Why Are My Roasted Pistachios Soft?

Soft pistachios aren't necessarily bad. They might have absorbed some moisture from the air if they were left in humid conditions. You can actually recover their crispy crunchiness by toasting them in your oven for about 10 minutes.

How do you fix soft pistachios?

Just toasting them in a dry pan or oven should be enough to revive them, but they'll also go in any recipe that requires nuts. We got through most of ours by toasting them with spices, to eat as nibbles or to add crunch to soups, stews and salads. I also made a vivid green marzipan with some of the pistachios.

How do you make pistachios crunchy again?

Last but not least, your pistachios might seem to be okay, but taste a bit stale and lose their crunch. If that's the case, shell them and toast at 200 degrees F (~90 C) for 10 to 15 minutes ([SBP]) to get some of that crispness back. Give them a few minutes before wolfing them down.
