What freezing does to roast potatoes
Roast potatoes freeze well: Tesco Real Food says to boil them for 5 minutes, cool and flash-freeze them, keep them up to 3 months, and roast them from frozen without defrosting, because defrosting makes them mushy.

Common questions
How long can you freeze roast potatoes?
For best quality, up to 3 months (Tesco Real Food, UK). They stay safe beyond that, because bacteria cannot grow at a constant -18°C; the limit is about taste and texture. Label the pack with the date.
How should I freeze roast potatoes?
Cool quickly and freeze in portions. Undercook pasta slightly and toss it in a little oil or sauce so it does not stick; freeze potato dishes mashed or roasted rather than boiled whole.
How do I defrost roast potatoes?
In the fridge, or straight from frozen into a soup or sauce. Reheat until piping hot throughout (75°C) — once only.
Can you refreeze roast potatoes?
Do not refreeze once defrosted. Portion small.
Fridge or freezer for roast potatoes?
The fridge window for roast potatoes is up to 2 days (FSA/NHS). If you are not going to finish it inside that window, freeze it while it is still fresh, ideally in the first day or two, since freezing only pauses the clock and anything frozen late goes in with less life left.
Is roast potatoes with freezer burn safe to eat?
Yes. Freezer burn is dried-out, greyish patches where air has reached the surface; it affects texture and flavour, not safety (USDA). Cut away badly affected areas if you like, and prevent it by wrapping tightly and pressing out the air.
