How Long Do Cooked Potatoes Last in the Fridge?
Written by Jordan Morley · Storage times from FSA and NHS guidance (fridge limit) and Love Food Hate Waste / Tesco Real Food (freezer) · Last updated 28 October 2026
Cooked Potatoes keep up to 2 days in a fridge running at 0–5°C.
Storage tips for cooked potatoes
- Fridge at 0–5°C. A fridge thermometer is the cheapest food-safety upgrade — many home fridges run warmer than their dial suggests.
- UK FSA and NHS advice is to eat chilled cooked leftovers within 2 days of cooking. The USDA FoodKeeper figure is 3–4 days; we use the stricter UK limit, and the clock starts when the food is cooked, not when you open the container.

How long: UK and US sources compared
| Source | Fridge life of cooked potatoes | Notes |
|---|---|---|
| Love Food Hate Waste (UK) | 2 days (and up to 3 months in the freezer) | Includes mash. Airtight container |
| Food Standards Agency (general leftovers) | 48 hours, or freeze | Not potato-specific |
| Love Food Hate Waste NZ, Feb 2026 | Cold cooked dishes such as potato salads within 2 days; dishes you will reheat within 4 days | General leftovers, New Zealand |
| Tasting Table, 22 Oct 2023 (US, citing USDA) | 3 to 4 days for boiled potatoes | Fridge at or below 40°F (4°C) |
We use 2 days: it is the UK figure for cooked potatoes specifically (Love Food Hate Waste) and matches the FSA's general 48 hours. The clock starts when the potatoes are cooked.
By form
| Form | What the sources say |
|---|---|
| Boiled | Cool first, then airtight container or resealable bag, pressing out the air (Tasting Table) |
| Mashed | Love Food Hate Waste groups mash with other cooked potatoes: 2 days in the fridge. Food Safety News says refrigerate within two hours |
| Baked / jacket | Food Safety News (US): remove the foil before refrigerating, because foil keeps oxygen out and the botulism warning applies if a foil-wrapped potato is left warm. The UK sources we read do not mention foil |
| Potato salad | Love Food Hate Waste NZ: cold cooked dishes such as potato salads, within 2 days |
| Roast | No source we read gives a separate figure for roast potatoes; treat as cooked leftovers, 2 days |

Using them up
Reheat once until steaming hot all the way through (see reheating roast potatoes). If you will not finish them in 2 days, freeze them: both UK sources that cover cooked potatoes give up to 3 months, and Love Food Hate Waste says to defrost fully in the fridge and use within 24 hours.

Common questions
How long do cooked potatoes last in the fridge?
Up to 2 days in a fridge running at 0–5°C (Food Standards Agency (FSA) / NHS guidance). After that, quality and safety both start to slip, and because the bacteria that cause food poisoning are invisible, ‘it seems fine’ is not a reliable test. When in doubt, throw it out.
How can I tell if cooked potatoes have gone off?
Smell and appearance are unreliable here: the bacteria that matter in cooked dishes (including Bacillus cereus in rice and pasta) often do not change how food smells or looks. Mould, sliminess or a sour smell are obvious reasons to bin it, but a dish can be unsafe without them.
Can I freeze cooked potatoes to keep them longer?
Yes. For best quality, freeze them for around 3 months; they stay safe beyond that because freezing halts bacterial growth, and only texture and flavour decline.
Does my fridge temperature really matter?
Yes. These times assume a fridge at 0–5°C, which is what the Food Standards Agency says to set it to. Bacteria grow faster in a warmer fridge, and many fridges run warmer than their dial suggests, so a cheap fridge thermometer is worth having.
Why do the US sites say 3 to 4 days for cooked potatoes?
Tasting Table cites USDA guidance of 3 to 4 days for boiled potatoes. UK sources we read give 2 days (Love Food Hate Waste, and the FSA's 48 hours for leftovers). We follow the UK figure.
Should I take the foil off a baked potato before putting it in the fridge?
Food Safety News, a US site, says to remove the foil first and to refrigerate within two hours, because a foil-wrapped potato left warm is a botulism concern. No UK source we read says this, but removing the foil costs nothing.
