How to Freeze Sauerkraut Properly
Freezing sauerkraut involves a few steps to ensure the best results. Here’s how to freeze it without compromising the quality:
Step 1: Use the Right Container
Airtight containers or freezer bags are the best options for freezing sauerkraut. Before placing the kraut in the container, ensure that it’s completely cooled and drained of excess liquid. Sauerkraut holds a lot of water, which can expand when frozen, so draining it helps prevent freezer burn.
Step 2: Remove Excess Air
When using freezer bags, make sure to remove as much air as possible to avoid ice crystals forming, which can affect the texture. For optimal results, spread the sauerkraut in a single layer in the freezer bags, flattening them to remove air. This step also makes it easier to thaw in portions.
Can You Freeze Sauerkraut After Opening?
Yes, you can freeze sauerkraut after opening it, and the process is the same. Be sure to transfer it to a freezer-safe container or bag if it’s in a glass jar. Once opened, the shelf life of sauerkraut in the fridge is limited, so freezing is a great way to avoid spoilage and extend its life.
Freezing after opening doesn’t impact the flavor or nutritional benefits, but like all fermented foods, the texture may change slightly after freezing. It will still be delicious when thawed, perfect for cooked dishes like borscht or as a tangy topping.
How Long Can You Freeze Sauerkraut?
Sauerkraut can be frozen for up to 8-12 months, maintaining much of its original flavor and nutritional profile. However, the longer it stays frozen, the more the texture may degrade. To ensure the best quality, try to use frozen sauerkraut within six months.
Always check for obvious signs of spoilage after thawing, like an off smell, color changes, or mold growth. While freezing generally halts bacterial growth, it’s important to inspect your kraut for spoilage before consuming it.
Can You Freeze Sauerkraut After It’s Been Cooked?
Yes, you can freeze sauerkraut after it’s been cooked, especially if it’s part of a larger dish like a stew or casserole. Cooked sauerkraut tends to freeze well because the heat breaks down some of the cell walls, reducing the risk of a mushy texture after thawing.
When freezing cooked sauerkraut, be sure to let it cool completely before packing it into freezer bags or containers. Label it with the date, so you know how long it’s been in the freezer. Cooked sauerkraut dishes, like sauerkraut soup or borscht, can last up to 3 months in the freezer.

What to Expect When Thawing Sauerkraut
Thawed sauerkraut can have a slightly different texture compared to fresh, but it’s still packed with flavor and probiotics. The kraut might be a little softer, especially if it’s been frozen for an extended period. Thawing can be done in the fridge over a few hours or quickly in cold water if you’re short on time.
If you notice greenish specs or an off smell after thawing, it could be a sign of spoilage, and you should discard it. Otherwise, thawed sauerkraut is safe to use in cooked dishes, and the flavor remains tangy and sharp.
Tips for Freezing Sauerkraut Successfully
- Use airtight containers or freezer bags to avoid freezer burn.
- Flatten freezer bags to remove excess air and for easier storage.
- Label the containers with the date to keep track of the freezing time.
- Portion the sauerkraut before freezing for easier use later.
