Ingredients Method Notes

Ingredients
  

  • 1½ pounds flank steak thinly sliced against the grain
  • ¼ cup cornstarch
  • 1 tablespoon sesame oil
  • 1 teaspoon minced garlic
  • 1 teaspoon minced ginger
  • ½ cup low-sodium soy sauce
  • ⅓ cup brown sugar
  • ½ cup water
  • ½ cup green onions cut into ½ inch pieces

Method
 

  1. In a medium bowl, toss sliced flank steak with cornstarch to coat evenly.
  2. Add sesame oil, garlic, ginger, soy sauce, brown sugar, and water into the slow cooker. Stir well.
  3. Add the coated steak to the slow cooker and stir to combine with the sauce.
  4. Cover and cook on LOW for 4–5 hours or on HIGH for 2.5–3 hours.
  5. Stir in green onions 10–15 minutes before serving.
  6. Serve hot over rice, noodles, or steamed vegetables.

Notes

  • For easier slicing, partially freeze the steak for 30 minutes beforehand.
  • For a thicker sauce, stir in a cornstarch slurry (1 tbsp cornstarch + 1 tbsp water) during the last 20 minutes.
  • Add broccoli, carrots, or bell peppers during the last hour for a veggie-packed version.
  • Great for meal prep—refrigerate for up to 4 days or freeze for up to 3 months.
