How to Store / Freeze This Dish
Allow the sweet potatoes to cool completely at room temperature before storing. This helps to prevent condensation, which can make them soggy.
Transfer the cooled sweet potatoes to an airtight container or a resealable plastic bag. Make sure to remove as much air as possible to maintain their texture and flavor.
