Essential Ingredients

  • 1 1/2 pounds flank steak, thinly sliced against the grain Make sure it’s well-marbled for better flavor.
  • 1/4 cup cornstarch Coats the beef for perfect texture.
  • 1 tablespoon toasted sesame oil Use a high-quality brand like Kadoya.
  • 1 teaspoon minced garlic Fresh is ideal.
  • 1 teaspoon minced ginger Fresh is best, but squeeze tubes work for convenience.
  • 1/2 cup low sodium soy sauce Helps manage sodium levels without sacrificing flavor.
  • 1/3 cup brown sugar Balances the saltiness of the soy sauce.
  • 1/2 cup water Helps create the sauce while the meat cooks.

  • Ensure your flank steak is at room temperature before slicing.
  • In a mixing bowl, toss the flank steak with cornstarch until evenly coated.

Cooking

  • Cover and cook on HIGH for 2-3 hours or LOW for 4-5 hours.

  • Just before serving, stir in green onions.
