Can Sauerkraut Be Frozen?
If you're wondering, “Can you freeze sauerkraut?” the answer is yes, you can. However, there are some things you may want to consider before stocking up the freezer. Both homemade and store-bought sauerkraut can technically be frozen, and doing so can extend its shelf life. That said, if you freeze sauerkraut, it will affect the texture and probiotic content that this fermented cabbage is known for.
With homemade sauerkraut, freezing can be a convenient option if you have a huge batch and aren’t able to finish it within a month or two. Store-bought sauerkraut is generally more stable due to packaging and pasteurization, but freezing it can still be an option if you want to extend its freshness beyond the expiration date.
Depending on your main reason for eating this pickled treat, keep in mind that though you can freeze sauerkraut, it may cause some of the beneficial probiotics to die off. So can you freeze sauerkraut? If you’re looking to retain the health benefits, then it's best to store your sauerkraut in the fridge.
Does Freezing Sauerkraut Kill Probiotics?
When people ask, "Can you freeze sauerkraut?" they often overlook one important factor — the probiotics. Freezing sauerkraut will destroy some of those good bacteria that help promote digestive health, heart health and boost the immune system.
This fermented cabbage dish contains several beneficial probiotics that are vital for breaking down food and making nutrients easier to absorb in your body. These live bacteria also improve mood and keep your digestive system in check.
However, when you freeze sauerkraut, the extreme temperature can damage some of these probiotics. So, can you freeze sauerkraut without diminishing its probiotic benefits? While freezing won't spoil the sauerkraut completely, it locks away and even kills some of its health-promoting bacteria. This ultimately reduces the health benefits. It's best to store sauerkraut in the fridge, where the probiotics can stay alive and active for months.
Can You Freeze Cooked Sauerkraut?
You might be asking yourself questions like, "Can you freeze cooked sauerkraut?" The answer is simple. Yes, you can, but there’s a big caveat. When you freeze sauerkraut that’s been cooked, it once again strips away its probiotic properties, leaving you with a tart cabbage dish that's still tasty but without the gut-health perks.
If you want to retain its probiotic goodness, it’s suggested not to cook sauerkraut in the first place. Heat destroys the beneficial live bacteria that support digestion and boost immune function. Of course, if you have leftovers, you can sauerkraut to avoid waste, and it’s always better to freeze leftover food than waste it.
You can store it in the freezer for up to six months, though freezing may slightly affect its texture and flavor. Just make sure to use a freezer-safe bag or container to prevent freezer burn. So, can you freeze cooked sauerkraut? The choice is yours, as long as you're aware of the potential limitations to health benefits, flavor and texture before you go ahead.
How To Store Sauerkraut
Can you freeze sauerkraut in a way that doesn’t kill off its probiotics? Unfortunately, not really. It’s better to store this tangy cabbage dish properly to extend its shelf life and maintain its tang and crunch. There are many ways to store it so you can enjoy it for months or even years without trying to freeze sauerkraut.
In a can
Canning is a popular method, where the cabbage is sealed in an airtight tin. If you’re still wondering, “Can you freeze sauerkraut?” and want to know which method is better, know that canning preserves the sauerkraut for up to three years when stored in a cool, dark place. Canning, like freezing, may reduce some probiotic content, however, it offers a longer shelf life and helps prevent rot and contamination, making it a reliable option for long-term storage.
In the fridge
For those with extra room in the fridge, refrigeration is the best way to store your fermented cabbage. Consider that refrigeration keeps it fresh for up to six months while preserving its probiotics.
This is because the cool temperature allows the cabbage to ferment slowly, maintaining its gut-health benefits in a way that wouldn’t if you decided to freeze sauerkraut. A fridge running at around 35 to 40 degrees Fahrenheit slows down the living probiotic organisms nearly to a halt, ensuring optimal preservation.
In the basement
If you don’t have freezer or refrigerator space, can you freeze sauerkraut in a cool basement instead? This is a good alternative solution. Most cellars hover around 55 degrees Fahrenheit, which is good for keeping sauerkraut for about a year, though it may soften slightly over time. Just be sure to check the temperature, as climates can vary, affecting how well your sauerkraut stays fresh.
In a Korean kimchi pot
How was this fermented dish traditionally preserved before refrigerators and freezers, and can you freeze sauerkraut using the same methods? One storage idea is to use a traditional Korean kimchi pot, also known as Onggi. These pots allow sauerkraut to breathe while keeping harmful bacteria out. The oxygen inside helps with fermentation and enhances the flavor.
You can store sauerkraut in an Onggi for up to two months. However, once opened, it should be used within a week. This makes Onggi a great short-term solution to preserve sauerkraut's quality.
While it’s best not to freeze sauerkraut, you may be surprised to learn that this fermented cabbage dish is resilient. It can actually survive at room temperature, thanks to its acidic nature. Both store-bought and homemade sauerkraut can be kept on the kitchen counter. Store-bought sauerkraut will last about a week once opened, while homemade sauerkraut can stay fresh for up to two weeks at room temperature.
How Long Can You Freeze Sauerkraut?
So, how long can you freeze sauerkraut? If you must, you can store it in the freezer between eight months to a year before it starts to lose its flavor and texture. Freezing won’t necessarily make it spoil, but as well as reducing its health benefits, it can alter the taste and texture — two key elements that make it so enjoyable.
Here are some tips if you do choose to freeze sauerkraut:
- Make sure to use heavy-duty plastic bags or freezer-safe plastic containers.
- Be sure to leave space at the top of the container, as the liquid in sauerkraut expands when frozen.
- Try to squeeze out as much air as possible if you’re using a plastic bag, and make sure your containers are sealed tightly.
Keep in mind that while freezing extends its shelf life, you’ll likely lose most of the probiotic benefits when thawed. If you’d like to preserve the best flavor, make sure to thaw slowly in the fridge.
Can You Freeze Sauerkraut in a Bag?
So, you can freeze sauerkraut, but can you freeze it in a bag? The answer is yes. Storing it inside a bag is a great way to keep it fresh for later consumption. However, make sure you're using freezer-safe plastic bags since they're made to withstand the cold temperatures of the freezer. Plus, these bags help prevent freezer burn and maintain the sauerkraut's flavor and texture as much as possible.
When freezing sauerkraut in a bag, remember:
- It's important to remove as much air as possible before sealing. This helps preserve the quality of the fermented cabbage and lowers the risk of freezer burn.
- Make sure to leave about three inches of space at the top of the bag since the sauerkraut can expand as it freezes.
- For added protection, you can place the sealed bags inside plastic containers to avoid any potential leaks.
- Properly stored, bagged sauerkraut can be kept in the freezer for up to 12 months.
