Creating Creamy Garlic Butter Shrimp Alfredo is simple when you follow these steps:

1. Cook the Pasta: Boil a large pot of salted water. Add fettuccine and cook according to package instructions until al dente. Reserve ½ cup of pasta water, then drain and set aside.

1. Sauté the Shrimp: In a large skillet, melt 2 tablespoons of butter over medium heat. Add the shrimp and cook for 2-3 minutes on each side or until pink and cooked through. Season with salt and pepper. Remove shrimp and set aside.

1. Make the Sauce: In the same skillet, melt the remaining 2 tablespoons of butter. Add garlic and sauté for about 1 minute, until fragrant.

1. Add Cream: Slowly pour in the heavy cream, stirring to combine. Allow the sauce to simmer for 2-3 minutes, thickening slightly.

1. Incorporate Cheese: Stir in the grated Parmesan cheese, mixing until melted and smooth. If the sauce is too thick, gradually add reserved pasta water.

1. Combine Ingredients: Add cooked fettuccine and shrimp back to the skillet. Toss everything together until well coated in the creamy sauce.

1. Season: Taste and adjust seasoning with salt, pepper, and red pepper flakes if you prefer a bit of heat.

1. Serve Immediately: Garnish with fresh parsley before plating.

These straightforward steps will guide you to a plate full of pleasure and satisfaction!
