How long does homemade vinaigrette last in the fridge?
Homemade vinaigrette keeps 2–3 weeks in the fridge — it’s the fresh garlic and herbs setting that ceiling, not the vinegar.

Can it sit out?
Homemade vinaigrette is perishable — the FSIS 2-hour rule applies.
Perishable food left at room temperature for more than 2 hours should be thrown out — 1 hour if it’s 90°F or hotter (a picnic, a hot car, a summer kitchen).
How to tell if homemade vinaigrette has gone bad
- Garlic or herb bits gone slimy in the bottom of the jar
- A stale, nutty-rancid smell off the oil
- Pressure or a fizz when the lid comes off
When in doubt, throw it out.
Whisk the mustard in first — an emulsion that holds keeps the aromatics suspended instead of settling into sludge at the bottom.
