Step 1: Pat the shrimp thoroughly dry with paper towels. This is a crucial step for achieving a good sear. Season the dried shrimp generously with salt and black pepper.
Step 2: In a large skillet (cast iron or heavy-bottomed stainless steel works best), heat the olive oil over medium-high heat until shimmering.
Step 3: Add half of the shrimp to the hot pan in a single layer, ensuring not to overcrowd the skillet. Cook for 1-2 minutes per side, until they turn pink and opaque with a slight golden sear. Remove the cooked shrimp to a plate and repeat with the remaining shrimp. Set all cooked shrimp aside.
Step 4: Reduce the heat to medium-low. Add the butter to the same skillet. Once melted, add the minced garlic and red pepper flakes (if using). Sauté for 30 seconds to 1 minute, until fragrant but not browned. Be careful not to burn the garlic.
Step 5: Pour in the chicken broth (or white wine), scraping up any browned bits from the bottom of the pan to deglaze. Let it simmer for about 1 minute until it reduces slightly. Stir in the fresh lemon juice and chopped parsley.
Step 6: Return the cooked shrimp to the skillet. Toss gently to coat the shrimp completely in the delicious garlic butter sauce. Serve your Quick and Easy Garlic Shrimp immediately with your favorite sides.
