Cashews are a very popular nut, but many people aren’t aware of how long they last. If you’re wondering how long cashews should last, it’s important to know that their shelf life is around 12 months or two years—and not much longer.

Cashews have a long shelf life when stored properly. However, the shelf life will vary based on temperature and humidity levels in the environment where you store your cashews. 

So the longer you store your cashews at room temperature or below 65 degrees Fahrenheit (18 C), the more likely they will lose some of their nutritional value. 

Because most vitamins and minerals are sensitive to heat and light, exposing them to these conditions means they won’t remain as potent for as long as they would if stored under cooler conditions.

The best way to keep your cashews fresh and retain their nutritional value is by storing them in an airtight container and keeping them from light sources (such as windows) or direct sunlight. You can also place them in a freezer if you keep them longer than a few months (which should not exceed six months). The best cashew storage times are between three months and one year, depending on how long you plan to keep them.

Remember, Cashews should be stored in an airtight container in a cool, dry place.

If you’re worried that your cashews aren’t as fresh as they used to be, you can test their quality by smelling them. If they smell rancid, toss them. Also, cashews can be stored at room temperature in an airtight container for up to two weeks. After two weeks, they should be refrigerated or frozen until you’re ready to eat them again.

However, the longer it’s stored, the more moisture will build up in the nuts—and there’s a limit to how long you can store them at that point. If you want to keep your raw cashews longer than this, it’s best to purchase them already shelled and roasted.

The best way to store raw cashews is in an airtight container, such as a mason jar or sealed plastic bag. If you purchase already shelled cashews, you’ll also want to place them in an airtight container. 

Store all nuts in the refrigerator if you plan on using them within 2-3 days. If they will be longer, leave them at room temperature and let them dry out before storing them properly.

How Long Do Cashews Last in the Fridge

There’s no exact number of days that cashews will stay in your fridge, but if you store them correctly, they’ll be good for at least 2 months. That’s because cashews are fairly dense and don’t absorb much moisture or flavors—so they keep their shape pretty well.

And if you buy in bulk, keep them in an airtight container or inside the refrigerator. Try to eat them within six months of purchasing them if possible. But, if you do not keep your refrigerator cold enough, they will spoil faster than regular nuts.

But if you’ve got some old cashews in your pantry, don’t panic. Just toss them into a glass jar with an airtight lid and put them in the fridge for 6 months before using them again.

Here’s how long they’ll last in the freezer:

  • 1 pound of cashews will last for about two years if kept at 0 degrees Fahrenheit (32 degrees Celsius).
  • 2 pounds will last for about 4 years if kept at 0 degrees Fahrenheit (32 degrees Celsius).
  • 3 pounds will last for about 6 years if kept at 0 degrees Fahrenheit (32 degrees Celsius).
  • 4 pounds will last for about 8 years if kept at 0 degrees Fahrenheit (32 degrees Celsius).

However, the best way to store cashews is to purchase them in their shell. It allows the nuts to be kept in their original shape while they freeze, preventing the possibility of melting when placed in the freezer.

How Long Do Cashews Last After Opening

Cashews last for a month after opening if stored properly. They lose their freshness and taste once you open your cashews and start eating them. They begin to turn brown and develop an unpleasant odor. That doesn’t mean they won’t still be edible—but they certainly aren’t as tasty as when fresh.

And If you’ve opened a bag of cashews and left them on the counter for a few days, they’ll be a little stale by the time you’re ready to eat them. But if you’ve kept them in an airtight container in your pantry, they should still taste fresh and nutty even after several weeks.

How Long Do Soaked Cashews Last

Soaking cashews for a long time will preserve their nutritional value, but it’s not recommended because the cashews will become soft and mushy.

If you want to ensure your cashews stay firm, you can soak them in water for at least 1 to 24 hours. The shelf life of soaked cashews is only about 6 months.

It is because soaked cashews have a lot of water in them, which means they can mold if not stored properly. If you’re storing them in the fridge, keep an eye on them and throw away any that show signs of molding or smell bad.

If you’re storing them in the freezer, it’s important to note that they’ll stay safe for longer than six months. To ensure maximum shelf life, keep your cashews frozen until you need them—then pop one into boiling water for about 15 minutes, and it will be good as new.

Can Cashews Go Bad

Cashews are a great source of protein and fiber. They’re also low in fat, which makes them a good choice for people with diabetes.

However, cashews do go bad over time. That’s because they’re made up of a seed (the cashew) and an outer shell (the hull).

The hull on cashews is what keeps the nut itself from spoiling. But if you leave it on too long, it can begin to decay—and that’s when you might find yourself with moldy cashews!

If you notice any unusual odor around your nuts, discard them immediately. If you don’t have the time or energy to throw them out before they’ve gone bad enough to make you sick, put them in a sealed bag and store them in the freezer for up to 4 months.

But if you buy your nuts in bulk from a wholesaler or retailer with storage systems in place, then you won’t have this problem.

Furthermore, it’s important to check the expiration date on your cashews. If they’re past their expiration date, they’re probably going bad—and you’ll want to avoid eating them. The best way to tell if they’ve gone bad is by checking the color of your cashews.

 If they’ve turned an odd shade of grey, brown, or black, it’s probably time to toss them! If you don’t notice the change immediately, keep checking at least every month or two until you do.

Why Are My Cashews Soft

Why Are My Cashews Soft

Your cashews are soft because they have begun to dry out. You’ll notice that your cashews will lose their shape over time, even though you haven’t opened the bag for a long time. When this happens, your cashews will feel like cardboard and become unpleasantly crunchy when eaten.

So instead of throwing them out immediately, let them dry for a few days and then store them somewhere else until they’ve dried completely.
