What is Flank Steak?
Flank Steak is a lean cut of beef that is very flavorful. However, because it is so lean, it can get dry and tough very easily. For the best flank steak, it is best to cook it quickly and sear the outside. Flank steak is not a steak you want to cook above medium – or 145 degrees F.

How to Grill Flank Steak
Flank steak is best when it is cooked quickly over high heat. You want to sear the outside to a nice mahogany brown but not overcook the inside. Flank steak is best when it is not overcooked. Cooking any higher than medium (145 degrees F) will give you dry, tough steak. For tender flank steak, medium rare (135 degrees F) to medium is best.
Grill steak over high heat, flip every 45 seconds for 7-8 minutes or until it reaches desired internal temperature.
