Ingredients

  • 450 g sirloin steak, thinly sliced against the grain
  • 1 red bell pepper, sliced into strips
  • 1 green bell pepper, sliced into strips
  • 1 yellow onion, sliced
  • 3 cloves garlic, minced
  • 3 tbsp vegetable oil, divided
  • 3 tbsp low-sodium soy sauce
  • 1 tbsp Worcestershire sauce
  • 2 tbsp oyster sauce
  • ⅓ cup beef broth
  • 1½ tbsp cornstarch
  • 1 tsp freshly cracked black pepper
  • 1 tsp sesame oil
  • 4 cups cooked white rice, for serving

Directions

  1. 1Toss sliced steak with 1 tbsp soy sauce and ½ tbsp cornstarch; set aside to marinate 10 minutes.
  2. 2Whisk remaining soy sauce, Worcestershire, oyster sauce, beef broth, remaining cornstarch, black pepper, and sesame oil together to form the sauce.
  3. 3Heat 2 tbsp oil in a wok over high heat until smoking; sear beef in a single layer 90 seconds per side until browned; transfer to a plate.
  4. 4Add remaining oil to wok; stir-fry onion 2 minutes until softened at the edges.
  5. 5Add garlic and bell peppers; stir-fry 2 minutes until peppers are just tender-crisp.
  6. 6Return beef to the wok, pour in sauce, and toss over high heat 1–2 minutes until everything is glossy and sauce has thickened.
  7. 7Serve immediately over steamed white rice.

💡 Sirloin is ideal, but top round or flank steak work well and are more economical. Don't skip the black pepper — it's the soul of this dish.
