Expiration & Storage Tips
When does chicken stock expire?
Chicken stock is best stored in the refrigerator where it should be used within a week. If you made it homemade or bought it from a fresh deli counter, then 3-4 days is a safer estimate. Store-bought varieties may last a bit longer, depending on the preservatives used, but I generally recommend treating it the same way as homemade. In comparison, if it's left unopened, store-bought varieties of chicken stock often last a few months past the sell-by date printed on the package, but always check the best before or use by dates to play safe. For longer storage, chicken stock can be frozen for up to 6 months.
How do you tell if chicken stock is bad?
You can tell if chicken stock has gone bad if it has a sour or rancid aroma, or if it begins to develop a cloudy appearance. These are signs of bacterial growth which is a no-no. Check for mould – if you see green or black spots, get rid of it straight away. If the stock stays slimy even after boiling, it's likely gone bad. You should also always use your own judgement – if you're in doubt, it may be safer to just throw it out!
Tips for storing chicken stock to extend shelf life
• Always cool chicken stock quickly after use and transfer it to the refrigerator within two hours.
• Divide large batches of chicken stock into smaller portions for quick cooling and easy use.
• Use airtight containers or heavy-duty freezer bags if you intend to freeze the stock.
• Label containers with the storage date to prevent using the stock beyond its safe window.
• Keep the refrigerator temperature below 5°C (41°F) to maximize the shelf life.
• Instead of reheating the whole container, only take out as much stock as you need, so it doesn't go through multiple heating and cooling cycles (which can encourage bacteria growth).
