Mince 3 tbsp. rosemary and 2 tbsp. of garlic. Place 6 lamb rib chops in a large, sealable bag with minced rosemary, 2 oz. olive oil, minced garlic, 1 tsp. salt and ½ tsp. pepper. Massage the bag slightly to make sure the chops are equally covered in the marinade. Refrigerate for at least 1 hour.
Once lamb has marinated, use a paper towel to blot lamb chops and brush off some of the garlic and rosemary. You don’t want too much of it still stuck to the meat or it may char as it sears.
Add 1 tbsp. olive oil to the pan, and turn the heat to MEDIUM-HIGH. Allow the pan to get very hot, about 1-2 minutes. Place lamb chops in the oil, at least an inch apart, and allow them to sear without moving or flipping for 3 minutes. Then, carefully flip them to the other side.
Use a meat thermometer to check for doneness. If you want your chops to be RARE, the temperature should be 120 F. If you want them to be MEDIUM RARE, the temperature should be 125 F. If you want them MEDIUM, the temperature should be 135 F. And for WELL DONE, 145 F. If after the chops have been in the pan for 6 minutes, and you want them to be more fully cooked, turn the heat to MEDIUM-LOW, flip them, and allow them to cook for just 1 minute on each side, flipping until they reach your desired temperature. Serve right after removing from pan.
