Raw sauerkraut is surprisingly easy to make and is WAY cheaper than buying the store-bought stuff. For a just a couple dollars, you’ll have more fresh sauerkraut than you’ll know what to do with!
Fermenting my own veggies has always terrified me, since I was convinced I’d probably do it wrong and wind up with botulism. But people have been eating fermented food for centuries, so it can’t be as scary as it sounds, right?
Right.
Plus, it’s loaded with friendly bacteria for your gut, which has been shown to improve digestion and the absorption of vitamins and minerals. So, eat your (fermented) veggies.

Homemade Raw Sauerkraut
Ingredients:
1 head green or purple cabbage
2 Tablespoons sea salt
Spring or distilled water, as needed
Tools:
Wood cutting board
Sharp knife
Glass jar
Large glass or metal bowl
Metal Tongs
Ziploc bag (if needed for added weight)
Directions:
(You’ll want to save these for later.)
Using a sharp knife, simply 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.
Step 3: Transfer to a jar.
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.
Step 4: Cover with water and reserved cabbage leaves.
Like I mentioned above, the key to properly fermented sauerkraut is making sure there is no air remaining in the shredded cabbage. While there is already plenty of moisture released from the cabbage to make the brine, I like to add a little extra spring water (do not use tap water!!) to make sure the liquid level is completely ABOVE the shredded cabbage.
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.
Step 5: Store in an insulated bag for 3-7 days.
If your house is a too warm or too cold, the insulated bag ensures that the fermentation process is kept at an even temperature. My sauerkraut took a full week to reach the classic “tangy” flavor this time around, but it may take less time in warmer climates. You can start checking on it after 3 days, just make sure the liquid level is high enough each time you re-seal the jar!
Once the sauerkraut has fermented to your liking, remove the weight and outer leaves and discard.
*I’ve heard that 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.
Step 6: Store in the fridge and enjoy!
I’ve had raw food teachers tell me that raw sauerkraut can last almost indefinitely in the fridge… but hopefully you’ll eat it all before you can test that theory. It will definitely last for months in the fridge, so feel free to make a BIG batch!
Once you’re comfortable making your own sauerkraut, feel free to get creative with the veggies you add to it! Ginger, beets, carrots, garlic, and lemon juice all make tasty additions.
Ingredients
- 1 head green or purple cabbage
- 2 Tablespoons sea salt
- Spring or distilled water , as needed
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.

Hi- I am struggling a bit with my sauerkraut…It has plenty of brine when I put it in the jar, but then the brine goes down below the cabbage- like it is being reabsorbed?? Have you heard of this?
Also doesn’t the ziplock back leach into the sauerkraut seeing it has salt and bacteria that can break down the plastic?
Thank for your help!!
Hi. Thanks for the recipe! It looks nice and easy. It’s Covid-19 time, and I can’t buy an insulated bag. Is it okay to do this without one? Also, I have some other kind of salt — a pink salt from Portugal. I don’t think it’s sea salt. Does that matter?
Your pictures really helped me follow along with the recipe, I’m very excited to see how it turns out in a few weeks! Thanks for sharing!
What type of
insulated bag did you use?
Mine was a zip-up cold/hot shopping bag that I bought from Trader Joe’s.
Thank you for this perfect recipe for raw sauerkraut. Just what I was looking for. What a lovely website.
Thank you Megan, This recipe was exactly what I have been searching for. One, I love sauerkraut and am wanting to add more fermented and raw foods to my vegetarian diet. Thank you for your light filled website!
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!
Great post! I learned so many great tips from it. I’ve made sauerkraut before, but I got a little discouraged; I think my salt content was too high, and it just didn’t taste very good or seemed to ferment right. I’ll definitely need to try making it again. I never even thought about putting the jar into an insulated bag- what a terrific idea!
You don’t need to be too precious with this- it’s peasant food. Ordinary kitchen hygiene is fine. Lacto-fermentation is an anaerobic process which is why you need to keep out the air. I use a rolling pin end to tamp it down and usually it releases enough juice without adding any extra water. I add tasty seeds like caraway or cumin which give it a warmth. Delicious, cheap and easy way to improve your gut health.
So what happens if you add a small amount of tap water? I had mine fermenting for. 5-6 days. The top leaves totally molded, so I removed them and wiped off the glass anywhere it touched. The water level on some of the jars wax low though, so I topped it with a tad if tap water. Did I just kill all the bacteria?
