How long does ketchup last in the cupboard?
Ketchup
Opening never extends a date: if the packet date comes sooner, go by that. Estimates for quality, not a safety ruling. What the dates mean
Ketchup keeps for about 6 months in the cupboard, counted from when you buy it. That's SnapLarder's estimate for ketchup in general. If the packet has a date, go by the packet: it's specific to that product.
How long does ketchup last once opened?
About 8 weeks. Opening never extends a date: if the date on the packet comes sooner, go by that. Check the label, too: some products need to go in the fridge once opened.
Does ketchup have a use-by date?
Usually not. Ketchup normally carries a best-before date, which is about quality rather than safety. Stored as the label says, it’s usually still safe after it, though it may not be at its best. Use by vs best before
Can you freeze ketchup?
There's no need. Ketchup already keeps for about 6 months in the cupboard.
