How Long Does Cashew Butter Last?
Storage tips and freshness cues for your favorite nut butter.
Cashew butter stays fresh in a pantry for 6–9 months.
Cashew butter offers a creamy, buttery texture that makes it a versatile staple for spreading on toast or blending into smoothies. Because of its high oil content from the nuts, maintaining proper storage is key to preventing rancidity. When kept in a cool, dry spot away from direct sunlight, cashew butter retains its flavor and smooth consistency for several months. However, once opened, exposure to air can accelerate the oxidation process. Monitoring for changes in aroma or texture helps you determine when it's time for a fresh jar.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
