How to Make Creamy Turkey Tetrazzini
-
Preheat the oven to 350°F (175°C) and grease a 9×13 casserole dish. This ensures your tetrazzini bakes evenly and doesn't stick, giving you a perfectly golden top.
-
Cook the spaghetti in a large pot of salted boiling water until al dente, about 8-10 minutes. Drain and set it aside while you prepare the creamy filling.
-
Melt the butter in a skillet over medium heat. Add the diced onion and cook until softened, about 3-5 minutes, filling your kitchen with a savory aroma.
-
Sauté the garlic and sliced mushrooms until the mushrooms are browned, approximately 5-7 minutes. This step enhances the flavor profile of your tetrazzini!
-
Sprinkle the flour evenly over the vegetables and stir to form a roux, cooking for another minute until lightly browned. This creates the base for your creamy sauce.
-
Whisk in the broth gradually, stirring until smooth and thickened. This will take around 3-5 minutes, resulting in a rich sauce that will bind everything together.
-
Stir in the heavy cream, grated parmesan, salt, pepper, and Italian seasoning, mixing well until combined and creamy. The mixture should be velvety and beautifully fragrant.
-
Add the cooked pasta and shredded turkey to the sauce, mixing thoroughly to coat every noodle in that luscious creamy goodness.
-
Transfer the mixture into the greased casserole dish and top generously with shredded mozzarella. This will melt beautifully as it bakes!
-
Bake for 25–30 minutes until the topping is bubbly and golden brown. You'll know it's ready when your kitchen smells like heaven!
