04 - 2 cloves garlic, minced
05 - 1 tablespoon fresh ginger, grated

# Cooking steps:

01 - Combine sliced beef, soy sauce, Shaoxing wine, sesame oil, white pepper, and cornstarch in a bowl. Mix thoroughly to coat and marinate for at least 10 minutes.
02 - Whisk together soy sauce, oyster sauce, hoisin sauce, brown sugar, and water in a small bowl until smooth. Set aside for later use.
03 - Heat 2 tablespoons vegetable oil in a large skillet or wok over high heat. Add marinated beef in a single layer and sear for 2-3 minutes until crispy and browned. Remove beef to a plate and reserve.
04 - Add remaining oil to the pan. Sauté onion, garlic, and ginger for 2-3 minutes until fragrant and onions are slightly caramelized.
05 - Return beef to the pan. Pour in prepared sauce and toss everything together for 1-2 minutes until heated through and evenly coated.
06 - Sprinkle with sliced spring onions. Serve immediately over steamed jasmine rice or noodles.

# Tips from flavorandfeast:

01 -
  • The beef develops this incredible crispy exterior while staying tender inside, exactly like your favorite takeout spot but better because you made it
  • Everything comes together in under 30 minutes, including the marinade time, making it perfect for those evenings when takeout sounds too exhausting
02 -
  • Crowding the pan while searing the beef will make it steam instead of crisp, so work in batches if your pan is not big enough
  • The sauce thickens incredibly fast in the hot pan, so have your serving platter ready before you pour it in
03 -
  • Freeze the flank steak for 20 minutes before slicing, it becomes firm enough to cut those paper-thin slices with ease
  • The beef will continue cooking slightly in the hot sauce, so remove it from the heat while it still looks slightly underdone
