How to Make chicken tetrazzini recipe
Making this dish is a simple process of boiling pasta, simmering a quick cream sauce, and then letting the oven do the work to melt everything together into a bubbly masterpiece. Follow these easy steps to get a perfect result every time.
Ingredients
- 1 pound spaghetti or linguine
- 3 cups cooked chicken, shredded or cubed
- 8 ounces sliced mushrooms (cremini or white button)
- 1/2 cup unsalted butter
- 1/4 cup all-purpose flour
- 2 cups chicken broth
- 1 cup heavy cream
- 1/2 cup sour cream
- 1/2 cup grated Parmesan cheese
- 1 cup shredded mozzarella cheese
- 1/2 cup frozen peas (optional)
- 2 cloves garlic, minced
- 1 small onion, finely diced
- 1 teaspoon dried thyme
- Salt and black pepper to taste
- 1/2 cup breadcrumbs (optional for topping)
Directions
Step 1: Cook the Pasta
Preheat your oven to 375°F (190°C). Bring a large pot of salted water to a boil. Cook the spaghetti according to the package instructions until it is just al dente. Drain the pasta and set it aside.
Step 2: Sauté Vegetables
In a large skillet or Dutch oven, melt the butter over medium heat. Add the diced onions and sliced mushrooms. Sauté for about 5 to 7 minutes until the mushrooms are browned and the onions are translucent. Stir in the minced garlic and thyme, cooking for another minute until fragrant.
Step 3: Prepare the Roux and Sauce
Sprinkle the flour over the sautéed vegetables and stir constantly for about 1 minute to cook out the raw flour taste. Slowly whisk in the chicken broth and heavy cream. Continue to simmer and stir until the sauce thickens and becomes smooth.
Step 4: Combine Ingredients
Remove the skillet from the heat. Stir in the sour cream, Parmesan cheese, and frozen peas. Add the cooked chicken and the drained pasta. Toss everything together until the noodles are thoroughly coated in the creamy sauce. Season with salt and pepper to taste.
Step 5: Bake the Casserole
Transfer the mixture into a greased 9×13 inch baking dish. Sprinkle the shredded mozzarella cheese and breadcrumbs evenly over the top. Bake for 25 to 30 minutes, or until the cheese is melted and the edges are bubbling and golden brown.
How to Serve chicken tetrazzini recipe
This dish is best served hot right out of the oven. Since it is quite rich and creamy, it pairs perfectly with a crisp green salad tossed in a light vinaigrette. You can also serve it alongside some steamed broccoli or roasted asparagus to add a bit of freshness to the meal. A slice of warm, crusty garlic bread is also a great addition to soak up any extra sauce.
How to Store chicken tetrazzini recipe
If you have leftovers, store them in an airtight container in the refrigerator for up to 3 to 4 days. When reheating, you might want to add a splash of milk or chicken broth before microwaving to help loosen the sauce, as the pasta tends to soak up the liquid as it sits. To freeze, wrap the unbaked casserole tightly in foil and store for up to 3 months. Thaw in the fridge overnight before baking as directed.
Expert Tips for Perfect chicken tetrazzini recipe
For the best results, do not overcook your pasta during the boiling stage. Since it will continue to cook in the oven, keeping it al dente ensures the noodles don’t become mushy. Additionally, using freshly grated Parmesan and mozzarella will give you a much better melt and flavor than the pre-shredded bags which contain anti-clumping agents.
Delicious Variations
You can easily customize this chicken tetrazzini recipe to suit your tastes. Swap the chicken for leftover turkey or even canned tuna for a different protein. If you want a bit of crunch, try topping the casserole with crushed Ritz crackers or fried onions instead of breadcrumbs. For a kick of heat, add a pinch of red pepper flakes to the sauce, or stir in some chopped bell peppers for extra color and nutrients.

Frequently Asked Questions
Q: Can I use a different type of pasta?
Yes, while spaghetti is traditional, you can use fettuccine, linguine, or even short shapes like penne or rotini. Just ensure you cook it to al dente.
Q: Is there a substitute for heavy cream?
You can use half-and-half or whole milk for a lighter version, though the sauce will be slightly less thick and rich.
Q: Can I make this dish ahead of time?
Absolutely. You can assemble the entire casserole, cover it, and keep it in the fridge for up to 24 hours before baking. You may need to add 5-10 minutes to the baking time if it is cold from the fridge.
Q: What can I use instead of mushrooms?
If you aren’t a fan of mushrooms, you can leave them out or replace them with chopped celery, carrots, or extra peas.
Q: Why did my sauce turn out thin?
The sauce will thicken as it bakes and cools slightly. If it seems too thin before baking, let it simmer a few minutes longer on the stove or add a little more cheese to help bind it.
