How long does onion powder last in the pantry?
Onion powder runs 3–4 years in the pantry, but it pulls water out of the air, so the jar usually cakes solid long before the flavour has gone.

Can it sit out?
Onion powder is shelf-stable, so sitting out at room temperature isn’t the safety question — storage time is.
How to tell if onion powder has gone bad
- A brick of powder that won’t shake out at all
- A flat, cardboard smell rather than sweet onion
- Powder darkened to caramel brown in the jar
- Damp on the underside of the lid
When in doubt, throw it out.
A few grains of rice in the jar keep it pouring — onion powder takes on humidity faster than almost anything else on the spice shelf.
