Frequently Asked Questions
How long does mayonnaise last in the fridge?
Mayonnaise usually last 2-6 months (opened 2 months; unopened 3–6 months) when stored correctly. Treat that as a quality window, then use smell, texture, and visible spoilage checks before eating.
Can you freeze mayonnaise?
Yes. The usual freezer window is 2-3 months (not recommended; texture separates). Freeze in airtight portions, label the date, and thaw in the fridge for the best safety and texture.
How long can mayonnaise sit out?
Use 1-2 hours as the room-temperature limit. When in doubt, refrigerate sooner; warm counter time is where most safety margin disappears.
