What Temperature Do You Cook Flank Steak At?
Flank steak should be cooked on high heat for a short time, such as 3-4 minutes per side on a hot grill or under a broiler. The internal temperature of the steak should reach 130-135°F (54-57°C) for medium-rare and 140°F (60°C) for medium. Let the steak rest for a few minutes before slicing against the grain.
