This guide dives deep into the science, safety, and practical considerations of using metal in air fryers. We’ll explore what types of metal are safe, which ones to avoid, best practices for safe use, and how to maximize cooking efficiency without compromising your appliance or health. By the end, you’ll be equipped with the knowledge to make informed decisions and cook with confidence.

Understanding How Air Fryers Work and Why Materials Matter

The Science Behind Air Frying Technology

Air fryers function by circulating hot air at high speeds (typically between 300°F and 400°F) around food using a powerful convection fan. This rapid airflow creates a Maillard reaction—the browning process responsible for crispy textures—without submerging food in oil. The cooking chamber is usually compact, with a heating element at the top and a fan that forces air downward, then around the food. The efficiency of this system depends heavily on airflow patterns and heat distribution.

Because of this design, the materials inside the air fryer must not disrupt airflow, reflect heat unpredictably, or conduct electricity in unintended ways. Metal, while excellent at conducting heat, can also reflect radiant heat or create hotspots if improperly placed. Additionally, the proximity of metal to the heating element (often just a few inches away) means that even small metal objects can overheat or spark under certain conditions.

Why Material Compatibility Is Critical

Air fryers are typically lined with non-stick coatings, such as PTFE (Teflon) or ceramic, which are sensitive to scratches and high temperatures. Introducing incompatible materials—especially sharp or reactive metals—can damage these surfaces, reducing the lifespan of your appliance and potentially releasing harmful compounds. Furthermore, some metals can interfere with the electrical components of the air fryer. For instance, aluminum foil or thin metal containers may come too close to the heating element, causing overheating, smoke, or even fire.

Another concern is arcing—a phenomenon where metal objects create an electrical spark between the heating element and grounded parts of the air fryer. This is rare but possible with conductive metals like copper or aluminum when placed too close to the heating coil. The risk increases with crumpled foil or thin metal sheets that can vibrate and make contact during operation.

Common Misconceptions About Metal Use

Many users assume that because metal is used in conventional ovens and toaster ovens, it’s automatically safe in air fryers. However, air fryers have smaller cavities and faster air circulation, making them more sensitive to material placement. For example, a metal baking dish that works fine in a full-sized oven might block airflow in an air fryer, leading to uneven cooking or overheating. Similarly, metal skewers or racks may seem harmless, but their shape and position can affect performance.

• Misconception: “If it fits, it’s safe.” – Size and placement matter more than just physical fit.
• Misconception: “All metal is the same.” – Different metals (stainless steel, aluminum, copper) behave differently under high heat and airflow.
• Misconception: “I’ve used foil before without issues.” – Past success doesn’t guarantee future safety; risks accumulate over time.

Types of Metal: What’s Safe and What’s Not

Stainless Steel: The Best Option (With Conditions)

Stainless steel is generally the safest metal to use in air fryers—when used correctly. It’s durable, non-reactive, and can withstand high temperatures without warping or leaching chemicals. Many air fryer manufacturers include stainless steel racks, trays, or baskets in their accessory kits, indicating that it’s approved for use.

However, there are important caveats:

• Use only solid stainless steel containers (e.g., baking pans, loaf tins) that are designed for oven or air fryer use.
• Avoid placing stainless steel directly on the heating element or too close to it. Leave at least 1–2 inches of clearance.
• Do not use scratched or damaged stainless steel, as it may harbor bacteria or react with acidic foods.

Example: You can safely cook a small meatloaf in a stainless steel loaf pan inside your air fryer, as long as it fits without touching the heating element and allows airflow around the sides. The pan will conduct heat evenly, helping the meat cook uniformly.

Aluminum Foil: Risks and Limited Use

Aluminum foil is one of the most debated materials in air fryer cooking. While it’s technically a metal, its thin, malleable nature makes it risky. Here’s what you need to know:

• Do not use loose or crumpled foil that can flutter near the heating element. This can cause overheating, arcing, or fire.
• You can use foil in moderation to cover the basket’s bottom or wrap individual items (e.g., fish, vegetables), but only if:
  • It’s tightly secured and doesn’t touch the heating element.
  • It doesn’t block more than 20% of the basket’s surface area.
  • You avoid acidic foods (like tomatoes or citrus) in direct contact with foil, which can cause aluminum leaching.

Tip: If you want to line the basket, use parchment paper instead. It’s safer, more breathable, and prevents sticking without the risks of foil.

Copper, Non-Stick Metal, and Other Reactive Metals

Copper is highly conductive and reactive, making it unsuitable for air fryers. It can cause rapid overheating and may leach into food, especially when combined with acidic ingredients. Never use copper pots, pans, or utensils in your air fryer.

