Ingredients

  • ½ cup panko bread crumbs
  • 1 ⅓ cups grated Parmesan cheese, divided
  • 5 tablespoons unsalted butter, divided
  • 12 ounces white mushrooms, sliced thin
  • salt
  • pepper
  • 1 medium onion, diced
  • 1 large carrot, diced
  • 1 clove garlic, minced
  • 2 tablespoons all-purpose flour
  • 2 cups whole milk
  • 1 (14.5-ounce) can low sodium chicken broth
  • ¼ cup dry white wine
  • 4 ounces cream cheese, cut into small pieces
  • ½ to ¾ pound spaghetti noodles
  • 4 cups cooked turkey meat, cut into bite-sized pieces
  • 2 cups frozen peas
  • 2 tablespoons unsalted butter, melted, for topping
  • 2 tablespoons chopped parsley for garnish, if desired
  • Hot sauce for serving if desired

Instructions

  • Preheat oven to 375 degrees F.
  • Fill a large pot with water and place over medium-high heat. Keep warm until ready to cook the pasta.
  • In a small bowl combine the bread crumbs with 1/3 cup of the grated Parmesan cheese.
  • In a large saucepan cook the mushrooms in 4 tablespoons butter over medium heat. Stir frequently until the mushrooms have released their liquid and then most of it evaporates.
  • Add the remaining 1 tablespoon butter, the diced onion and carrots. Sauté for about 5 minutes until the onions are just starting to soften. Add the minced garlic and cook until fragrant, about 30 seconds. Add the flour, and cook stirring constantly for about 3 minutes. Add the milk, broth and wine and bring the mixture to a boil. Simmer the sauce, stirring frequently, for about 5 minutes. Off heat, add the cream cheese, the remaining 1 cup Parmesan cheese, 1/4 teaspoon salt and 1 teaspoon black pepper. Stir just until lightly blended, cover and keep warm. The cheeses will continue to melt in the warm sauce.
  • Cook the spaghetti according to the package directions. Drain the pasta reserving 1 cup of the cooking liquid. Place the spaghetti back into the pot used to cook it in, add the mushroom sauce, turkey, and peas. Gently stir to combine. Add 1 or 2 tablespoons (or more) of the pasta water if needed to thin. Check seasonings and add more black pepper if desired.
  • Pour the mixture into a 3-quart lightly greased casserole dish or oven-proof skillet. Sprinkle the panko bread crumbs over the casserole and drizzle with 2 tablespoons melted butter. Bake until bubbling and the top is golden brown about 30 minutes.

Notes

Once assembled, the casserole can be wrapped tightly in plastic wrap, and aluminum foil and refrigerated or frozen until ready to bake. If frozen, allow the casserole to sit overnight in the refrigerator until mostly thawed, then bake until bubbly and warmed through.
Substitute egg noodles for the spaghetti if desired
Take care when adding salt. Parmesan adds a good salty bite so check seasoning before adding more than listed. Plenty of black pepper is fine however!
