fryer use as well.
- Prep your cookware and food: If you are using stainless steel or cast iron, you can lightly coat it with a thin layer of oil to prevent sticking, just as you would for conventional oven cooking. Avoid using aerosol cooking sprays, as they often contain propellants that can damage the interior coating of your air fryer; instead, use a silicone brush or paper towel to apply oil evenly. For other safe metals like anodized aluminum or enameled cast iron, oil is usually not necessary unless your recipe calls for it.
- Place the metal cookware in the air fryer basket: Center the cookware in the basket, making sure it does not touch the heating element at the top of the unit or the fan. Never place metal cookware directly on the heating element or the bottom of the air fryer cavity, as this can cause warping, melting, or fire. If you are using multiple metal items, make sure they are spaced apart to allow air to circulate freely around all sides.
- Set the temperature and cook time: Air fryers cook food much faster than conventional ovens, so you will typically need to reduce cook times by 10-20% compared to oven recipes. Start with the lower end of the cook time range and check your food halfway through to avoid overcooking. Most air fryers have preset programs for common foods like fries, chicken, and baked goods that you can use as a starting point.
- Remove cookware carefully: Metal cookware will get extremely hot in the air fryer, much hotter than it would in a conventional oven, due to the concentrated circulating hot air. Always use oven mitts or a heat-resistant glove when handling metal cookware from the air fryer, and never touch it with bare hands. Place the hot cookware on a heat-safe surface immediately after removing it from the air fryer.
- Clean up properly: Let the metal cookware cool completely before washing to avoid warping. For stainless steel and cast iron, use warm soapy water and a non-abrasive sponge to clean; avoid steel wool or harsh scrubbers that can scratch the surface. For enameled metal, use gentle cleaners and avoid abrasive tools that can chip the enamel. Wipe out the interior of your air fryer after each use to remove any food residue or oil splatters.
Common Mistakes to Avoid When Using Metal in an Air Fryer
Even experienced air fryer users make mistakes when using metal cookware. Avoid these common errors to keep your appliance and cookware in good condition and ensure safe, delicious results:
- Using unsecured aluminum foil: As mentioned earlier, thin aluminum foil that is not weighted down by food can be blown into the heating element by the air fryer’s fan, causing a fire. If you use foil to line your basket or cookware, make sure it is held down by food and does not extend above the top of the basket.
- Overfilling metal cookware: Packing food too tightly into metal trays or skillets blocks airflow, leading to soggy, unevenly cooked food, and can cause the air fryer to overheat. Leave space between food items to allow hot air to circulate freely.
- Using oversized metal cookware: Metal trays or skillets that are too large for your air fryer basket will block the airflow vents, leading to uneven cooking, overheating, and potentially triggering the air fryer’s safety shut-off or causing a fire. Always measure your cookware against your air fryer basket before purchasing to ensure it fits.
- Placing metal directly on the heating element: Never set metal cookware directly on the heating element at the top of the air fryer, as this can cause the metal to warp, melt, or catch fire. Always place metal inside the cooking basket, where it is designed to sit.
- Using damaged metal cookware: Dented, cracked, or flaking metal cookware can leach harmful substances into food, break during cooking, and damage the interior of your air fryer. Inspect your metal cookware regularly for signs of damage, and replace it if you notice any issues.
- Forgetting that metal heats up faster in an air fryer: The concentrated circulating hot air in an air fryer causes metal to heat up much faster than in a conventional oven. Always use oven mitts when handling metal cookware from the air fryer, and never leave hot metal cookware unattended on a heat-sensitive surface.
Tips and Best Practices for Metal Air Fryer Use
Follow these tips to get the most out of using metal in your air fryer, while keeping your appliance and cookware in great condition:
- Invest in high-quality, oven-safe metal cookware: Cheap, thin metal trays can warp at high temperatures, leading to uneven cooking and potential damage to your air fryer. Look for cookware that is explicitly labeled oven-safe, as this indicates it can handle temperatures up to at least 400°F (204°C), the maximum temperature of most air fryers.
- Preheat metal cookware for better results: For recipes that require a crispy exterior, like seared steak or roasted potatoes, preheat your stainless steel or cast iron cookware in the air fryer for 2-3 minutes before adding food. This will help create a crispier crust and prevent sticking.
- Use blunt metal utensils: Sharp metal forks, knives, or utensils can scratch the surface of your metal cookware, and can also cause arcing if they get too close to the heating element. Use silicone, wooden, or blunt metal utensils to avoid damage and safety risks.
- Avoid metal cookware with non-stick coatings unless rated for high heat: Many low-quality non-stick coatings break down at temperatures above 350°F, releasing toxic fumes. If you use non-stick metal cookware in your air fryer, make sure it is explicitly rated for temperatures up to 400°F.
- Clean your air fryer and cookware regularly: Built-up food residue and oil splatters can cause smoke, bad flavors, and even fire hazards. Wipe out the interior of your air fryer after each use, and wash metal cookware thoroughly after each use to avoid buildup.
- Test small batches first: If you are trying a new type of metal cookware or a new recipe, start with a small batch to ensure it works well with your air fryer, doesn’t cause any issues, and gives you the results you want. This will help you avoid wasting food or damaging your cookware.
Frequently Asked Questions
Can you put metal in an air fryer without it sparking?
Yes, as long as the metal is food-grade, has no sharp pointed edges, and is placed correctly in the basket away from the heating element. Sparks only occur if metal is too close to the heating element, or has sharp points that cause arcing. Blunt, safe metal cookware will not spark when used properly.
Is aluminum foil safe to use in an air fryer?
Yes, aluminum foil is safe to use in an air fryer as long as it is secured by food so it does not blow around, and does not touch the heating element. Avoid using thin, unsecured foil, as it can be caught by the fan and cause a fire. Never cover the entire bottom of the air fryer basket with foil, as this will block airflow.
Can you put metal trays in an air fryer?
Yes, metal trays are safe to use in an air fryer as long as they are made of safe metal (stainless steel, cast iron, or anodized aluminum), fit inside the basket with space for airflow, and have no plastic parts that cannot handle high heat. Metal trays are great for making cookies, roasted vegetables, or small batch meals.
Why does my metal cookware get so hot in the air fryer?
Air fryers circulate hot air directly around food at high speeds, so metal cookware heats up much faster and hotter than it would in a conventional oven. This is normal, and you should always use oven mitts when handling metal cookware from the air fryer to avoid burns.
Can I use metal skewers in an air fryer?
