To ferment cabbage and carrots, you’ll combine shredded veggies with salt and let beneficial bacteria do the work.
This simple process creates a tangy, crunchy, probiotic-rich food you can enjoy for months.
Whether you’re a total beginner or have some kitchen experience, fermenting cabbage and carrots is one of the easiest fermentation projects you can try at home.
In this post, we’ll walk through exactly how to ferment cabbage and carrots, what tools you need, and how to avoid common mistakes along the way.
Let’s dive in.
How to Ferment Cabbage and Carrots
Fermenting cabbage and carrots is straightforward once you understand the basic process.
The key is creating an anaerobic environment where lactic acid bacteria can thrive while harmful bacteria can’t survive.
Here’s how it works step by step.
1. Gather Your Ingredients and Tools
To ferment cabbage and carrots, you’ll need just a few simple things.
You’ll want one medium head of green cabbage, about three to four medium carrots, and one to two tablespoons of non-iodized salt.
Sea salt or kosher salt works great, but avoid table salt with anti-caking agents since those can inhibit fermentation.
For tools, grab a large bowl, a sharp knife or mandoline, a cutting board, a clean glass jar, and something to weigh down the veggies like a fermentation weight or a small ziplock bag filled with water.
2. Shred and Mix Your Vegetables
Start by removing the outer leaves of your cabbage and cutting it into quarters.
Remove the core, then slice the cabbage as thinly as you can.
Next, peel your carrots and shred them using a box grater or julienne peeler.
Add both to your large bowl, sprinkle the salt over everything, and start massaging.
You’ll want to massage the cabbage and carrots for about five to ten minutes until they start releasing liquid.
This liquid is your brine, and it’s essential for fermenting cabbage and carrots properly.
3. Pack Everything Into a Jar
Once your veggies are nice and juicy, grab handfuls and pack them tightly into your clean glass jar.
Press down firmly with your fist or a tamper after each handful to eliminate air pockets.
The goal when you ferment cabbage and carrots is to keep everything submerged under the liquid.
If your veggies aren’t fully covered by their own brine, you can add a little extra salted water (one teaspoon of salt per cup of water).
Leave about an inch of headspace at the top of the jar.
4. Weight It Down and Cover
Place your fermentation weight on top of the veggies to keep them pushed below the brine.
If you don’t have a weight, a cabbage leaf folded on top with a small clean stone works fine.
Cover the jar with a lid, but don’t seal it too tightly since gases need to escape during fermentation.
An airlock lid is ideal, but a regular lid loosened slightly works in a pinch.
How Long Does It Take to Ferment Cabbage and Carrots?
The time it takes to ferment cabbage and carrots depends on your room temperature and personal taste.
In general, you’ll want to let them sit at room temperature (around 65 to 75°F) for anywhere between five and fourteen days.
Warmer temperatures speed things up, while cooler temps slow fermentation down.
Start tasting your ferment after day three or four.
When you ferment cabbage and carrots, you’re looking for a tangy, slightly sour flavor with a pleasant crunch.
Once it hits that sweet spot, move the jar to your fridge.
The cold temperature slows fermentation to a crawl, so your ferment will keep for several months.
Signs Your Ferment Is Going Well
You’ll notice bubbles rising to the surface during the first few days, and that’s a great sign.
The brine may look cloudy, which is completely normal.
A slight fizzy smell when you open the jar means lactic acid bacteria are hard at work.
Signs Something Went Wrong
If you see fuzzy mold (not just white kahm yeast), slimy texture, or smell something rotten, toss it out.
Kahm yeast is a flat white film that’s harmless, but fuzzy mold means you should start over.
Tips for Fermenting Cabbage and Carrots Successfully
Getting the best results when you ferment cabbage and carrots comes down to a few key practices.
Here are some tips that make a big difference.
1. Keep Everything Submerged
The number one rule when you ferment cabbage and carrots is keeping the veggies below the brine.
Exposure to air invites mold and spoilage.
Check your jar daily and press things down if needed.
2. Use the Right Amount of Salt
Salt controls which bacteria grow during fermentation.
Too little salt and harmful bacteria can take over; too much and fermentation stalls.
A good ratio when you ferment cabbage and carrots is about two percent salt by weight.
3. Maintain a Clean Environment
Always use clean hands, clean jars, and clean tools.
You don’t need to sterilize everything like you’re canning, but basic cleanliness goes a long way.
4. Be Patient and Taste as You Go
Fermenting cabbage and carrots isn’t an exact science.
Every batch tastes a little different depending on temperature, salt, and timing.
Trust your taste buds and adjust from there.
So, How Do You Ferment Cabbage and Carrots?
To ferment cabbage and carrots, you simply shred them, salt them, pack them into a jar, and let nature take its course.
The whole process takes just a few minutes of hands-on work, then patience does the rest.
Once you learn how to ferment cabbage and carrots, you can experiment with added garlic, ginger, or hot peppers for new flavor twists.
So grab some cabbage and carrots, and start your first batch today.
