How long does bottled salad dressing last in the fridge?
Bottled dressing runs 1–3 months in the fridge after opening — a wide range because the ingredients are, so count dairy-based bottles short and plain oil-and-vinegar long.
How long does it keep?
| Pantry, from purchase | 10–12 months |
|---|---|
| Fridge, opened | 1–3 months |
Can it sit out?
Unopened, bottled salad dressing is shelf-stable. Once opened, treat it as 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 bottled salad dressing has gone bad
- An oily film round the neck that smells like old walnuts
- Strands or chunks in a dressing that used to pour smooth
- Muddy, faded color held up against a fresh bottle
When in doubt, throw it out.
Bottles live better on a middle shelf than in the door, where every opening warms them and cools them again.
