🫙 How long does opened mayonnaise last?
Guideline times for a product stored properly, with the fridge at 4 °C or below.
| Where | How long |
|---|---|
| In the cupboard, unopened | until the date on the label |
| Once opened (in the fridge) | until the date on the label |
| In the freezer | not recommended |
To make it last longer
- Once opened it goes in the fridge: the jar usually says how soon to finish it. Note the date.
- Always use a clean spoon, never one that has touched other food.
- Homemade mayonnaise, made with raw eggs, must be kept in the fridge and eaten the same day.
When to throw it away
Oil separating, dark yellow colour, sour or rancid smell or taste, mould.
These are general guidelines and don't replace what's written on the pack: if the label says something different, follow the label. "Use by" is a real expiry date; "best before" is about quality. If in doubt, don't eat it. The difference between the two dates →
