01 - In a medium mixing bowl, whisk together olive oil, lemon juice, garlic, parsley, smoked paprika, salt, black pepper, and red pepper flakes until fully combined.
02 - Add shrimp to the bowl and toss thoroughly to coat with marinade. Cover and refrigerate for 15 to 30 minutes; avoid marinating for longer to prevent a mushy texture.
03 - Preheat grill or grill pan to medium-high heat.
04 - Thread marinated shrimp onto skewers for grilling. If using wooden skewers, soak them in water for at least 20 minutes before use.
05 - Place skewered shrimp on the hot grill and cook for 2 to 3 minutes per side or until shrimp are pink and opaque.
06 - Transfer grilled shrimp to a serving platter. Garnish with lemon wedges and additional parsley, if desired, and serve immediately.
