Sauerkraut, a tangy and flavorful fermented cabbage dish, has been enjoyed for centuries as a staple in many cuisines. Whether you’ve made a large batch or have some leftovers, you may be wondering if it’s possible to freeze sauerkraut to extend its shelf life. In this article, we will explore the ins and outs of freezing sauerkraut and provide you with some helpful tips to ensure its quality and taste are preserved.

Can You Freeze Sauerkraut?

The short answer is yes, you can freeze sauerkraut. Freezing sauerkraut is a convenient way to store it for a longer period, especially if you have a surplus or want to preserve its flavor and texture. However, it’s important to note that freezing sauerkraut may alter its texture slightly, but it will still retain its distinct taste.

How to Freeze Sauerkraut

Here’s a step-by-step guide on how to freeze sauerkraut:

  1. Start by preparing your sauerkraut for freezing. If you have homemade sauerkraut, make sure it’s fully fermented before freezing.
  2. Divide the sauerkraut into portion sizes that you would typically use in a single meal. This will make it easier to thaw and use later.
  3. Place each portion of sauerkraut into a freezer-safe container or airtight freezer bag. Make sure to remove as much air as possible from the container or bag before sealing it.
  4. Label each container or bag with the date of freezing to keep track of its freshness.
  5. Store the sauerkraut in the freezer, ensuring it is kept at a consistent temperature of 0°F (-18°C) or below.

Thawing and Using Frozen Sauerkraut

When you’re ready to use your frozen sauerkraut, follow these steps:

  1. Remove the desired portion of sauerkraut from the freezer and place it in the refrigerator to thaw. Thawing sauerkraut slowly in the refrigerator helps maintain its texture and flavor.
  2. Once thawed, you can use the sauerkraut in your favorite recipes, such as sausages, sandwiches, or as a flavorful topping for hot dogs.
  3. Remember to use the thawed sauerkraut within a few days and avoid refreezing it to maintain its quality.

Tips for Freezing Sauerkraut

Here are some additional tips to ensure the best results when freezing sauerkraut:

  • Use high-quality freezer-safe containers or airtight freezer bags to prevent freezer burn and maintain the freshness of the sauerkraut.
  • Remove as much air as possible from the containers or bags before sealing them to prevent freezer burn.
  • Consider blanching the sauerkraut before freezing to help preserve its texture. Blanching involves briefly immersing the sauerkraut in boiling water and then cooling it in an ice bath before freezing.
  • Label each container or bag with the date of freezing to ensure you use the oldest sauerkraut first.
  • Thaw sauerkraut in the refrigerator rather than at room temperature to maintain its quality.


Freezing sauerkraut is a great way to extend its shelf life and ensure you always have this delicious fermented delight on hand. By following the proper steps and tips outlined in this article, you can freeze sauerkraut without compromising its taste and quality. So go ahead and stock up on sauerkraut, knowing that you can enjoy its tangy goodness even months down the line.
