To create the perfect Shrimp Alfredo, follow these simple steps:

1. Cook the Fettuccine: Bring a large pot of salted water to a boil. Add the fettuccine and cook according to package instructions until al dente. Reserve 1 cup of pasta water, then drain the rest.

2. Sauté the Shrimp: In a large skillet over medium heat, add the olive oil. Once hot, add the shrimp. Season with salt and black pepper. Cook for about 2-3 minutes on each side, or until they turn pink and opaque. Remove from skillet and set aside.

3. Make the Sauce: In the same skillet, add the butter and let it melt. Add the minced garlic and sauté for about 1 minute, or until fragrant.

4. Add Cream: Pour in the heavy cream and bring to a gentle simmer. Cook for about 3-4 minutes, allowing the sauce to thicken slightly.

5. Incorporate Cheese: Gradually stir in the grated Parmesan cheese until melted and smooth. If the sauce is too thick, add some reserved pasta water to reach your desired consistency.

6. Combine Pasta and Shrimp: Add the drained fettuccine and sautéed shrimp to the sauce. Toss everything together until well coated.

7. Season to Taste: Adjust salt and pepper as needed, and mix until all ingredients are combined.

8. Serve with Garnish: Remove from heat and transfer the Shrimp Alfredo to serving plates. Garnish with chopped parsley and serve with lemon wedges if desired.
