No, you absolutely cannot use a standard metal baking tray in the microwave.
Putting metal in a microwave is a major safety hazard and can damage the appliance. Here's why:
-
Sparks and Arcing: Microwaves use electromagnetic radiation to heat food. Metal reflects these waves, causing sparks and arcing (electrical discharge). This can lead to a fire.
-
Potential for Explosion: In extreme cases, the buildup of electromagnetic energy can cause components within the microwave to explode.
-
Damage to the Microwave: Even without an explosion, the reflected microwaves can damage the magnetron, the part of the microwave that generates the microwaves.
-
Uneven Cooking (or No Cooking): Metal will block the microwaves from reaching the food, resulting in uneven or no cooking.
Instead of metal baking trays, use microwave-safe cookware. This usually includes:
- Glass
- Ceramic
- Microwave-safe plastic
Always check that any dish you intend to use in the microwave is specifically labeled as microwave-safe.
