How to tell if quiche is bad
Smell
Musty, sour or alcoholic smell.
Texture
Hard and dry is stale but safe; damp or sticky is not.
Colour
Discoloured spots on the crust or crumb.
Mould
Any visible mould — discard the whole item; roots spread unseen.
Quiche past the expiration date
Unopened
FoodKeeper gives unopened quiche 2 hours in the pantry, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Opened
Once opened, the printed date no longer applies. Count 3–5 days in the fridge from the day you open it.
How to keep quiche fresh longer
- Keep at room temperature in a bread box or sealed bag for the best texture.
- Refrigeration slows mould but makes bread stale faster.
- Freeze what you will not eat in time.
