Freezing Unshelled Walnuts

Portion Them

Divide the walnuts into portions you can easily consume in one go for easy thawing later on. 

Pack and Seal

Transfer the portioned walnuts into a freezer-safe air-tight container or Ziploc bag and seal them. If you are sealing a Ziploc bag, try to remove as much excess air as possible. You could use a straw to make this process easier. 

Label and Freeze

Freezing Shelled Walnuts

Time Taken: 10 – 15 minutes 

What you will need:

  • Baking Sheet

  • Cling Wrap
  • Freezer-Safe Air-Tight Container or Ziploc Bag 

If you have already shelled the walnuts, you could follow these simple steps to freeze and store them.

Spread and Cover

Evenly spread the walnuts onto a baking sheet lined with parchment paper. Cover the tray with cling wrap to avoid the walnuts from absorbing any odor. 

Flash Freeze

Leave the baking sheet in the freezer for a couple of hours or overnight and let the walnuts freeze solid. 

Pack and Seal

Transfer the frozen walnuts into a freezer-safe air-tight container or a Ziploc bag and seal them. When sealing a Ziploc bag, try to squeeze out all the excess air. 

Label and Freeze

Once you add a label with the date on the container or bag, you can leave them in the freezer. 

Freezing Toasted Walnuts

If you have toasted the walnuts and want to store them for long then this is a simple and hassle-free method to follow. 

Prep and Cool

Toast the walnuts till they brown, and then let them cool down to room temperature on a cooling rack. 

Pack and Seal

Transfer the cooled toasted walnuts into a freezer-safe air-tight container or Ziploc bag and seal them. Try and remove as much excess air as possible when sealing a Ziploc bag. 

Label and Freeze

Add a label with the content name and date, and you are all set to freeze the toasted walnuts. 

How Long Can You Freeze Walnuts? 

You can store walnuts in the freezer for a whole year if done right. As long as it is in an air-tight container and kept in the coolest part of the freezer, it should stay fresh for long.

The toasted walnuts can also last for 10-12 months in the freezer.

But keep in mind that unshelled walnuts will last longer than the shelled walnuts due to their protective covering. Shelled walnuts are more prone to getting rancid over time. 

How to Store Frozen Walnuts? 

You can store frozen walnuts in any freezer-safe air-tight container or Ziploc bag. If it is an unopened store-bought packet of walnuts, you can directly toss it in the freezer. 

Although a freezer-safe container would work just fine, a Ziploc bag is a much-preferred option.

Because most of us are pressed for freezer space, and a container would take up too much space. It would also be hard to pack too many unshelled walnuts into a container. 

So, the Ziploc bags are your best bet, and they can be laid down flat on top of the other and leave a lot of room in the freezer.

It is also great to pack the walnuts into small bags, and you can have their snacks on the go. 

How to Defrost Walnuts? 

The best way to defrost walnuts is to leave them in the fridge for a couple of hours or overnight and let them thaw gradually. 

If you plan to cook the walnuts, you can go ahead and use them directly without thawing them. You could also thaw them on the kitchen counter if you are in a hurry.

But keep in mind that if the walnuts have been exposed to air for too long, they can spoil easily due to their high-fat content. 

Can You Refreeze Walnuts? 

Yes, you can refreeze walnuts. But it would be best not to repeatedly freeze and thaw the walnuts, especially shelled walnuts since they can get rancid easily. 

If you have frozen unshelled walnuts or shelled walnuts that have been flash frozen, you can take out the portion you need and seal the rest back in rather than thawing the whole batch and refreezing the rest. 

You could also portion them beforehand into single-servings that you can easily manage in one go. 

Do Walnuts Freeze Well? 

Yes, walnuts freeze well and can last in the freezer for a whole year, as long as they are stored in air-tight containers. 

Unshelled walnuts freeze the best whereas shelled and roasted walnuts can get rancid over time.

If you plan to use ground walnuts, it would be best to ground them after they have been defrosted rather than freezing them in powder form. Ground walnuts can spoil much quicker than whole walnuts. 

FAQs

Can you freeze ground or crushed walnuts? 

No, it is best not to freeze ground or crushed walnuts as they can lose their flavor over time and can easily spoil when exposed to air. Instead, you could freeze walnuts as a whole and then process them after they are defrosted.
