Main Ingredients

Vegetables

Method

Preparation

  1. 1

    Slice the Flank Steak

    Thinly slice the flank steak against the grain into strips. This helps make the meat tender.

  2. 2

    Marinate the Beef

    In a bowl, combine the soy sauce, brown sugar, and cornstarch. Add the sliced beef to the marinade and let it sit for at least 30 minutes.

Cooking

  1. 3

    Prepare the Vegetables

    While the beef is marinating, chop the green onions and mince the garlic and ginger.

  2. 4

    Heat the Oil

    In a large skillet or wok, heat the vegetable oil over medium-high heat until hot.

  3. 5

    Cook the Beef

    Add the marinated beef to the skillet in a single layer. Cook for 2-3 minutes without stirring to let it sear, then stir-fry until browned and cooked through, about another 2-3 minutes.

  4. 6

    Add Aromatics

    Add the minced garlic, ginger, and red chili flakes to the skillet with the beef. Stir-fry for another 1-2 minutes until fragrant.

  5. 7

    Add Green Onions

    Stir in the chopped green onions and cook for an additional minute until they are tender but still vibrant.
