Step‑by‑Step Instructions for Turkey Tetrazzini
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that your Turkey Tetrazzini will bake evenly and become golden while bubbling with rich flavors. A properly heated oven is essential for achieving that perfect, crispy top you’ll want to see at the end of baking.
Step 2: Cook the Pasta
In a large pot, bring salted water to a rolling boil. Carefully add the spaghetti or linguine, cooking until it’s just al dente according to package instructions—approximately 8–10 minutes. Stir occasionally to prevent sticking. Once cooked, drain the pasta and set it aside, letting it cool slightly as you prepare the other components of your Turkey Tetrazzini.
Step 3: Sauté the Aromatics
In a deep pot over medium-high heat, melt 4 tablespoons of unsalted butter until bubbly. Add chopped onion, sautéing for about 5 minutes until it turns translucent and fragrant. This step lays a flavorful foundation for your casserole, enhancing the rich essence you’ll discover in every bite of the Turkey Tetrazzini.
Step 4: Add the Vegetables
Add the baby Bella mushrooms to the onion, cooking for another 4–5 minutes until they soften and begin to release their juices. Then, stir in minced garlic and cook for an additional minute. The mixture will smell delicious, creating a warm, savory base for the creamy sauce you’re about to whip up for your Turkey Tetrazzini.
Step 5: Make the Creamy Sauce
Sprinkle the remaining butter and all-purpose flour into the pot, stirring continuously until well combined. Gradually pour in the chicken broth and heavy whipping cream, stirring to combine. Bring the mixture to a gentle simmer over medium heat, allowing it to thicken for about 5 minutes. You’ll know it’s ready when the sauce is creamy and coats the back of a spoon beautifully.
Step 6: Combine Ingredients
Season the creamy sauce with salt and ground black pepper to taste. Gently fold in one cup of shredded mozzarella cheese until melted and fully incorporated. Add the cooked spaghetti and shredded turkey, mixing everything until well combined. This deliciously creamy filling forms the heart of your comforting Turkey Tetrazzini.
Step 7: Transfer to Baking Dish
Pour the hearty mixture into a greased 9×13 inch baking dish, spreading it evenly. This allows for consistent baking and ensures every bite is filled with flavors. The warm, comforting casserole is now ready for its final touch before heading into the oven.
Step 8: Bake to Perfection
Sprinkle the remaining mozzarella cheese evenly over the top of the Turkey Tetrazzini. Bake uncovered in your preheated oven for 25-30 minutes, or until the top is golden brown and the edges are bubbling. This is the moment you’ll be rewarded with a wonderfully cheesy and savory dish, ready to serve and enjoy.
