What Is Turkey Tetrazzini?

Turkey Tetrazzini is a creamy, baked pasta dish that combines tender turkey, sautéed mushrooms, and a luscious cheese sauce. Typically made with spaghetti or linguine, it’s layered into a casserole and topped with breadcrumbs and Parmesan for a crispy finish.

The dish was named after Luisa Tetrazzini, a famed Italian opera singer, and first gained popularity in early 20th-century America. Though Italian in name, the recipe is a true American creation—comforting, hearty, and endlessly adaptable.

This “Authentic German” version elevates the classic with European ingredients and flavor profiles. Nutmeg adds a warm spice note, white wine brings brightness, and sour cream or heavy cream creates a velvety texture. It’s a cross-cultural celebration of flavor, blending the best of American tradition with German culinary finesse.

Step-by-Step Instructions

  1. Cook the pasta: Boil spaghetti or linguine until al dente. Drain and set aside.
  2. Sauté aromatics: In a large skillet, melt butter over medium heat. Add chopped onions and minced garlic, cooking until translucent.
  3. Add mushrooms: Stir in sliced mushrooms and cook until browned and tender.
  4. Make the roux: Sprinkle flour over the mixture and stir to coat. Cook for 1–2 minutes to eliminate raw flour taste.
  5. Deglaze with wine: Pour in white wine or dry sherry, scraping up any browned bits.
  6. Add broth and cream: Stir in chicken or turkey broth and heavy cream (or sour cream). Simmer until thickened, about 5–7 minutes.
  7. Season: Add salt, pepper, and a pinch of nutmeg.
  8. Combine: Fold in cooked turkey and pasta. Mix until evenly coated.
  9. Transfer to casserole: Pour mixture into a greased 9×13-inch baking dish.
  10. Top and bake: Sprinkle with Parmesan and breadcrumbs. Bake at 350°F (175°C) for 30–40 minutes, until bubbly and golden.
  11. Rest before serving: Let the casserole sit for 10 minutes to set the layers.

Tip: For extra crispiness, broil the top for 2–3 minutes at the end.

Turkey Tetrazzini is wonderfully flexible. Here are a few ways to make it your own:

  • Swap proteins: Use chicken instead of turkey for a similar flavor.
  • Change the pasta: Egg noodles, fusilli, or even penne work well.
  • Add veggies: Peas, carrots, spinach, or kale boost nutrition and color.
  • Go gluten-free: Use gluten-free pasta and flour for a celiac-friendly version.
