Ingredients

Original recipe (1X) yields 4 servings

  • ½ cup reduced-sodium soy sauce

  • ¼ cup rice wine vinegar

  • ¼ cup brown sugar

  • ¼ cup sliced green onions

  • 1 tablespoon minced garlic

  • 1 tablespoon mustard powder

  • 2 pounds flat iron steak

  • 2 tablespoons sesame seeds (Optional)

Directions

  1. Whisk soy sauce, vinegar, brown sugar, green onions, garlic, and mustard powder together in a bowl. Pour into a resealable plastic bag. Add steak, turn to coat in marinade, squeeze out excess air, and seal the bag. Marinate in the refrigerator, 3 to 4 hours.

  2. Remove steak from marinade and discard marinade.

  3. Heat a non-stick skillet over medium-high heat. Cook steak until outside is seared, about 1 minute per side. Continue to cook until desired doneness is reached, about 5 minutes more per side. An instant-read thermometer inserted into the center should read 140 degrees F (60 degrees C).

  4. Remove skillet from heat and allow steak to rest before cutting, 3 to 5 minutes. Sprinkle sesame seeds over steak.

Cook's Note:
