Ingredients

  • 1 (1 1/2-pound) flank steak, trimmed

  • ½ cup red wine vinegar

  • 3 tablespoons neutral oil (such as grapeseed), divided

  • 2 tablespoons Worcestershire sauce

  • 2 tablespoons Dijon mustard

  • 2 tablespoons kosher salt

  • 1 tablespoon  light brown sugar

  • 6 garlic cloves, grated 

  • 1 ½ teaspoons black pepper

  • 2 cups mixed woody herb sprigs (such as rosemary and thyme) 

Directions

  1. Place steak in a gallon-size ziplock plastic bag or baking dish. Combine vinegar, 2 tablespoons oil, Worcestershire sauce, mustard, salt, brown sugar, garlic, and pepper in a bowl, and whisk until salt and sugar are dissolved. Pour marinade over steak, distributing marinade evenly. Marinate steak in refrigerator at least 2 hours or up to 24 hours.

  2. Remove steak from refrigerator; let stand at room temperature 15 minutes. Remove steak from bag, and transfer to a paper towel–lined plate; pat dry. Discard marinade. Rub steak with remaining 1 tablespoon oil, and place on a broiler pan or on a wire rack set inside an aluminum foil–lined rimmed baking sheet.

  3. Arrange herbs on a platter; set aside. Preheat oven to high broil with rack positioned 3 to 4 inches from heat source. Place broiler pan in preheated oven, and broil steak 5 minutes. Carefully remove broiler pan from oven; flip steak using tongs, and return to oven. Continue broiling until desired temperature is reached, 2 to 3 minutes for medium-rare (125°F to 135°F). Remove steak from broiler pan, and place on bed of herbs on platter. Tent with foil, and let rest 10 minutes.

  4. Transfer steak to a cutting board, and carve against the grain into 1/4-inch-thick slices. Arrange steak slices on bed of herbs on platter. Serve immediately.
