If you want to make homemade sauerkraut, you’re in the right place. All you need is cabbage, salt, and some clean tools to get started. Oh, and you’ll also need some patience. In most cases, your fermented veggies won’t be ready to eat for at least 2 weeks.
I originally shared this recipe in 2012, when I was very nervous about home fermentation. If you’re like me, you might be worried about knowing if it’s safe to eat. I’ll cover some things to look (and smell) for later in this post!
I think it’s also important to mention that you don’t need a fermentation crock to make this. When I started, I used a glass jar and a plastic bag filled with salt water as the “weight” to keep the cabbage submerged. So, I’ll let you know how to do that, but I also tested this with a fermentation crock to see if it’s any easier. I’ll share more on this below!

“Thank you so much for sharing this post. I had been wanting to give this a try for a while and your post gave me the nudge (and confidence) that i needed to do it! I must say I was more than pleased with the results and am currently obsessed! I MUST have some every day now!! Thank you, thank you!” – Colleen
Ingredients You’ll Need
- Cabbage. I usually work with one head of cabbage at a time, and mine tend to be about 2.5 pounds when I buy them from the store. By the time you remove the core and outer leaves, I have 2 pounds of cabbage to work with, give or take.
- Salt. I use fine pink salt (Real Salt brand) for this recipe, so keep in mind that white table salt will make this taste even saltier.
Note: You might also need to make a 2% salt water solution to keep the cabbage fully submerged. To make this, use 1 teaspoon of salt for every 1 cup of water. Boil these together until dissolved, then cool completely before pouring over the cabbage.
How to Make Raw Sauerkraut
Step 1:
You’ll want to start with really clean tools. Sanitize your jar, knife, cutting board, tongs, and glass bowl with boiling water to kill any bacteria. I usually just wash them in the dishwasher before getting started.
Remove any dirty outer leaves from a head of cabbage. Then remove one or two more and save them for later. Then use a sharp knife to slice away the hard core and finely shred the cabbage. The thinner you slice it, the better. (Thinner cabbage will soften faster.)
Transfer the cabbage to a large bowl and season it with 2 tablespoons of salt. Let it rest in the bowl for 15 minutes, so the cabbage starts to sweat. Then massage it with your hands for about 5 minutes. It should release even more liquid as you massage it. This will be your brine!
Note: This recipe assumes you’re using approximately 2 pounds of cabbage, after slicing away the core and discarding dirty outer leaves. If your cabbage head is significantly larger than that, you might want to use a little more salt. Usually, you’ll use 1 tablespoon of salt per pound of cabbage.
Step 2:
Use your hands to transfer handfuls of the salted cabbage to a clean jar. One pound of wilted cabbage will usually fill a 32-ounce mason jar when packed tightly. Or, you can use a fermentation crock if you have one! (I bought this one from Amazon, and it’s pretty large if you’re only fermenting one head of cabbage; it only fills the jar halfway.)
If you’re not sure whether you’ll ferment veggies regularly, start with a glass mason jar.

I'll email this post to you, so you can come back to it later!
Make sure you pack the cabbage tightly into the jar; use your clean hand to push it down as much as possible. It’s ideal if you see no air bubbles. Pour the remaining liquid from the bowl into the jar. It should cover the cabbage fully.
Remember that cabbage leaf you reserved earlier? Cut it into a rough circle that fits in your mason jar. Place it on top of the cabbage, and press down so the brine liquid covers this leaf, too. The goal is to keep the cabbage fully submerged at all times.
To help with this, you’ll also want to use some sort of weight to press down the cabbage. You can buy glass weights specifically for this purpose. But when I was just getting started, I would fill a Ziploc bag with salt water (1 teaspoon of salt dissolved in 1 cup of water) and place it on top of that cabbage leaf. Either method works!
Note: The reason you fill the Ziploc bag with salt water is that, in the off chance the bag breaks or leaks, your cabbage would still be safely submerged in a salty solution. Don’t use chlorinated water for this, as it can stop fermentation. It’s best to use spring water or filtered water.
Step 3:
Once you’ve fully submerged the cabbage, there’s only one thing left to do: wait. Add a loosely fitting lid to the jar so carbon dioxide gas can escape during fermentation. Fermentation crocks have a release nook built into the lid, but you can also just cover your mason jar with cheesecloth and a rubber band. This will let gas escape and keep dust out.
