- 1 lb cooked chicken breast or rotisserie chicken: Juicy and shredded to easily mingle with the sauce.

- 1 small onion, finely chopped: Provides a subtle sweetness and aromatics.
- 2 cloves garlic, minced: Adds a warm, savory punch essential to the dish’s depth.
- 8 oz sliced mushrooms: Earthy and tender, they elevate the texture and flavor profile.
- 1/4 cup all-purpose flour: Helps thicken the creamy sauce perfectly.
- 2 cups chicken broth: Forms the savory liquid base for the sauce.
- 1 cup heavy cream: Luxuriously creamy, it enriches the sauce for that deluxe feel.
- 1/2 cup whole milk: Balances the richness and keeps the sauce silky smooth.
- 1 teaspoon dried thyme: Brings a subtle herbal note that brightens the dish.
- 1/2 teaspoon dried rosemary: Adds woodsy aroma and depth.
- 1/2 cup grated Parmesan cheese: Sharp and nutty, it boosts the flavor and helps thicken the sauce.

How to Make Deluxe Chicken Tetrazzini Recipe
Step 1: Prepping the Oven and Pasta
Start by preheating your oven to 375°F (190°C) and greasing a 9×13-inch baking dish. While the oven warms, cook your spaghetti or egg noodles according to package instructions until al dente. This step is essential because perfectly cooked pasta delivers the right bite and absorbs the sauce beautifully without turning mushy later.
Step 2: Sautéing the Aromatics and Mushrooms
In a large skillet, melt the butter over medium heat, then add the finely chopped onion. Sauté until soft and fragrant, about 3 to 4 minutes. Next, toss in the minced garlic and sliced mushrooms. Cook until the mushrooms are tender and have released their moisture, around 5 to 7 minutes. This combination creates the flavor base, marrying sweetness and umami in the sauce.
Step 3: Thickening the Sauce
Sprinkle the flour evenly over the cooked vegetables and stir well to combine. Let it cook for 1 to 2 minutes to eliminate the raw flour taste – this little step really elevates the texture. Then, slowly pour in the chicken broth while stirring constantly to avoid lumps. Add the heavy cream, whole milk, dried thyme, dried rosemary, and season with salt and pepper. Continue stirring for 3 to 5 minutes until the sauce thickens slightly into a creamy dream.
Step 4: Combining Chicken and Cheese
Remove the sauce from heat, then stir in your shredded chicken, Parmesan cheese, and half of the mozzarella. This imparts that luscious cheesy creaminess that makes this dish a true comfort meal superstar. Mixing everything well ensures each bite bursts with layered flavors.
Step 5: Bringing It All Together
Add the cooked pasta to the skillet, tossing everything until the noodles are evenly coated with the creamy sauce. Transfer this mixture into your prepared baking dish and spread it out smoothly. This is where you just know it’s starting to come together into something magical.
Step 6: Adding the Finishing Touches
Sprinkle the remaining mozzarella on top, and if you love a bit of crunch, add in the bread crumbs. This topping will turn golden and slightly crispy in the oven, balancing the creaminess perfectly.
Step 7: Baking Your Deluxe Chicken Tetrazzini Recipe
Pop your casserole into the oven and bake for 25 to 30 minutes, until the top is bubbly and golden brown. For those who adore an extra-crisp topping, a quick 1 to 2-minute broil at the end seals the deal. Let the casserole rest a few minutes after baking so it settles before serving.

Freezing
This dish freezes beautifully. To freeze, bake as directed but undercook by about 5 minutes to avoid sogginess upon reheating. Cool completely, then cover tightly with foil or place in a freezer-safe container. It will keep well for up to 2 months.
Reheating
Reheat your Deluxe Chicken Tetrazzini Recipe in the oven at 350°F (175°C) for about 20 minutes, covered with foil to prevent drying out, removing the foil at the last 5 minutes to crisp the topping. For a quicker method, use the microwave on medium power, stirring occasionally for even heating.
FAQs
Can I use leftover chicken for this Deluxe Chicken Tetrazzini Recipe?
Absolutely! In fact, leftover roasted or rotisserie chicken works perfectly and saves time without compromising flavor.
What kind of pasta works best in tetrazzini?
Spaghetti or egg noodles are traditional and work best as they hold the creamy sauce well while staying tender but firm.
Is it necessary to add bread crumbs on top?
While optional, bread crumbs add a delightful crunch and contrast to the creamy casserole, making it worth including if you enjoy textural variety.
Can I make this recipe dairy-free or lower in fat?
For dairy-free options, substitute heavy cream and milk with plant-based creamers and use vegan cheese alternatives, though the dish will differ slightly in richness.
How do I prevent the pasta from becoming mushy?
Cooking the pasta just to al dente and not over-stirring the casserole before baking helps keep the noodles firm and prevents mushiness.
