Flank steak is best cooked to medium rare.

Flank steak, often referred to as a London Broil, is a very lean cut of beef. The cut can become very tough if not prepared and cooked correctly. It is usually cooked to medium rare and rarely cooked past medium. Although very flavorful on its own, a flank steak is best when it's marinaded to tenderize it. A simple marinade can be mixed using common kitchen ingredients. After marinating, the flank steak is grilled to perfection.


Step 1

Mix the marinade in a bowl by combining the oil, ginger, soy sauce, garlic salt, honey, green onions and white vinegar. Stir until all ingredients are thoroughly mixed.

Step 2

Cut lines across the flank steak 1/4-inch deep. Make the scores about 1 inch apart and run them against the grain of the meat.

Step 3

Place the flank steak in a 1-gallon plastic zip-top bag. Pour the marinade into the bag with the steak. Place the bag into the refrigerator and let marinate overnight.

Step 4

Oil the grill racks using a rag. Heat the grill to high temperatures using direct heat.


Step 5

A charcoal grill adds a smoky flavor to the steak.

Remove the steak from the marinade. Sprinkle both sides of the steak with coarse salt and black pepper. Place the steak on the hot grill. Grill each side of the steak for approximately four to six minutes.

Step 6

Remove the flank steak from the grill and cover loosely with aluminum foil. Allow the steak to rest for 10 minutes before slicing.
