How to Freeze Sweet Potatoes (Whole, Mashed, or Diced)

4  whole sweet potatoes

  1. Wash and dry your potatoes. If baking whole, prick with a fork.
  2. Bake at 400°F for an hour, or until easily poked with a fork.
  3. Let cool completely before freezing in zip-top bags.
  4. Another option is to cut and blanch the potatoes. Simply boil for 5 minutes until they are slightly tender. Dry completely before freezing in a single layer on parchment.
  5. Once completely frozen, add to labeled and dated zip-top bags.


  1. Sweet potatoes are best either partly or fully cooked before freezing – do not freeze raw!
  2. Potatoes will last in the freezer for 10-12 months; be sure to remove as much air from the bag as possible.
