Freeze cooked leftovers only if you handled them safely before freezing. Set aside the portion you want to keep, divide it into clean shallow containers and cool it promptly. Keep the freezer at −18°C or below. Mark what is in each container and when it was cooked so you can find the oldest portion first.
Freezing cannot undo time spent at an unsafe temperature. If a perishable dish sat warm for hours or you cannot establish how it was handled, discard it. Cooked rice needs particular care, so follow the separate rice guidance when freezing a rice dish.
- Set aside suitable portions early.
- Use clean shallow freezer-safe containers and label them.
- Keep the freezer at −18°C or below.
- Thaw and reheat only what you plan to eat.

Choose what can go into the freezer
Start with freshly cooked food you have handled safely. SFA advises apportioning cooked food intended for another meal into clean covered containers. Freeze portions promptly after rapid cooling. Follow more specific directions if the recipe, seller or ingredient label gives them. SFA’s household food safety guidance
| Situation | What to do |
|---|---|
| Freshly cooked stew you intend to save | Divide into meal-size portions and cool promptly |
| Food left warm for hours | Discard it |
| Cooked rice | Follow rice-specific cooling and freezing guidance |
| A container without a date | Label it when packing so you can identify it later |
| One meal needed tomorrow | Thaw only the portion you will use |

Pack small portions you can identify
Use a clean freezer-safe container that seals properly. Choose a shallow shape so the food can cool quickly. If packing soup, use the container as directed and leave room for expansion. Note the dish name, cooking date and any ingredient information someone else needs. Check that the container itself is suitable for any later reheating method.

Thaw without leaving food on the counter
Move a portion to the fridge in advance. If you use the microwave to thaw it, follow the appliance directions and reheat it immediately. A product intended to be heated from frozen can have its own directions. Do not thaw ordinary perishable leftovers at room temperature. SFA’s guidelines on thawing food

Heat the portion thoroughly and serve
Reheat suitable leftovers once, checking the centre and other thick spots. Stir or rearrange the food when practical. For hot food, SFA’s guidance specifies at least 75°C internally for at least two minutes. Use a clean thermometer when checking. SFA’s reheating guidance

Freezer questions
Can I freeze food to make it safe again?
Freezing does not undo unsafe storage. Discard food if you cannot establish that it was handled safely.
Should I freeze a large pot as one batch?
Use smaller portions that cool more quickly and match the amount you will reheat.
Can I use the same routine for rice?
Follow rice-specific instructions because cooked rice needs prompt cooling and careful storage.