Non-stick metal pans (e.g., Teflon-coated baking dishes) are also risky. The coating can degrade at high temperatures (above 500°F), releasing toxic fumes. Even if your air fryer doesn’t reach that temperature, localized hotspots near the heating element can exceed safe limits. Always check the manufacturer’s temperature rating before using any coated metal.

Other metals to avoid:

• Cast iron – Too heavy, may damage non-stick surfaces, and can create uneven airflow.
• Galvanized steel – Contains zinc, which can vaporize and release toxic fumes at high heat.
• Aluminum containers with non-stick coatings – Combines two risk factors: reactive metal and potential fume release.

Metal Utensils: A Hidden Hazard

Even if your cookware is safe, using metal utensils (spatulas, tongs, forks) inside the air fryer can scratch the non-stick coating. Over time, scratches expose the underlying metal, which can rust or react with food. Always use silicone, nylon, or wooden utensils when removing food from the basket or stirring during cooking.

Best practice: Invest in a set of air fryer-safe silicone tools. They’re heat-resistant, non-scratching, and designed for tight spaces.

Best Practices for Using Metal Safely in Your Air Fryer

1. Follow Manufacturer Guidelines

Every air fryer model has unique design specifications. Always consult your user manual for a list of approved materials. For example:

• Some brands (like Philips) explicitly state that stainless steel and oven-safe glass are safe.
• Others may warn against any metal, even if it’s oven-safe.
• Look for phrases like “air fryer-safe” or “convection oven compatible” on accessory packaging.

If your manual doesn’t mention metal, contact customer support. Don’t assume compatibility based on other appliances.

2. Ensure Proper Airflow and Clearance

Airflow is the lifeblood of air frying. When using metal, maintain these guidelines:

• Leave at least 1 inch of space between any metal object and the heating element.
• Use shallow containers to avoid blocking vertical airflow.
• Arrange food in a single layer with space between pieces.
• Rotate or stir food halfway through cooking to ensure even exposure to hot air.

Example: When cooking chicken wings in a stainless steel mesh basket, don’t overcrowd them. Leave gaps so hot air can circulate and crisp all sides.

3. Use Oven-Safe Metal Accessories

Invest in accessories specifically designed for air fryers. These are tested for heat resistance, airflow, and safety. Popular options include:

• Stainless steel racks – Elevate food for even cooking.
• Metal skewers – Use for kebabs, but ensure they don’t touch the heating element.
• Oven-safe baking pans – Ideal for cakes, casseroles, or lasagna.

Brands like Ninja, Cosori, and Instant Pot offer compatible metal trays and racks. Check dimensions before purchasing—some are model-specific.

4. Avoid High-Risk Scenarios

Even with safe materials, certain situations increase risk:

• Preheating with metal inside – Always preheat the empty air fryer, then add food and containers.
• Using metal with wet or greasy foods – Splatter can coat the heating element, increasing fire risk.
• Overfilling the basket – Crowded food can touch the heating element, especially with metal trays.
• Using damaged metal – Dents, warps, or sharp edges can disrupt airflow or cause sparks.

5. Monitor Cooking Closely

When using metal for the first time, stay nearby. Watch for:

• Unusual smells (burning plastic or metal).
• Smoke or sparks.
• Uneven cooking (indicating blocked airflow).

If you notice any of these, turn off the air fryer immediately, unplug it, and inspect the contents.

Alternative Materials: Safer and Often Better Choices

Oven-Safe Glass and Ceramic

Glass (e.g., Pyrex) and ceramic are excellent alternatives to metal. They’re non-reactive, easy to clean, and distribute heat evenly. Most oven-safe glass containers can be used in air fryers, provided they fit and don’t touch the heating element.

Tip: Use a glass loaf pan for air fryer banana bread. It retains heat well and prevents sticking without oil.

However, avoid sudden temperature changes (e.g., placing a cold glass dish into a hot air fryer), as this can cause cracking.

Silicone: Flexible and Heat-Resistant

Silicone molds, mats, and pans are increasingly popular for air frying. They’re non-stick, dishwasher-safe, and won’t scratch your basket. Look for FDA-approved, food-grade silicone rated for temperatures up to 450°F.

Example: Make air fryer egg bites in silicone muffin cups. They pop out easily and clean up in seconds.

Parchment Paper and Perforated Liners

These are ideal for preventing sticking without metal. Choose:

• Unbleached parchment paper – Place at the bottom of the basket for easy cleanup.
• Perforated air fryer liners – Allow airflow while protecting the basket.

Avoid wax paper or regular paper towels, which can catch fire at high temperatures.

Non-Stick Metal (Only If Certified)

If you must use non-stick metal, ensure it’s:

• Marked as “air fryer-safe” or “convection oven-safe.”
• Rated for temperatures above 400°F.
• Free of PFOA and PTFE (look for ceramic or diamond-infused coatings).

Even then, use it sparingly and inspect regularly for coating wear.
