# How to Prepare:

01 - In a bowl, combine beef slices with soy sauce, cornstarch, rice wine, and sesame oil. Toss to coat evenly and allow to marinate for 10 minutes.
02 - In a small bowl, whisk together soy sauce, oyster sauce, hoisin sauce, chili garlic sauce, sugar, and water. Set aside.
03 - Heat 1 tablespoon vegetable oil in a large wok or skillet over high heat. Add marinated beef and stir fry for 2 to 3 minutes until browned but not fully cooked through. Transfer beef to a plate and set aside.
04 - Add remaining 1 tablespoon oil to the pan. Stir fry garlic, ginger, and onion for 30 seconds until fragrant and the aromatics begin to release their oils.
05 - Add sliced bell peppers to the pan and stir fry for 2 to 3 minutes until tender but still crisp with slight color retention.
06 - Return beef to the pan. Pour sauce mixture over the ingredients and stir well to combine thoroughly. Cook for 1 to 2 minutes until beef reaches desired doneness and sauce thickens slightly.
07 - Remove from heat immediately. Garnish with sliced spring onions and serve straight away, preferably accompanied by steamed jasmine or basmati rice.

# Expert Advice:

01 -
  • The marinade takes just seconds to throw together, but creates that authentic restaurant-quality tenderness in the beef that I could never figure out before.
  • Everything cooks in one pan, meaning youll spend more time enjoying dinner and less time scrubbing dishes afterward.
02 -
  • The sequence matters tremendously, cook meat first then remove it, otherwise youll end up with overcooked beef by the time your vegetables are done.
  • Cornstarch in the marinade creates that velvety restaurant-quality texture, not fancy ingredients or equipment.
03 -
  • Freeze the beef for about 15 minutes before slicing it will help you get those restaurant-quality thin slices that cook perfectly in seconds.
  • Keep everything moving constantly in the wok rather than stirring occasionally, this prevents burning and ensures even cooking in that intense heat.
