Ingredients for the sauce

Ingredients for the beef

  • 2 lb. beef (flank steak or ribeye)
  • 1/3 cup cornstarch
  • 1 large yellow onion
  • 1/3 cup vegetable oil
  • 1 cloves garlic minced
  • 2 bunches green onion


  • Start off by making the sauce: Mince 1 garlic close and 1 tbsp ginger and cook it in a saucepan filled with 2 tbsp vegetable oil. Cook it over medium-high heat for 1 minute.
  • Add the 1/4 cup brown sugar, 1 cup low sodium soy sauce, and 1/2 cup water. Bring to a simmer and cook over medium-low heat for 5 minutes.
  • Thinly slice the 2 lb. beef into small pieces. Pro tip: place the beef in the freezer 15-20 minutes prior to slicing to make thinner cuts without the meat sliding around.
  • Place the sliced beef in a large bowl and mix it with 1/3 cup cornstarch.
  • Heat 1/3 cup vegetable oil in a 14-inch wok and cook the beef in 2 batches to avoid overcrowding and mushy texture. Once cooked, remove the beef and set it aside.
  • In the same wok, cook 1 clove minced garlic over medium heat for 1 minute. Then add 1 cup sliced yellow onion and cook until translucent.
  • Add the beef back into the wok and pour in the sauce. Bring to a simmer for another 5 minutes.
  • Add 2 bunches of sliced green onion to the beef and stir for about 2-3 minutes. Serve warm over hot rice.


  • Slicing the meat- A great way to get thinly sliced beef is by having the meat partially frozen when you cut it. That way it doesn't slide around and you achieve super thin slices.
  • Cook in batches- In order to get nice and crispy pieces of cooked beef, don't overcrowd the wok. Cook the beef in batches. Overcrowding will cause a lot of liquid to collect and result in mushy grey looking beef.
