Ingredients

Scale

Pasta

  • 12 ounces linguine or fettuccine pasta

Shrimp

  • 1 pound large shrimp, peeled and deveined
  • 2 tablespoons olive oil, divided
  • 2 tablespoons butter
  • 45 garlic cloves, minced
  • 2 tablespoons Cajun seasoning, divided (1 tbsp for shrimp, 1 tbsp for sauce)
  • Salt and black pepper, to taste

Sauce

  • 2 tablespoons tomato paste
  • 1 cup chicken broth
  • 1 cup heavy cream
  • 1/2 cup freshly grated Parmesan cheese, plus more for serving
  • 1/4 cup fresh parsley, chopped, plus more for garnish

Instructions

  1. Cook the Pasta and Reserve Water: Bring a large pot of salted water to a rolling boil. Add the linguine or fettuccine and cook according to package directions until al dente. Before draining, scoop out and reserve at least 1 cup of the starchy pasta cooking water. Drain the pasta and set aside.
  2. Cook the Shrimp: While the pasta cooks, pat the shrimp dry with paper towels. Season them generously with 1 tablespoon Cajun seasoning, salt, and black pepper. Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add shrimp in a single layer and cook for 1-2 minutes per side until pink and opaque. Remove shrimp from skillet and set aside to avoid overcooking.
  3. Build the Flavorful Sauce Base: Lower heat to medium. Add remaining 1 tablespoon olive oil and butter to the same skillet. When butter melts, add minced garlic and cook for 30-60 seconds until fragrant without browning. Stir in tomato paste and cook for 1 minute, pressing it against the pan bottom to deepen flavor.
  4. Concentrate and Thicken the Sauce: Pour in the chicken broth and bring to a gentle simmer while scraping up browned bits from the skillet. Let the broth reduce by about one-third over 3-5 minutes. This intensifies flavors and creates a robust sauce base.
  5. Creamy Perfection: Reduce heat to low. Stir in heavy cream and half of the grated Parmesan cheese. Simmer gently for 2-3 minutes, stirring constantly, until the sauce thickens and coats the back of a spoon. Adjust sauce consistency by whisking in reserved pasta water as needed, or continue simmering to reduce further.
  6. Combine and Coat: Add cooked pasta directly into the sauce. Toss well to coat every strand thoroughly. Gently fold in the cooked shrimp, ensuring even distribution.
  7. Finish and Serve: Stir in remaining Parmesan cheese and fresh chopped parsley. Toss everything until warmed through. Taste and adjust seasoning with salt, pepper, or more Cajun seasoning if desired. Plate immediately and garnish with extra parsley and a crack of black pepper for a beautiful presentation.

Notes

  • Reserving starchy pasta water and reducing chicken broth are essential steps to achieve a thick, non-watery sauce.
  • Do not overcook the shrimp; they only need 1-2 minutes per side until just pink and opaque for tender bites.
  • Adjust Cajun seasoning to your spice preference; start with 2 tablespoons total and add more if desired.
  • Fresh parsley adds a bright, herbaceous finish—feel free to add more for garnish.
