In a large skillet, over medium heat, melt the unsalted butter until bubbly and fragrant. As soon as the butter is melted, add the minced garlic, sautéing for about 1-2 minutes until it becomes fragrant without turning brown.
Add the peeled and deveined shrimp to the skillet. Season them with salt and freshly ground black pepper. Cook the shrimp for approximately 2-3 minutes on each side, or until they turn a vibrant pink and opaque, indicating they are fully cooked.
Once the shrimp are cooked, reduce the heat to low. Carefully pour in the heavy cream, stirring well to combine all the flavors in the skillet.
Next, gradually add the finely grated Parmesan cheese into the skillet, stirring continuously. Keep stirring until the cheese is fully melted and the sauce thickens, which should take about 2-3 minutes.
Stir in the lemon zest to enhance the sauce with a refreshing brightness. Taste and adjust the seasoning with additional salt or pepper as necessary.
Serve the creamy garlic shrimp generously over the cooked pasta, making sure to drizzle some luscious sauce over the top for added flavor.
Finish by garnishing the dish with a sprinkle of finely chopped fresh parsley to add a pop of color and a fresh herbal note.
Notes
For an elegant touch, serve the dish in a shallow bowl with extra Parmesan and lemon slices.
