How to Store Sweet Potatoes so They Last Longer (1)

How to Store Uncooked Sweet Potatoes

As a sturdy root vegetable, the sweet potato is relatively easy to store. It's best to keep sweet potatoes in a cool, dry area that gets good ventilation, according to the U.S. Sweet Potato Council.

You really shouldn't store sweet potatoes in the fridge if you plan to eat them within a month or so, as refrigeration can bring on an unpleasant taste and a hard center. They technically will last longer if they're refrigerated, but they just won't taste great.

How to Store Cooked Sweet Potatoes

Once they've been cooked, however, they should go in a shallow airtight container or zip-top bag in the fridge. They'll stay good there for about five days.

Tip: You shouldn't leave cooked sweet potatoes at room temperature for more than two hours, as this can promote bacteria growth and cause foodborne illness.

How to Reheat Cooked Sweet Potatoes

Simply reheat baked or roasted sweet potatoes in the microwave (in 30-second intervals, checking between intervals) or in the oven until they're heated through in the center. You may want to reheat mashed sweet potatoes on the stovetop instead of the microwave so they don't get rubbery. Stir in a little bit of water or cream if need be.

Freezing Sweet Potatoes

Can You Freeze Sweet Potatoes?

Yes, you can (and should!) freeze sweet potatoes. Frozen sweet potatoes work great in soups, stews, and casseroles.

How to Freeze Sweet Potatoes

You can freeze cooked sweet potatoes in three ways: whole, sliced, or mashed. No matter which way you choose, they'll last in the freezer for about one year.

To freeze whole sweet potatoes:

  1. Scrub the sweet potatoes, pierce them in a few places, and bake them at 425 degrees F (220 degrees C) for about an hour (read our definitive sweet potato baking guide).
  2. Once the spuds have cooled completely to room temperature, you can wrap them individually in foil, place them in zip-top freezer bags labeled with the date, and freeze.

To freeze sliced sweet potatoes:

  1. Scrub the sweet potatoes and then boil until tender, about 35 to 40 minutes (start checking them after 25 minutes since potatoes vary in size). Drain them in a colander and let them cool completely before peeling and slicing them.
  2. Arrange the slices in an even layer on a parchment-lined baking sheet, cover, and freeze overnight.
  3. Transfer the frozen slices to a zip-close freezer bag labeled with the date and store in the freezer.

To freeze mashed sweet potatoes:

  1. Boil or bake peeled and cubed sweet potatoes until tender.
  2. Mash the cubes with a potato masher, but don't add butter or milk at this point. Instead of freezing them with dairy, add a tiny bit of lemon juice before mashing. This will keep the mash from turning brown.
  3. Let the mash cool completely before transferring it to freezer bags labeled with the date. We recommend freezing the mash in individual servings so you don't have to thaw and refreeze it multiple times.
