This Turkey Tetrazzini recipe is the perfect way to enjoy leftover turkey. Tender turkey chunks, mushrooms and pasta are smothered in a rich and creamy sauce and topped with cheese.
Cook spaghetti according to package directions. Drain and place in a greased 11x7 baking dish. Top with turkey; set aside.
In a large skillet, saute the mushrooms and onion in butter until tender. Whisk in the soup, milk, poultry seasoning, and mustard until blended. Add cheddar cheese; cook and stir over medium heat until melted. Pour over turkey.
Sprinkle with mozzarella and Parmesan cheeses (dish will be full). Bake, uncovered, at 350° for 25-30 minutes or until completely heated. Sprinkle with parsley.
