what you'll need

  • 8 oz spaghetti or linguini
  • 1 stick unsalted butter
  • 1 medium onion diced
  • 8 oz button mushrooms sliced
  • 1 tsp fresh thyme leaves or 1/2 tsp dried
  • 3 cups leftover turkey shredded
  • 3 cloves garlic minced
  • 1/2 cup dry white wine
  • 1/4 cup all-purpose flour
  • 3 cups whole milk or half-and-half, room temperature
  • 2 1/2 tsp salt
  • 1 tsp pepper
  • 1 cup peas frozen
  • 3 Tbsp fresh parsley chopped
  • 1/3 cup Parmesan cheese grated
  • 1/3 cup breadcrumbs

let's do it

  • Preheat oven to 375 degrees and butter 9" x 13" baking dish; set aside.
  • Cook spaghetti or linguine according to directions on package. Rinse with cold water; set aside.
  • Melt butter in large skillet over medium-high heat. Add onions, mushrooms and thyme. Cook until most liquid from mushrooms has evaporated (5 minutes). Add turkey and garlic and cook 3 minutes more then add wine then cook until liquid has evaporated (3−4 minutes). Sprinkle flour over chicken and vegetables, stir to combine then cook for 30 seconds. Add milk then stir to dissolve flour completely, scraping brown bits from bottom of skillet.
  • Allow mixture to boil then immediately reduce heat to low. Season with salt and pepper and simmer 6−8 minutes—sauce will thicken slightly. Stir in cooked pasta, frozen peas and chopped parsley.
  • Pour mixture into prepared baking dish and top with grated Parmesan cheese. Bake uncovered 15−20 minutes until bubbly on sides and golden brown on top. Allow to cool 5 minutes before serving and enjoy!

One Last Thing

Choose button mushrooms that are firm and dry with few cracks—store in a paper bag in the fridge for up to one week.
