The Great Air Fryer Metal Debate: What You Need to Know

Air fryers have revolutionized the way we cook, offering a healthier alternative to traditional deep frying with the same crispy results. These countertop appliances use rapid air circulation to cook food evenly and quickly, making them a staple in many modern kitchens. However, as their popularity grows, so do questions about their safe and effective use—one of the most common being: can you put metal in an air fryer?

Whether you’re a seasoned air fryer enthusiast or a curious first-time user, the answer isn’t always straightforward. The short answer is: sometimes. But the real answer involves understanding the mechanics of your air fryer, the type of metal you’re using, and the potential risks to both your appliance and your safety. In this comprehensive guide, we’ll explore everything you need to know about using metal in air fryers, from safety precautions to best practices, so you can cook with confidence and avoid costly mistakes.

How Air Fryers Work and Why Metal Matters

The Science Behind Air Frying

To understand why metal can be a double-edged sword in air fryers, it’s essential to first grasp how these appliances function. Air fryers operate by circulating hot air at high speeds around food, typically between 175°F and 400°F (80°C–205°C). A heating element at the top of the unit warms the air, while a powerful fan pushes it down and around the food basket, creating a convection effect that crisps the exterior while cooking the interior.

This process relies on precise temperature control and even air distribution. Any obstruction—especially conductive materials like metal—can disrupt airflow, cause uneven cooking, or even damage the appliance’s internal components.

Why Metal Interacts Differently Than Other Materials

Metal is an excellent conductor of heat, which makes it ideal for cookware in ovens and stovetops. However, in an air fryer, this property can be problematic. Unlike ovens, which are designed to handle metal pans, air fryers have a compact design with sensitive heating elements and fans located close to the cooking chamber. Placing metal objects too close to these components can:

• Cause arcing (sparks) if the metal touches the heating element
• Reflect heat unpredictably, leading to hot spots or undercooked areas
• Damage non-stick coatings on the basket or tray
• Interfere with the fan’s ability to circulate air evenly

Moreover, some metals—especially thin or lightweight ones—can warp or melt under high heat, potentially releasing harmful fumes or contaminating food. For example, aluminum foil, if used improperly, can overheat and stick to food or the basket, creating a fire hazard.

Real-World Example: The Case of the Melting Foil

Many users report incidents where they placed a crumpled piece of aluminum foil in the basket to catch drippings, only to find it had partially melted and fused to the basket’s non-stick coating. This not only ruins the basket but also makes cleaning difficult and may require costly replacement. The issue? The foil was too thin and made direct contact with the heating element or was placed too close to it, causing it to overheat beyond its melting point (around 1220°F/660°C, but thin foil can degrade at much lower temps due to poor heat distribution).

Types of Metal You Can (and Can’t) Use in Air Fryers

Approved Metal Cookware and Accessories

The good news is that not all metal is off-limits. In fact, many manufacturers design air fryer-safe metal accessories that enhance functionality. Here are the types of metal you can safely use:

• Stainless Steel Pans and Racks: Heavy-duty stainless steel (especially 304 or 316 grade) is non-reactive, durable, and safe for air fryers when used correctly. Look for pans labeled “air fryer safe” or “oven safe up to 500°F.” These are ideal for cooking foods that require a flat surface, like frittatas or reheating pizza.
• Metal Skewers and Sticks: Stainless steel skewers are excellent for kebabs, chicken wings, or vegetable skewers. Ensure they are long enough to fit across the basket without touching the heating element (usually at least 8–10 inches).
• Metal Baking Cups: Silicone-lined metal muffin cups are safe and reusable. They’re perfect for cupcakes, egg muffins, or mini quiches. Avoid flimsy foil liners, which can collapse or overheat.
• Air Fryer-Specific Metal Trays: Some brands sell metal drip trays or crisper plates designed to fit inside the basket. These often have raised edges and ventilation holes to promote airflow while catching grease.

Pro Tip: Always check your air fryer’s user manual for approved accessories. For example, Philips and Ninja both sell stainless steel racks and pans explicitly designed for their models.

Metals to Avoid (and Why)

While some metals are safe, others pose significant risks. Here’s what to avoid:

• Aluminum Foil (Crumpled or Direct Contact): While foil is technically “metal,” it’s often too thin and reflective. Crumpled foil can block airflow and touch the heating element, causing sparks. If you must use foil, never let it touch the walls or heating element, and use it only as a flat liner (with holes for airflow) or to cover food loosely.
• Non-Stick Metal Pans with Damaged Coatings: Chipped or scratched non-stick pans can leach chemicals when heated. Even if the base is metal, the coating breakdown makes them unsafe.
• Lightweight or Thin Metal Containers: Disposable aluminum pans, takeout containers, or flimsy metal tins can warp or melt at high temperatures.
• Cast Iron (Without Caution): While cast iron is metal, its high thermal mass can absorb too much heat, causing the air fryer to overwork or overheat. If used, preheat it separately and place it on a rack (not the basket base) to avoid direct contact with the heating element.
• Metal Utensils for Stirring: Using metal tongs or spatulas inside the basket can scratch non-stick coatings. Opt for silicone or wooden tools instead.

