How to Store Pistachios. If your pistachio trees have produced a bumper crop this year, or if you're fortunate enough to have an abundance of pistachios, you're in luck. When properly prepared, pistachios are great keepers. Take the time to store the pistachios correctly and you'll have plenty for all those delicious pistachio recipes or just to snack on.

Choose pistachios that are open at one end. Unsplit pistachios are immature and won't taste good or store well.

Place the unshelled pistachios in a sturdy, airtight container and store them in the refrigerator, or in a dark, cool, well-ventilated place for up to three months. Unshelled pistachios will keep in the freezer for up to a year. The cooler the temperature, the longer the pistachios will last.

Put shelled pistachios in an airtight container and keep them in the refrigerator for up to three months. Shelled pistachios don't freeze well.

Know that if your freezer is very cold, (0 degrees,) pistachios can be stored up to three years.


  • If stored pistachio nuts have lost their crispiness, place them in a single layer on a baking sheet and toast them for about 10 to 15 minutes at 200 degrees. Allow the pistachios to cool before you eat them. When you thaw frozen pistachio nuts, place them in a plastic bag to prevent the formation of condensation. Pistachios shells are naturally a light tan or off-white color, and the ripe nuts are green. Bright pink and red pistachios have been artificially colored.
