Did you find a packet of pistachio while cleaning your pantry that has crossed the expiration date? This article will tell you how long pistachios last so that you can determine whether they are safe for consumption.
Pistachios go bad if they are not stored in the right conditions, especially in warm and humid conditions. But they stay in good condition for 6 months or up to a year when stored in a cold and dry place such as a refrigerator, freezer, or room temperature.
Like other nuts, pistachios are high-fat products that turn bitter when stored in inappropriate conditions.

In this article, you will learn how long pistachios last and the indicators that tell the possible signs of spoilage. Let’s take a look at all this information to know the shelf life of pistachios.

Shelled pistachios last for 3 to 4 weeks at room temperature if stored in an airtight container and for six months when stored in the refrigerator. When frozen, they can last for up to a year.
On the other hand, unshelled pistachios last longer than shelled ones. Unshelled pistachios can last for up to six months in an airtight container at room temperature and up to a year in the refrigerator.
Their life is further extended if you freeze them. Unshelled pistachio can last for up to 2 years.
These are the general guidelines for pistachio storage and its shelf life. However, it should be noted that the actual shelf life of pistachios depends on the quality of the product and storage conditions.
Can You Freeze Pistachios?
Pistachios can be frozen to extend their shelf life. Freezing pistachios helps preserve their freshness, texture, and flavor. To freeze pistachios, follow these simple steps:
- Place the pistachios in a freezer-safe plastic bag or airtight container.
- Squeeze out as much air as possible and seal the container or bag tightly.
- Label the bag with the date of freezing. Place the packed pistachios in the freezer.
How To Tell If Pistachios Have Gone Bad Or Spoiled?
There are a few signs to look out for to determine if pistachios have gone bad or spoiled. Let’s take a look at them.
One of the foremost indicators of spoilage in food items is the change in their appearance. If pistachios appear discolored or have a dull or dark appearance, or you spot molds on them, it is a clear sign that they have gone bad. Additionally, if the shells are cracked or damaged, it may indicate that the pistachios are no longer fresh.
The smell is a great tell-tale sign to find out the health of pistachios. If the pistachios in your hand smell rancid, stale, or off, it means they have gone bad.
If the pistachios have a bitter or off-flavor, it is a sign that they have gone bad or have become stale.
If the pistachios have become soft, stale, or chewy, it may indicate that they are no longer fresh and have gone bad.
Can you eat expired pistachios?
As a general rule, eating expired or out-of-date food items is not recommended. The same holds true for eating pistachios that are past their expiration date. They can increase the risk of foodborne illness and can cause unpleasant digestive symptoms.
The expiration date on the package of pistachios is an indication of when the product is at its freshest and highest quality. Post that date, the quality of the pistachios may start to degrade. They may not taste as good as when they were fresh.
Additionally, the fats in the pistachios can start to oxidize, causing them to become rancid, which can make them taste unpleasant and cause digestive issues.
However, eating pistachio a month or two past their expiry date should not make a difference if there are no changes in appearance, texture, smell, or taste. If you notice any of these signs, it’s best to discard the pistachios.
Tips To Extend The Shelf Life Of Pistachios
- Store pistachios in an airtight container: Storing pistachios in an airtight container or resealable plastic bag prevents air and moisture from getting in. This helps to keep the pistachios fresh for longer periods.
- Storing in a cool, dry place: You can extend the shelf life of pistachio by storing them in a cool, dry place, away from direct sunlight or heat. Heat and moisture can cause the pistachios to spoil or become rancid.
- Don’t mix old and new pistachios: It is always best to keep old and new pistachios in a separate container, as mixing old with new pistachios can cause the new ones to spoil more quickly.
- Refrigerate or freeze pistachios: If you’re not planning to eat the pistachios right away, storing them in the refrigerator or freezer will help extend their shelf life even further.
- Roast or toast pistachios: Roasting or toasting pistachios is a good way to extend their shelf life. These methods help in removing excess moisture from pistachios that attracts the growth of bacteria and bugs.
