Equipment

  • Deep Skillet or Pot

Ingredients
  

Pasta & Sauce

  • 8 oz fettuccine or linguine Any long pasta works
  • 3 tbsp olive oil Butter may be substituted
  • 3 cloves garlic minced
  • 2 cups chicken or seafood broth Seafood broth intensifies flavor
  • 1 cup heavy cream Half-and-half can be used
  • 1 cup grated Parmesan cheese
  • salt & black pepper to taste
  • fresh parsley chopped, for garnish

Seafood

  • 1 lb large shrimp peeled & deveined
  • 1 cup lump crab meat drained & flaked

Instructions
 

  • Heat olive oil in a deep skillet or pot over medium heat. Add minced garlic and sauté for 30–40 seconds until fragrant.
  • Pour in the chicken or seafood broth and heavy cream. Stir well and bring to a gentle simmer to form the sauce base.
  • Add the fettuccine or linguine directly into the pot. Push the pasta down as it softens so it cooks evenly in the liquid.
  • Simmer for 10–12 minutes, stirring occasionally to prevent sticking. The sauce will thicken naturally as the pasta cooks.
  • Reduce heat and stir in the Parmesan cheese until melted and creamy.
  • Add shrimp and crab meat. Cook for 4–5 minutes until the shrimp turn pink and opaque. Fold gently to avoid breaking the crab.
  • Season with salt and black pepper. Garnish with fresh parsley and serve hot.

Notes

This dish is fast, luxurious, and perfect for weeknights. Add spinach or mushrooms for extra depth, or substitute half-and-half for a lighter version.
