Ingredients
  

  • 450 g flank steak, thinly sliced against the grain
  • 1/4 teaspoon baking soda
  • 1 teaspoon cornstarch
  • 1 teaspoon neutral oil (vegetable or canola)
  • 1 teaspoon oyster sauce
  • 1 tablespoon water
  • 1 tablespoon light soy sauce
  • 1 teaspoon dark soy sauce
  • 2 teaspoons ketchup
  • 2 teaspoons oyster sauce
  • 1/4 teaspoon sugar
  • 1/4 teaspoon sesame oil
  • 60 ml water
  • 2 tablespoons cooking oil
  • 280 g small onions, quartered (about 3 small onions)

Equipment

  • Wok
  • Wooden spoon or spatula
  • Measuring spoons and cups
  • Bowls for mixing
  • Large skillet

Method
 

  1. In a medium bowl, mix together flank steak, baking soda, cornstarch, oil, oyster sauce, and water; stir until coated and let marinate for at least 15 minutes.
  2. In a small bowl, whisk together light soy sauce, dark soy sauce, ketchup, oyster sauce, sugar, sesame oil, and water; set aside.
  3. Heat your wok over high heat until smoking, add one tablespoon of oil, and sear the beef in a single layer for 30 seconds; stir-fry until about 75% cooked, then remove and set aside.
  4. Add another tablespoon of oil to the wok, stir-fry the onions until slightly caramelized for about 60 to 90 seconds, and then remove from the wok.
  5. Pour the sauce into the wok, bring to a boil, simmer for 15 seconds, then add the beef and onions back; stir everything for another 30 seconds and serve immediately over rice.

Notes

For a vegetarian option, consider substituting beef with mushrooms or tofu. Be sure to slice the beef against the grain for the best tenderness. Leftovers can be stored in the fridge for up to three days; reheat gently on the stovetop with a splash of water to prevent drying. For added flavor, sprinkle toasted sesame seeds on top before serving. Feel free to use sirloin instead of flank steak if preferred; adjust sauce ingredients as needed for personal taste.
