Ingredients

Scale
  • 1 lb flank steak (or sirloin/ribeye), thinly sliced against the grain

  • 2 tbsp soy sauce (divided)

  • 2 tsp cornstarch (divided)

  • 1 tbsp oyster sauce

  • 1/2 cup beef broth

  • 1 tbsp vegetable oil (plus more if needed)

  • 3 cloves garlic, minced

  • 1 tbsp fresh ginger, minced

  • 1 large onion, sliced into wedges

  • 1 red bell pepper, sliced into strips

  • 1 green bell pepper, sliced into strips

  • 1 tsp sesame oil

  • Optional: chopped green onions for garnish


Instructions

  1. Prep the Beef: Place sliced steak in a bowl and toss with 1 tbsp soy sauce and 1 tsp cornstarch. Set aside for 10 minutes.

  2. Make the Sauce: In a small bowl, whisk together remaining soy sauce, oyster sauce, beef broth, and remaining cornstarch until smooth.

  3. Sear the Beef: Heat oil in a wok or skillet over high heat. Stir-fry beef in batches until browned on the outside (1–2 minutes per batch). Transfer to a plate.

  4. Sauté Aromatics: Add a little more oil if needed. Stir-fry garlic, ginger, and onion for 1–2 minutes until fragrant and onions begin to soften.

  5. Add Peppers: Stir in red and green bell peppers. Cook for 2–3 minutes until crisp-tender.

  6. Combine & Sauce: Return beef to the pan. Stir the sauce mixture to recombine and pour it in. Cook for 2–3 minutes until the sauce thickens and coats everything.

  7. Finish & Serve: Drizzle with sesame oil, toss gently, garnish with green onions, and serve over steamed rice.

Notes

Slice beef thinly against the grain for maximum tenderness.
Keep your wok/skillet hot for a quick sear without overcooking.
You can swap beef for chicken or tofu for variation.
