It’s best to freeze bao after cooking because freezing them before cooking complicates the cooking process and means it’s easy to overcook them.
Leave the steamed buns to cool down to room temperature.
Place the buns on a parchment-paper-lined baking tray. Spread them out to make sure they’re not touching.
Place the baking tray in the freezer for 1-2 hours.
After 2 hours, place the buns in an airtight container or heavy-duty freezer bag.
Label the container and return to the freezer.
Bao can last up to 4-6 weeks in the freezer before the quality will start to deteriorate. However, they’ll remain safe to eat long after this time (as long as the freezer is kept below 0 degrees Fahrenheit).
It’s very important that you let the bao cool before you freeze them. Otherwise the excess water will ruin their texture in the freezer.
