Best cookware for cooking in a microwave?

Examine the packaging to be sure, but all stainless and cast-iron cookware are oven and broiler safe.

Non-stick cookware is safe up to about 450 degrees F. But the non-stick coating can begin to melt at that point. So don't put it under the broiler.

This rule holds true for just about any brand with one exception. Calphalon Infused Anodized cookware does not have a traditional nonstick coating and is oven safe up to the melting point of aluminum according to Calphalon's website.
