"Mongolian Chicken with Mung Beans was an excellent dish, and quite easy to prepare and cook. Have everything ready, follow the instructions in order, and it comes together easily and quickly.

How to Store and Freeze

  • Refrigerate leftover Mongolian chicken in airtight container within 2 hours and eat within 4 days.
  • To freeze for longer storage, transfer the cooked chicken and sprouts to freezer containers or zip-close freezer bags and freeze for up to 3 months. Defrost the chicken in the fridge overnight.

Why are Mung Bean Sprouts Blanched?

The main reason sprouts are blanched is to kill any harmful bacteria they may be harboring, but it also helps preserve the freshness and crispness. After blanching the sprouts briefly in boiling water, drain them in a colander and run cold water over them to halt the cooking.
