To ferment beets and carrots, you’ll need a simple saltwater brine, some clean jars, and a little patience while the natural bacteria do their thing.
This process—called lacto-fermentation—turns ordinary root vegetables into tangy, gut-friendly treats packed with probiotics.
If you’ve ever wondered how to ferment beets and carrots at home, you’re in the right place.
It’s easier than you might think, and once you learn how to ferment beets and carrots, you’ll want to make them all the time.
In this post, we’ll walk through why fermentation works, how to ferment beets and carrots step by step, and a few tips so your batch turns out perfect every time.
Let’s dive in.
Why Ferment Beets and Carrots?
Fermenting beets and carrots is one of the simplest ways to preserve these earthy, sweet vegetables while boosting their nutritional value.
Here’s why it’s worth your time.
1. Fermentation Creates Probiotics
When you ferment beets and carrots, beneficial bacteria like Lactobacillus multiply and convert sugars into lactic acid.
That lactic acid is what gives fermented veggies their signature tang and also acts as a natural preservative.
These probiotics support digestion and gut health, making fermented beets and carrots a smart addition to your diet.
2. It Preserves Nutrients
Unlike canning, fermenting beets and carrots doesn’t rely on high heat that can destroy vitamins.
Instead, fermentation keeps most of the vitamins, minerals, and fiber intact.
Beets are rich in folate and manganese, while carrots bring beta-carotene to the table—and fermentation helps your body absorb these nutrients more easily.
3. The Flavor Is Unbeatable
Fermented beets and carrots develop a complex, slightly sour taste that’s amazing on salads, sandwiches, or straight from the jar.
The natural sweetness of both vegetables balances beautifully with the tangy brine.
Once you try fermenting beets and carrots yourself, store-bought pickles just won’t compare.
How to Ferment Beets and Carrots Step by Step
Learning how to ferment beets and carrots takes just a few basic supplies and about 20 minutes of hands-on work.
Here’s the process.
1. Gather Your Ingredients and Equipment
For a one-quart batch, you’ll need about two medium beets and three to four carrots.
You’ll also need non-iodized salt (sea salt or kosher works great), filtered water, and a clean glass jar with a lid.
A weight to keep the vegetables submerged—like a glass weight or a small zip-top bag filled with brine—is helpful too.
2. Prep the Vegetables
Scrub your beets and carrots well, then peel them if you prefer.
Cut them into sticks, slices, or matchsticks—whatever shape you like.
Keeping the pieces roughly the same size helps them ferment evenly.
3. Make the Brine
Dissolve one tablespoon of non-iodized salt in two cups of filtered water.
This ratio creates a 2% brine, which is ideal for fermenting beets and carrots safely.
Stir until the salt is completely dissolved.
4. Pack the Jar
Tightly pack your beets and carrots into the clean jar, leaving about an inch of headspace at the top.
You can add garlic cloves, dill, or peppercorns for extra flavor if you like.
5. Add the Brine and Weight
Pour the brine over the vegetables until they’re fully covered.
Press the weight down to keep everything below the liquid—exposure to air can cause mold.
6. Ferment at Room Temperature
Loosely cover the jar and let it sit at room temperature, ideally between 65°F and 75°F.
After a day or two, you’ll notice bubbles forming—that’s the fermentation at work.
Taste your fermenting beets and carrots after three days, then every day until they reach the tanginess you love.
This usually takes anywhere from five to fourteen days.
7. Store in the Fridge
Once they taste right, screw the lid on tight and move your fermented beets and carrots to the fridge.
The cold slows fermentation down, so they’ll keep for several months.
Tips for Fermenting Beets and Carrots Successfully
Knowing how to ferment beets and carrots is one thing, but getting a perfect batch every time comes down to a few key habits.
Keep these tips in mind.
1. Keep Everything Submerged
The number one rule when you ferment beets and carrots is to keep them under the brine.
Vegetables poking above the surface can grow mold, so use a weight and check daily.
2. Use the Right Salt
Always use non-iodized salt when fermenting beets and carrots.
Iodine and anti-caking agents can inhibit the good bacteria you’re trying to grow.
3. Watch for Kahm Yeast, Not Mold
A thin white film on top is usually kahm yeast, which is harmless—just skim it off.
Fuzzy or colorful patches, on the other hand, mean mold, and you should toss the batch.
4. Trust Your Nose and Taste
Fermenting beets and carrots should smell sour and pleasant, like sauerkraut.
If something smells rotten or slimy, don’t eat it.
5. Experiment with Flavors
Once you’re comfortable fermenting beets and carrots, try adding ginger, bay leaves, or jalapeños.
Each batch is a chance to make the recipe your own.
So, How Do You Ferment Beets and Carrots?
You ferment beets and carrots by submerging them in a saltwater brine and letting beneficial bacteria do the work over several days.
The result is a tangy, probiotic-rich food that’s great for your gut and your taste buds.
Learning how to ferment beets and carrots at home saves money, reduces waste, and gives you full control over the flavor.
So grab some beets and carrots, mix up a brine, and start fermenting beets and carrots today—your gut will thank you.
