In a small bowl, whisk together the olive oil, minced garlic, chopped rosemary, chopped thyme, lemon zest, lemon juice, kosher salt, and black pepper.
Place the lamb chops in a large resealable plastic bag or a shallow dish.
Pour the marinade over the lamb chops, ensuring they are well-coated. Seal the bag or cover the dish and refrigerate for at least 1 hour, or up to overnight for the best flavor.
Preheat your grill to medium-high heat (about 400°F 200°C).
Remove the lamb chops from the marinade, letting any excess drip off. Discard the marinade.
Place the lamb chops on the grill and cook for about 3-4 minutes per side for medium-rare, or longer if you prefer them more done. Use a meat thermometer to check the internal temperature (145°F 65°C for medium-rare).
Once the lamb chops are done, remove them from the grill and let them rest for about 5 minutes.
