Recipe Notes:

Flank Steak: Slice against the grain into thin strips for optimal tenderness.

Cornstarch Coating: Tossing the beef in cornstarch before cooking helps thicken the sauce and gives the beef a velvety texture.

Cooking Time: For best results, cook on LOW for 4–5 hours to achieve tender beef.

Serving Suggestions: Serve over steamed white or jasmine rice. Garnish with additional sliced green onions and sesame seeds for added flavor and presentation.

Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently to avoid overcooking the beef.
