Amazing Mongolian Beef


  • 1 1/2 pounds flank steak sliced thin (I used pre-sliced stir fry steak)
  • 1/4 cup cornstarch
  • 3 Tablespoons vegetable oil
  • 1/2 cup soy sauce
  • 1/2 cup brown sugar
  • 1/4 cup water
  • 1 teaspoon minced ginger
  • 3 garlic cloves minced
  • 1/2 sliced onion
  • green onions cut into thirds
  • pinch of red pepper flakes


  • Heat some oil in a skillet and cook all of your onions.  I like mine charred.  Set aside.
  • In a large ziplock bag add the steak and cornstarch. Toss the beef to coat evenly. Heat a large skillet to high heat and add the vegetable oil. Once your pan is sizzling HOT, add your steak in a single layer and cook on each side for about a minute until the edges just start to brown (get those edges crispy)! Once the steak is cooked, remove and set aside on a plate.
  • In a small mixing bowl combine soy sauce, brown sugar, water, ginger, and garlic. Add the sauce to the pan and bring to a boil. Add the steak and cooked onions to the sauce and allow the sauce to thicken for a couple of minutes. Sprinkle with red pepper flakes.
  • Serve with rice or fry some Mung Bean noodles in hot oil for the traditional crispy noodle.
