Description

This Creamy Spaghetti Sauce is a rich, smooth, and savory Italian-American sauce made with butter, garlic, heavy cream, Parmesan cheese, and simple seasonings. It’s a quick and versatile sauce that elevates ordinary spaghetti into a comforting and satisfying meal, perfect for busy weeknights or special dinners. This sauce pairs wonderfully with chicken, shrimp, mushrooms, or vegetables for added flavor and protein.


Ingredients

Pasta

  • 12 oz (340 g) spaghetti

Sauce

  • 2 tablespoons butter
  • 4 cloves garlic, minced
  • 2 tablespoons all-purpose flour
  • 2 cups heavy cream
  • 1 cup grated Parmesan cheese
  • ½ cup chicken broth (or pasta water)
  • 1 teaspoon Italian seasoning
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 2 tablespoons chopped fresh parsley

For Serving

  • Extra Parmesan cheese, for serving


Instructions

  1. Cook Spaghetti: Cook the spaghetti according to package directions until al dente. Reserve ½ cup of the pasta water before draining the pasta.
  2. Sauté Garlic: Melt the butter in a large skillet over medium heat. Add the minced garlic and cook for about 1 minute until fragrant but not browned.
  3. Make Roux: Stir in the flour and cook for another minute while whisking constantly. This will help thicken the sauce.
  4. Add Liquids: Slowly pour in the heavy cream and chicken broth while whisking continuously until the mixture is smooth and combined.
  5. Incorporate Cheese and Seasoning: Add the grated Parmesan cheese, Italian seasoning, salt, and black pepper. Stir until the cheese melts and the sauce becomes creamy and smooth.
  6. Simmer Sauce: Let the sauce simmer gently for 3 to 5 minutes, allowing it to thicken slightly and the flavors to meld.
  7. Toss Pasta in Sauce: Add the cooked spaghetti to the skillet with the sauce and toss until the pasta is evenly coated. Use reserved pasta water if the sauce needs thinning.
  8. Garnish and Serve: Garnish the dish with freshly chopped parsley and extra Parmesan cheese before serving warm.

Notes

  • Freshly grated Parmesan melts more smoothly than pre-shredded cheese, enhancing sauce texture.
  • For extra protein, add grilled chicken, shrimp, bacon, or sautéed mushrooms to the sauce.
  • To make a lighter version, substitute whole milk and a bit of cream cheese for the heavy cream.
  • Store any leftovers in an airtight container and refrigerate for up to 3 days.
