Step 1: Prepare the Shrimp
Pat the shrimp completely dry with paper towels—this is crucial for achieving a good sear. Arrange them on a plate in a single layer. In a small bowl, combine the red pepper flakes, smoked paprika, cayenne pepper (if using), salt, and black pepper. Sprinkle this seasoning mixture evenly over both sides of the shrimp, pressing gently so it adheres.

Step 2: Heat Your Skillet
Heat a large skillet over medium-high heat for 2 minutes until very hot. Add the olive oil and swirl to coat the pan. The oil should shimmer but not smoke—if it smokes, reduce heat slightly.

Step 3: Sear the Shrimp (First Side)
Carefully arrange the shrimp in a single layer in the hot skillet, making sure they don’t overlap or touch. Work in batches if necessary—crowding creates steam instead of a sear. Let them cook undisturbed for 2 minutes. The shrimp should develop a beautiful golden-pink color on the bottom with slightly caramelized edges.

Step 4: Flip and Continue Cooking
Using tongs, flip each shrimp to the other side. Cook for an additional 1-2 minutes until the shrimp are just cooked through and opaque. They should curl into a loose “C” shape—avoid overcooking or they’ll become rubbery. Transfer the cooked shrimp to a plate and set aside.

Step 5: Make the Spicy Garlic Sauce
Reduce heat to medium and add the butter to the same skillet. Once melted and foaming, add the minced garlic. Sauté for 30-45 seconds, stirring constantly, until fragrant and just beginning to turn golden. Be careful not to burn the garlic—it turns bitter quickly.

Step 6: Deglaze the Pan
Pour in the white wine (or chicken broth) and lemon juice. Use a wooden spoon to scrape up all those flavorful browned bits stuck to the bottom of the pan. Let the sauce simmer for 1-2 minutes until slightly reduced and thickened.

Step 7: Combine and Finish
Return the cooked shrimp to the skillet along with any accumulated juices from the plate. Toss everything together, coating the shrimp thoroughly in the sauce. Cook for just 30 seconds to reheat the shrimp and let the flavors meld. Remove from heat.

Step 8: Garnish and Serve
Sprinkle the chopped fresh parsley over the shrimp and toss once more. Transfer to a serving platter and serve immediately with lemon wedges on the side for squeezing. The shrimp are best enjoyed piping hot right from the skillet!
