01 - Whisk together olive oil, lemon juice, lemon zest, minced garlic, dried oregano, smoked paprika, salt, and black pepper in a medium bowl until thoroughly combined.
02 - Add the peeled and deveined shrimp to the bowl, tossing gently to coat evenly with the marinade. Cover and refrigerate for 15 to 30 minutes, avoiding longer marination to prevent the citrus from over-curing the seafood.
03 - If using wooden skewers, submerge them in water for at least 15 minutes to prevent scorching during grilling. Metal skewers can be used directly.
04 - Heat a grill or grill pan to medium-high temperature, approximately 400°F, ensuring the cooking surface is clean and lightly oiled.
05 - Remove shrimp from the marinade, shaking off excess liquid. Thread each shrimp onto skewers by piercing once near the tail section and once near the head end, leaving slight space between pieces for even heat circulation.
06 - Place skewers on the preheated grill and cook for 2 to 3 minutes per side, turning once, until the shrimp turn opaque throughout and develop light char marks. Do not overcook as shrimp will become rubbery.
07 - Transfer skewers to a serving platter, sprinkle generously with chopped fresh parsley, and arrange lemon wedges alongside for squeezing. Serve immediately while hot.
