  • 3/4 cup low sodium soy sauce
  • 1/4 cup olive oil
  • 1/4 cup packed brown sugar
  • 1 tablespoon cider vinegar
  • 1 tablespoon Worcestershire sauce
  • 2 teaspoons Dijon mustard
  • 1/2 teaspoon ground pepper
  • 2 teaspoons garlic chopped
  • 1 1/2 pounds flank steak


  • Combine the soy sauce, olive oil, brown sugar, cider vinegar, Worcestershire sauce, mustard and pepper in a resealable bag; seal and shake to combine. 
  • Reserve 2 tablespoons of the marinade for later use. Stir the garlic into the bag of marinade.
  • Add the steak and marinate for 2-24 hours.
  • Heat an outdoor grill or stove top grill pan to medium-high. Place the steak on the grill and cook for 5-6 minutes per side, depending on the thickness of your meat and the desired level of doneness.
  • Remove the meat from grill and cover with foil. Let stand for 5-10 minutes and then slice thinly against the grain with a very sharp knife. Drizzle with reserved marinade, then serve.
