Ingredients

  • 1 lb flank steak or sirloin, thinly sliced against the grain
  • 2 tbsp soy sauce
  • 1 tbsp oyster sauce
  • 1 tbsp cornstarch
  • 1 tbsp rice vinegar
  • 1 tbsp sesame oil
  • 2 tbsp vegetable oil (for cooking)
  • 1 large onion, sliced into wedges
  • 1 green bell pepper, sliced
  • 1 red bell pepper, sliced
  • 2 cloves garlic, minced
  • 1 tsp ground black pepper
  • Optional: sliced green onions or sesame seeds for garnish

Instructions

  1. In a bowl, marinate the sliced beef with soy sauce, oyster sauce, cornstarch, rice vinegar, and sesame oil. Let sit for at least 15 minutes.
  2. Heat 1 tbsp vegetable oil in a large skillet or wok over high heat. Sear the marinated beef in batches until browned but not overcooked. Remove and set aside.
  3. Add the remaining 1 tbsp oil to the skillet. Stir-fry the onions and bell peppers for 2–3 minutes until crisp-tender.
  4. Add garlic and black pepper, stir-frying for 30 seconds until fragrant.
  5. Return beef to the skillet, tossing everything together. Cook for 1–2 minutes until flavors meld and sauce thickens slightly.
  6. Serve hot over steamed rice. Garnish with green onions or sesame seeds if desired.

Notes

  • Add mushrooms or snap peas for extra texture.
  • Stir in chili garlic sauce or fresh chili slices for heat.
  • Swap beef for chicken or tofu as a variation.
  • Add hoisin sauce or brown sugar for a sweeter flavor profile.
  • Best enjoyed fresh, but leftovers store well in the fridge up to 3 days.
