Begin by bringing a large pot of water seasoned with salt to a rolling boil. Add the linguine pasta and cook according to the package instructions until it reaches an al dente texture, typically about 8-10 minutes. Once cooked, thoroughly drain the pasta, but be sure to reserve approximately 1/2 cup of the starchy pasta water for later use.
In a large skillet, set over medium heat, add the unsalted butter. Allow it to melt completely, then introduce the minced garlic. Sauté the garlic for about 1 minute, stirring frequently, until it becomes fragrant—watch closely to prevent burning it.
Carefully add the cleaned shrimp to the skillet. Season generously with salt, ground black pepper, and the red pepper flakes for a hint of heat. Cook the shrimp for approximately 2-3 minutes on each side until they transform into a beautiful pink color and are opaque throughout.
To the skillet, pour in the fresh lemon juice and add the lemon zest. Then, carefully add the drained linguine, tossing all the ingredients together. Gradually incorporate the reserved pasta water, a little at a time, until you achieve your desired sauce consistency—this will ensure the dish remains luscious and moist.
Remove the skillet from the heat. Gently fold in the chopped parsley and taste for seasoning, adjusting with additional salt and pepper according to your preference.
To serve, plate the flavorful linguine and shrimp enticingly in shallow bowls. Generously sprinkle grated Parmesan cheese on top, and for a finishing touch, add a little extra parsley for vibrant color and freshness if desired.
Notes
Reserve some pasta water to adjust the sauce consistency.
