How Long Leftovers Keep in the Fridge: 2 Hours, 4 °C, 3 to 4 Days
Cooked food goes into the fridge within 2 hours, sits at 4 °C (40 °F) or below and is eaten within 3 to 4 days, soups within 2 to 3. A table by dish, cooling, freezing and reheating.
Cooked food may stay at room temperature for no more than 2 hours; at 4 °C (40 °F) or below, leftover meat, stews and egg or vegetable dishes keep 3 to 4 days, and soups 2 to 3 days. The 2-hour limit is stated both by the Croatian Agency for Agriculture and Food (HAH) in its "5 keys to food safety" and by the FDA, and the fridge days come from Health Canada's storage table. The FDA adds why the limit is so sharp: at room temperature the number of bacteria that cause foodborne illness can double every 20 minutes, and when the air is warmer than 32 °C (90 °F) the limit drops to 1 hour.
How many days for which dish
Health Canada publishes its table on the condition that the refrigerator is at 4 °C (40 °F) or lower and the freezer at −18 °C (0 °F). HAH gives "preferably below 5 °C" for the fridge. Freezer times refer to quality, not safety: food at −18 °C stays safe, but after the months listed it loses texture and flavour.
| Leftovers | Refrigerator (≤ 4 °C / 40 °F) | Freezer (−18 °C / 0 °F) |
|---|---|---|
| Cooked meat, stews, egg or vegetable dishes | 3–4 days | 2–3 months |
| Cooked poultry and fish | 3–4 days | 4–6 months |
| Meat broth and gravy | 3–4 days | 4–6 months |
| Soups | 2–3 days | 4 months |

Cooling: shallow containers, not the full pot
The FDA advises dividing leftovers into smaller containers before refrigerating, because hot food cools faster in them. A full pot of goulash stays warm in the centre for hours and spends all that time in the range where bacteria multiply. In practice: transfer the food to shallow lidded containers, let the steam escape and refrigerate before 2 hours have passed since cooking. A thermometer in the fridge shows whether it really is at 4 °C; the FDA names that instrument as the only reliable check. Label containers with the date, because the 3-to-4-day clock starts at cooking, not when the fridge door opens.
Freezing and thawing
If leftovers will not be eaten within 3 to 4 days, HAH advises cooling them, packing them in containers and freezing within a few hours of preparation, not on the last day of their shelf life. For thawing the FDA lists three safe methods: in the refrigerator, in cold water and in the microwave; HAH recommends slowly overnight in the fridge or in the microwave. Thawed leftovers do not get a new shelf life: HAH states that previously prepared food, once thawed, should be eaten within 24 hours of thawing. Never thaw leftovers on the counter overnight, because the outer layer sits at room temperature for hours while the centre is still frozen.
Reheating to 70 °C
HAH's "5 keys" state that food such as soup or stew should be brought to the boil and reach 70 °C (158 °F). The same rule applies to reheated leftovers: bring sauces, stews and risotto to the boil and stir so the centre heats through, and stir microwaved dishes halfway through because microwaves heat unevenly. Reheat only the portion you will eat; food that is cooled and reheated several times passes through the bacterial growth range every single time.
Smell is not a test
Health Canada is explicit: you cannot tell if food is unsafe by its smell or taste; when in doubt, throw it out. The bacteria that cause food poisoning do not change the smell of food, unlike spoilage bacteria that do, so a five-day-old dish can smell perfectly normal. The times in the table therefore apply even when the food looks fine. To have fewer leftovers, cook portions for the number of people at the table; recipes with per-person quantities are in the recipes section, and more storage guides are on the blog.
