Chicken Tetrazzini Recipe: Mushroom and Parmesan Cream Pasta Delight

This pasta dish combines tender chicken, earthy mushrooms, and a rich parmesan cream sauce for a restaurant-quality meal at home.

I’ve refined this method to ensure the sauce clings perfectly to the noodles while keeping the chicken juicy. The key is using fresh ingredients and timing the cooking just right.

The result is a creamy, comforting dish with layers of flavor—savory chicken, umami mushrooms, and a velvety sauce that’s hard to resist.

Serve it hot, garnished with extra parmesan and parsley, for a satisfying dinner that feels special without the fuss.

Ingredients for Chicken Tetrazini

Restaurant-quality ingredients build layers of flavor in this creamy, comforting pasta dish.

The Parmesan cheese is non-negotiable for authentic flavor—Parmigiano-Reggiano from Whole Foods or a specialty cheese shop delivers the best results. Use a microplane for ultra-fine grating that melts seamlessly into the sauce. For the mushrooms, cremini or baby bella offer deeper flavor than white button. If using fresh pasta, reduce the cooking time by half and reserve extra starchy water for the sauce.

No dry sherry? Dry white wine works at a 1:1 ratio. For a non-alcoholic option, use additional chicken broth with a splash of apple cider vinegar. Fresh out of shallots? Substitute with half a small onion (about 1/4 cup diced). The Worcestershire sauce can be omitted, but a dash of soy sauce adds similar umami depth. Heavy cream can be replaced with half-and-half for a lighter version.

This casserole reheats beautifully—store leftovers in an airtight container in the fridge for up to 4 days. For longer storage, freeze portions for up to 3 months. The sauce will thicken as it cools; thin with a splash of milk or broth when reheating. Always bring to a full simmer to restore the creamy texture.

Step-by-Step Instructions for Chicken Tetrazzini

Master the technique with this precise method for a creamy, restaurant-quality pasta dish.

Step 1: Prepare the Chicken and Pasta Base

Begin by cooking the 1.5 lb chicken breast until fully done, then shred it into bite-sized pieces. I recommend poaching in the 1.5 cups chicken broth for added flavor, but any cooking method works as long as the meat is tender and juicy.

While the chicken cooks, bring a large pot of salted water to a boil and add the 12 oz spaghetti. Cook according to package directions until al dente, about 8-10 minutes. Drain the pasta, reserving ½ cup of the cooking water, and toss it with a bit of the 0.5 cup unsalted butter to prevent sticking. Break the spaghetti into thirds if desired for easier serving.

Step 2: Sauté the Aromatics and Mushrooms

In a large, deep skillet or Dutch oven, melt 2 tablespoons of the unsalted butter over medium heat. Add the 1 whole shallot, finely diced, and cook for 2-3 minutes until softened and translucent. Stir in the 3 cloves garlic cloves, minced, and cook for an additional 30 seconds until fragrant.

Add the 8 oz cremini mushrooms, sliced thinly, and cook for 5-6 minutes until they release their moisture and turn golden brown. Season with ½ tsp of the freshly ground black pepper and ½ tsp of the 1 tsp kosher salt. This builds the flavor foundation for the sauce.

Step 3: Create the Creamy Sauce

Reduce the heat to medium-low and add the remaining unsalted butter to the skillet. Once melted, whisk in the 0.33 cup all-purpose flour to form a roux. Cook for 1-2 minutes, stirring constantly, until the mixture turns a light golden color and smells nutty.

Slowly pour in the 2 cups whole milk and 1.5 cups chicken broth, whisking continuously to prevent lumps. Stir in the 1 tbsp Dijon mustard, 1 tsp Worcestershire sauce, and 0.25 cup dry sherry. Bring the mixture to a gentle simmer and cook for 5-7 minutes, stirring often, until it thickens enough to coat the back of a spoon.

Step 4: Finish and Combine All Elements

Remove the skillet from heat and stir in the 1 cup Parmesan cheese and 0.5 cup heavy cream until the cheese is fully melted and the sauce is smooth. Taste and adjust seasoning with the remaining ½ tsp kosher salt and ¼ tsp freshly ground black pepper if needed.

Add the shredded chicken and cooked spaghetti to the sauce, tossing everything together until evenly coated. If the mixture seems too thick, add a splash of the reserved pasta water to reach your desired consistency. The sauce should cling beautifully to the pasta and chicken.

Step 5: Garnish and Serve

Transfer the tetrazzini to a serving dish or individual plates. Garnish with the 0.25 cup fresh parsley, chopped, for a pop of color and freshness. For an extra touch, sprinkle additional Parmesan cheese on top if desired.

Let it rest for 5 minutes before serving to allow the flavors to meld together. The dish should be creamy, rich, and perfectly seasoned, with tender chicken and mushrooms throughout.

Flavor Customization for chicken tetrazini

Add a Spicy Kick

For a bolder flavor, stir in ½ tsp red pepper flakes when sautéing the aromatics. I also love adding 1 finely diced jalapeño to the mushrooms for fresh heat. A pinch of cayenne pepper in the sauce gives it a subtle warmth that builds with each bite. 🌶️

Herb Infusions

Fresh herbs elevate this dish beautifully. Try adding 1 tbsp chopped thyme or 1 tbsp rosemary to the mushrooms while cooking. For a brighter note, mix in 2 tbsp fresh basil at the end. Dried herbs work too—just use ⅓ the amount of fresh.

Cheese Variations

Swap half the parmesan for Gruyère or Fontina for a nutty, melty twist. I’ve had great results with sharp white cheddar for a more pronounced cheesy flavor. For extra creaminess, add ¼ cup cream cheese to the sauce while it’s still warm.

Vegetable Boost

Add ½ cup diced bell peppers or 1 cup spinach with the mushrooms for extra color and nutrients. For a heartier dish, include 1 cup roasted asparagus or zucchini. Just be sure to sauté any additional veggies until tender before mixing them in.

Sauce Adjustments

For a tangier sauce, add 1 tbsp lemon juice or 1 tsp lemon zest at the end. A splash of hot sauce or 1 tsp smoked paprika can add depth. If you prefer a thinner sauce, simply increase the broth by ¼ cup.

Protein Swaps

This recipe works well with turkey breast or rotisserie chicken for convenience. For a seafood twist, try shrimp or scallops—just cook them separately and fold in at the end to avoid overcooking. 💡
