Sweet potatoes have a high water content. This means that if you freeze them raw, they can very easily get freezer burned, and turn mushy or mealy when thawed. It is not recommended that you freeze raw potatoes because they just won’t act right in recipes nor will they taste their best.

If you want to freeze a whole sweet potato, then it’s also important to cook it first. Instead of blanching it whole, though, you’ll need to roast it completely. Then, you can let the potato cool and freeze it whole with its skin or without its skin.

Blanching is a way to preserve many vegetables, and it’s a great way if you are planning to dice your sweet potatoes to use later in Sweet Potato Hash or wedge them for Sweet Potato Fries.

By blanching your sliced or diced sweet potatoes, you are basically just taking the raw “bite” out of them before freezing. This way, when you go to use them in a recipe, you cut off some of the cooking time and still achieve the perfect texture.

Let’s go into the details on the best way to freeze sweet potatoes whole, mashed, or diced.

Steps on Freezing Whole Sweet Potatoes

Yes, you can freeze whole sweet potatoes! But, you’ll need to roast them first. Let me show you how.

Step One

Scrub potatoes well, prick with a fork, and place on a baking sheet.

Step Two

Bake potatoes for an hour at 400°F, or until they can easily be pricked with a fork.

As always, please do see the recipe card at the end of this post for the exact ingredients and measurements.

Step Three

Let cool completely to room temperature. At this point you can leave the skin on or remove the skin from the baked sweet potato.

Step Four

Wrap each cooked and cooled baked sweet potato in aluminum foil and then place them in a labeled and dated zip-top freezer bag. Wrapping them in foil will help retain the moisture in the potato and keep it from drying out. Store for 10-12 months.

Other Methods

There are actually several different ways to freeze sweet potatoes.

How to Freeze Mashed Baked Sweet Potatoes

You can also peel and mash up your fully baked sweet potatoes and freeze them that way. I like to make Instant Pot Mashed Sweet Potatoes as the easiest and fastest method.

Don’t season them before freezing, but wait until you defrost and serve them to add seasonings. For best results, place your sweet potato puree in quart size resealable freezer bags to freeze flat.

Use your mashed sweet potatoes in a Sweet Potato Casserole or as the topping on a Sweet Potato Shepherd’s Pie.

How to Freeze Diced or Sliced Sweet Potatoes

If you prefer to freeze your sweet potatoes sliced or diced, you can do that too. Before freezing the diced, sliced, or wedged sweet potatoes, you’ll need to blanch them in a large pot of boiling water for 5 minutes.

By freezing diced sweet potatoes, they will be perfect for hash browns or french fries. Another great option is to slice them into rounds and freeze them after blanching them.

Always freeze your blanched or baked sweet potatoes in a single layer on a parchment-lined baking sheet before adding to an airtight freezer bag, or you risk all your hard work being frozen into a single lump.

Expert Tips

  • You can use this cooking process for blanching and freezing sweet potatoes with white potatoes too!
  • If you don’t have time to prep your sweet potatoes for freezing right now, be sure to store them in a dark place like a pantry until you’re ready to cook them.


How long can you freeze sweet potatoes?

Frozen sweet potatoes will last for 10-12 months. Be sure to get as much air out of the zip-top bags as possible.

How do you blanch sweet potatoes?

Blanching means putting your cut potatoes into boiling water for 5 minutes or so, until just barely tender. Be sure to drain and dry completely before freezing.

How do you thaw frozen sweet potatoes?

Frozen potatoes are best thawed in the fridge to help retain their moisture and texture, though you can also often use them straight from frozen.

How do you reheat frozen sweet potatoes?

Use in any of your favorite recipes! The oven will be best for giving them a crispy outer texture, especially if you have pre-cut them. Just keep in mind that they have been parcooked, so you will need to cut some cooking time out of your recipe. It is easy to simply roast them with some olive oil and salt and watch for them to be done.

Can you freeze raw sweet potatoes?

Raw potatoes are not a good idea to freeze due to their high water content. They will easily attract freezer burn and can become mushy or mealy when thawed.
