Yes, you can freeze sweet potatoes. The simplest and most reliable method is to freeze them cooked: baked, boiled, mashed or roasted portions reheat well for soups, mash, pies, curries and side dishes. Raw pieces need a brief blanch first for a better freezer result.

Step-by-step method
- Choose firm sweet potatoes with no mouldy or deeply damaged patches.
- For the easiest method, bake, boil, steam or roast them until just tender, then cool them promptly.
- Mash them, slice them, or cut them into the portion size you normally use in meals.
- For raw pieces, peel and cut them, blanch briefly in boiling water, then cool quickly in cold water and dry well.
- Pack cooled portions into labelled airtight containers or freezer bags, removing excess air where practical.
- Thaw in the fridge or reheat from frozen in a hot dish until piping hot throughout.
Is it better to freeze sweet potatoes raw or cooked?
Cooked sweet potatoes are usually the easiest option because they reheat well and need less preparation later. If you freeze raw pieces, blanch them first, cool them quickly and dry them before packing to help preserve their quality.
Can you freeze mashed sweet potatoes?
Yes. Cool mash promptly, divide it into meal-sized portions and freeze it airtight. Reheat gently, stirring in a little butter, milk or water if the texture needs loosening.
Can you freeze roasted sweet potatoes?
Yes. Cool roasted cubes, wedges or halves, freeze them separately on a tray if you want loose pieces, then transfer them to an airtight bag. Reheat in the oven, air fryer or a hot pan rather than expecting the same crispness as freshly roasted sweet potatoes.
