01 - In a medium bowl, whisk together olive oil, lemon juice, lemon zest, minced garlic, sea salt, black pepper, and crushed red pepper flakes if using.
02 - Add the shrimp to the marinade, toss to coat evenly, and let rest for 10 to 15 minutes to absorb flavors.
03 - If using wooden skewers, submerge them in water for at least 10 minutes to prevent burning during grilling.
04 - Heat a grill or grill pan over medium-high heat until hot and ready for cooking.
05 - Skewer about 4 to 5 marinated shrimp per stick, ensuring they are evenly spaced.
06 - Place skewers on the grill and cook for 2 to 3 minutes per side, until shrimp are opaque and lightly charred.
07 - Remove shrimp from grill, immediately sprinkle with fresh parsley, and serve hot with lemon wedges on the side.
