Start by seasoning the lamb chops. Sprinkle salt, ground black pepper, rosemary leaves and olive oil.
Coat the lamb chops with the seasoning very well. And set aside for 10 minutes.
Place the lamb chops in a grilling basket, and transfer to the barbecue grill.
Cook on each side for about 7 minutes for well-done. Keep flipping the grilling basket to make sure that the meat is cooked evenly on both sides.
Using your Thermapen kitchen thermometer, check the temperature of the meat. For well-done, the temperature should be 80-85°C. For medium-well, 70-70°C. And for rare, 63-69°C.
