The temperature for broiling in an oven is 260 degrees Celsius or  500 degrees Fahrenheit. Medium heat is about 177 degrees Celsius or  350 degrees Fahrenheit.
Turn off the broiler and set the oven temperature to 325Â°F. Reposition the oven rack to the middle of the oven. Mince the garlic and rosemary leaves. Flip the lamb leg over again and rub the top with the chopped garlic and rosemary.
