Can You Put Metal in an Air Fryer? A Comprehensive Guide to Safe Cooking

Air fryers have become a kitchen staple for many, offering a healthier way to enjoy crispy, delicious meals with minimal oil. But as you experiment with your air fryer, you might find yourself wondering: Can I put metal in it? The question often arises because we’re conditioned to avoid metal in microwaves, but air fryers work differently. Let’s dive into the details of using metal in an air fryer, exploring how these appliances function, which metals are safe, and what precautions you need to take to ensure safe and effective cooking.

How Air Fryers Work: The Key to Understanding Metal Safety

To answer whether metal is safe in an air fryer, it’s helpful to understand how these devices operate. Unlike microwaves, which use electromagnetic waves that can cause sparks when metal is involved, air fryers are essentially mini convection ovens. They rely on a heating element and a powerful fan to circulate hot air, typically between 200°F and 400°F, around the food. This rapid air circulation mimics the crispy results of deep frying without the oil.

Because air fryers don’t use radiation or electromagnetic fields, metal doesn’t pose the same risks as it does in a microwave. Instead, the main concerns are heat resistance, airflow, and the integrity of the air fryer’s nonstick coating. With this in mind, the short answer is yes, you can use metal in an air fryer—but only if it’s the right kind and used correctly.

Which Metals Are Safe for Air Fryers?

Not all metals are created equal when it comes to air fryer use. Here’s a breakdown of the types of metal cookware that are generally safe, along with some important considerations:

• Stainless Steel: Stainless steel pans, bowls, and skewers are excellent choices for air fryers. They’re durable, non-reactive, and can handle high temperatures without warping or releasing harmful substances. For example, a small stainless steel baking pan is perfect for making deep-dish pizza or reheating leftovers.
• Cast Iron: Cast iron skillets are another safe option, prized for their heat retention and ability to create a crispy sear. However, they take longer to heat up, so you may need to adjust cooking times. A small cast iron pan can be ideal for one-pan meals like cornbread or a small casserole.
• Aluminum: Oven-safe aluminum pans or trays can withstand the high temperatures of an air fryer, often up to 1220°F, which is well above the typical air fryer range. Aluminum is lightweight and conducts heat well, making it a popular choice for baking or roasting. Aluminum foil is also safe, but more on that later.

Always check that your metal cookware is labeled “oven-safe,” as this ensures it can handle temperatures up to at least 500°F without issues. If there’s no label, it’s better to err on the side of caution and avoid using it.

Metals and Materials to Avoid

While many metals are safe, some should never go in your air fryer due to safety or performance concerns:

• Nonstick-Coated Metal: Nonstick coatings, like Teflon, can break down under high heat, potentially releasing toxic fumes or flaking into your food. Stick to bare stainless steel, cast iron, or aluminum.
• Painted Metal: Decorative or painted metal cookware, unless coated with FDA-approved enamel (common on cast iron), can release toxic gases when heated. Avoid these to keep your food safe.
• Metal with Plastic or Wooden Handles: Plastic can melt, and wood can burn or pose a fire risk. Only use metal cookware with oven-safe handles, like silicone or metal, or use heat-resistant gloves when handling.
• Thin or Lightweight Metal: Disposable aluminum pans or very thin metal containers can get tossed around by the air fryer’s powerful fan, potentially damaging the appliance or disrupting cooking. If you use lightweight metal, weigh it down with food to keep it stable.
• Lead, Pewter, or Zinc-Containing Metals: These metals can leach toxins into food when heated, so avoid cookware made from these materials altogether.

Using Aluminum Foil in an Air Fryer

Aluminum foil is a popular choice for lining air fryer baskets to simplify cleanup, and it’s generally safe if used correctly. Here are some tips to ensure safe use, as recommended by sources like Food Network:

• Don’t Block Airflow: Place foil only in the basket where the food sits, not on the bottom of the air fryer where it could obstruct the heating element or fan. Too much foil can reduce air circulation, leading to uneven cooking.
• Weigh It Down: Always place food on top of the foil to prevent it from being sucked into the heating element, which could cause burning or damage.
• Avoid Acidic Foods: Acidic ingredients, like tomatoes or citrus, can react with aluminum foil, potentially causing small amounts of metal to leach into your food. Use parchment paper instead for these recipes.
• Check Manufacturer Guidelines: Some brands, like Philips, advise against using foil, while others, like Frigidaire, approve it for the basket only. Always consult your air fryer’s manual.

Foil is particularly useful for sticky or saucy foods, like chicken wings, or delicate items, like fish, that might stick to the basket. It can also be a lifesaver for reheating leftovers or cooking foil-pack meals, as long as you leave an opening at the top to avoid steaming instead of frying.

Protecting Your Air Fryer’s Nonstick Coating

Many air fryer baskets have a nonstick coating, which can be damaged by metal utensils. Using metal tongs, forks, or spoons to flip or remove food can scratch the coating, reducing its effectiveness and potentially releasing harmful particles into your food. Instead, opt for silicone or wooden utensils, as suggested by The Takeout. Similarly, avoid abrasive scrubbers when cleaning your air fryer—use a soft sponge and warm soapy water to preserve the coating.

Practical Tips for Using Metal in Your Air Fryer

Ready to use metal cookware in your air fryer? Here are some practical tips to ensure success:

• Check the Fit: Air fryer baskets are small, so make sure your metal pan or tray fits without touching the heating element or restricting airflow. A tight fit can lead to uneven cooking or damage to the appliance.
• Use Parchment for Baking: For baked goods like cakes or muffins, consider lining metal pans with parchment paper to prevent sticking and make cleanup easier. Just ensure the parchment doesn’t block airflow.
• Adjust Cooking Times: Metal conducts heat differently than the air fryer basket, so you may need to tweak cooking times. Cast iron, for example, takes longer to heat but retains heat well, which can affect cooking duration.
• Monitor Temperature: Most air fryers don’t exceed 450°F, but never heat beyond 500°F to avoid damaging nonstick coatings or releasing fumes, as noted by Homes & Gardens.
• Use Accessories Wisely: Metal racks or skewers can elevate food for better air circulation, creating crispier results. Just ensure they’re oven-safe and fit properly.

When to Skip Metal Altogether

In some cases, you might not need metal at all. Many air fryers come with a perforated basket designed for optimal airflow, and adding cookware can sometimes hinder performance. For foods like fries, wings, or veggies, the basket alone is often sufficient. If you’re worried about mess, silicone liners or parchment paper (specifically designed for air fryers) can be great alternatives to foil or metal pans, as they’re non-stick and heat-resistant without blocking airflow.

Final Thoughts: Metal Can Be Your Air Fryer’s Friend

Using metal in an air fryer is not only safe but can also expand your cooking options, from baking cakes in stainless steel tins to searing steaks in cast iron. The key is to choose oven-safe metals, ensure proper fit, and maintain good airflow. By avoiding nonstick-coated or painted metals and using foil wisely, you can make the most of your air fryer while keeping it safe and functional. Always check your air fryer’s manual for specific guidance, and don’t be afraid to experiment with metal cookware to elevate your air-frying game!
