01 - In a medium bowl, whisk together the olive oil, lemon juice, minced garlic, smoked paprika, dried oregano, salt, black pepper, red pepper flakes, and chopped parsley until well combined.
02 - Pat the shrimp dry with paper towels. Add them to the marinade and toss thoroughly to coat evenly. Cover the bowl and refrigerate for 20 minutes to allow the flavors to penetrate.
03 - Preheat an outdoor grill or grill pan to medium-high heat. Lightly oil the grates to prevent the shrimp from sticking.
04 - Remove the shrimp from the marinade and thread them onto skewers. If using wooden skewers, soak them in water for at least 20 minutes beforehand to prevent burning.
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 lightly charred. Avoid overcooking to keep them tender.
06 - Remove the shrimp from the grill and serve immediately. Garnish with additional fresh parsley and lemon wedges if desired.
