How to thaw cashews
In the fridge

At room temperature
Only for shelf-stable foods; perishable food should not thaw on the counter.
From frozen
Many foods go straight into soups, sauces, smoothies or the oven.
Cashews left out overnight
Cashews are shelf-stable. A night on the counter is fine — keep them cool, dry and away from sunlight.
Best-by and use-by dates on cashews
Best-by and sell-by
FoodKeeper gives unopened cashews 2–4 weeks in the pantry or 6 months in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Past the date
Cashews past their best-by date are usually safe if stored well; check smell, look and taste before using.
How to store cashews
- Keep in a cool, dark place, tightly closed, away from heat.
- Refrigerating nuts, seeds and nut oils extends shelf life significantly.
- Smell before using; rancidity is a quality problem you can detect.
