In a small bowl, mix together minced garlic, chopped rosemary, lemon zest and juice, olive oil, salt, and pepper until well combined.
Place the lamb chops in a large dish and pour the marinade over them, ensuring all chops are thoroughly coated. Cover the dish and refrigerate for a minimum of 2 hours.
Preheat your grill to medium-high heat.
Take the lamb chops out of the marinade, shaking off any excess, and grill them for approximately 4-5 minutes per side for medium-rare or until they reach your preferred level of doneness.
Allow the lamb chops to rest for a few minutes before serving to allow the juices to redistribute.
Serve the grilled lamb chops with a side of grilled vegetables or a fresh salad for a delightful meal.
