Making Garlic Butter Shrimp Pasta is a straightforward process that will have you impressing guests in no time. Follow these steps to achieve a delectable result:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add the pasta and cook according to package instructions until al dente. Drain and set aside, reserving a cup of pasta water.
2. Sauté the Shrimp: In a large skillet, melt 2 tablespoons of butter over medium heat. Add the shrimp in a single layer and cook for 2-3 minutes on each side until they turn pink and opaque. Remove the shrimp from the skillet and set them aside.
3. Prepare the Sauce: In the same skillet, add the remaining 2 tablespoons of butter. Once melted, add minced garlic and red pepper flakes. Sauté for about 1-2 minutes until the garlic is fragrant, being careful not to burn it.
4. Combine Ingredients: Return the cooked shrimp to the skillet and toss to coat with the garlic butter. Squeeze fresh lemon juice over the mixture.
5. Mix with Pasta: Add the cooked pasta to the skillet, tossing everything to combine. If the mixture seems dry, add some reserved pasta water, a little at a time, until desired consistency is achieved. Season with salt and black pepper, to taste.
6. Garnish and Serve: Remove from heat and sprinkle with chopped fresh parsley. Serve immediately with grated Parmesan cheese, if desired.

By following these straightforward instructions, you’ll create a dish that showcases the rich flavors of garlic and the sweetness of shrimp, all tied together with a luscious butter sauce.
