What is Chicken Tetrazzini?
Chicken Tetrazzini is a classic Italian-American pasta dish, renowned for its luxurious creaminess and comforting qualities. Named after the famous Italian opera singer Luisa Tetrazzini, this casserole typically features diced poultry (most commonly chicken or turkey) and mushrooms in a rich, buttery, and cheesy cream sauce, often infused with sherry or wine, all tossed with spaghetti or another pasta shape. The entire concoction is then baked until golden brown and bubbly. Our easy version simplifies the traditional recipe without sacrificing any of that beloved rich flavor, making it accessible for home cooks seeking a hearty and satisfying meal without extensive effort.

Frequently Asked Questions About Chicken Tetrazzini
Can I add other vegetables to this recipe?
Absolutely! The beauty of Tetrazzini is its versatility. While peas are a classic addition, feel free to substitute or add any of your favorite frozen vegetables. Broccoli florets, diced carrots, corn, or even sliced bell peppers would be delicious. For fresh vegetables, consider sautéing them alongside the onion to ensure they soften properly before baking.
I don’t like cream of mushroom soup, can I use another?
Yes, certainly! While cream of mushroom soup contributes to the traditional flavor profile, many people (including myself) find it to be quite subtle in the final dish. If you’re concerned or simply prefer alternatives, you can easily substitute it with cream of celery soup, cream of chicken soup, or even cream of cheddar soup. For a fresher, homemade taste and to avoid canned soups entirely, you can also prepare your own Homemade Cream of Mushroom Soup or Homemade Cream of Chicken Soup from scratch.
Can I use a different pasta?
Spaghetti is traditionally used for Tetrazzini, giving it that classic long-noodle appeal. However, feel free to experiment with other pasta types. Fettuccine works wonderfully for a similar long-strand experience. For a heartier, easier-to-eat casserole, short pastas like rotini, penne, or even elbow macaroni are excellent choices that hold the creamy sauce beautifully.
What other cheese can I use?
While mozzarella provides a fantastic melt and mild flavor, Tetrazzini is very adaptable to different cheeses. Some other varieties that I’ve tried and loved include: sharp cheddar, Colby Jack, Monterey Jack, pepper jack (for a slight kick), fontina, smoked gouda, and gruyere. For the best melt and creamiest texture, always opt for freshly grated cheese rather than pre-shredded varieties, as they contain anti-caking agents that can hinder smooth melting.
What chicken is the best to use?
This recipe shines when using pre-cooked chicken. My top recommendations are leftover cooked chicken from a previous meal or a convenient store-bought rotisserie chicken. Both options save significant preparation time. If you don’t have chicken, don’t worry! Leftover cooked turkey or even ham can be fantastic substitutes, adding their own unique flavors to the Tetrazzini.
How do I store leftovers and reheat?
Storing leftovers is simple. Transfer the cooled Tetrazzini to an airtight container or cover the baking dish tightly with plastic wrap. It will keep well in the refrigerator for up to 3 days. For longer storage, Tetrazzini freezes beautifully! Place it in a freezer-safe container or wrap the entire baking dish first in plastic wrap, then in aluminum foil. It can be frozen for up to 3 months. To defrost, transfer it to the refrigerator overnight until thawed. Reheat individual portions in the microwave until heated through, or for a larger portion, bake in a preheated oven at 350°F (175°C) until bubbly and warm, covering loosely with foil if the top starts to brown too much.

Ingredients for Easy Chicken Tetrazzini
Gathering your ingredients is the first step to creating this delectable casserole. You’ll find most of these are common pantry staples, making this a convenient and economical choice for dinner:
- 16 ounces spaghetti noodles (1 box)
- 4 tablespoons salted butter
- 1 small sweet onion, small-diced
- 4 cloves garlic, minced
- ¼ cup all-purpose flour
- 2 cups milk (whole or 2% recommended for creaminess)
- 1 cup unsalted chicken stock
- 2 (10.5 ounce) cans cream of mushroom soup
- 2 cups shredded cooked chicken
- 1 cup frozen peas
- 1 cup sour cream
- 1 teaspoon dried parsley flakes, plus more for garnish (optional)
- ½ teaspoon kosher salt
- ½ teaspoon black pepper
- 2 cups shredded mozzarella cheese

How to Make Easy Chicken Tetrazzini: Step-by-Step
Step 1: Prep and Pasta
Preheat your oven to 350°F (175°C). Lightly spray a 9×13-inch baking dish with cooking spray and set it aside. Cook the spaghetti noodles according to the package directions until al dente. Drain the noodles thoroughly and set them aside. Over medium heat, melt the butter in a large pot or Dutch oven.

