Step 1

Rinse and dry shrimp.

Step 2

Whisk olive oil, garlic, lemon juice, pepper, and parsley together in a bowl and pour into a large resealable plastic bag. Add shrimp, coat with the marinade, squeeze out excess air, and seal the bag. Marinate in the refrigerator for 2 hours.

Step 3

Preheat an outdoor grill for medium heat and lightly oil the grate. Lightly coat metal skewers with cooking spray.

Step 4

Remove shrimp from the marinade and shake off excess. Discard the remaining marinade. Place about 5 shrimp on each skewer.

Step 5

Cook on the preheated grill until shrimp are bright pink on the outside and the meat is opaque, about 5 minutes; do not overcook.
