Are hard anodized aluminum pans oven-safe? I have a full metal "hard anodized aluminum" pan which I'd like to use in the oven. I heard non-stick pans in the oven are unsafe.

This pan comes with: no "oven-safe" label, a metal handle on the pan, a glass lid with a plastic handle on it. Because of the glass lid with plastic handle, I assume it's not designed to go into an oven.

Can I still safely use this pan in the oven?
An anodized finish is chemically stable. It does not decompose. It is nontoxic. High heat levels will not damage the anodized finish. Anodized surfaces are heat-resistant to the melting point of aluminium (1,221°F).

The issue you will have is if the rest of the pan is safe, such as the handle.
