01 - In a medium mixing bowl, thoroughly whisk together the olive oil, fresh lemon juice, lemon zest, minced garlic, dried oregano, smoked paprika, crushed red pepper flakes (if using), kosher salt, and freshly ground black pepper until well combined.
02 - Add the peeled and deveined shrimp to the prepared marinade. Gently toss to ensure each shrimp is evenly coated. Cover the bowl and refrigerate for 15 to 30 minutes; do not exceed 1 hour to prevent the shrimp from becoming mushy.
03 - Preheat your grill or grill pan to medium-high heat. If using wooden skewers, submerge them in water for at least 20 minutes prior to use to prevent burning.
04 - Carefully thread the marinated shrimp onto the prepared skewers, arranging approximately 4 to 5 shrimp per skewer.
05 - Place the shrimp skewers on the preheated grill. Cook for 2 to 3 minutes per side, or until the shrimp turn opaque, pink, and exhibit slight charring.
06 - Remove the cooked skewers from the grill. Sprinkle generously with fresh chopped parsley and serve immediately with lemon wedges for an extra burst of citrus flavor.
