Step-by-Step Instructions

  1. Boil the Pasta: Bring a large pot of salted water to a rolling boil. Add 12 oz of fettuccine pasta and cook according to package directions until al dente (about 10 minutes). Reserve 1/2 cup of starchy pasta water, then drain the remaining water.
  2. Season the Shrimp: Pat 1 lb of peeled, deveined raw shrimp thoroughly dry with paper towels. Toss with 1 teaspoon Cajun seasoning, 1/2 teaspoon paprika, 1/2 teaspoon garlic powder, and black pepper.
  3. Sear the Shrimp: Melt 1 tablespoon of butter with 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the shrimp in a single layer and cook for 1.5 to 2 minutes per side until pink and opaque. Set shrimp aside on a plate.
  4. Sauté the Garlic: Turn heat down to medium. Melt 2 tablespoons of butter in the skillet and add 5 minced garlic cloves. Sauté for 1 minute until fragrant.
  5. Simmer the Cream Sauce: Pour in 1.25 cups of heavy cream and 1/4 cup of chicken broth. Simmer gently over medium-low heat for 3 to 4 minutes until slightly reduced.
  6. Combine and Toss: Stir in 1 cup of freshly grated Parmesan cheese until completely melted. Add cooked fettuccine and seared shrimp to the skillet. Toss to coat evenly, adding reserved pasta water by the tablespoon if needed to adjust the sauce thickness.
  7. Garnish and Serve: Top with freshly chopped parsley and red pepper flakes. Serve immediately while warm.Tip: Freshly grating Parmesan from a block ensures the cheese melts smoothly into the cream without clumping.

Recipe Variations

  • Tuscan Style: Fold in 1 cup of fresh baby spinach and 1/3 cup of chopped sun-dried tomatoes right before tossing with pasta.

  • Swap with Linguine or Tagliatelle: Fettuccine can easily be swapped with other long pasta varieties like tagliatelle or linguine.

Frequently Asked Questions

Can I use half-and-half instead of heavy cream? Heavy cream provides the thick, stable body required for a rich Alfredo sauce. Half-and-half can be used, but the sauce will be thinner and may require a light starch slurry to thicken.

How do I prevent overcooking the shrimp? Sear the shrimp over high heat for no more than 2 minutes per side, removing them from the heat as soon as they turn pink and opaque.
