How to Make Chicken Tetrazzini Recipe
Step 1: Prepare the Pasta
Start by preheating your oven to 375°F (190°C) so it’s ready when your casserole is assembled. Cook the spaghetti according to the package instructions until it is al dente—not too soft, as it will finish cooking in the oven. Drain the pasta well and set it aside to keep warm. This foundational step ensures your noodles are perfectly tender with just the right bite.
Step 2: Sauté the Vegetables
In a large skillet, melt the butter over medium heat, allowing it to melt gently without browning. Add the finely chopped onion and cook it for 3 to 4 minutes until it softens and turns translucent. Next, stir in the minced garlic and sliced mushrooms. Sauté the mixture until the mushrooms release their moisture and start to brown beautifully, about 5 to 6 minutes. This step builds deep, savory flavors essential for the sauce.
Step 3: Make the Creamy Sauce
Sprinkle the all-purpose flour over the sautéed vegetables in the skillet, stirring constantly for one minute to cook out any raw flour taste. Gradually whisk in the chicken broth, whole milk, and heavy cream, ensuring everything combines smoothly. Bring this mixture to a gentle simmer and cook for 4 to 5 minutes until it thickens into a velvety sauce. This creamy base brings the entire Chicken Tetrazzini Recipe together in a luscious way.
Step 4: Combine Ingredients
Now it’s time to add the cooked chicken, frozen peas, grated Parmesan cheese, salt, black pepper, and a touch of ground nutmeg to the sauce. Stir everything thoroughly, then add the cooked spaghetti, tossing gently to coat all the noodles evenly with that flavorful sauce. This combination ensures each bite is perfectly balanced with creamy, savory, and slightly sweet elements.
Step 5: Bake to Perfection
Transfer the pasta mixture into a greased 9×13-inch baking dish, spreading it out evenly. Sprinkle the shredded mozzarella cheese over the top, followed by the breadcrumbs to create a golden, bubbly crust once baked. Place the dish in the oven and bake for 25 to 30 minutes until the cheese is melted and the topping turns a delicious golden brown. Let the dish rest for 5 to 10 minutes before serving to set and cool slightly.
How to Serve Chicken Tetrazzini Recipe

Garnishes
Fresh herbs like chopped parsley or thyme sprinkled on top brighten the rich flavors of Chicken Tetrazzini Recipe and add a fresh, colorful touch. For an extra cheesy finish, a light dusting of Parmesan just before serving works wonders. A squeeze of lemon juice can also add a subtle zing that cuts through the creaminess.
Side Dishes
Pair this dish with a crisp green salad tossed with a light vinaigrette to balance the richness beautifully. Roasted or steamed vegetables such as asparagus, green beans, or broccoli offer a fresh, vibrant contrast. For those craving more carbs, garlic bread or crusty rolls make a welcome companion for soaking up any remaining sauce.
Creative Ways to Present
For a charming presentation, serve in individual ramekins or small baking dishes for personal portions. Layer the pasta with alternating spoonfuls of cheese and breadcrumbs for a rustic, textured look. Garnish each portion with a sprig of fresh thyme or basil to elevate the dining experience to restaurant-quality in your own home.
Make Ahead and Storage
Storing Leftovers
This Chicken Tetrazzini Recipe stores wonderfully in the refrigerator. Keep leftovers tightly covered in an airtight container, and they will stay fresh for 3 to 4 days. When you’re ready to enjoy again, simply reheat and savor all those comforting flavors without missing a beat.
Freezing
You can freeze this dish if you want to prepare it ahead or save extra portions. Use a freezer-safe container and cover it well to prevent freezer burn. It will keep its quality for up to 2 months. When planning to bake after freezing, it’s best to thaw it overnight in the fridge for even reheating.
Reheating
For the best results, reheat leftovers in a preheated oven at 350°F (175°C) until warmed through, usually about 20 minutes depending on portion size. Cover with foil during heating to maintain moisture, uncovering in the last few minutes to refresh the crispy breadcrumb topping. Alternatively, a microwave works for quick reheating, but the oven method preserves the original texture beautifully.
FAQs
Can I use turkey instead of chicken in this recipe?
Absolutely! Turkey makes a fantastic substitute and adds its own mild, savory flavor. Just swap it in with the same quantity of cooked meat for a slightly different but equally tasty Chicken Tetrazzini Recipe.
Is there a way to make this recipe healthier?
Yes! You can use whole-wheat spaghetti for added fiber, reduce the amount of butter, or substitute half-and-half for the heavy cream. Adding extra vegetables like spinach or bell peppers also boosts nutrition while keeping it delicious.
Can this dish be made dairy-free?
To make this dairy-free, use plant-based butter and substitute the milk and cream with coconut milk or a creamy dairy-free alternative. Nutritional yeast can replace the cheese to give that cheesy flavor without dairy.
How do I know when the pasta is done?
Cooking the spaghetti al dente means it should be tender yet still firm to the bite. Follow the package instructions and taste a strand early to avoid overcooking since the pasta will finish cooking in the sauce during baking.
Can I add wine to the sauce?
Yes, adding a splash of dry white wine when cooking the mushrooms adds depth and a subtle tanginess that complements the creamy sauce beautifully. Just let the wine reduce before adding the flour to avoid a raw alcohol taste.

This Chicken Tetrazzini Recipe is a true crowd-pleaser that combines comforting textures and flavors in one satisfying dish.
