This 12” Covered Chef’s pan has a round base and deeply curved sides which work well for stir frys and one pot meals. The stainless steel lid helps to maintain heat, control evaporation, and reduce splatters. Viking’s Professional 5-ply cookware is constructed to maximize heat transfer for even heating across the base and up the sides of the pan: a non-reactive 18/10 stainless steel interior, 3-ply aluminum core, and stainless steel exterior. It is stovetop (including induction), oven, and grill friendly to 600°F. The ergonomic handle is designed for comfort, control, and balance, and stays cool on the stovetop.
