How Long Do Cooked Prawns Last in the Fridge?
Written by Jordan Morley · Storage times from FSA and NHS guidance (fridge limit) and the USDA FoodKeeper database (freezer and cupboard) · Last updated 28 October 2026
Cooked Prawns keep up to 2 days in a fridge running at 0–5°C.
Storage tips for cooked prawns
- 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.

Common questions
How long do cooked prawns 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 prawns have gone off?
A strong fishy or ammonia smell, a slimy surface, dull flesh or milky liquid in the pack are all reasons to bin it. Do not rely on this alone: the time guideline matters even when everything looks fine.
Can I freeze cooked prawns to keep them longer?
Yes. For best quality, freeze them for around 1–3 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.
