  • 6 tablespoons butter, divided
  • 12 ounces white button mushrooms, cleaned and sliced
  • 3 tablespoons dry white wine
  • Kosher salt
  • 1 cup frozen peas
  • 2 tablespoons all-purpose flour
  • 2 cups turkey stock, very hot, preferably homemade (or chicken broth)
  • 1 cup whipping cream, very hot
  • ¼ teaspoon dried thyme, crumbled to release flavor
  • Pinch ground nutmeg
  • Fresh cracked black pepper, to taste
  • cup grated Parmesan, plus more to sprinkle on top
  • 3 cups cooked, skinless turkey, cut into bite-size pieces (or chicken)
  • 12 ounces spaghetti, linguine or egg noodles, cooked, drained


  • Heat oven to 375º. Butter a 13-by-9-inch baking dish and set aside.
  • In large skillet, melt 3 tablespoons butter over medium heat.  Add mushrooms, wine and a sprinkle of salt; cook and stir until softened.  Add peas, stir and cook a couple more minutes.  Set aside.
  • In large saucepan, melt 3 remaining tablespoons butter over medium-low heat.  Add the flour and stir and cook for about 3 minutes.  Whisk in about ½ cup hot broth until thick and smooth.  Add remaining hot stock and hot whipping cream.  Simmer until thick and smooth, about 10 minutes.  Add seasonings and Parmesan cheese, whisk until smooth and cheese has melted, taste for salt and pepper.
  • Mix in the diced turkey, reserved mushrooms and peas mixture, and cooked pasta noodles.  Combine well and pour into prepared casserole, top with a handful of shredded Parmesan.  Bake for 20 to 25 minutes until lightly browned and bubbling around the edges. 


  • Can substitute chicken for turkey, then you have chicken tetrazzini!
  • Try dry sherry instead of white wine, classic flavor combination with mushrooms and cream sauces.
  • Tarragon is another good herb to toss in, same amount as thyme.
  • No need to clean mushrooms under running water, just clean off any dirt with a paper towel. Mushrooms release a ton of liquid, don't add more to the party.
