While some ovens let you set a broiler temperature, others just have the option of LOW vs. HIGH, which is typically between 400ºF-450ºF for low, and 500ºF -550ºF for high. For broiled salmon, position the rack about 6 inches from the top heat source. The best broiled salmon temperature is 500ºF-550ºF if you have the option to set it. If not, simply select "broil" on HIGH.
