Metal cookware and utensils are safe in most air fryers, but the type of metal and how you use it matters

Metal pans, racks, and skewers work in air fryers because the heating element is not a microwave—it uses convection heat, the same way a conventional oven does. However, not all metal is equal. Thin aluminum foil can tear and block airflow. Stainless steel and cast iron are generally safe. The real risk is not the metal itself but loose pieces, improper placement, or using metal that conducts heat unevenly and damages the appliance's interior.

The confusion often comes from microwave safety rules, where metal reflects radiation and causes arcing. Air fryers have no such mechanism. What you need to watch for instead is whether the metal piece can move around, touch the heating element, or prevent hot air from circulating—the three things that actually cause problems.

Key Takeaways

  • Stainless steel and cast iron cookware are safe in air fryers and conduct heat evenly.
  • Aluminum foil is safe but must be weighted down, perforated on top to allow airflow, and kept away from the heating element.
  • Metal utensils like tongs and skewers are safe to use while cooking, but remove them before the cycle ends if they are not heat-resistant.
  • Avoid thin, flimsy metal that can vibrate loose, touch the heating coil, or block the air vents inside the basket.
  • Always check your air fryer's manual, as some models have specific restrictions on metal placement or size.

Stainless steel and cast iron pans work well in air fryers

Stainless steel pans and baking sheets are among the safest metal options for air fryers. They conduct heat evenly, do not react with food, and are rigid enough to stay in place. Many air fryer owners use stainless steel baskets or racks to expand cooking capacity or to separate foods. As long as the pan fits inside the basket with at least half an inch of clearance on all sides, it will not interfere with airflow.

Cast iron is also safe and actually performs well in air fryers because it retains and distributes heat evenly. A cast iron skillet or small Dutch oven can go directly into the basket. The main consideration is weight—cast iron is heavy, so make sure your air fryer's basket can support it without sagging or touching the heating element above. Preheat the cast iron for a few minutes before adding food, just as you would in a regular oven.

Aluminum foil requires three precautions to use safely

Aluminum foil is safe in air fryers, but it must be used correctly. The three rules are: weight it down, perforate the top, and keep it away from the heating element. Foil that is not secured will flap around, block airflow, and potentially touch the coil. Foil with no holes on top will trap steam and create uneven cooking or cause the foil to puff up and shift.

To use foil safely, line the bottom of the basket with a single layer, then place your food on top or wrap the food itself. Use a fork or knife to poke small holes across the top surface—this lets hot air circulate and steam escape. Make sure the foil does not extend up the sides of the basket or curl toward the heating element. If you are wrapping individual items like fish or vegetables, keep the foil packet flat and low in the basket, away from the top coil.

Parchment paper is often a safer alternative to foil because it is lighter and less likely to shift. Both foil and parchment should be weighted down with food or held in place by the weight of what you are cooking.

Metal utensils are safe to use while cooking

Metal tongs, spatulas, skewers, and forks are safe to use inside the air fryer while food is cooking. You can flip items, rearrange them, or check doneness without worry. The metal utensil itself will not cause arcing or damage because air fryers use convection heat, not radiation.

The only caution is heat transfer. Metal utensils left in the basket for the entire cycle will become very hot. If you use a metal skewer or fork to check food, remove it before the cooking time ends, or use a utensil with a heat-resistant handle. Stainless steel handles stay cooler than bare metal, so they are a better choice for longer cooking times.

What to avoid: loose metal and improper placement

The real dangers come from metal that is not secured or positioned correctly. Thin, flimsy metal—like cheap aluminum pans or crumpled foil—can vibrate loose during the cooking cycle and shift into the heating element or block the air vents. This can damage the coil, scorch food, or cause uneven cooking.

Never place metal directly against the heating element or the walls of the basket where it can touch the coil. Always leave clearance. If you are using a metal rack or divider, make sure it is designed for air fryer use and sits flat and stable in the basket. Homemade metal inserts or bent wire racks can shift and cause problems.

Also avoid metal with sharp edges or burrs that could scratch the non-stick coating inside the basket. A small scratch usually does not affect safety, but it can spread over time and make the basket harder to clean.

Check your air fryer manual for brand-specific rules

Some air fryer models have specific restrictions on metal use. A few manufacturers recommend against any metal except their own accessories, while others are more permissive. Your manual will tell you the maximum size of cookware, whether metal racks are included or sold separately, and any materials to avoid.

If your manual says metal is not recommended, it is usually because the model has a smaller interior or a heating element positioned in a way that makes metal placement risky. In those cases, silicone or ceramic bakeware may be safer choices. If you have lost your manual, check the manufacturer's website or contact customer service—they can tell you what metal cookware is safe for your specific model.

Frequently Asked Questions

Can metal touch the heating element in an air fryer?

No. Metal touching the coil can damage the element, scorch food, or create a fire hazard. Always keep at least half an inch of clearance between any metal and the heating element. If a pan or foil shifts during cooking, stop the cycle and reposition it before continuing.

Is it safe to use metal skewers in an air fryer?

Yes, metal skewers are safe and useful for cooking kebabs or holding food in place. Make sure the skewers fit inside the basket without touching the sides or top coil. Remove them before the cycle ends if they do not have heat-resistant handles, as they will become very hot.

Can I use a metal baking sheet instead of the air fryer basket?

Yes, if it fits. The sheet must be smaller than the basket interior with at least half an inch of clearance on all sides to allow air to flow underneath and around the food. Perforated metal sheets work better than solid ones because they let more hot air reach the bottom of the food.

What happens if aluminum foil comes loose during cooking?

Loose foil can block air vents, touch the heating element, or wrap around food unevenly, causing burnt spots or undercooked areas. Stop the air fryer when ready, remove the foil, and reposition it securely. Weight it down with food or use parchment paper instead.

Is stainless steel safer than aluminum in an air fryer?

Both are safe if used correctly. Stainless steel is more rigid and less likely to shift, making it slightly easier to use. Aluminum foil is thinner and requires more care to find, but it is safe when weighted down and perforated. Choose based on what you are cooking and how much airflow you need.
