Ingredients

Scale
  • 1 pound flank steak, thinly sliced
  • 1 tablespoon cornstarch
  • 1 tablespoon soy sauce
  • 1 tablespoon vegetable oil
  • 1/2 cup soy sauce
  • 1/2 cup beef broth
  • 1/4 cup brown sugar
  • 1 tablespoon oyster sauce
  • 1 teaspoon sesame oil
  • 1 teaspoon minced garlic
  • 1 teaspoon minced ginger
  • 1/4 teaspoon red pepper flakes (optional)
  • 2 green onions, sliced
  • Cooked white rice, for serving

Instructions

  1. In a bowl, toss the thinly sliced steak with 1 tablespoon of cornstarch and 1 tablespoon of soy sauce.
  2. Heat the vegetable oil in a large skillet or wok over medium-high heat.
  3. Add the steak to the skillet and cook until browned, about 2-3 minutes. Remove the steak from the skillet and set aside.
  4. In the same skillet, combine 1/2 cup soy sauce, beef broth, brown sugar, oyster sauce, sesame oil, minced garlic, minced ginger, and red pepper flakes (if using).
  5. Bring the sauce to a simmer, stirring until the brown sugar dissolves.
  6. Return the steak to the skillet and toss to coat with the sauce. Cook for another 1-2 minutes until the sauce thickens slightly and the steak is heated through.
  7. Stir in the sliced green onions.
  8. Serve immediately over cooked white rice.

Notes

  • For best results, slice the steak against the grain.
  • You can adjust the sweetness by adding more or less brown sugar.
  • Add your favorite vegetables like broccoli or bell peppers for extra flavor and nutrition.
