Best Chicken Tetrazzini Recipe From Scratch: Homemade Noodle Casserole Magic

This chicken tetrazzini delivers the best homemade comfort in every bite. A creamy sauce, tender chicken, and al dente noodles come together in a casserole that’s baked to golden perfection.

I developed this recipe to capture the rich, satisfying flavors of the classic dish without shortcuts. The sauce starts with a simple roux, then layers in mushrooms, sherry, and parmesan for depth.

What makes it special is the balance—creamy but not heavy, cheesy but not overpowering. The breadcrumb topping adds a crispy contrast to the velvety pasta below.

Serve it straight from the oven for a meal that feels like a warm hug. This is homemade magic at its finest.

Ingredients for Best Chicken Tetrazzini Recipe from Scratch

Classic comfort food starts with tender chicken, creamy sauce, and perfectly baked noodles. Nothing shortcut here.

The chicken is the foundation here. Boneless, skinless breasts stay tender and shred beautifully. For the best flavor, poach them in the chicken broth you’ll use in the sauce—double duty. Egg noodles are non-negotiable for that classic tetrazzini texture; Reames or Mueller’s are excellent brands. The Parmesan should be Parmigiano-Reggiano—grate it fresh from a wedge for superior melt and flavor.

Out of sherry? Dry white wine or a splash of apple cider vinegar works in a pinch. No whole milk? Half-and-half or cream makes it even richer (but heavier). Mushroom hater? Swap in diced bell peppers for color and crunch. For extra cheesiness, add Gruyère or sharp cheddar alongside the Parmesan. The breadcrumb topping can be buttered panko or crushed Ritz crackers for variety.

Casserole keeps covered in the fridge for 3-4 days. Reheat covered with foil at 350°F until warmed through. For make-ahead, assemble completely, refrigerate overnight, then bake as directed—add 10 extra minutes to the baking time. Freezes beautifully for up to 3 months.

Step-by-Step Instructions for Homemade Chicken Tetrazzini

Master this method for a creamy, comforting casserole that delivers on its promise of restaurant-quality results.

Step 1: Cook and Shred the Chicken Breast

Season the 1.5 lb chicken breast with ½ tsp salt and ½ tsp black pepper. Poach in the 2 cups chicken broth over medium heat for 12-15 minutes until the internal temperature reaches 165°F and the meat is no longer pink.

Remove the chicken from the broth and set aside to cool slightly. Reserve the broth for the sauce. Once cool enough to handle, shred the chicken into bite-sized pieces using two forks. This creates the perfect texture that melts into the creamy sauce.

Step 2: Prepare the Mushroom and Shallot Base

Melt 2 tbsp of the 0.5 cup unsalted butter in a large skillet over medium-high heat. Add the finely diced 1 whole shallot and cook for 2-3 minutes until translucent and fragrant.

Add the sliced 8 oz white mushrooms and cook for 5-6 minutes until they release their moisture and turn golden brown. Stir in the minced 3 cloves garlic cloves and cook for 30 seconds until fragrant. This builds the deep, savory foundation for your dish.

Step 3: Create the Creamy Sherry Sauce

In the same skillet, melt the remaining 0.5 cup unsalted butter over medium heat. Whisk in the 0.5 cup all-purpose flour to form a smooth roux. Cook for 1-2 minutes until the mixture turns a light golden color and smells nutty.

Slowly whisk in the reserved 2 cups chicken broth, 2 cups whole milk, and 0.25 cup dry sherry. Add the 1 tbsp Dijon mustard and remaining 1 tsp salt. Bring to a simmer and cook for 5-7 minutes until the sauce thickens enough to coat the back of a spoon.

Remove from heat and stir in ½ cup of the 1 cup Parmesan cheese until fully melted and smooth. Fold in the shredded chicken and 12 oz egg noodles, ensuring everything is well coated.

Step 4: Assemble and Bake with Crispy Topping

Transfer the mixture to a greased 9×13-inch baking dish. In a small bowl, combine the 0.75 cup panko breadcrumbs with the remaining ½ cup Parmesan cheese. Sprinkle this evenly over the casserole.

Bake at 375°F for 20-25 minutes until the sauce is bubbly and the topping is golden brown. Let it rest for 5 minutes before serving to allow the sauce to set slightly. This final step transforms the dish into a bubbling, golden masterpiece.

Make-Ahead Tips for best chicken tetrazzini recipe from scratch

Overnight Assembly

Prepare the entire casserole up to the baking step, then cover tightly with plastic wrap and refrigerate. I let it sit overnight to allow the flavors to meld deeply. In the morning, add 10 extra minutes to the baking time since it’s starting cold. 💡

Freezer-Friendly

Assemble the dish completely, wrap in heavy-duty foil, and freeze for up to 3 months. Thaw overnight in the fridge before baking. For best results, add 5-10 minutes to the baking time to ensure it’s heated through.

Pre-Cook Noodles

If making ahead, cook the 12 oz egg noodles just until al dente (about 1 minute less than package instructions). They’ll finish cooking in the oven, preventing a mushy texture when reheated.

Sauce Prep Tip

Make the sauce a day ahead and store it separately in the fridge. Reheat gently before combining with noodles and chicken. This prevents the noodles from absorbing too much liquid and becoming dry. ❄️

Topping Trick

Mix the 0.75 cup panko breadcrumbs and ½ cup Parmesan just before baking for maximum crispiness. If prepping ahead, store the topping mix in a separate bag to keep it dry and fresh.

Reheating Leftovers

Cover individual portions with a damp paper towel and microwave on 70% power for 2-3 minutes. For oven reheating, cover with foil and bake at 350°F for 15-20 minutes until bubbly.
