Most heat resistance, non-metallic cookware is safe for use in your microwave oven. Some dish (melamine, ceramic dinnerware, etc) absorb microwave energy and become too hot to handle. Cooking in metal containers not designed for microwave use could damage the oven, so are containers with hidden metal (twist-ties, foil lining, staples, metallic glaze or trim).

Food stiring during cooking.
If the food is not completely defrosted before cooking, it will cause uneven cooking. For best cooking results, defrost the food before choosing a cooking cycle.

The shape of the package affects how quickly food will defrost. Shallow packages will defrost more quickly than a deep block.
