Cook the pasta

• Bring a large pot of salted water to a boil.
• Cook the fettuccine until al dente, then drain, reserving a little pasta water.

Sear the shrimp

• Melt half the butter in a frying pan over medium-high heat.
• Add the shrimp and cook until pink and opaque on both sides.
• Season with salt and pepper, then set the shrimp aside.

Make the Alfredo sauce

• Melt the remaining butter in the same pan and sauté the garlic until fragrant.
• Pour in the cream and simmer gently.
• Stir in the parmesan until the sauce is smooth and thickened.

Combine and serve

• Return the shrimp to the pan and add the drained pasta, loosening with pasta water if needed.
• Toss everything together and sprinkle with parsley and black pepper.
