Ingredients

Marinade

  • 1 1/2 pounds flank steak halved lengthwise, then sliced 1/2 inch thick
  • 1/4 cup soy sauce
  • 1 tablespoon sesame oil
  • 1 clove garlic sliced
  • 1 tablespoon brown sugar
  • 1/2 tablespoon crushed red pepper flakes

Sauce

  • 3/4 cup soy sauce
  • 1/4 cup beef broth**
  • 1/2 cup water
  • 1/2 tablespoon crushed red pepper flakes
  • 1/2 teaspoon ground ginger
  • 1/2 cup brown sugar packed
  • 1 tablespoon hoisin sauce
  • 1 tablespoon seasoned rice vinegar
  • 4 cloves garlic minced
  • 1/4 cup cornstarch

Other

  • 1 tablespoon sesame oil
  • Green onions thinly sliced
  • Sesame seeds
  • Cooked rice

Instructions

Marinade

  • In a small bowl whisk together soy sauce, oil, garlic, brown sugar, and red pepper flakes. Set aside.
  • Place sliced steak in a gallon size baggie and pour in marinade.
  • Close and place in fridge for at least 4 hours, but I let mine marinate in the fridge overnight.

Mongolian Beef

  • In a medium sized bowl, whisk together sauce ingredients: soy sauce, broth, red pepper, ginger, brown sugar, hoisin sauce, vinegar, garlic, and cornstarch. Set aside.
  • In a large skillet, heat sesame oil over medium high heat.
  • Once hot, add in marinated steak.
  • Cook steak for about 2-5 minutes, or until nicely browned.
  • Pour in sauce, raise heat to high and cook until sauce has thickened and steak is cooked to you liking.
  • Serve immediately over rice and top with sliced green onions, sesame seeds, and more crushed red pepper flakes.
  • Take 5 seconds to rate this recipe below. We greatly appreciate it!

Notes

*This recipe is on the salty side, but that's how Trevor and I like our Mongolian beef! If you're not a salty fan, feel free to use low sodium soy sauce and low sodium beef broth. You could also replace the beef broth with water and season with salt, if necessary after cooking.
