Instructions
Step 1 : Prepare Spaghetti
Pour it into a large pot of salted water and heat until it reaches a steady boil before adding the spaghetti. Cook until al dente, firm to the bite, then drain thoroughly and drizzle with olive oil to prevent the noodles from sticking together.
Tip : When making Freezer Turkey Tetrazzini, cook the pasta a touch under al dente so it holds its texture beautifully after freezing and reheating.
Step 2 : Sauté Vegetables
In a skillet over medium heat, put butter and add the onion, cooking until it becomes translucent.
Stir in the garlic and mushrooms, then sauté until the mushrooms release moisture and turn golden.
This flavorful base is perfect for building your Freezer Turkey Tetrazzini.

Step 3 : Make the Creamy Sauce
Sprinkle flour over vegetables and stir 1 minute. Gradually whisk in chicken broth and milk. Simmer until thickened. Add cream cheese and Parmesan, stirring until smooth.
Tip: Whisk constantly to keep sauce silky.
According to USDA food safety guidelines, leftovers should reach 165°F when reheated.
Step 4 : Combine and Assemble
Fold shredded turkey and cooked pasta into the sauce. Move the mixture into a prepared 9x13-inch baking dish. Top with mozzarella evenly.

For immediate baking: Cover and bake for 25 minutes, then uncover and bake 10 more minutes until the top turns golden and the sauce bubbles.
