Properly stored, dried split peas will generally stay at best quality for about 2 to 3 years at normal room temperature, although they will usually remain safe to use after that. To maximize the shelf life of dried split peas, keep the package tightly closed at all times.

Can you use out of date split peas?

If there is a date on your peas, it is the manufacturer's recommendation for best quality - not safety. Because of this distinction, you may safely use peas to compliment your favorite meals even after the sell by date has lapsed.

Are old split peas bad for you?
