Ingredients:

  • 1 lb sirloin steak, thinly sliced against the grain
  • 4 tbsp soy sauce
  • 1 tbsp Shaoxing wine
  • 2 tsp cornstarch
  • 1/2 tsp baking soda
  • 2 tbsp oyster sauce
  • 1 tbsp brown sugar
  • 1 tsp toasted sesame oil
  • 2 tbsp water
  • 2 tbsp vegetable oil
  • 3 large green bell peppers, sliced into strips
  • 1 medium yellow onion, sliced
  • 3 cloves garlic, minced
  • 1 tbsp fresh ginger, grated

Instructions:

  1. Slice the sirloin into thin strips against the grain to ensure tenderness.
  2. In a bowl, combine beef with 1 tbsp soy sauce, Shaoxing wine, 1 tsp cornstarch, and baking soda. Toss until coated and let rest for 15–20 minutes.
  3. In a separate bowl, whisk together 3 tbsp soy sauce, oyster sauce, brown sugar, sesame oil, 1 tsp cornstarch, and water or beef broth.
  4. Heat 1 tbsp vegetable oil in a wok or cast-iron skillet over medium-high heat until shimmering.
  5. Add beef in a single layer, sear undisturbed for 1 minute, then stir-fry for 1–2 minutes until lightly browned. Remove beef to a plate.
  6. Add remaining 1 tbsp oil to the pan. Stir-fry green peppers and onions for 2–3 minutes until crisp-tender.
  7. Add minced garlic and grated ginger, cooking for 30 seconds until fragrant.
  8. Return the beef to the pan and pour in the stir fry sauce. Toss rapidly for 1–2 minutes until the sauce thickens and glazes the ingredients.
