Fermenting beets and carrots is a simple, old-school way to preserve your harvest while boosting flavor and gut-friendly probiotics.
If you’ve ever wondered how to ferment beets and carrots, the answer is easier than you might think.
You basically need salt, water, and a little patience, and you’ll have crunchy, tangy fermented beets and carrots ready to enjoy.
Both vegetables ferment beautifully on their own or together, and the process is very forgiving for beginners.
In this post, we’ll walk through how to ferment beets and carrots step by step, plus some tips to make sure your ferment turns out great every time.
Let’s get fermenting.
Why Ferment Beets and Carrots?
Fermenting beets and carrots is worth your time for a few tasty reasons.
1. Probiotics for Your Gut
When you ferment beets and carrots, beneficial bacteria multiply and turn the natural sugars into lactic acid.
That lactic acid acts as a natural preservative and gives you a dose of probiotics with every bite.
Eating fermented beets and carrots can support digestion and give your gut microbiome a healthy boost.
2. Better Flavor and Texture
Raw beets can taste a bit earthy and raw carrots a little plain, but fermenting transforms both.
The process softens their bite just slightly while keeping them crunchy, and adds a tangy, slightly sour flavor that’s downright addictive.
Fermented beets and carrots also pair well with sandwiches, salads, and charcuterie boards.
3. Long Shelf Life Without Canning
You don’t need a pressure canner or fancy equipment to ferment beets and carrots.
Once fermented, a jar of beets and carrots can last for months in the fridge.
That makes fermenting beets and carrots a practical way to use up a big garden harvest without stressing about spoilage.
How to Ferment Beets and Carrots Step by Step
Here’s the basic method for fermenting beets and carrots at home.
1. Gather Your Ingredients and Tools
To ferment beets and carrots, you’ll need fresh beets, fresh carrots, non-iodized salt (sea salt or pickling salt works great), filtered water, and a clean glass jar.
A weight or a small zip-top bag filled with brine helps keep the vegetables submerged.
You can also add garlic, dill, peppercorns, or bay leaves for extra flavor when fermenting beets and carrots.
2. Prep the Vegetables
Scrub your beets and carrots well, then peel them if you like.
Cut them into sticks, coins, or matchsticks, keeping the pieces roughly the same size so they ferment evenly.
Smaller pieces of beets and carrots ferment faster, while larger chunks stay crunchier longer.
3. Make the Brine
The standard brine for fermenting beets and carrots is about one tablespoon of salt per two cups of filtered water.
Stir until the salt fully dissolves.
This saltwater solution creates the environment where the good bacteria thrive and the bad stuff can’t survive.
4. Pack the Jar
Tightly pack your beets and carrots into a clean glass jar, leaving about an inch of headspace at the top.
Add any spices or garlic between the layers as you go.
Pour the brine over the beets and carrots until they’re completely covered.
5. Keep Everything Submerged
This is the most important rule when fermenting beets and carrots.
Anything sticking above the brine can grow mold, so use a weight, a clean stone, or a baggie of brine to hold the vegetables down.
Then cover the jar loosely with a lid or a cloth secured with a rubber band.
6. Let Them Ferment
Leave your jar at room temperature, ideally around 65–72°F, away from direct sunlight.
Fermenting beets and carrots usually takes about one to three weeks, depending on the temperature and your taste.
Check them every couple of days, press the vegetables back under the brine, and taste as you go.
7. Move to Cold Storage
Once your fermented beets and carrots taste tangy and delicious, seal the jar with a tight lid and move it to the fridge.
The cold slows fermentation down and keeps your beets and carrots fresh for months.
Tips for Fermenting Beets and Carrots Successfully
A few small habits make a big difference when fermenting beets and carrots.
1. Use Fresh, Firm Vegetables
Fresh beets and carrots ferment better and stay crunchier than older, soft ones.
Skip any vegetables with bruises, soft spots, or mold, since those can ruin your batch.
2. Keep It Clean
Wash your hands, jar, and tools well before fermenting beets and carrots.
Clean equipment keeps unwanted bacteria out and gives the good bacteria a head start.
3. Don’t Fear the Bubbles
Bubbles, a slightly cloudy brine, and a fizzy smell are all normal signs that your beets and carrots are fermenting properly.
Just skim off any white film that appears on the surface, since that’s usually harmless yeast.
4. Trust Your Senses
Fermented beets and carrots should smell sour and taste tangy, not rotten or moldy.
If something smells off or you see fuzzy colored mold, toss the batch and start fresh.
So, How Do You Ferment Beets and Carrots?
You ferment beets and carrots by packing them into a jar, covering them with saltwater brine, and letting beneficial bacteria do their thing at room temperature.
Once they taste tangy and sour, you move them to the fridge and enjoy them for months.
Fermenting beets and carrots is one of the easiest fermentation projects you can try, and the results are crunchy, flavorful, and great for your gut.
