Equipment

  • 1 large skillet or wok
  • 1 cutting board
  • 1 measuring spoons
  • 1 measuring cup
  • 1 spatula

Ingredients
  

  • 1 lb flank steak, sliced thin against the grain
  • 2 tablespoons soy sauce
  • 2 tablespoons cornstarch
  • 2 tablespoons vegetable oil
  • 3 cloves garlic, minced
  • 1 teaspoon fresh ginger, minced
  • ½ cup green onions, chopped Reserve some for garnish.
  • ¼ cup brown sugar
  • ¼ cup water
  • 1 tablespoon soy sauce (additional)
  • 1 tablespoon sesame oil
  • Salt and pepper To taste.

Instructions
 

  • In a medium bowl, combine the sliced flank steak with 2 tablespoons of soy sauce and 2 tablespoons of cornstarch. Mix well, ensuring the beef is fully coated. Let it marinate for about 10 minutes.
  • Heat a large skillet or wok over medium-high heat and add 2 tablespoons of vegetable oil.
  • Once the oil is hot, add the marinated beef in a single layer. Sear for 2-3 minutes without stirring until browned, then flip and cook for another 2 minutes. Remove the beef from the skillet and set aside.
  • In the same skillet, add the minced garlic, ginger, and chopped green onions. Stir-fry for about 1 minute until fragrant.
  • Add the brown sugar, water, 1 tablespoon of soy sauce, and sesame oil. Stir until the sugar dissolves and the sauce thickens slightly, about 2-3 minutes.
  • Return the beef to the skillet and toss to coat in the sauce. Cook for another 2-3 minutes until heated through. Season with salt and pepper to taste.
  • Remove from heat and serve hot over cooked rice or noodles. Garnish with reserved chopped green onions.

Notes

For a spicier version, add red pepper flakes or sliced chili peppers to the sauce.
If you prefer a thicker sauce, let it simmer for a few extra minutes before adding the beef back in.
This dish pairs well with steamed broccoli or snap peas for added veggies.
