Creamy Turkey Tetrazzini Recipe for Leftovers and Holiday Meals

Turkey tetrazzini is classic comfort food — creamy, savory, and full of flavor. This from-scratch version skips canned soups in favor of a garlicky white sauce enriched with dry white wine and grated Gruyère. Sun-dried tomatoes and peas add bursts of color and brightness while sautéed mushrooms and tender turkey give the casserole substance. A golden panko-Parmesan topping provides a satisfying crunch that balances the silky filling. It’s a cozy, make-ahead-friendly dish that’s perfect for turning holiday leftovers into a new family favorite.

Here’s Why This Turkey Tetrazzini Recipe Works

From-scratch sauce: A garlicky white sauce made with milk, cream, chicken broth, wine, and Gruyère delivers far better depth than canned shortcuts.

Well-balanced mix-ins: Sun-dried tomatoes lend tang, peas bring sweetness, mushrooms add earthiness, and turkey makes it hearty.

Creamy without heaviness: The sauce coats the pasta smoothly so the casserole feels rich but not greasy.

Crunchy topping: Panko mixed with Parmesan browns to a crisp finish that contrasts the creamy interior.

Great for leftovers: Shredded turkey blends easily into the sauce, making this ideal after holidays or for repurposing cooked poultry.

Recipe Tips

Undercook the pasta slightly: It will finish cooking in the oven while absorbing sauce, so aim for just shy of al dente.

Brown mushrooms in batches: Avoid crowding the pan so they caramelize and develop flavor.

Use a drinkable wine: Pick a dry white you’d enjoy drinking; if you prefer no alcohol, substitute extra chicken broth.

Let it rest: Allow the casserole to sit for about 10 minutes after baking so it sets for cleaner servings.

Prep ahead: Assemble up to 24 hours in advance (leave off the breadcrumb topping), refrigerate, then add the topping and bake when ready.

Warm the dairy: Slightly warming milk and cream before adding them to the roux helps keep the sauce smooth.

Servings: 8

Ingredients

  • 12 ounces pasta (your choice)
  • 1 tablespoon olive oil
  • 6 tablespoons butter, divided
  • 8 ounces fresh mushrooms, sliced
  • 1 onion, chopped
  • 4 garlic cloves, minced
  • ⅓ cup all-purpose flour
  • 2 cups whole milk
  • 1 cup heavy cream
  • 1 cup chicken broth
  • ½ cup dry white wine
  • 1 tablespoon fresh thyme leaves
  • Salt and pepper
  • 16 ounces cooked turkey, about 3 cups chopped, bite-size
  • 8 ounces sun-dried tomatoes, drained and roughly chopped
  • 12 ounces green peas, thawed
  • 6 ounces Gruyère cheese, grated

For the Topping

  • ⅓ cup grated Parmesan cheese
  • 1½ cups Panko bread crumbs

Instructions

  1. Preheat the oven to 350°F and grease a 9×13-inch casserole dish.
  2. Bring a large pot of salted water to a boil. Add the pasta and cook until just shy of al dente according to package directions. Drain and toss with the olive oil; cover and set aside.
  3. In a large skillet over medium heat, melt 1 tablespoon butter. Add mushrooms and cook until they release their liquid and it begins to evaporate. Add the chopped onion and cook until soft. Stir in garlic and cook 30 seconds more. Transfer to a plate and set aside.
  4. In the same skillet, melt the remaining butter over medium heat. Whisk in the flour and cook 2–3 minutes until lightly browned. Gradually whisk in the milk, cream, chicken broth, and wine. Bring to a gentle boil, then reduce heat to medium-low and simmer, stirring constantly, until the sauce thickens, about 8 minutes.
  5. Stir in the thyme leaves and season the sauce with salt and pepper to taste.
  6. Add the reserved pasta, mushroom-onion mixture, turkey, sun-dried tomatoes, and peas to the sauce, stirring until everything is evenly coated. Stir in the Gruyère until melted and combined.
  7. Transfer the pasta mixture to the prepared casserole dish and spread evenly.

For the Topping

  1. In a small bowl, combine the Panko bread crumbs and Parmesan. Sprinkle evenly over the tetrazzini.
  2. Bake for 30 minutes, until the edges bubble and the top is golden brown.
  3. Remove from the oven and let rest 10 minutes before serving.

Notes

Use up leftovers: Shredded turkey blends well into the sauce and stays tender.

Wine swap: A dry white wine adds depth; substitute extra chicken broth for an alcohol-free dish.

Cheese options: Gruyère gives a nutty richness, while Fontina, Swiss, or mozzarella are acceptable substitutes.

Make-ahead: Assemble without the topping and refrigerate up to 24 hours. Add crumbs and bake when ready.

Storage: Store covered in the fridge for up to 3 days; reheat gently in a 325°F oven until warmed through.

Freezing: Cool completely, wrap tightly, and freeze up to 2 months. Thaw overnight before reheating.
