Ingredients
  

For the Pasta

  • 12 oz 340g fettuccine
  • Salt for boiling water

For the Seafood Alfredo Sauce

  • 1 lb 450g shrimp (peeled & deveined)
  • 2 tbsp butter
  • 1 tbsp olive oil
  • 3 cloves garlic minced
  • 1 cup heavy cream
  • 1 cup whole milk
  • ¾ cup grated Parmesan cheese
  • 1 tbsp lemon juice
  • Salt and pepper to taste
  • Fresh parsley chopped (for garnish)

Instructions
 

Cook the Fettuccine:

  • Bring a large pot of salted water to a boil. Cook fettuccine according to package instructions. Drain and set aside.

Cook the Shrimp:

  • Heat olive oil and 1 tbsp butter in a large skillet over medium heat. Add shrimp and cook 2–3 minutes per side until pink. Remove and set aside.

Make the Alfredo Base:

  • In the same skillet, melt the remaining 1 tbsp butter. Add minced garlic and sauté for 30 seconds.

Add Cream & Milk:

  • Pour in the heavy cream and milk. Bring to a gentle simmer.

Add Cheese & Seasoning:

  • Stir in Parmesan, salt, pepper, and lemon juice. Simmer 3–4 minutes until slightly thickened.

Combine:

  • Add the cooked shrimp back into the sauce. Stir to coat.

Add Pasta:

  • Toss the fettuccine into the sauce until fully coated and glossy.

Serve:

  • Sprinkle with fresh parsley and extra Parmesan.

Notes

  • Don’t overcook shrimp: They become rubbery — remove as soon as they turn pink.
  • Cream thickness: If too thick, add a splash of milk; if too thin, simmer a bit longer.
  • Seafood variations: Add scallops, crab meat, or mussels for a richer seafood mix.
  • Make it lighter: Replace half the cream with milk or use half-and-half.
  • Best served immediately: Alfredo sauce thickens as it cools.
