Ingredients

  • 1 lb flank steak or sirloin, thinly sliced against the grain
  • 1 red bell pepper, sliced
  • 1 green bell pepper, sliced
  • 1 medium yellow onion, sliced
  • 3 garlic cloves, minced
  • 3 tbsp soy sauce
  • 2 tbsp oyster sauce
  • 1 tbsp cornstarch (plus extra for thickening if needed)
  • 1/4 cup water or beef broth
  • 2 tbsp vegetable oil or sesame oil
  • 1/2 tsp black pepper (more to taste)
  • 1 tsp sugar
  • Green onions, chopped (optional, for garnish)

Instructions

  1. In a bowl, marinate sliced beef with 1 tbsp soy sauce, 1/2 tsp sugar, and 1 tbsp cornstarch. Let sit for 15–20 minutes.
  2. Heat 1 tbsp oil in a wok or large skillet over high heat. Stir-fry beef in batches until browned but not fully cooked. Remove and set aside.
  3. In the same pan, add remaining oil and sauté bell peppers and onions for 2–3 minutes until slightly softened but still crisp.
  4. Add garlic and stir for about 30 seconds until fragrant.
  5. Return the beef to the pan.
  6. In a small bowl, mix remaining soy sauce, oyster sauce, water or broth, remaining sugar, and black pepper. Pour over the beef and vegetables.
  7. Stir-fry everything together for a few more minutes until the sauce thickens slightly and the beef is cooked through.
  8. Garnish with chopped green onions before serving, if desired.

Notes

  • Add mushrooms, snap peas, or baby corn for extra veggies.
  • Use red chilies or chili oil for a spicier version.
  • Swap beef for chicken or tofu for variation.
  • Serve over cauliflower rice for a low-carb option.
  • To thicken sauce, mix a little cornstarch with water and stir in at the end.
