Ingredients
- 3 cups cooked turkey, shredded or chopped
- 8 ounces spaghetti or linguine
- 2 tablespoons butter
- 2 tablespoons all-purpose flour
- 2 cups chicken or turkey broth
- 1 cup milk (whole or 2%)
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon nutmeg (optional, for warmth)
- 1/2 cup grated Parmesan cheese
- 1 cup shredded mozzarella cheese
- 1/2 cup sliced mushrooms (optional)
- 1/4 cup chopped parsley, for garnish
- 1/2 cup breadcrumbs (optional, for topping)
Instructions
- Cook the pasta: Bring a large pot of salted water to a boil. Cook spaghetti or linguine according to package directions until al dente. Drain and set aside.
- Prepare the sauce: In a large saucepan, melt butter over medium heat. Stir in flour and cook for 1–2 minutes to form a roux. Slowly whisk in broth and milk, cooking until the sauce thickens, about 5–7 minutes. Season with salt, pepper, and nutmeg.
- Add the cheese: Stir in 1/2 cup Parmesan and half of the mozzarella until melted and smooth.
- Combine ingredients: In a large mixing bowl, combine the cooked pasta, turkey, mushrooms (if using), and creamy sauce. Toss until everything is evenly coated.
- Assemble the casserole: Preheat your oven to 350°F (175°C). Pour the mixture into a greased 9×13-inch baking dish. Sprinkle the remaining mozzarella and breadcrumbs on top for a golden finish.
- Bake: Bake uncovered for 25–30 minutes, or until the top is bubbly and golden brown.
- Garnish and serve: Sprinkle with fresh parsley and a little extra Parmesan, if desired. Serve hot and enjoy!

Tips for the Best Turkey Tetrazzini
- Leftover turkey: This recipe shines when using leftover roasted turkey, but cooked chicken works just as well.
- Make it ahead: Assemble the casserole a day in advance and bake it just before serving.
- Add veggies: Peas, spinach, or broccoli can add color, flavor, and nutrition.
- Cheese lovers: Feel free to experiment with Gruyère or cheddar for a twist.
