Cook the Pasta:
Bring a large pot of salted water to a boil. Add the fettuccine and cook according to the package instructions until al dente. Reserve 1 cup of pasta water, then drain the rest and set the pasta aside.
Sauté the Shrimp:
In a large pan, heat the olive oil over medium heat. Add the minced garlic and sauté for about 30 seconds until fragrant. Then, add the shrimp, cooking for 3-4 minutes or until they turn pink and opaque. Remove the shrimp from the pan and set aside.
Prepare the Alfredo Sauce:
In the same pan, reduce the heat to low and pour in the heavy cream, stirring continuously. Allow it to simmer gently for about 2-3 minutes, then whisk in the Parmesan cheese until fully melted and incorporated.
Combine the Ingredients:
Add the cooked pasta and shrimp back into the pan. Toss everything together well, adding reserved pasta water as needed to reach your desired consistency. Season with salt and pepper to taste.
Garnish and Serve:
Serve the pasta warm, topped with freshly chopped parsley and an extra sprinkle of Parmesan if you like! Enjoy!
