Step‑by‑Step Instructions for Chicken Tetrazzini Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). While the oven warms up, generously butter a 9×13 casserole dish, ensuring a non-stick surface for your Chicken Tetrazzini. This simple step lays the groundwork for a beautifully baked, bubbly casserole that you and your loved ones will savor.
Step 2: Cook the Pasta
In a large pot, bring well-salted water to a boil and add your choice of linguine or spaghetti. Cook until the pasta is barely al dente, usually about 2 minutes less than the package instructions. Once done, drain the pasta, reserving half a cup of the starchy water for later, and set it aside while you focus on the flavorful filling.
Step 3: Sauté the Vegetables
In a large skillet, heat a drizzle of olive oil over medium-high heat. Add the sliced button mushrooms and cook until softened and slightly golden, about 5 minutes. Next, incorporate diced onions and continue cooking until they turn translucent and golden, approximately 3-4 minutes. Finally, stir in minced garlic and cook until fragrant, about 30 seconds, before transferring everything to a bowl with shredded chicken.
Step 4: Make the Sauce
In the same skillet, melt 4 tablespoons of unsalted butter over medium heat. Once it’s bubbling, whisk in an equal amount of all-purpose flour until it becomes lightly golden, about 2 minutes. Gradually pour in low-sodium chicken broth and lemon juice while whisking continuously until smooth and slightly thickened. Let it simmer for about 3-4 minutes, enhancing the flavors before stirring in the half & half.
Step 5: Combine Ingredients
Return the cooked pasta, chicken mixture, and freshly chopped parsley to the skille. Pour the creamy sauce over the top and gently stir everything together until well combined, ensuring every piece of pasta is coated in luscious goodness. With your Chicken Tetrazzini ready, spread the mixture evenly in the prepared casserole dish, creating an inviting layer of flavors.
Step 6: Bake to Perfection
Cover your assembled Chicken Tetrazzini with aluminum foil and place it in the preheated oven. Bake for 20 minutes to allow all the flavors to meld together. After that, carefully remove the foil and sprinkle a generous layer of shredded mozzarella cheese on top. Ounce it bakes for another 15 minutes, broil for the last minute to achieve that beautiful golden crust.

Make Ahead Options
These Chicken Tetrazzini are perfect for busy home cooks looking to save time! You can prepare the entire casserole up to 24 hours in advance by assembling it fully and covering it tightly with foil before refrigerating. Just make sure to chill the dish promptly to maintain freshness. If you want to prep even further ahead, you can freeze the unbaked Chicken Tetrazzini for up to 3 months. When you’re ready to bake, thaw it overnight in the refrigerator and follow the original baking instructions. This way, you’ll enjoy a comforting, creamy meal that’s just as delicious as when it’s freshly made, with minimal effort when it’s time to serve!
