Prepare the Shrimp: Start by rinsing the shrimp under cold water and patting them dry with paper towels. This helps to ensure the shrimp sear nicely.

Melt the Butter: In a large skillet over medium heat, add the unsalted butter. Allow it to melt completely and become bubbly, but be careful not to let it brown.

Sauté Garlic: Once the butter is melted, add the minced garlic to the skillet. Sauté for about 1 minute, or until the garlic is fragrant and lightly golden. Stir frequently to prevent burning.

Add Shrimp: Increase the heat to medium-high. Add the prepared shrimp to the skillet in a single layer. Season with smoked paprika, chili flakes, salt, and black pepper.

Cook the Shrimp: Cook the shrimp for about 2-3 minutes on one side until they start to turn pink. Flip the shrimp and cook for an additional 2-3 minutes on the other side, or until they are fully cooked and opaque.

Finish with Lemon and Parsley: Once the shrimp are cooked through, remove the skillet from heat. Squeeze the juice of one lemon over the shrimp and gently toss in the chopped parsley.

Serve: Plate the garlic butter shrimp and garnish with additional parsley and lemon wedges if desired. Serve immediately with crusty bread, rice, or pasta to soak up the delicious sauce.
