Can You Freeze Leftovers?

Yes, you can freeze leftovers. Best quality within 2–3 months; it stays safe beyond that at a constant -18°C.
What freezing does to leftovers
Cooked dishes such as curry, chilli, soup and stew are among the best things to freeze: the sauce protects the food from freezer burn and flavours often improve. The FoodKeeper window for leftovers containing meat, fish, poultry or egg is 2–3 months for best quality; it stays safe beyond that. FoodKeeper gives leftovers a best-quality freezer window of 2–3 months. For comparison, the same database gives plain cooked chicken 4 months, cooked pasta 1–2 months, cooked rice 1 month.

Common questions
How long can you freeze leftovers?
For best quality, up to 2–3 months (USDA FoodKeeper). It stays safe beyond that, because bacteria cannot grow at a constant -18°C; the time limit is about taste and texture, not safety. Label the pack with the date so you can use the oldest first.
How should I freeze leftovers?
Cool it fast (spread it in shallow containers, within an hour or two), then freeze in portion-sized containers or flat bags. Leave a gap at the top for expansion in liquids, and label with the dish and date.
How do I defrost leftovers?
In the fridge overnight, or in the microwave on the defrost setting if you will eat it straight away. Reheat once until piping hot throughout (75°C); bring soups and sauces to a full simmer.
Can you refreeze leftovers?
Not once defrosted, other than by cooking it into a new dish first. Freeze in portions so you only reheat what you will eat.
Fridge or freezer for leftovers?
The fridge window for leftovers 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 leftovers 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.
