How to Make Classic Chicken Tetrazzini Recipe
Step 1: Sauté the Aromatics
Start by preheating your oven to 375°F. In a large skillet, melt the butter with olive oil over medium heat. Add the finely chopped onion and sauté for about 3 minutes, just until it softens and becomes translucent. Next, stir in the minced garlic and sliced mushrooms, letting them cook for another 5 to 6 minutes. The mushrooms will release their juices and become beautifully tender, setting the stage for a deeply flavorful sauce.
Step 2: Make the Creamy Sauce
Once your veggies are fragrant and softened, sprinkle the flour over the mixture and stir constantly for about a minute. This forms a roux, which thickens your sauce and keeps it silky smooth. Gradually pour in the chicken broth, followed by the milk and heavy cream, whisking as you go. Let everything simmer gently for 5 to 6 minutes, until the sauce thickens to a luscious consistency. Stir in the grated Parmesan, nutmeg, salt, and pepper—these finishing touches add layers of flavor and a bit of complexity.
Step 3: Combine the Chicken and Pasta
Now, add your cooked chicken and al dente spaghetti right into the skillet with the sauce. Give everything a good toss, ensuring that every strand of pasta and piece of chicken is coated in that decadent, creamy mixture. You want the ingredients to be thoroughly combined so each bite is packed with flavor and texture.
Step 4: Assemble and Bake
Lightly grease a 9×13-inch baking dish and pour in your pasta-chicken-sauce blend, spreading it into an even layer. Sprinkle the shredded mozzarella cheese evenly over the top, then finish with a generous layer of breadcrumbs. This is what will create that irresistible, golden crust in the oven. Slide the dish onto the center rack and bake for 25 to 30 minutes, until the top is bubbly and perfectly golden.
Step 5: Rest and Garnish
Once the Classic Chicken Tetrazzini Recipe is bubbling and golden, remove it from the oven and let it rest for at least 5 minutes. This helps the sauce set and makes serving easier. Sprinkle with fresh chopped parsley if you like, for a burst of color and freshness right before bringing it to the table.
How to Serve Classic Chicken Tetrazzini Recipe
Garnishes
A sprinkle of chopped fresh parsley goes a long way in brightening up the rich flavors and adding a touch of color. For extra zing, try a light dusting of freshly grated Parmesan or a few cracks of black pepper on top just before serving. These little finishing touches make the Classic Chicken Tetrazzini Recipe look as good as it tastes.
Side Dishes
Pair this creamy casserole with a crisp green salad tossed in a tangy vinaigrette to cut through the richness. Steamed broccoli, roasted asparagus, or even a simple medley of sautéed vegetables are all wonderful complements. Warm, crusty bread or garlic knots are also fantastic for soaking up every bit of that dreamy sauce.
Creative Ways to Present
Serve your Classic Chicken Tetrazzini Recipe straight from the baking dish for a cozy, family-style meal, or portion it into individual ramekins for an elegant dinner party twist. You can even spoon it into hollowed-out bread bowls or serve it alongside mini Caesar salads for a fun, interactive presentation that will wow your guests.
Make Ahead and Storage
Storing Leftovers
Leftover Classic Chicken Tetrazzini Recipe can be stored in an airtight container in the refrigerator for up to 4 days. The flavors continue to meld, making each reheated serving just as satisfying as the first. Be sure to cool the casserole completely before transferring to the fridge for best results.
Freezing
This dish is a freezer-friendly superstar. After baking and cooling, wrap the casserole tightly in plastic wrap and foil, or transfer individual portions to freezer-safe containers. It will keep well in the freezer for up to 2 months. When you’re ready to enjoy, simply thaw overnight in the fridge.
Reheating
To reheat, cover the dish with foil and warm in a 350°F oven until heated through, about 20 to 25 minutes. For single servings, the microwave works beautifully—just add a splash of milk or broth to keep things creamy, and heat in 30-second bursts until piping hot.
FAQs
Can I substitute turkey for chicken in this Classic Chicken Tetrazzini Recipe?
Absolutely! Turkey is a wonderful swap—especially after the holidays when there’s plenty of leftover roast turkey on hand. The flavors and texture work perfectly, and you won’t need to change anything else in the recipe.
What kind of pasta works best if I don’t have spaghetti?
While spaghetti is classic, fettuccine, linguine, or even penne can work well. Just be sure to cook the pasta al dente so it holds up to the creamy sauce and baking.
Can I add vegetables to this Classic Chicken Tetrazzini Recipe?
Of course! Stir in peas, chopped spinach, or even steamed broccoli florets when combining the chicken and pasta. It’s a great way to sneak in extra veggies and color.
How do I make this recipe lighter?
To lighten things up, substitute half-and-half or even evaporated milk for the heavy cream, and use reduced-fat cheeses. The result is still creamy and delicious, but with less richness.
Can I assemble the casserole ahead of time?
Yes! You can assemble everything up to a day ahead, then cover tightly and refrigerate. When you’re ready, simply bake as directed, adding a few extra minutes to the cooking time if baking straight from the fridge.
