Ingredients

  • 2 pounds flank steak
Marinade
  • 3 tablespoons olive oil
  • 3 tablespoons balsamic vinegar
  • 3 tablespoons soy sauce
  • 2 tablespoons Dijon mustard
  • 1 tablespoon Worcestershire sauce 
  • 3 cloves garlic minced
  • 1 tablespoon fresh Rosemary chopped
  • 1 teaspoon black pepper
  • ½ teaspoon red pepper flakes optional

Instructions

    Cup of Yum
  1. Use a sharp knife to lightly score steak in a 1-inch diamond pattern across the steak, about ⅛-inch deep.
  2. Whisk all marinade ingredients in a small bowl or freezer bag. If desired, the marinade can be pulsed a couple of times in a blender. Add steak and marinate at least 4 hours or overnight.
  3. Remove the steak from the fridge at least 30 minutes before cooking. Preheat grill to medium-high heat.
  4. Grill the steak 7-9 minutes, flip over, and grill an additional 5-7 minutes or until it reaches desired doneness. Do not overcook.
  5. Rest 10 minutes before slicing. Slice steak across the grain (cutting across the long fibers).

Notes

  • Scoring the meat allows the marinade to penetrate just a little bit more.
  • Marinate the meat for a minimum of 4 hours so all the flavors can get soaked up into the meat. Do not marinate longer than 24 hours or the meat can become mushy.
  • Cook times are approximate and will vary based on grill temperature and thickness of the meat. A meat thermometer should be used to reach the cook temperatures below. Steaks will rise a couple of degrees while resting so remove from the grill a few degrees early.
  • It’s important to let the meat rest before slicing.
  • IMPORTANT: It is important that flank steak is cut across the grain. You will see long fibers running down the steak, be sure to cut across them.
  • Cook times provided are approximate for a 1" steak and will vary based on steak thickness and temperature.
  • Remove steaks from the heat a few degrees before it reaches the desired temperature as the temperature will continue to rise. The FDA recommends a minimum temperature of 145°F with a 3-minute rest.
