Ingredients

Scale

Beef and Sauce Ingredients

  • 1 lb flank steak, sliced thinly
  • ½ cup soy sauce
  • ½ cup water
  • ¼ cup brown sugar
  • 3 garlic cloves, minced
  • 1 tbsp ginger, grated

Optional Thickener

  • 2 tbsp cornstarch (optional)
  • 2 tbsp water (for cornstarch slurry)

Instructions

  1. Prepare the ingredients: Thinly slice the flank steak against the grain to ensure tenderness. Mince the garlic cloves and grate the fresh ginger.
  2. Combine in the crockpot: Place the sliced flank steak, soy sauce, water, brown sugar, minced garlic, and grated ginger into the crockpot. Stir gently to combine all ingredients evenly.
  3. Cook the beef: Cover the crockpot with the lid and cook on low heat for 4 to 5 hours or until the beef is very tender and the flavors meld.
  4. Thicken the sauce (optional): If you desire a thicker sauce, about 30 minutes before the cooking time is complete, mix the cornstarch with two tablespoons of water to make a slurry. Stir this into the crockpot and continue cooking for the remaining time to allow the sauce to thicken.
  5. Serve: Once cooked, stir well and serve the Mongolian beef hot over steamed rice or your favorite side dishes.

Notes

  • Thinly slicing the beef against the grain helps keep it tender after slow cooking.
  • The cornstarch slurry is optional and used only if you prefer a thicker sauce.
  • To add extra vegetables, consider adding sliced bell peppers or green onions during the last hour of cooking.
  • Brown sugar can be substituted with coconut sugar or honey for a different sweetness profile.
  • This recipe is gluten-free if you use gluten-free soy sauce or tamari.
