Ingredients
    For the Stir Fry Sauce
  • 3 tbsp soy sauce (use low-sodium if preferred)
  • 1 tbsp oyster sauce (halal-certified)
  • 1 tbsp sesame oil
  • 1 tbsp rice vinegar or white vinegar
  • 1 tbsp brown sugar (or honey)
  • 2 cloves garlic (minced)
  • 1 tsp fresh ginger (grated)
  • 1 tsp cornstarch (for thickening)
  • 3 tbsp water
    • For the Beef Stir Fry
  • 400 g beef sirloin or flank steak (thinly sliced against the grain)
  • 1 tbsp cornstarch
  • 1 tbsp soy sauce
  • 1 tbsp vegetable oil (for marinating beef)
  • 2 tbsp vegetable oil (for stir frying)
  • 1 red bell pepper (thinly sliced)
  • 1 green bell pepper (thinly sliced)
  • 1 small onion (sliced)
  • 1 tbsp sesame seeds (toasted)
  • 2 stalks green onions (sliced, for garnish)
    • Optional Sides
  • Cooked jasmine rice or noodles (for serving)
Instructions
    Prepare the Beef
  1. 1
    Marinate the thinly sliced beef in soy sauce, cornstarch, and a tablespoon of oil. Mix well to coat evenly. Let it rest for about 10–15 minutes. This helps tenderize the beef and lock in flavor.
    2. Make the Stir Fry Sauce
  2. 2
    In a small bowl, whisk together soy sauce, oyster sauce, sesame oil, vinegar, brown sugar, garlic, ginger, cornstarch, and water. Stir until the sugar and cornstarch are fully dissolved. Set aside.
    3. Sear the Beef
  3. 3
    Heat a wok or large skillet over medium-high heat (around 200°C). Add a tablespoon of oil and swirl to coat the surface. Add the marinated beef in batches to avoid overcrowding. Sear for 2–3 minutes until browned but not overcooked. Remove and set aside on a plate.
    4. Stir Fry the Vegetables
  4. 4
    In the same wok, add another tablespoon of oil. Toss in sliced onions and bell peppers. Stir fry for about 2–3 minutes until slightly tender but still crisp. The vegetables should retain their color and crunch.
    5. Combine Everything
  5. 5
    Return the cooked beef to the wok. Pour the stir fry sauce over the mixture and toss continuously for 2–3 minutes until the sauce thickens slightly and coats the beef and vegetables evenly.
    6. Add Sesame Seeds & Garnish
  6. 6
    Sprinkle toasted sesame seeds and sliced green onions over the stir fry. Toss gently once more for even distribution.
    7. Serve
  7. 7
    Serve hot with steamed jasmine rice or noodles. For a finishing touch, drizzle a small amount of extra sesame oil before serving.
Note

Tenderizing Tip: Always slice beef against the grain for maximum tenderness.

Vegetable Options: You can also add snap peas, carrots, or baby corn for variation.

Sauce Consistency: If the sauce thickens too much, add 1–2 tbsp of water to loosen it.

Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in a skillet over medium heat before serving.

Meal Prep Friendly: You can prepare the sauce and slice the beef a day ahead to save time.
