Ingredients

• 12 oz (340 g) fettuccine or tagliatelle
• 1 lb (450 g) large shrimp, peeled and deveined
• 8 oz (225 g) lump crab meat, drained
• 2 tablespoons olive oil or butter
• 4 cloves garlic, minced
• 1 ½ cups chicken or seafood broth
• 1 cup heavy cream
• ¾ cup grated Parmesan cheese
• 1 teaspoon Italian seasoning or dried herbs
• Salt and freshly ground black pepper, to taste
• Chopped parsley or basil (for garnish)
• Red pepper flakes (optional, for spice)

Cooking the Seafood

1. In a large, deep skillet or wide pot, heat 1 tablespoon oil or butter over medium heat.
2. Add shrimp, season with salt, pepper, and a pinch of red pepper flakes if desired. Cook 2-3 minutes per side until pink and cooked through. Remove shrimp and set aside.

Preparing the Creamy Alfredo Sauce and Pasta

1. In the same pot, add remaining oil/butter and sauté garlic for 30 seconds until fragrant.
2. Pour in broth and bring to a simmer. Stir in heavy cream, Parmesan, and Italian seasoning; cook for 3-4 minutes until slightly thickened.
3. Add pasta to the pot along with a pinch of salt. Submerge pasta in the liquid; cook uncovered, stirring occasionally, until al dente and most liquid is absorbed (about 10-12 minutes).

Finish the Dish

Once pasta is cooked and creamy, fold in the cooked shrimp and crab meat. Gently toss to combine and heat through for 2 minutes.

Check seasoning and adjust with salt, pepper, or more cheese if desired. Garnish with chopped parsley or basil before serving.

Chef Tips

• Use fresh seafood for best flavor, but frozen is fine if thawed and drained thoroughly.
• Avoid overcooking the shrimp—they cook quickly and should stay tender.
• You can add a squeeze of lemon or a dash of hot sauce for extra brightness.
• If sauce becomes too thick, add a splash of warm broth or pasta water to loosen it.

Variations & Customizations

• Swap shrimp for scallops or cooked chicken for different proteins.
• Add sautéed vegetables like spinach, cherry tomatoes, or peas for extra freshness.
• Make it dairy-free with coconut cream and dairy-free cheese options.
• Spice things up with more red pepper flakes or chopped jalapeños.

Serving Ideas

Serve this decadent seafood pasta hot, topped with fresh herbs and extra Parmesan. Pair with garlic bread, a crisp green salad, or steamed vegetables for a complete meal.

Storage & Reheating

Store leftovers in an airtight container in the fridge for up to 2 days. Reheat gently on the stovetop, adding a splash of broth or milk to restore creaminess.
