Description

This shrimp and crab pasta with creamy Cajun sauce is a bold, comforting seafood dish loaded with rich flavor and Southern spice. Juicy shrimp, tender crab meat, and al dente pasta are tossed in a smoky, creamy Cajun-spiced sauce for a restaurant-worthy dinner that’s surprisingly easy to make at home in under an hour.


Ingredients

  • 8 oz fettuccine or linguine pasta
  • 1 tablespoon olive oil
  • 2 tablespoons butter
  • 3 garlic cloves, minced
  • ½ onion, finely chopped
  • 1 lb shrimp, peeled and deveined
  • 6 oz lump crab meat (fresh or canned, drained)
  • 1½ tablespoons Cajun seasoning (adjust to taste)
  • 1 cup heavy cream
  • ½ cup chicken broth or seafood stock
  • ½ cup grated Parmesan cheese
  • 2 tablespoons fresh parsley, chopped
  • Salt and black pepper, to taste
  • Lemon juice, to finish (optional)

Instructions

  1. Cook pasta in salted boiling water until al dente. Reserve 1 cup of pasta water, drain, and set aside.
  2. In a large skillet, heat olive oil and butter over medium heat. Sauté garlic and onion until soft and fragrant.
  3. Add shrimp and cook 2–3 minutes per side until pink. Remove and set aside.
  4. Sprinkle Cajun seasoning into the skillet and stir well.
  5. Pour in the cream and broth; bring to a gentle simmer.
  6. Stir in Parmesan cheese and cook until sauce thickens slightly, about 3–5 minutes.
  7. Gently fold in crab meat and cooked shrimp, letting them warm through.
  8. Add cooked pasta and toss everything together. Use reserved pasta water as needed to loosen the sauce.
  9. Finish with parsley and a squeeze of lemon juice. Serve immediately.

Notes

  • Swap shrimp or crab for scallops or crawfish for variation.
  • Use half-and-half instead of cream for a lighter version.
  • For more spice, add cayenne pepper or hot sauce.
  • Penne or spaghetti also work well in place of fettuccine.
  • Make dairy-free by using coconut cream and dairy-free cheese.
