Description

A luxurious yet easy one-pot dish that combines shrimp and lump crab in a rich, creamy Alfredo sauce. Perfect for family dinners, potlucks, and special occasions.


Ingredients

Scale
  • 1620 large shrimp, peeled and deveined
  • 8 oz fresh lump crab meat
  • 34 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 4 cloves garlic, minced
  • 1 small shallot, finely chopped (or mild onion)
  • 1/3 cup dry white wine (or seafood stock)
  • 1 cup heavy cream
  • 1/2 cup whole milk
  • 1 cup freshly grated Parmesan cheese
  • Zest and juice of 1 lemon
  • Fresh parsley, chopped
  • Pinch of red pepper flakes
  • Salt and freshly ground black pepper
  • Pasta of choice (fettuccine or linguine), or cauliflower rice

Instructions

  1. Prepare the pasta: Bring a large pot of salted water to boil, and cook the pasta one minute short of package directions. Drain and reserve 1 cup of pasta water.
  2. Sear the shrimp: Heat a wide skillet over medium-high heat, and add olive oil and 1 tablespoon of butter. When the butter foams, add shrimp in a single layer, sear for 1-2 minutes per side until pink and opaque, then set aside.
  3. Sweat aromatics: Reduce heat to medium. Add remaining butter, shallot, and garlic; sauté until fragrant and translucent, about 2 minutes.
  4. Deglaze the pan: Pour in white wine, scrape up browned bits, and cook until reduced by half.
  5. Build the sauce: Add heavy cream and milk, bring to a gentle simmer, and whisk in Parmesan until smooth. Season with lemon zest, lemon juice, salt, pepper, and red pepper flakes.
  6. Finish with seafood: Fold in crab meat gently and return shrimp to skillet. Warm everything without boiling.
  7. Emulsify and bind: Toss the drained pasta into the skillet with a splash of reserved pasta water. Stir until the sauce clings to the pasta. Stir in chopped parsley and a knob of cold butter for shine.
  8. Serve immediately: Plate with extra Parmesan, parsley, and a squeeze of lemon. Enjoy with crusty bread.

Notes

Adjust cream and milk for desired richness. Reserve pasta water to adjust sauce consistency if needed. Taste as you season.
