People use ranch dressing with everything, from pizza and wings to chicken fingers. An open bottle of ranch dressing is a staple in many fridges, but how long does it keep?

While USDA says that ranch dressing stays good for two months in the fridge, some push that span to six to nine months. That said, store-bought dressing lasts longer than homemade.

Ranch is best refrigerated in the back of a lower shelf, where it's coldest. Keeping it in your fridge’s door exposes it to temperature fluctuations every time you open the fridge.
