Add the lamb chops and turn to coat well. Cover and refrigerate for at least 30 minutes, or up to 8 hours for deeper flavor.
03 -
Remove the lamb from the refrigerator 20-30 minutes before grilling. Pat off excess wet marinade with paper towels so the chops brown cleanly.
04 -
Heat a clean grill to medium-high, about 400°F (200°C). Oil the grates lightly right before adding the lamb.
05 -
Grill the chops for 3-5 minutes per side, depending on thickness, until nicely charred and cooked to your preferred doneness. For many medium-rare chops, aim for about 130°F before resting. For USDA guidance, cook whole cuts of lamb to 145°F with a rest.

Transfer the chops to a platter and rest for 5 minutes. Sprinkle with parsley and serve with lemon wedges.
