Ingredients

Scale
  • 1.5 pounds flank steak or sirloin, thinly sliced against the grain
  • 2 tablespoons vegetable oil
  • 3 cloves garlic, minced
  • 1 tablespoon freshly grated ginger
  • ½ cup low sodium soy sauce
  • ⅓ cup brown sugar, packed
  • ½ cup water
  • 4 green onions, sliced thinly, for garnish
  • 2 tablespoons cornstarch mixed with 2 tablespoons water (for thickening)
  • ¼ teaspoon red pepper flakes (optional)

Instructions

  1. Slice 1.5 pounds of flank steak thinly against the grain, about ¼ inch thick. Set aside.
  2. In a small bowl, whisk together ½ cup soy sauce, ⅓ cup brown sugar, ½ cup water, 3 minced garlic cloves, 1 tablespoon grated ginger, and optional ¼ teaspoon red pepper flakes.
  3. Turn Instant Pot to ‘Sauté’ setting and heat 2 tablespoons vegetable oil. Add garlic and ginger, stirring for about 30 seconds until fragrant.
  4. Add sliced beef in batches and sauté for 2-3 minutes until it just starts to brown but isn’t cooked through.
  5. Pour the prepared sauce over the beef in the pot. Stir gently to combine. Secure the lid, set valve to sealing, and cook on ‘Manual’ high pressure for 10 minutes.
  6. Allow a natural pressure release for 5 minutes, then carefully switch valve to venting to release remaining steam.
  7. Open lid and switch back to ‘Sauté.’ Stir in cornstarch slurry and simmer for 2-3 minutes until sauce thickens and clings to the beef.
  8. Stir in sliced green onions and serve over steamed rice or noodles.

Notes

Do not skip the natural pressure release step to keep beef juicy. Slice beef thin and against the grain for tenderness. Work in batches when browning beef to avoid overcrowding. Use fresh garlic and ginger for best flavor. Adjust sweetness and saltiness to taste after cooking. Thicken sauce gradually to avoid lumps.
