Method
- In a bowl, mix soy sauce, cornstarch, and vegetable oil. Add sliced steak and toss to coat. Let marinate for 15–20 minutes.
- In a separate bowl, whisk soy sauce, oyster sauce, rice vinegar, cornstarch, sesame oil, brown sugar, black pepper, and beef broth. Set aside.
- Heat 1 tbsp vegetable oil in a large skillet or wok over high heat. Sear steak in a single layer, 1–2 minutes per side. Remove and set aside.
- Add remaining oil to the skillet. Stir-fry onions and peppers over medium-high heat for 3–4 minutes until tender-crisp.
- Add garlic and ginger, stir-fry for 30 seconds until fragrant.
- Return steak to skillet. Stir sauce and pour over. Cook 1–2 minutes until thickened and evenly coated.
- Transfer to a platter. Garnish with green onions and sesame seeds. Serve hot over steamed rice.
Notes
Use sirloin or skirt steak as alternatives to flank steak. Prep vegetables and marinate meat in advance to save time. Leftovers can be stored for 3 days.
