Broil varies on different ovens. Some are 500 to 550 degrees Fahrenheit, and others are 400 to 450 degrees Fahrenheit. For broiling crab cakes, set the oven to broil and check it at 1-5 minutes, until lightly browned. If you do not have a broil setting, turn the oven up to cook at 500 for 1-5 minutes, until crispy.
