Key Ingredients:
This is one of our amazing leftover recipes, so you will need baked or cooked turkey from Thanksgiving dinner (or any dinner) to create the protein for this dish.
The creamy base of this pasta recipe is made up from a combination of chicken stock, flour, butter, and half-and-half (or heavy cream).
Then add in fresh mushrooms and any veggies like peas or chopped broccoli for added flavor.
Tagliatelle is the pasta used in this dish, but you can use whatever pasta you prefer.



How To Make Turkey Tetrazzini:
- Cook your desired type of pasta in a large pot of salted water according to the package directions. Make sure your pasta is al dente and not overcooked, or the pasta will get mushy once it bakes.
- Preheat oven to 350°F and prepare a 9×13-inch baking dish.
- Melt the butter in a large skillet over medium-high heat. Then add shallots and celery, and cook, stirring for 5 minutes.
- Add garlic and cook until fragrant, adding the mushrooms as well, and cooking until just tender.
- Create the roux for this heavy cream base by stirring in flour and cooking it for 1 minute.
- Pour in the chicken stock and half cream, cooking it for 1 minute.
- Stir in cream cheese, sour cream, and Italian seasoning to create the creamy base. Then remove it from the heat.
- Make sure the sour cream is well mixed; otherwise, lumps of sour cream may form after baking.
- Mix the cooked pasta, turkey, and ½ cup of mozzarella with the prepared sauce in a large skillet.
- Transfer the mixture into the baking dish. Top with the remaining mozzarella and parmesan cheese to create an easy, crunchy topping.
- Bake for 25 minutes or until the cheese is melted and bubbly.
- Cool for 10 minutes before serving.
- Serve garnished with basil or chopped parsley.

- Linguine or egg noodles are great options for this casserole dish.
