You can put a copper pan in the oven if you’re making a dessert like a tarte Tatin, but remember that copper can’t take the high heat of cast iron or stainless, so most manufacturers don’t recommend temperatures above 450 °F.

We also cook foods that require controlled heat, including risotto, a gooey banana tarte Tatin, and melted white chocolate. All the copper pans perform well, Fisher says.
Here are two recommended copper pans from CR’s tests.
