Bring a large pot of salted water to a boil and cook fettuccine according to package directions until al dente.
Pat shrimp dry and season with a pinch of salt and pepper.
Heat olive oil in a large skillet over medium-high heat. Add shrimp and cook for 2 minutes per side until pink and opaque. Remove shrimp and set aside.
In the same skillet, melt butter over medium heat. Add minced garlic and sauté for 1 minute until fragrant.
Whisk in heavy cream and bring to a gentle simmer. Reduce heat to low and simmer for 3-5 minutes until slightly thickened.
Gradually whisk in Parmesan cheese until melted and smooth.
Add the cooked pasta and shrimp to the skillet. Toss thoroughly to coat with the sauce.
Season with salt and pepper to taste and garnish with fresh parsley before serving.
