How long do leftovers last in the fridge? (And why rice is different)
The short answer: eat most cooked leftovers within two days, and cooked rice within one. Get them into the fridge within two hours of cooking (rice within one hour), keep the fridge at 5 °C or below, and reheat until steaming hot all the way through. If you won’t get to them in time, freeze them.
That covers almost every Sunday-roast, big-pot-of-chilli, takeaway-for-two situation. The rest of this page explains the numbers, why rice gets its own rule, and what to do when two days clearly isn’t going to happen.
Two days, give or take a day
The UK Food Standards Agency is direct: “Eat leftovers within 48 hours or freeze them if you think this won’t be possible.”
The European Food Information Council (EUFIC) is a little more generous and says 2–3 days. Both are mainstream food-safety advice. The difference is a margin, not a disagreement about whether the chilli is safe. If you want one number to remember, use the stricter one: two days.
Why so short, when the fridge feels like a safe place? Because cold slows bacteria down but doesn’t stop them. EUFIC puts it plainly: microbes “can still grow at low temperatures, although more slowly.” And the bacteria that cause food poisoning don’t usually change how food looks or smells, so leftovers can pass the sniff test and still be past it.
Why rice gets its own rule
Cooked rice is the one leftover that comes with a one-day limit. EUFIC and the FSA agree on this.
The reason is a bacterium called Bacillus cereus. Uncooked rice can carry its spores, and the spores survive cooking. If cooked rice isn’t cooled quickly and stored properly, they can grow into bacteria that produce toxins. EUFIC explains that “the longer cooked rice is kept, the more likely it is that the bacteria will make it unsafe to eat.”
So the FSA’s rice advice is stricter at every step:
- Chill it fast: “ideally within one hour.”
- Keep it briefly: “no more than one day until reheating.”
- Reheat it once: “never reheat rice more than once,” and make sure it’s “steaming hot all the way through.”
That goes for rice dishes too: the leftover paella, risotto and egg-fried rice all count.
Cool it quickly, but not on the counter overnight
The clock starts when the food comes off the heat, not when it goes in the fridge.
- Two hours is the limit at room temperature. EFSA: “Don’t leave cooked food at room temperature for more than 2 hours.” The FSA says to get cooked food into the fridge “within one to two hours.”
- Don’t put it in piping hot. EUFIC says hot food “will raise the temperature of the fridge,” and that’s bad news for everything else on the shelf. Let it cool to room temperature first.
- Speed it up when you need to. EUFIC suggests standing the pot in cold water, uncovered so the steam can escape, then moving the food into an airtight container once it has cooled.
Reheating: steaming hot, and only once for some foods
When you reheat leftovers, the FSA’s test is that the food is steaming hot all the way through, not just at the edges.
How many times can you reheat leftovers? The FSA gives two firm limits:
- Rice: never more than once.
- Cooked and then frozen meat: “should only be reheated once.”
The simplest habit is to reheat only the portion you’re going to eat and leave the rest in the fridge.
When two days won’t happen: freeze it
Freezing is the FSA’s own fallback, in the same sentence as the 48-hour rule. A few things make it work:
- Freeze it early, not on day two as an afterthought. Cool it first: the FSA says to “cool any warm dishes before putting them in your freezer.”
- Keep the freezer at −18 °C (FSA, EUFIC).
- Defrost in the fridge, not on the counter (FSA, EFSA).
- Eat it within 24 hours of it being fully defrosted (FSA).
- Don’t refreeze defrosted food unless you’ve cooked it in between (EUFIC).
How long does it keep in the freezer? Freezing keeps food safe, but EUFIC notes that quality drops “after 3–12 months depending on the product.” Write the date on the box. You won’t remember it.
A quick reference
| Food | In the fridge | Notes |
|---|---|---|
| Cooked leftovers | 2 days (FSA) · 2–3 days (EUFIC) | Fridge within 2 hours of cooking |
| Cooked rice and rice dishes | 1 day | Chill within 1 hour; reheat once only |
| Food you cooked on its use-by date | 2 days | See use by vs best before |
| Defrosted food | Within 24 hours | Defrost in the fridge |
| Anything with “once opened, eat within…” | Whatever the pack says | That line overrides the printed date |
Is your fridge cold enough?
Every number above assumes a properly cold fridge. The FSA says 0–5 °C; EUFIC says below 4 °C. Most fridges have a dial, not a display, so the only way to know is a fridge thermometer, which costs a few euros. Put it on a middle shelf and check it once.
Frequently asked questions
Can you eat leftovers after 3 days?
The FSA’s limit is 48 hours; EUFIC’s is 2–3 days. Past three days, neither source supports eating them. Food can look and smell fine and still carry enough bacteria to make you ill, so the safer choice is to freeze leftovers you won’t finish within two days.
Can you reheat leftovers twice?
Not rice: the FSA says never reheat it more than once. The same goes for meat that was cooked and then frozen. For everything else, the safest habit is to reheat only the portion you’re about to eat, until it’s steaming hot all the way through, and leave the rest in the fridge.
Is it safe to put warm food in the fridge?
Let it cool to room temperature first, but don’t leave it out for more than two hours. EUFIC explains that hot food raises the fridge’s temperature for everything around it. To cool a big pot quickly, stand it in cold water, uncovered.
How long do leftovers last in the freezer?
Kept at −18 °C, frozen leftovers stay safe, but EUFIC says the quality starts to fade after 3 to 12 months, depending on the food. Label the container with the date. Defrost it in the fridge and eat it within 24 hours.
Where Nudgey fits
Two days goes fast when nobody is counting. Leftovers are the easiest thing in the kitchen to forget: there’s no label and no printed date, just a tub at the back of the fridge.
Nudgey keeps your fridge, freezer and pantry in one list, sorted by what to use first. Add the leftovers with a date two days out, and Nudgey sends you a nudge when they’re due, never more than one a day. It also shows you recipes that use what you already have, which helps with the half-tin of tomatoes left over from the chilli.
Nudgey tracks the date you give it. It isn’t a food-safety authority. The guidance above and the label on the pack always win.
Nudgey is coming soon to iPhone. It starts with a 7-day free trial, then it’s a subscription. Your inventory stays on your phone.
