So, ditch the frozen dinners and get ready to create a homemade Chicken Tetrazzini that will become a family favorite for generations to come.
Why This Recipe Works
This isn’t just another Chicken Tetrazzini recipe. It’s a meticulously crafted formula designed for maximum flavor and texture. Here’s why it works so well:
- The Sherry Secret: A splash of dry sherry adds a depth of flavor that elevates the sauce from ordinary to extraordinary. It complements the mushrooms beautifully and adds a subtle warmth that’s simply irresistible.
- Perfectly Cooked Pasta: Overcooked pasta is the enemy of any good casserole. We’ll guide you on how to cook your pasta al dente, ensuring it maintains its texture and integrity throughout the baking process.
- Creamy, Not Greasy Sauce: We use a combination of butter, flour, chicken broth, and cream cheese to create a sauce that’s rich and flavorful without being overly heavy or greasy. The cream cheese adds a tangy note that balances the richness perfectly.
- Flavorful Chicken: We recommend using leftover roasted chicken or rotisserie chicken for convenience and flavor. The already cooked chicken adds a depth of savoriness that’s hard to beat. However, if you don’t have any on hand, we’ll provide instructions on how to cook chicken specifically for this recipe.
- Generous Parmesan: Parmesan cheese is the star of the show, adding a salty, nutty, and umami-rich flavor that ties everything together. We use it both in the sauce and as a topping for a truly cheesy experience.
Ingredients
- Pasta: 1 pound spaghetti, linguine, or fettuccine
- Chicken: 3 cups cooked, shredded chicken (about 1.5 pounds)
- Butter: 6 tablespoons unsalted butter, divided
- Mushrooms: 8 ounces cremini mushrooms, sliced
- Shallot: 1 medium shallot, finely chopped
- Garlic: 2 cloves garlic, minced
- Flour: 1/4 cup all-purpose flour
- Chicken Broth: 3 cups low-sodium chicken broth
- Dry Sherry: 1/4 cup dry sherry
- Cream Cheese: 4 ounces cream cheese, softened
- Heavy Cream: 1/2 cup heavy cream
- Parmesan Cheese: 1 cup grated Parmesan cheese, divided
- Salt and Pepper: To taste
- Fresh Parsley: 2 tablespoons chopped fresh parsley, for garnish (optional)

Instructions
- Preheat and Prepare: Preheat oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish.
- Cook the Pasta: Cook the pasta according to package directions until al dente. Drain and set aside.
- Sauté the Mushrooms: Melt 2 tablespoons of butter in a large skillet over medium heat. Add the mushrooms and cook until softened and lightly browned, about 5-7 minutes. Add the shallot and garlic and cook for another minute until fragrant. Remove the mushrooms from the skillet and set aside.
- Make the Sauce: In the same skillet, melt the remaining 4 tablespoons of butter. Whisk in the flour and cook for 1-2 minutes, stirring constantly, to create a roux. Gradually whisk in the chicken broth and sherry until smooth. Bring to a simmer and cook for 5-7 minutes, or until the sauce has thickened slightly.
- Incorporate the Cream Cheese: Reduce the heat to low and whisk in the softened cream cheese until smooth and fully incorporated. Stir in the heavy cream and 1/2 cup of the Parmesan cheese. Season with salt and pepper to taste.
- Combine Ingredients: Add the cooked pasta, shredded chicken, and sautéed mushrooms to the sauce. Toss to coat evenly.
- Assemble and Bake: Pour the mixture into the prepared baking dish. Sprinkle the remaining 1/2 cup of Parmesan cheese over the top. Bake for 20-25 minutes, or until the casserole is heated through and the cheese is melted and lightly golden brown.
- Rest and Serve: Let the casserole rest for 5-10 minutes before serving. Garnish with fresh parsley, if desired.
Tips for Success
- Don’t Overcook the Pasta: Al dente pasta is crucial for preventing a mushy casserole. Err on the side of undercooking rather than overcooking.
- Use High-Quality Ingredients: The better the ingredients, the better the flavor. Opt for fresh mushrooms, good quality Parmesan cheese, and flavorful chicken broth.
- Taste and Adjust Seasoning: Taste the sauce before adding the pasta and chicken and adjust the seasoning as needed. Don’t be afraid to add more salt, pepper, or even a pinch of red pepper flakes for a little kick.
- Make Ahead Option: You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Add an extra 5-10 minutes to the baking time if baking from cold.
- Chicken Cooking Options: If you don’t have leftover chicken, you can poach or bake chicken breasts specifically for this recipe. Poaching results in very tender chicken. Baking requires seasoning the breasts and baking at 375F until the internal temperature reaches 165F.
Storage Instructions
Refrigerating: Store leftover Chicken Tetrazzini in an airtight container in the refrigerator for up to 3-4 days. Reheat in the oven at 350°F (175°C) until heated through, or in the microwave in 1-2 minute intervals, stirring occasionally.
Freezing: While Chicken Tetrazzini can be frozen, the texture may change slightly upon thawing. The sauce may become a bit grainy. To freeze, let the casserole cool completely. Cut into portions and wrap tightly in plastic wrap, then place in a freezer-safe bag or container. Freeze for up to 2-3 months. Thaw in the refrigerator overnight before reheating as directed above.
