Creating Garlic Butter Shrimp Pasta can be simple, yet the final product is nothing short of impressive. Follow these straightforward steps:

1. Boil Pasta: Cook the spaghetti or linguine according to package instructions in a large pot of salted boiling water. Reserve ½ cup of pasta water, then drain the pasta.
2. Sauté Shrimp: In a large skillet, melt 2 tablespoons of butter over medium-high heat. Add the shrimp, season with salt and pepper, and sauté for 2-3 minutes on each side until they turn pink and are opaque. Remove the shrimp and set aside.
3. Prepare Sauce: In the same skillet, add the remaining 2 tablespoons of butter and the minced garlic. Sauté for about 1 minute or until fragrant but not browned.
4. Add Red Pepper Flakes: If using, add red pepper flakes and stir for a few seconds to release their flavor.
5. Combine Ingredients: Return the shrimp to the skillet. Add the drained pasta, reserved pasta water, lemon juice, and Parmesan cheese. Toss everything together until well combined.
6. Adjust Seasoning: Taste and adjust the seasoning with more salt, pepper, or lemon juice if desired.
7. Garnish: Remove from heat and stir in the chopped parsley for freshness.
8. Serve: Plate your Garlic Butter Shrimp Pasta, garnishing with extra Parmesan and lemon wedges. Enjoy immediately.

Following these steps will yield a mouthwatering dish that impresses with its flavor and presentation.
