The short answer
Salad Dressing lasts as long as you store it correctly — which can mean anywhere from a few days on the counter to a year in the freezer. The numbers above represent best quality per USDA and FDA guidelines, not absolute safety limits.
Why these numbers vary
Bottled dressings. Storage life depends on temperature consistency, humidity, packaging, and how fresh it was when you got it. Refrigerators that swing between 38°F and 45°F shave days off these numbers; vacuum-sealing or freezing extends them.
How to tell if salad dressing is bad
- Separation (oil-based: shake; creamy: toss if thick clumps)
- Mold
- Sour smell
Storage tips
- Creamy dressings spoil faster than oil/vinegar
- Refrigerate after opening always
