Can it sit out?
Unopened, creamy 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 creamy salad dressing has gone bad
- Separation that won’t come back together no matter how hard you shake
- A sour, turned-buttermilk smell at the cap
- A darkened, gluey ring inside the neck
When in doubt, throw it out.
Ranch and blue cheese thin out as they sit — a dressing that pours like milk has lost the cling that made it worth using.
