Ingredients

  • 8 oz fettuccine pasta
  • 1 tablespoon salt (for boiling water)
  • 2 tablespoons butter (for seafood)
  • 6 oz cooked lobster meat
  • 6 oz lump crab meat
  • 2 tablespoons butter (for sauce)
  • 3 cloves garlic, minced
  • 1 1/2 cups heavy cream
  • 1 tablespoon Cajun seasoning (adjust to taste)
  • 3/4 cup grated Parmesan cheese
  • Salt and pepper to taste
  • 2 tablespoons chopped fresh parsley
  • 2 tablespoons reserved pasta water (as needed)

Instructions

  1. Step 1: Bring a large pot of salted water to a boil. Add the fettuccine and cook until al dente according to package directions. Reserve 1/2 cup of the pasta water, then drain and set pasta aside.
  2. Step 2: In a large skillet, melt 2 tablespoons of butter over medium heat. Add the lobster and crab meat and gently sauté for 2–3 minutes until warmed through. Remove from the skillet and set aside.
  3. Step 3: In the same skillet, melt the remaining 2 tablespoons of butter. Add the minced garlic and cook for about 30 seconds until fragrant. Pour in the heavy cream and bring it to a gentle simmer. Stir in the Cajun seasoning and cook for 3–4 minutes until the sauce begins to thicken.
  4. Step 4: Lower the heat and stir in the grated Parmesan cheese until fully melted and the sauce is smooth. Return the seafood to the skillet, add the cooked pasta, and toss everything to coat evenly. Add reserved pasta water a little at a time until the sauce reaches your desired consistency.
  5. Step 5: Finish by stirring in the chopped fresh parsley and seasoning with salt and pepper to taste. Serve immediately while hot and creamy.

Tips & Variations

  • For extra heat, add a pinch of cayenne pepper or more Cajun seasoning according to your preference.
  • Use fresh seafood if possible for the best flavor, or substitute with shrimp or scallops if preferred.
  • If the sauce gets too thick, thin it out with additional reserved pasta water or a splash of milk.
  • Garnish with extra Parmesan and parsley for a beautiful presentation.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently on the stovetop over low heat, adding a splash of cream or milk to loosen the sauce as needed. Seafood is best enjoyed fresh, so avoid reheating multiple times.
