Ingredients

Scale
  • 1 pound fettuccine pasta
  • 1 pound large shrimp, peeled and deveined
  • 4 tablespoons unsalted butter
  • 4 cloves garlic, minced
  • 1 1/2 cups heavy cream
  • 1 cup freshly grated Parmesan cheese, plus more for serving
  • 1/2 teaspoon salt, or to taste
  • 1/4 teaspoon black pepper, or to taste
  • Pinch of nutmeg (optional)
  • 2 tablespoons fresh parsley, chopped (for garnish)

Instructions

  1. Cook the fettuccine according to package directions until al dente. Reserve 1 cup of the pasta water before draining.
  2. While the pasta cooks, season the shrimp lightly with salt and pepper.
  3. Melt 2 tablespoons of butter in a large skillet over medium heat. Add the minced garlic and cook for about 1 minute until fragrant. Do not let the garlic brown.
  4. Add the seasoned shrimp to the skillet. Cook for 2-3 minutes per side until pink and opaque. Remove the shrimp from the skillet and set aside.
  5. Reduce the heat to low. Add the remaining 2 tablespoons of butter to the skillet. Whisk in the heavy cream. Heat gently, stirring often, until the sauce begins to simmer lightly.
  6. Remove the skillet from the heat. Gradually whisk in the grated Parmesan cheese until the sauce is smooth and creamy. Stir in the salt, pepper, and nutmeg, if using.
  7. Add the drained fettuccine to the skillet with the sauce. Toss to coat thoroughly. If the sauce seems too thick, add the reserved pasta water, one tablespoon at a time, until you reach a luscious consistency.
  8. Return the cooked shrimp to the skillet and toss gently to combine and heat through.
  9. Serve immediately, garnished with extra Parmesan cheese and fresh parsley.

Notes

  • For the creamiest sauce, use freshly grated Parmesan cheese; pre-shredded cheese contains anti-caking agents that can make the sauce grainy.
  • Do not boil the sauce once the cheese is added; keep the heat low to prevent the sauce from breaking.
  • If you prefer a richer flavor, substitute half of the heavy cream with half-and-half.
