How Long Can Ketchup Sit Out?
It depends on how much you use ketchup – if you use it frequently then let it sit out as its shelf life is that of one month if kept at room temperature. However, if you want to retain it for longer, then store it in a refrigerator to prevent it from going bad.
Ketchup is an acidic, concentrated product, so you do not have to keep it refrigerated, and generally can leave it outside for up to one month before it starts turning rancid.

Ketchup can be stored unrefrigerated for up to a month, but if you do not think you will use up your bottle within this time frame, you are better off keeping it in the refrigerator.

If you do not use your ketchup that frequently, every bottle stays open at least a couple months, if not longer.
