Description

A cozy pasta dish with rich cream, warm spice, and sweet seafood, perfect for special occasions or weeknight dinners.


Ingredients

Scale
  • 12 oz fettuccine or linguine (dry)
  • 8 oz cooked lobster meat, roughly chopped (about 12 tails)
  • 8 oz lump crab meat, picked free of shells
  • 1 tbsp olive oil (for searing)
  • 4 tbsp unsalted butter
  • 1 tbsp olive oil (extra)
  • 4 cloves garlic, minced
  • 1 small onion, finely chopped (about 1/2 cup)
  • 1 tsp Cajun seasoning (adjust to taste)
  • 1/2 tsp smoked paprika (optional, for extra warmth)
  • 1/4 cup dry white wine or low-sodium chicken broth
  • 2 cups heavy cream
  • 1 to 1 1/2 cups freshly grated Parmesan cheese
  • Salt and black pepper to taste
  • Pinch of crushed red pepper flakes (optional)
  • 2 tbsp chopped fresh parsley (for garnish)
  • Lemon wedges (for squeezing)
  • Extra Parmesan (for serving)

Instructions

  1. Bring a large pot of salted water to a boil for the pasta. Chop lobster and pick crab meat free of shells. Grate the Parmesan and mince the garlic.
  2. Cook the pasta to al dente according to package directions. Reserve 1 cup of the pasta cooking water, then drain the pasta.
  3. Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add lobster and crab and sear for 1–2 minutes. Remove seafood to a plate.
  4. Lower heat to medium. Add butter and 1 tbsp olive oil to the same skillet. Sauté the onion until soft and translucent, about 3–4 minutes. Add minced garlic and cook until fragrant.
  5. Stir in Cajun seasoning and smoked paprika, then pour in white wine or broth and let it reduce by half.
  6. Pour in the heavy cream and bring to a gentle simmer. Let it thicken slightly for 3–5 minutes, stirring often, and season with salt, pepper, and red pepper flakes if using.
  7. Lower heat to medium-low and whisk in Parmesan until smooth. Adjust thickness with reserved pasta water if necessary.
  8. Return the warmed lobster and crab to the skillet and fold gently into the sauce. Add the drained pasta and toss to coat evenly. Heat through for 1–2 minutes.
  9. Taste and adjust seasoning. Serve immediately with chopped parsley, lemon wedges, and extra Parmesan.

Notes

Use unsalted butter to control salt. Fresh-grated Parmesan melts best. Avoid overcooking seafood to prevent it from becoming rubbery.
