Ingredients
  

  • 2 to 2½- pound flank Steak

Marinade

  • 4 garlic cloves minced
  • 2 green onions white and light green parts only, thinly sliced
  • 1 tablespoon white balsamic vinegar
  • tablespoons fresh rosemary chopped
  • ½ cup olive oil
  • ½ teaspoon Kosher salt
  • ½ freshly ground pepper

Herb Sauce

  • 2 green onions white and light green parts only, finely chopped
  • 3 garlic cloves finely chopped
  • ½ tablespoon crushed hot chili pepper paste
  • ¼ cup white vinegar
  • ¼ cup balsamic vinegar
  • 1 teaspoon kosher salt
  • 5 tablespoons finely chopped flat-leaf parsley
  • 3 tablespoons finely chopped basil
  • ¾ cup extra-virgin olive oil

Instructions
 

Marinade

  • In a small bowl, combine all of the marinade ingredients. Set aside.
  • Crosshatch the top of the steak to help with the absorption of the marinade and give additional surfaces to char when grilling. This is done by slicing diagonally across the surface of the steak, in a diamond pattern. Make the slices about ¼ inch deep, and space them roughly ¾ inch apart.
  • Add the meat to a quarter sheet pan (or use a resealable bag) and pour in all the marinade; turn the meat to coat. Cover the pan and refrigerate for 2 to 4 hours.

Herb Sauce

  • Combine onions, garlic, hot chili, vinegar, and salt in a medium bowl. Let sit 10 minutes.
  • Stir in the parsley, basil, and olive oil. Set aside.

Grill the Steak

  • Remove the steak from the fridge 30 minutes prior to grilling. Preheat the grill on high. Remove the steak from the marinade, and let the excess marinade drip off.
  • Season the steak with a sprinkle of kosher salt.
  • Grill the steak over high heat, turning 90° once, then flipping, then turning again, until nicely charred and an instant-read thermometer inserted in the thickest part registers 125-130°F, total cooking time 6 to 10 minutes (this time will vary based on thickness of the steak, temperature of the grill, outside temperature and how much the lid of the grill is open or closed).
  • Transfer the steak to a carving board and let rest for 5-10 minutes. Thinly slice the meat against the grain and serve with herb sauce.
