How to Make Creamy Turkey Tetrazzini
-
Preheat the oven to 350°F (175°C) and prepare your 9×13 casserole dish by greasing it lightly. This ensures a golden, bubbly finish to your dish!
-
Cook the spaghetti in salted boiling water until al dente, usually about 8-10 minutes. Drain it well and set it aside, as it will absorb some of the delicious sauce later.
-
Melt the butter in a large skillet over medium heat. Once melted, add the diced onion and cook until softened, about 3-4 minutes. The aroma will begin to tantalize your senses!
-
Sauté the garlic and sliced mushrooms, stirring until the mushrooms are golden brown, around 5-7 minutes. This deepens the flavor profile and adds a delightful texture.
-
Sprinkle the flour over the vegetable mixture, stirring to form a roux. Cook it for about 1 minute to eliminate the raw flour taste.
-
Whisk in the broth slowly, keeping it smooth until the mixture thickens, roughly 3-4 minutes. You want a velvety texture that clings to your pasta!
-
Stir in the heavy cream, parmesan, salt, black pepper, and Italian seasoning, allowing the sauce to simmer for an additional 2-3 minutes. This makes your sauce luxuriously creamy!
-
Add the cooked spaghetti and shredded turkey to the sauce, mixing thoroughly to ensure everything is coated in that comforting creamy goodness.
-
Transfer the mixture into the prepared casserole dish, spreading it evenly. Then, top it generously with shredded mozzarella cheese for that perfect melty finish.
-
Bake in the preheated oven for 25–30 minutes, or until the top is bubbly and golden brown. Patience is key as you wait for that crispy top!
-
Cool for 5–10 minutes before serving. This helps the layers settle, and garnishing with chopped parsley adds a lovely touch of color and freshness.
Optional: Sprinkle additional parmesan on top before serving for an extra cheesy delight!

Make Ahead Options
These Creamy Turkey Tetrazzini make-ahead options are perfect for busy home cooks looking to save time while enjoying a comforting meal! You can prepare the casserole up to 24 hours in advance by following the first eight steps of the recipe and then refrigerating the mixture (just be sure to cover it tightly to maintain freshness). When you're ready to bake, simply add the mozzarella on top and pop it in the oven straight from the fridge (add an extra 5-10 minutes to the baking time).

Chef's Helpful Tips
- To ensure your Creamy Turkey Tetrazzini has the best flavor, use freshly grated parmesan instead of pre-grated for optimal melt and taste.
- Be cautious not to overcook the spaghetti; it should be al dente since it will continue to cook in the oven and soak up the sauce.
- For a creamier sauce, consider adding a bit more heavy cream or half-and-half as it simmers, but maintain a balance to avoid overpowering the dish.
- Remember to let the casserole cool slightly before serving to allow the flavors to meld and the dish to set properly.
