Follow these simple steps to create your Creamy Shrimp Fettuccine Pasta with Homemade Alfredo Sauce:

1. Boil Pasta: In a large pot, bring salted water to a boil. Add the fettuccine and cook according to package instructions until al dente. Drain and set aside, reserving a cup of pasta water.
2. Cook Shrimp: In a large skillet, heat olive oil over medium heat. Add the shrimp and season with salt and black pepper. Cook for 2-3 minutes on each side until they turn pink and are cooked through. Remove them from the skillet and set aside.
3. Sauté Garlic: In the same skillet, add the minced garlic and sauté for about 1 minute until fragrant.
4. Make Alfredo Sauce: Add the butter and heavy cream to the skillet. Stir constantly until the butter melts and the mixture begins to simmer.
5. Add Cheese: Gradually whisk in the Parmesan cheese. Continue stirring until the cheese melts and the sauce becomes creamy. If the sauce is too thick, add a bit of reserved pasta water to reach your desired consistency.
6. Combine Ingredients: Return the shrimp to the skillet and add the cooked fettuccine. Toss everything together to ensure the pasta is well-coated with the sauce.
7. Season: Taste and adjust the seasoning with more salt, black pepper, or red pepper flakes if desired.
8. Garnish: Remove from heat and sprinkle chopped parsley on top before serving.
