Rich, velvety sauce clings to noodles and mushrooms in this ultimate comfort dish.

The mushrooms are the backbone here. Cremini (baby bella) mushrooms have deeper flavor than white button—look for firm caps with no slimy spots. I grab mine from Whole Foods or Trader Joe’s since they turn over stock quickly. For the chicken, rotisserie chicken is a lifesaver on busy nights (shred it while it’s warm). Poaching your own? Use the same broth for the sauce—double flavor. The Parmesan should be Parmigiano-Reggiano, not the pre-grated stuff.

No cremini? White button mushrooms work fine—they’re milder but still good. Short on time? Pre-sliced mushrooms from the grocery store save 10 minutes. For a lighter version, half-and-half instead of heavy cream still gives richness without the heaviness. No sherry? Dry white wine or extra broth works. The Worcestershire adds depth—if you’re avoiding it, a dash of soy sauce gets you close.

Assemble it a day ahead—bake straight from the fridge (add 10-15 minutes to cooking time). Leftovers keep 4-5 days in the fridge, freezes beautifully for 3 months. Reheat covered with foil to prevent drying.

Step-by-Step Instructions for Chicken Tetrazzini

Here’s my proven method for achieving that signature creamy texture and rich flavor in every bite.

Step 1: Prepare the Chicken and Noodles

Begin by cooking the 1.5 lb chicken breast until fully done, then shred it into bite-sized pieces. I like to poach mine in the chicken broth for extra flavor—simmer for 15-18 minutes until the internal temperature reaches 165°F.

While the chicken cooks, break the 12 oz spaghetti noodles into 2-inch pieces as specified. Cook them in salted boiling water for 2 minutes less than package directions—they’ll finish cooking in the oven. Drain and set aside.

Step 2: Create the Roux Base

In a large pot over medium heat, melt the 0.5 cup unsalted butter. Add the finely diced yellow onion and cook for 3-4 minutes until translucent. This builds the flavor foundation for your sauce.

Stir in the 0.5 cup all-purpose flour to form a smooth roux. Cook for 1-2 minutes until it turns a light golden color and smells nutty. The roux should bubble gently but not brown—this ensures your sauce stays creamy rather than grainy.

Step 3: Build the Creamy Sauce

Gradually whisk in the 2 cups whole milk and 2 cups chicken broth (the same broth you poached the chicken in for maximum flavor). Bring to a gentle simmer, stirring constantly, until the mixture thickens enough to coat the back of a spoon.

Reduce heat to low and stir in the 1 cup heavy cream, 1 cup parmesan cheese, 1 tbsp Dijon mustard, 1 tsp Worcestershire sauce, and 2 tbsp dry sherry. Season with 1 tsp salt and 0.5 tsp black pepper. Taste and adjust seasoning as needed.

Step 4: Combine All Components

Add the shredded chicken, cooked spaghetti, and sliced cremini mushrooms to the sauce. Fold everything together gently until evenly coated. The mushrooms should soften slightly in the hot sauce—this takes about 2-3 minutes.

Here’s the thing—this mixture should look rich and creamy. If it seems too thick, add a splash of warm milk or broth to reach your desired consistency. The sauce will thicken slightly as it bakes.

Step 5: Bake to Perfection

Transfer the mixture to a greased 9×13-inch baking dish. Bake at 375°F for 20-25 minutes until bubbly and golden brown on top. You’ll see the edges start to pull away from the sides of the dish when it’s ready.

Let it rest for 5 minutes before serving. This allows the sauce to set slightly, making it easier to serve neat portions. The top should have a beautiful golden crust while the inside remains creamy and comforting.
