  • 1/3 cup soy sauce
  • ½ cup olive oil
  • 2 tablespoons honey
  • 2 tablespoons Worchestershire sauce
  • 1 tablespoon lime juice or red wine vinegar / balsamic vinegar
  • ½ small onion small chunks
  • 3 cloves garlic minced (1 tablespoon minced garlic)
  • 2 tablespoons green onions minced
  • 1 tablespoon Italian seasoning or fresh thyme and rosemary
  • ½ teaspoon black pepper
  • ½ teaspoon salt
  • 2 pounds flank steak (907g)


  • Add all ingredients except the steak to a mixing bowl. Whisk together until fully combined.
  • Pierce the flank steak with a fork all over, and then place in the bowl*.
  • Turn the steak several times to coat thoroughly.
  • Cover the bowl with plastic wrap and place in the fridge for 2-24 hours.
  • Remove from the fridge 30 minutes before grilling. Take the steak out of the marinade and remove excess moisture with paper towels. Discard the marinade**.
  • Preheat grill for medium-high heat, about 400°F (204°C).
  • Spray the grill grates with cooking oil spray.
  • When hot, place flank steak on the grill.
  • Grill the first side for 1 minute to sear. Then flip the steak and grill 1 minute on the other side.
  • Continue cooking for 2-3 minutes per PER SIDE to desired doneness***, flipping every minute for even cooking.
  • Remove to a cutting board and let the steak rest covered with aluminum foil for 5 minutes (this is so the juices retreat into the meat).
  • Slice thinly against the grain to serve.


  • *You can also marinate flank steak in a large zip-top bag instead of a bowl.
  • **Leftover marinade should be discarded since it has bacteria from the raw meat.
  • ***Flank steak is best cooked medium-rare to medium; measure with an instant-read thermometer: remove from heat at 125°F (52°C) for rare, 130°F (54°C) for medium-rare and 140°F (63°C) for medium. The temperature will rise several more degrees while resting.
  • Avoid piercing/cutting into the steak during cooking, as juices will escape making the meat drier.
