01 - Combine olive oil, minced garlic, rosemary, thyme, lemon zest, sea salt, and black pepper in a bowl. Coat the lamb cutlets thoroughly with the marinade. Cover and refrigerate for at least 30 minutes, up to 4 hours for enhanced flavor.
02 - In a separate small bowl, mix Greek yogurt, chopped mint, parsley, lemon juice, ground cumin, salt, and pepper. Cover and chill until serving.
03 - Heat a grill or grill pan over medium-high heat. Remove lamb cutlets from the marinade, letting excess drip off.
04 - Grill the cutlets for 3 to 4 minutes per side for medium-rare, or adjust timing to desired doneness. Remove from grill and let rest for 2 minutes before serving.
05 - Serve the grilled lamb cutlets accompanied by the mint yogurt sauce, lemon wedges, and fresh mint sprigs.
