If you're replacing pots and pans, opt for metal-handled models. That way you can use them on the stove and in the oven (meaning you can get rid of a casserole or two). Almost anything you can bake in a casserole dish — from macaroni and cheese to fillet of sole — you can bake in a saucepan or a saute pan. Any metal-handled pot is safe up to 400 degrees.
