Preheat the broiler to high. Set the rack at the top setting.
On a flat work surface, smash the garlic cloves with the side of a knife until mashed. Sprinkle the salt, rosemary and ground coriander on top of the smashed garlic. (Do not add the olive oil until done cooking.) Chop the ingredients together until the garlic and rosemary are finely minced.
Place the lamb chops on a sheet pan. Spread an even amount of the rub onto both sides of each lamb chop. Broil each side 3-4 minutes for medium-rare.
Remove the chops to a plate and drizzle with the olive oil.