Example: A user placed a disposable aluminum pie tin in their air fryer to bake a quiche. The tin warped within 5 minutes, spilling batter into the heating element and causing smoke. The lesson? Only use heavy-duty, oven-safe metal pans.

Special Case: Metal vs. Ceramic-Coated Metal

Many air fryer baskets are made of metal with a ceramic or PTFE (Teflon) non-stick coating. These coatings are safe when intact but degrade if scratched by metal utensils. Never use metal accessories that could scratch the basket. If your basket is damaged, replace it—don’t risk chemical exposure.

Safety Risks of Using Metal in Air Fryers

Electrical Hazards and Arcing

The most serious risk of improper metal use is electrical arcing. Air fryers have a heating element (often a coil or rod) located just above the cooking chamber. If a piece of metal—like a skewer, pan, or crumpled foil—touches this element while the appliance is on, it can create sparks or short circuits. This can:

• Damage the heating element or control board
• Trip your home’s circuit breaker
• Cause a fire in extreme cases

Data Point: A 2022 study by the National Fire Protection Association (NFPA) found that small appliance fires, including those from air fryers, accounted for 14% of kitchen fires in the U.S., with improper use of metal cookware cited as a contributing factor in 3% of cases.

Heat Distribution Issues

Metal’s high thermal conductivity can lead to uneven cooking. For example, a thick stainless steel pan may:

• Cook the bottom of food faster than the top
• Block airflow, resulting in soggy or undercooked areas
• Require adjusting cooking times (usually adding 2–5 minutes)

Solution: Use a metal rack or pan with ventilation holes to allow air to circulate. For instance, a perforated stainless steel tray is better for roasting vegetables than a solid pan.

Coating Damage and Chemical Leaching

Scratching the air fryer basket with metal utensils or pans can damage non-stick coatings, leading to:

• Food sticking and difficult cleaning
• Potential release of PTFE or PFOA (if the coating is old or low-quality)
• Reduced appliance lifespan

Tip: If you notice peeling or flaking in your basket, replace it immediately. Most manufacturers offer replacement baskets for under $20.

Fire and Melting Risks

Thin metals (like foil or takeout containers) can overheat and melt, especially if they touch the heating element. Signs of trouble include:

• Smoke or a burning smell
• Discoloration on the basket or pan
• Warping or bubbling of the metal

Example: A user placed a foil-wrapped potato directly on the air fryer basket. The foil touched the heating element, ignited, and caused a small fire. The air fryer was ruined, and the kitchen filled with smoke. Always keep metal at least 1 inch away from the heating element.

Best Practices for Using Metal in Air Fryers

Step-by-Step Guide to Safe Metal Use

1. Check Compatibility: Only use metal accessories labeled “air fryer safe” or “oven safe up to 500°F.” Avoid generic or thin-metal cookware.
2. Maintain Clearance: Ensure metal pans, racks, or skewers are at least 1 inch away from the heating element and basket walls.
3. Preheat When Needed: For heavy metal pans (like cast iron), preheat them separately to avoid overloading the air fryer’s heating system.
4. Use Ventilation: Choose metal trays or pans with holes or raised edges to promote airflow.
5. Monitor Cooking: Check food every 5–7 minutes when using metal to prevent overheating or uneven cooking.
6. Clean Gently: Hand-wash metal accessories with soft sponges to avoid scratching. Never use steel wool.

Creative Uses of Metal (With Caution)

Metal can actually enhance your air frying experience when used wisely. Try these ideas:

• Metal Skewers for Kebabs: Thread chicken, vegetables, or shrimp onto stainless steel skewers. Place them horizontally across the basket, ensuring they don’t touch the heating element.
• Stainless Steel Pan for Casseroles: Bake a small lasagna or mac and cheese in a 6-inch stainless steel pan. Place it on the basket’s base (not directly on the heating element) and add 2–3 minutes to the cook time.
• Metal Rack for Crispy Foods: Use a rack to elevate chicken wings or bacon, allowing grease to drip away and air to circulate for extra crispiness.
• Reheating Pizza: Place a slice on a small metal plate to prevent the crust from getting soggy. Avoid letting the plate touch the heating element.

Pro Tip: For delicate foods (like fish), use a metal tray lined with parchment paper to prevent sticking without risking coating damage.

Alternatives to Metal (When in Doubt)

If you’re unsure about using metal, opt for:

• Silicone Molds and Pans: Heat-resistant (up to 425°F), flexible, and non-stick. Great for baking or holding small items.
• Parchment Paper: Use perforated parchment in the basket to catch drippings without blocking airflow.
• Oven-Safe Glass or Ceramic: Safe for air fryers if labeled “microwave/oven safe.” Avoid sudden temperature changes to prevent cracking.