Step 2: Sauté Aromatics
Once the butter is melted, add the diced sweet onion to the pot. Cook the onion, stirring occasionally, until it becomes soft and translucent, which usually takes about 10 minutes. This step builds the flavor base for your sauce.

Step 3: Create the Roux
Add the minced garlic to the pot with the softened onions. Stir constantly for about 30 seconds until the garlic becomes fragrant. Be careful not to burn it. Then, stir in the all-purpose flour and cook for 1 minute, stirring constantly, to create a roux that will thicken your sauce.

Step 4: Whisk in Liquids
Slowly stream in the milk and chicken stock, continuously whisking to prevent any lumps from forming. Continue to whisk until the sauce begins to thicken slightly and is smooth.

Step 5: Add Creamy Elements
Stir in the cream of mushroom soup (or your chosen substitute) and whisk until it is thoroughly combined into the sauce. This adds an extra layer of richness and depth to the Tetrazzini base.

Step 6: Combine Remaining Fillings
Add the shredded cooked chicken, frozen peas, sour cream, dried parsley flakes, kosher salt, and black pepper to the pot. Stir everything together thoroughly until all the ingredients are well combined and coated in the creamy sauce.

Step 7: Mix with Pasta
Finally, add the cooked and drained spaghetti noodles to the pot. Gently toss the noodles with the rich, creamy chicken mixture until they are thoroughly coated in the sauce. Ensure every strand is bathed in flavor.

Step 8: Bake and Serve
Pour the entire mixture into your prepared 9×13-inch baking dish, spreading it evenly. Generously top the casserole with the shredded mozzarella cheese. Bake uncovered for 30-35 minutes, or until the Tetrazzini is bubbly around the edges and the cheese on top is melted and lightly golden. For an extra golden-brown crust, you can carefully turn on the broiler for the last few minutes, but watch it very closely to prevent burning.

Remove from the oven, allow it to cool slightly, and if desired, garnish with a sprinkle of fresh or dried parsley before serving. Enjoy this hearty and flavorful meal!


Pro Tips for the Best Chicken Tetrazzini
- Al Dente Pasta is Key: Cook your spaghetti a minute or two less than the package directions suggest. Since it will bake in the oven, it will continue to cook and absorb the sauce, preventing it from becoming mushy.
- Freshly Grated Cheese: As mentioned in the FAQ, grating your own cheese makes a noticeable difference. It melts smoother and provides a creamier texture compared to pre-shredded cheese, which often contains anti-caking agents.
- Don’t Skimp on the Whisking: When adding the milk and chicken stock to the roux, continuous whisking is crucial to create a smooth, lump-free sauce base. This ensures your Tetrazzini will have that velvety texture.
- Enhance the Sauce: For an even richer sauce, consider replacing half of the milk with half-and-half or heavy cream. A splash of dry sherry or white wine (about ¼ cup) added with the chicken stock can also elevate the flavor profile, giving it a more sophisticated touch.
- Season to Taste: Always taste your sauce before mixing in the pasta. Adjust salt and pepper as needed. Remember, the chicken stock and canned soups can contribute some sodium, so season incrementally.
- Customizing Vegetables: If adding other raw vegetables (like mushrooms, bell peppers, or carrots), sauté them with the onion and garlic until tender-crisp before proceeding with the flour, ensuring they cook through evenly in the final bake.
Serving Suggestions
Chicken Tetrazzini is a complete meal on its own, packed with protein, carbs, and vegetables. However, a few simple sides can perfectly complement its rich flavors and creamy texture:
- Fresh Green Salad: A crisp salad with a light vinaigrette offers a refreshing contrast to the hearty casserole.
- Garlic Bread or Crusty Rolls: Perfect for soaking up every last bit of that delicious creamy sauce.
- Steamed Green Beans or Asparagus: These add a vibrant color and a healthy, tender-crisp element to your meal.
- Roasted Vegetables: A medley of roasted broccoli, cauliflower, or carrots provides another layer of flavor and nutrition.
