Ingredients

Scale
  • 8 ounces thin spaghetti
  • 5 tablespoons butter (divided use)
  • 8 ounces sliced mushrooms
  • 1/4 cup thinly sliced green onions
  • 1 clove garlic, minced
  • 6 strips bacon, diced, cooked and drained
  • 2 teaspoons finely chopped fresh parsley
  • freshly ground black pepper
  • salt, to taste
  • 3 tablespoons all-purpose flour
  • 1 1/2 cups half-and-half or whole milk
  • 1/2 cup fresh grated Parmesan cheese, plus more for serving

Instructions

  1. Bring a large pot of water to a boil. Break the spaghetti into the boiling water and add about 1 teaspoon of salt. Cook following the package directions for timing. Drain the spaghetti in a colander and set aside.
  2. Meanwhile, heat 2 tablespoons of the butter in a heavy skillet over medium heat. Add the mushrooms and cook until tender, stirring frequently. Add the green onions and garlic to the mushrooms and cook for 2 minutes longer. Add the cooked bacon and stir to blend. Add the drained spaghetti; set aside.
  3. Melt the remaining 3 tablespoons of butter in a saucepan over medium-low heat. Stir in flour and cook for about 2 minutes, stirring constantly. Add the half-and-half or milk to the roux and cook until sauce is thickened and begins to bubble, stirring constantly. Stir the 1/2 cup of Parmesan cheese into the sauce.
  4. Add the sauce to the spaghetti mixture along with the fresh parsley. Toss to blend and add salt and pepper to taste.
  5. Transfer to a serving bowl and sprinkle with more Parmesan cheese.
