Chicken Tetrazzini combines cooked vermicelli, chicken, and mushrooms with a rich sherry–Parmesan cheese sauce. The mixture is sprinkled with breadcrumbs and Parmesan cheese and baked until bubbly and golden. This is a great way to use leftover cooked chicken.
Parmesan is full of flavor, so a little goes a long way. We recommend buying the real thing, which has Parmigiano-Reggiano printed on the rind. It has a sharper taste and a firmer texture than domestic Parmesan.
