Notes
Spaghetti: You can use regular or thin spaghetti noodles, and whole wheat spaghetti works, too. (Just follow the package instructions for cook time.) You could also substitute another long, thin pasta if you prefer. And some versions of this recipe use egg noodles.Mushrooms: I use regular white button mushrooms but you could also use baby Bella mushrooms.Half and half: Regular or fat-free half and half is fine to use here. You could also substitute whole milk. Sherry: Dry sherry or dry vermouth will work for this recipe.Turkey: The turkey needs to be cooked and chopped for this recipe. The idea is to use leftover roast turkey. You could also substitute cooked chicken, such as from a rotisserie chicken.How to freeze turkey tetrazzini: Assemble the casserole as directed, omitting the breadcrumb topping. Cover tightly with plastic wrap and then with aluminum foil. Label and freeze for up to 4 months. Defrost completely in the refrigerator overnight. Bring to room temperature as you preheat the oven. Add the breadcrumb topping and bake as directed, adding 5-10 minutes as needed to get the casserole hot and bubbling.Leftovers: Leftover turkey tetrazzini, once cooled, can be stored in a covered container in the refrigerator for up to 3-4 days. To freeze portions of the baked casserole, let cool then transfer to a freezer-safe container or tiptop bag and freeze for up to 3-4 months. Let thaw in the refrigerator and then reheat in the microwave.
