Ingredients

  • 1 1/2 - 2 pounds flank steak
  • 1/4 cup Worcestershire sauce
  • 2 tablespoons reduced sodium soy sauce
  • 2 tablespoons olive oil
  • 1 tablespoon honey or brown sugar
  • 1 tablespoon whole grain mustard
  • 1 tablespoon tomato paste
  • 1 tablespoon capers
  • 2 teaspoons minced garlic 2 cloves
  • 1 teaspoon molasses
  • 1/2 teaspoon coarse salt

Instructions

  • Make the marinade. In a small bowl, combine the marinade ingredients. Whisk until smooth. If you need to heat the honey a bit to make it easier to mix, go for it - 10 or 15 seconds in the microwave should be enough.
    In a large container or zip-top bag, cover the flank steak in marinade and allow it to sit, refrigerated overnight, or for a minimum of 1 hour.
    Before cooking, remove the flank steak from the marinade and pat dry with paper towels. Season with salt & pepper.
  • How to broil flank steak: Preheat your oven to the broil setting, with your broiler pan in oven. When the oven and pan is hot, carefully place the flank steak in the center of the broiler pan.
    Broil for 7 - 9 minutes, or until the steak reaches and internal temperature of 135˚F (for medium-rare). I don't recommend turning the steak when broiling.
  • How to grill flank steak: Heat your grill to medium-high heat (about 450-500˚F). Grill steak for 4 - 5 minutes per side, turning once, or until steak reaches 135˚F for medium-rare.
  • Slice and serve. Let the flank steak rest for 5 - 10 minutes before slicing. Slice thinly against the grain and serve immediately.

Notes

For best results, thinly slice flank steak against the grain with a sharp knife. Serve immediately.
