  • Stove Top
  • Oven


  • 2 cups Pappardelle or Fetuccine Noodles
  • 5 tablespoons Butter
  • 1 cup White mushrooms sliced
  • 1 cup Cooked Turkey Breast diced
  • 1 tablespoon Dried or Fresh Thyme
  • 3 tablespoons All Purpose Flour
  • 2 cups Milk
  • 1 cup Chicken Broth
  • salt and pepper to taste


  • Preheat the oven to 400°. Grease a 9-by-13-inch baking dish and set to the side.
  • Cook the pasta according to package directions until just barely al dente; drain.
  • Add 2 tablespoons butter to the skillet. Add the mushrooms and thyme; season with salt and pepper. Cook until the mushrooms start to soften, about 3 minutes. During the last minute of cooking, add the chopped turkey, mix well, and transfer to a bowl and set to the side.
  • Melt the remaining 3 tablespoons butter in the skillet. Whisk in the flour and cook for 1 minute. Whisk in the milk and broth and bring to a boil, then simmer for 2 to 3 minutes to thicken. Stir in ½ cup Parmesan, peas and carrots mix, and turkey. Season with salt and pepper if desired.
  • Add the pasta and cooked mushrooms/turkey to the sauce. Toss well to combine. Transfer the pasta mixture to the prepared baking dish.
  • Sprinkle with the remaining ½ cup Parmesan. Bake until the top is golden-brown and the sauce is bubbling, 12 to 15 minutes. Carefully, remove from the oven and serve immediately.


  • Vegetables - You can use frozen peas and carrots, fresh onions, mushrooms, even broccoli if you want.
  • Turkey - If you don't have leftover turkey, but still want to make this bake some skinless, boneless turkey breast and use that in replace of leftover turkey. 
  • Canned Soup - Some people like to use canned soup for turkey tetrazzini I prefer to make a homemade cream sauce. It takes an extra 5 minutes, but I promise it makes all the difference.
  • Substitution for Dairy - I have not tried making this recipe dairy free; however, you can substitute out the dairy for a dairy-free/plant based milk and butter.
  • Freezing - If you want to freeze some of this for an easy meal. Do not bake the dish. Instead add to a freezer safe container to bake for a future date
