The most recommended method for storing raw cut sweet potatoes both long and short-term which can last anywhere between a week to up to 2 months.
Frozen raw sweet potatoes can last anywhere from six months up to a year in a deep freezer, but I would consider that pushing the limits! Eat it sooner than later.
With this storage method, the raw cut sweet potatoes can last between 24 hours and up to a few days – but no more than that.
Once you’ve freeze-dried your sweet potatoes, test them for moisture and then seal them in a Mylar bag (with an oxygen absorber) for up to 25 years. Note - this does require that you have a freeze dryer!
An additional tip for selecting the best sweet potatoes to store is to choose those that are newly harvested and still have the roots attached.
These tend to be a better choice because of their freshness and the plumper they are, the longer they’re expected to store and have the best results.
