Ingredients

  • 400g beef, thinly sliced
  • 150ml water
  • 1 tsp baking soda
  • Marinade:
    • 2 tbsp oyster sauce
    • 1 tbsp sweet soy sauce
    • 1 tsp Worcestershire sauce
  • Stir-Fry:
    • 2 cloves garlic, minced
    • 1 onion, sliced
    • 1 large chili, sliced
    • 2 bell peppers, sliced
  • Sauce:
    • 200ml water
    • 2 tbsp soy sauce
    • 2 tbsp sweet soy sauce
    • 1 tbsp oyster sauce
    • 1 tbsp Worcestershire sauce
    • 1/2 tbsp sugar
    • 1 tbsp freshly cracked black pepper
  • Thickener:
    • 1 tbsp cornstarch mixed with 2 tbsp water (slurry)

Instructions

  1. Combine beef, 150ml water, and baking soda. Let marinate for 15 minutes to 2 hours. Rinse and drain thoroughly.
  2. Marinate drained beef with oyster sauce, sweet soy sauce, and Worcestershire sauce for 10–30 minutes.
  3. Heat oil in a pan or wok over medium-high heat. Stir-fry the marinated beef until 75% cooked. Remove and set aside.
  4. In the same pan, sauté garlic and onion until fragrant. Add chili and bell peppers; cook for 2–3 minutes.
  5. Add 200ml water, soy sauce, sweet soy sauce, oyster sauce, Worcestershire sauce, sugar, and black pepper. Stir and bring to a simmer.
  6. Return beef to the pan and coat evenly with the sauce.
  7. Stir in cornstarch slurry and cook until sauce thickens and clings to the beef and vegetables.
  8. Adjust seasoning to taste and serve hot with steamed rice.

Notes

  • Use baking soda for a more tender beef texture, especially with tougher cuts.
  • Freshly cracked black pepper adds the best flavor—adjust to taste for heat level.
  • To avoid overcooking the beef, cook it quickly in batches if needed.
  • Leftovers are great for lunch the next day—store with rice in meal prep containers.
