01 - In a medium bowl, whisk together the olive oil, lemon juice, minced garlic, chopped parsley, smoked paprika, salt, black pepper, and red pepper flakes until well combined.
02 - Add the peeled and deveined shrimp to the marinade, tossing to coat evenly. Cover the bowl and refrigerate for 15 to 30 minutes. Do not exceed 30 minutes, as the acid will begin to break down the texture and cause mushiness.
03 - Preheat an outdoor grill or grill pan to medium-high heat, approximately 400°F. If using wooden skewers, soak them in water for at least 20 minutes beforehand to prevent burning.
04 - Remove the shrimp from the marinade, allowing excess to drip off. Thread the shrimp onto skewers, spacing them evenly for uniform cooking.
05 - Place the skewers on the hot grill and cook for 2 to 3 minutes per side, turning once, until the shrimp are pink, opaque, and slightly charred at the edges.
06 - Transfer the grilled shrimp to a serving platter. Garnish with fresh lemon wedges and additional chopped parsley. Serve immediately while hot.
