Glass or microwave-safe plastic containers are the best for reheating food in the microwave. Ensure the container is labeled 'microwave-safe' to avoid harmful chemicals leaching into your food.
When choosing prep containers for microwave reheating, several factors come into play, primarily safety and effectiveness.
Glass Containers: Glass containers are generally considered the safest option. They are non-porous, meaning they won't absorb odors or flavors from food, and they don't leach chemicals when heated. Look for tempered glass containers specifically designed for microwave use. These are more resistant to thermal shock (sudden temperature changes) and less likely to shatter.
Microwave-Safe Plastic Containers: Plastic containers labeled as 'microwave-safe' are also a viable option. These plastics are designed to withstand microwave temperatures without melting or releasing harmful chemicals like BPA. Always check for the microwave-safe symbol (usually a picture of a microwave with wavy lines) on the container. Avoid using plastic containers that are not specifically labeled as microwave-safe, as they may melt or leach chemicals into your food.
Containers to Avoid: Never use metal containers or aluminum foil in the microwave, as they can cause sparks and potentially damage the appliance. Also, avoid using containers with metallic trim or decorations. Single-use plastic containers, like those from takeout, are generally not designed for reheating and should be avoided.
When reheating food in the microwave, leave a small vent in the container by slightly lifting the lid or covering it loosely with microwave-safe plastic wrap. This allows steam to escape, preventing pressure buildup and potential explosions, and helps to heat the food more evenly.
