Step-by-step method
- Decide whether the potatoes are raw, blanched, boiled, mashed or roasted.
- For raw potato pieces, blanch them briefly and dry them well before freezing.
- Cool cooked potatoes quickly and remove excess moisture.
- Freeze portions on a tray first if you want separate pieces.
- Move frozen pieces or portions into labelled freezer bags or containers.
- Reheat until steaming hot throughout, adding a little fat or moisture if texture looks dry.
Can you freeze raw potatoes?
Raw potatoes are not the best freezer candidate because the texture can become watery, sweet and grainy. If you want to freeze uncooked pieces, blanching first is the safer route.
Best potatoes to freeze
Mashed potatoes, roast potatoes, boiled potatoes and cooked potato dishes usually freeze better than raw slices. Let them cool, dry the surface where possible and freeze in useful portions.
How to use frozen potatoes
Use frozen potatoes for mash, soups, hash, tray bakes, roast-potato sides and quick leftovers. Texture matters less in dishes where the potato is reheated with sauce, gravy or fat.
