01 - Whisk together olive oil, lemon juice, lemon zest, minced garlic, salt, and pepper in a large bowl until well combined.
02 - Add shrimp to the bowl and toss to coat evenly. Cover and refrigerate for 10-15 minutes to absorb flavors.
03 - If using wooden skewers, soak in water for at least 15 minutes to prevent burning during grilling.
04 - Thread marinated shrimp onto skewers, piercing through both head and tail ends for stability, about 5-6 shrimp per skewer.
05 - Heat grill or grill pan to medium-high temperature.
06 - Cook shrimp skewers for 2-3 minutes per side until pink and opaque throughout.
07 - Remove from grill, sprinkle immediately with chopped parsley, and serve hot with fresh lemon wedges.
