How to Make Creamy Chicken Tetrazzini Recipe
Step 1: Prep the Oven and Pasta
Begin by preheating your oven to 375°F and greasing a 9×13-inch baking dish to ensure your tetrazzini doesn’t stick. Then, cook your spaghetti or linguine in a large pot of salted boiling water just until al dente. This ensures the pasta has enough bite to hold up against the creamy sauce and baking process without becoming mushy.
Step 2: Sauté Aromatics and Mushrooms
In a large skillet over medium heat, melt the butter with olive oil. Add the finely chopped onion and sauté for 2 to 3 minutes until it becomes soft and translucent, creating a fragrant base. Next, stir in the minced garlic and sliced mushrooms, cooking for about 5 minutes until the mushrooms soften and release their savory juices, enriching your dish with deep, earthy flavors.
Step 3: Create the Creamy Sauce
Sprinkle the flour into the skillet and stir continuously for 1 to 2 minutes. This step cooks out the raw flour taste and forms a roux that will thicken your sauce. Slowly whisk in the chicken broth followed by the whole milk and heavy cream, making sure the mixture stays smooth. Allow the sauce to simmer gently for 4 to 5 minutes until it thickens to a luscious, velvety consistency that will coat every noodle perfectly.
Step 4: Add Cheese, Seasonings, and Chicken
Stir in the grated Parmesan cheese to introduce that unmistakable nutty tang, then season with salt, black pepper, and if you like, a pinch of ground nutmeg to add warmth. Toss in the shredded cooked chicken and the drained pasta, mixing everything thoroughly so each strand is wrapped in the creamy, flavorful sauce.
Step 5: Bake to Golden Perfection
Transfer this heavenly mixture into your prepared baking dish. Top it generously with shredded mozzarella cheese and breadcrumbs if you want a crunchy crust. Bake uncovered for 20 to 25 minutes until the edges bubble and the top turns a gorgeous golden brown. Let it rest for 5 minutes after baking—this step ensures the sauce sets slightly, making it easier to serve while still meltingly creamy.
How to Serve Creamy Chicken Tetrazzini Recipe

Garnishes
After that final resting moment, sprinkle chopped fresh parsley atop the casserole. The parsley adds a beautiful burst of green that brightens the dish visually and brings a fresh, herbal note to balance the richness.
Side Dishes
This creamy, hearty dish pairs wonderfully with crisp green salads or steamed vegetables like broccoli or green beans. The freshness and crunch of the sides provide a lovely contrast that keeps the meal balanced and satisfying without feeling too heavy.
Creative Ways to Present
For an impressive family-style presentation, serve the tetrazzini directly in the baking dish with a rustic wooden spoon. Or, for a dinner party, portion it out into individual ramekins topped with extra cheese and a sprinkle of parsley for a personalized touch that will dazzle your guests.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store them in an airtight container in the refrigerator where they will keep well for up to 3 days. The flavors actually have time to meld and deepen, making the next day’s serving even more delicious.
Freezing
Creamy Chicken Tetrazzini Recipe freezes beautifully. After baking, let it cool completely, then cover tightly with foil or plastic wrap and freeze for up to 2 months. This makes it a perfect make-ahead meal for busy days when you want homemade comfort fast.
Reheating
To reheat, thaw overnight in the refrigerator if frozen. Warm individual portions in the microwave or gently reheat the entire casserole in the oven at 350°F, covered with foil, until heated through. For that fresh-baked taste, uncover during the last 5 minutes to crisp up the topping again.
FAQs
Can I use rotisserie chicken for this recipe?
Absolutely! Rotisserie chicken is a fantastic shortcut for this Creamy Chicken Tetrazzini Recipe. It’s already cooked, flavorful, and saves you lots of prep time while still tasting amazing.
What can I add to make this dish more vegetable-packed?
Consider adding frozen peas, chopped spinach, or even steamed broccoli. Stir them in with the chicken and pasta so they heat through as the sauce simmers. These additions add vibrant color and extra nutrients effortlessly.
Is it okay to substitute the cheese in this recipe?
Yes! While Parmesan and mozzarella provide the classic flavors and textures, you can experiment with other Italian cheeses like provolone or fontina for a different twist. Just keep in mind the meltability and salt levels when substituting.
Can I make this recipe gluten-free?
Definitely. Use gluten-free pasta and substitute the all-purpose flour with a gluten-free flour blend or cornstarch to thicken the sauce. Just be sure to adjust the amount of thickener as needed to get that perfect creamy consistency.
What’s the best way to get a crispy topping?
For that irresistibly crunchy topping, sprinkle breadcrumbs mixed with a little melted butter over the mozzarella before baking. You can also broil the dish for 1 to 2 minutes at the end, but watch it closely so it doesn’t burn.
