How to Freeze Sauerkraut?

Prep Time: 10 minutes
Total Time: 10 minutes

Although sauerkraut has a pretty good shelf-life, freezing it is one of the best ways to store it, especially if you don't use it too often.


  • Sauerkraut


  • Freezer-Safe Air-Tight Container or Ziploc Bags


    1. Portion the Sauerkraut: Divide the sauerkraut into portions that you can easily consume at a time.

    2. Pack and Seal: Spoon in the portioned sauerkraut into a freezer-safe air-tight container or Ziploc bags. Then seal them. If you are using Ziploc bags, take extra care to squeeze out as much excess air as you can.

    3. Label and Freeze: Add a label on the container or Ziploc bag with the best-before date, and you are ready to freeze the sauerkraut.

Freezing Cooked Sauerkraut

Time Taken: 5 – 10 minutes

What you will need: 

  • Cooked Sauerkraut 
  • Freezer-Safe Air-Tight Containers or Ziploc Bags

You could also freeze cooked sauerkraut in this simple and hassle-free manner.

Cool and Portion

Make sure that the cooked sauerkraut is at room temperature before you freeze it. Divide the sauerkraut into easily manageable portions. 

Pack and Seal

Spoon in the cooked sauerkraut into a freezer-safe air-tight container or Ziploc bags and seal them. When using Ziploc bags, try to squeeze out the excess air before sealing them. 

Label and Freeze

Label the container or Ziploc bag with the date, and you are all set to freeze them. 

How Long Can You Freeze Sauerkraut? 

Sauerkraut can last in the freezer for 6 months, and if done right, can even last for 8-12 months.

Though it is unconventional, you can freeze sauerkraut for long without losing its texture or flavor. It tastes almost the same after it is frozen. 

But for best results in quality, it is advised to consume frozen sauerkraut within a month or so. This is because the good bacteria may be completely removed if it stays in the freezer for too long. 

Also, keep in mind that the sauerkraut freezes best and for longer if they have been fresh beforehand. If the sauerkraut is closer to its expiry date, it may not last long in the freezer. 

How to Store Frozen Sauerkraut? 

You can store frozen sauerkraut in a freezer-safe air-tight container or Ziploc bags. Since you are most likely freezing sauerkraut because you have excess, the best option would be using Ziploc bags.

The Ziploc bags are compact and take up less space in the freezer.

If you are storing sauerkraut in the jar it came in, ensure that it is freezer-safe and that it is not packed too tightly.

It would be best not to leave an unopened jar of sauerkraut in the freezer because if it has been pressure sealed, it can crack once it freezes, and the sauerkraut can leak out. 

How to Defrost Sauerkraut? 

The best way to defrost sauerkraut is to do it slowly. Hence, leave the portion you need in the fridge for a couple of hours. It would be best to leave it in the fridge overnight and let it thaw gradually. 

Although you can thaw it quicker, by leaving the container or Ziploc bag or sauerkraut in a bowl of cold water on the kitchen counter for a couple of hours, it is not recommended. 

If you opt for the faster method, then you will have to consume it immediately as the sauerkraut can spoil faster this way. 

If you are looking to use the sauerkraut for cooking, then you can skip the thawing process and use it directly in your recipes. 

Can You Refreeze Sauerkraut? 

No, it is best advised not to refreeze sauerkraut. This is because the water content in the cabbage can separate if it is repeatedly frozen and defrosted.

This can make the sauerkraut get soggy, lose its texture and flavor, and make it go bad faster. 

To avoid wasting sauerkraut once it thaws, you can portion them into easy-to-consume serving sizes before packing and freezing them. 

Does Sauerkraut Freeze Well? 

Yes, sauerkraut freezes well, and it can last long in the freezer without losing much of its texture or taste. But freezing sauerkraut can remove some of its pro-biotic value. 

This is because freezing the sauerkraut for too long can kill the good bacteria in them. So, it is best to consume the frozen sauerkraut within a 1-month mark. 

That being said, it is quite unconventional to freeze sauerkraut because it has quite a good shelf-life even without freezing it.  


Can you freeze sauerkraut in an opened can? 

No, you shouldn’t freeze sauerkraut in an opened can as it can spoil easily and get freezer burns. The best way to freeze sauerkraut is to transfer it into a freezer-safe air-tight container or Ziploc bag after you have portioned it. 

Can you freeze sauerkraut and pork? 

Yes, you can freeze sauerkraut cooked with pork. After making sure that the dish has cooled down to room temperature, you can portion it and spoon it into a freezer-safe air-tight container or Ziploc bag. Then you can label and freeze it. It is best to consume it within a month or so. 

Can you freeze sauerkraut soup? 

Yes, you can freeze sauerkraut soup. But it won’t last too long in the freezer and cannot be refrozen. So, the best option is to portion it out and freeze it for a maximum of one month. You can freeze it in any freezer-safe air-tight container or Ziploc bags.
