Cook the fettuccine pasta according to package instructions until al dente. Drain and set aside, reserving 1/2 cup of pasta water.
In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant.
Add the shrimp to the skillet and cook for 2-3 minutes on each side until they turn pink and opaque. Remove the shrimp from the skillet and set aside.
In the same skillet, pour in the heavy cream and bring to a simmer. Stir in the Parmesan cheese and Italian seasoning, mixing until the cheese is melted and the sauce is smooth.
Return the shrimp to the skillet and toss to coat in the creamy sauce. If the sauce is too thick, add a little reserved pasta water until desired consistency is reached.
Add the cooked fettuccine to the skillet, tossing everything together until well combined. Season with salt and pepper to taste.
Serve immediately, garnished with fresh parsley.