When I first made this, I screwed a plastic lid on the jar, and it was fine. But, I’ve also heard that fully sealing the jar can cause it to crack from pressure… so, it’s probably safer to not fully screw on the lid.
Also, if you don’t think you have enough brine to fully keep the cabbage submerged, cover the cabbage with a 2% salt water solution. That means, dissolve 1 teaspoon of salt into 1 cup of water (or double this if needed). Let the solution cool, then pour it over the cabbage.
It will take at least 2 weeks to ferment, so check the jar intermittently to make sure the cabbage stays submerged. When I made this in a fermentation crock, it was too dark to see anything, so I just had to trust the process. It still worked out well!
Serving and Storage Tips
Once the sauerkraut has fermented to your liking, remove the weight and the top cabbage leaf. Taste it to make sure you’re happy with the flavor. If you’re pleased, secure a lid on the jar and store it in the fridge. Keeping it chilled will slow down the fermentation process, but it will still continue to ferment slightly.
Enjoy it over the next 3 to 6 months, and always use a clean fork when removing it from the jar. (And keep the cabbage as submerged as possible, so it won’t mold.)
How To Make Raw Sauerkraut
Ingredients
- 1 head green or purple cabbage
- 2 tablespoons sea salt
Instructions
- Start with really clean tools. Sanitize your jar, knife, cutting board, tongs and glass bowl with boiling water, which should kill off any lurking bad bacteria. We only want the good kind growing in our veggies!
- Rinse cabbage well, and remove the large outer leaves. (You’ll want to save these for later.)
- Using a sharp knife, shred the cabbage and transfer it to a large glass bowl. Add about 2 Tablespoons of salt, then, using tongs or clean hands, massage the cabbage until it starts to break down from the salt. It will release moisture and reduce in size.
- Transfer the massaged cabbage to a clean glass jar, preferably one that is large enough to fit your hand through the top. The most important part of making fermented veggies is that you remove all the air in the jar– so you want to pack the cabbage tightly, leaving no gaps! I used my fist to punch it down, but a clean wooden spoon would work, too.
- While there is already plenty of moisture released from the cabbage to make the brine, I like to add a little salt water solution to make sure the liquid level is completely ABOVE the shredded cabbage. (Do not use tap water; see the ingredient notes in this post if you need to cover it with a 2% salt water solution.)
- Once you’ve added the water, use the reserved cabbage leaves to press down the shredded cabbage– keeping it submerged under the liquid.
- Ideally, you’d fill up the jar all the way to the top, but mine didn’t work out that way. If that’s the case for you, too, simply fill a plastic bag with salt water (in case it bursts in the jar, you want it to be salt water!) to use as a “weight.” Place the salt water bag on top of the large cabbage leaf layer, and seal the jar. You should be able to see the liquid layer above the shredded cabbage line.
- Cover the sealed jar loosely with a lid, so gas can escape, or with cheese cloth and a rubber band. Let it ferment for 2 weeks and check on it occasionally to make sure the cabbage it still fully submerged.
- Once the sauerkraut has fermented to your liking, remove the weight and outer leaves and discard. Note: It’s not uncommon for a layer of mold to develop on the outer leaves. This doesn’t mean your sauerkraut is ruined! Simply discard the layer of mold, and everything underneath the brine should be safe. As always, use your best judgement– if it smells off, don’t eat it.
- Store in the fridge and enjoy! The sauerkraut will last for months in the fridge, so feel free to make a BIG batch!
Notes
Nutrition
I’ve pickled cucumbers but haven’t tried cabbage. Can I used bagged shredded cabbage instead?
I always thought it was difficult to make homemade saurkraut. I never thought it could be so simple. I’m making some today.
Why do you need to put the jar in an insulated bag? Isn’t being in the refrigerator enough?
I believe you refrigerate after the fermentation process is done. I think what she is saying is that you put it in the insulated bag to keep the temperature regulated in case your home is too warm or too cold.
Super easy to make!
Loved the clarity & simplicity of the description. Very easy to follow recepie. Thank you for the lovely recepie. I felt motivated & positive to make this item. I understood the method & tips so well as you explained everything beautifully & clearly. Thank you very much! 🌷
