Main ingredients

  • 1.5 pounds flank steak, thinly sliced against the grain Flank steak can be substituted with skirt steak or sirloin.
  • 1/4 cup cornstarch Helps the sauce cling to the meat.
  • 1 tablespoon toasted sesame oil Adds flavor to the dish.
  • 1 teaspoon minced garlic Fresh or jarred garlic can be used.
  • 1 teaspoon minced ginger Fresh ginger is preferred for flavor.
  • 1/2 cup low sodium soy sauce Use low sodium to keep the dish healthier.
  • 1/3 cup brown sugar Adjust based on desired sweetness.
  • 1/2 cup water
  • 1/2 cup green onions, for garnish Add just before serving.

Instructions
 

Preparation

  • Toss the flank steak with cornstarch in a mixing bowl until evenly coated.
  • Place the coated steak in a slow cooker and add sesame oil, garlic, ginger, soy sauce, brown sugar, and water. Stir gently to combine.

Cooking

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

Notes

Slice the steak thinly against the grain for tenderness. If the sauce is too thin after cooking, thicken with cornstarch mixed into cold water. Taste and adjust sweetness or saltiness before serving.
