  • 7 tablespoons unsalted butter , divided
  • 1 pound cremini mushrooms , sliced
  • 1 cup diced shallots or onion
  • 2 cloves garlic , chopped
  • 1 teaspoon fresh thyme
  • 1/3 cup all purpose flour
  • 2 cups whole milk
  • 2 cups chicken stock
  • 1.5 cups heavy cream
  • 2-3 tablespoons dry sherry (depending on how much you want to taste it)
  • 1/8 teaspoon ground nutmeg
  • 1 cup grated Parmigiano Reggiano , divided
  • 3/4 cup frozen peas
  • 3 cups shredded cooked turkey breast (or chicken)
  • 1/4 cup chopped Italian parsley
  • 1/2 cup unseasoned Panko breadcrumbs
  • 12 ounces linguine , snapped in half and cooked until "al dente"
  • kosher salt and freshly ground black pepper


  • Preheat oven to 400 degrees F.  Butter a 4.8-qt (13x9) casserole dish. 
  • Melt 2 tablespoons of butter in a large pot over medium-high heat, until foaming subsides. Add mushrooms with 1/2 teaspoon salt and 1/4 teaspoon pepper, and cook until liquids are released and mostly evaporated, about 5 minutes. 
  • Add shallots and cook for about 3-4 more minutes, until mushrooms are beginning to brown. Stir in garlic and thyme and cook for 1 minute, until fragrant. Remove mixture from pan and set aside.
  • Melt 4 more tablespoons of butter in the empty pan. Stir in flour and cook for 2-3 minutes. Whisk in milk, stock, cream, sherry, nutmeg, 1 teaspoon kosher salt, and 1/2 teaspoon black pepper. Continue cooking, whisking, until the sauce is smooth, glossy, and coats the back of a spoon, about 5 minutes. 
  • Whisk in 3/4 cup Parmigiano Reggiano until smooth. Remove from heat and fold in sautéed mushrooms, peas, shredded turkey, and parsley. Season to taste with salt and pepper.
  • Stir in cooked linguine and pour into the prepared casserole dish.
  • Melt the remaining tablespoon of butter, stir in Panko breadcrumbs, the remaining 1/4 cup of parmesan, and 1/4 teaspoon black pepper. Sprinkle breadcrumb mixture on top of the Tetrazzini.
  • Place dish on a baking sheet and bake for 25 minutes, until bread crumbs are browned and sauce is bubbling. Watch the breadcrumbs, particularly around the 15-minute mark. If they're starting to brown too quickly, shield the top of the dish with a piece of foil.
  • Serve hot. The sauce will thicken further as the tetrazzini stands and cools.
