Brine & Pickling Guide
Fermented Vegetables: Examples & Full List
A complete list of fermented vegetables with examples — from sauerkraut and kimchi to fermented carrots, beets, green beans, and hot sauce. What can be fermented, how they differ, and how to start your own.
What counts as a fermented vegetable?
A fermented vegetable is one preserved by lacto-fermentation: submerged in a salt brine, its natural sugars are eaten by beneficial Lactobacillus bacteria that live on the vegetable's own skin. Those bacteria produce lactic acid, which lowers the pH, preserves the vegetable, and gives it that clean, tangy sourness. The result is alive with probiotics — the opposite of a vinegar quick-pickle, which is simply soaked in acid and never ferments.
The beauty of it is how few ingredients you need: a vegetable, salt, and time. Almost any firm vegetable can be fermented this way, which is why the list below is so long. If you want to make your own, the salt ratio is the one number that matters most — dial it in with the fermentation brine calculator or the salt brine calculator before you pack the jar.
The classic fermented vegetables
These are the famous ones — the ferments most people have tasted, and the best place to start.
- Sauerkraut: shredded cabbage salted in its own juices. The archetypal fermented vegetable and the easiest first project.
- Kimchi: napa cabbage and radish with chilli, garlic, ginger, and fish sauce. Spicier and more complex than kraut — see our kimchi explained guide.
- Fermented (sour) pickles: whole cucumbers brined with dill and garlic — the deli-style sour pickle, not the vinegar kind.
- Curtido: the tangy Salvadoran cabbage, carrot, and oregano slaw served with pupusas.
- Giardiniera: a mix of cauliflower, carrot, celery, and peppers, fermented rather than jarred in vinegar.
Root vegetables
Dense roots are some of the best-behaved ferments because they stay firm and crunchy for weeks.
- Carrots: whole sticks or coins, often with garlic, ginger, or dill. Crisp, sweet, and beginner-friendly.
- Beets: sliced or grated; the base for beet kvass, a tangy fermented tonic.
- Radishes: including daikon — mild, peppery, and fast to ferment.
- Turnips: the pink, garlicky Middle Eastern torshi stained with beet.
- Celeriac, parsnip & kohlrabi: less common but excellent grated into mixed ferments.
Everyday vegetables
- Green beans (dilly beans): crunchy, garlicky, and a reliable first ferment.
- Cauliflower: holds its bite and takes on spice beautifully.
- Peppers & chillies: the base of fermented hot sauce — see below.
- Cabbage (whole leaf): beyond kraut, whole leaves make wrappers for Korean and Eastern European dishes.
- Brussels sprouts: halved and brined, they turn tangy and nutty.
- Okra, asparagus & broccoli stems: all ferment well in a straightforward brine.
Alliums, aromatics & condiments
Some of the most useful ferments are not eaten on their own but built into everyday cooking.
- Garlic: whole cloves mellow into something sweet; honey-fermented garlic is a favourite.
- Onions & shallots: sliced and brined for a tangy, pickle-like topping.
- Ginger & turmeric: grated into brines or fermented as a "bug" for sodas.
- Fermented hot sauce: chillies brined for a week or two, then blended — deeper and rounder than vinegar sauce.
- Fermented salsa & relishes: tomatoes, peppers, and onions soured naturally.
Which vegetables ferment best?
The rule is simple: the firmer and denser the vegetable, the better it holds up. Cabbage, carrots, radishes, beets, cauliflower, and green beans stay crisp for weeks. High-water vegetables like cucumbers, courgette, and tomatoes are more prone to going soft, so they benefit from a source of tannins — a grape, oak, or blackcurrant leaf, or a pinch of black tea — to keep them crunchy. Leafy greens ferment fast but wilt, so they suit quick, punchy ferments rather than long storage.
Whatever you choose, keep everything submerged under the brine. Vegetables that poke above the liquid are where mould and off-flavours start, so use a weight and pack the jar tight.
Fermented vs. quick-pickled
It is worth repeating because it is the single biggest point of confusion. A quick pickle is preserved in hot vinegar and is ready in hours, but it is not alive and has no probiotics. A fermented vegetable makes its own acid over days or weeks through live bacteria, so it is tangy, fizzy, and full of gut-friendly microbes. If you see "lacto-fermented," "brined," or "naturally soured" on a label, it is the real, living kind.
FAQs
What are some examples of fermented vegetables?
The most common examples are sauerkraut (cabbage), kimchi (napa cabbage and radish), pickles (cucumbers), and fermented carrots, beets, radishes, green beans, cauliflower, garlic, peppers, and onions. Almost any firm vegetable can be lacto-fermented in a salt brine.
What vegetables ferment the best?
Firm, dense vegetables ferment the best because they stay crisp: cabbage, carrots, radishes, beets, cauliflower, green beans, and peppers are all excellent. Cucumbers and other high-water vegetables can go soft, so they often need tannins (like a grape or oak leaf) to keep them crunchy.
Is fermenting vegetables the same as pickling?
Not quite. All lacto-fermented vegetables are pickles, but not all pickles are fermented. Quick pickles are preserved in vinegar and are not alive. Fermented vegetables are preserved by beneficial bacteria that produce their own lactic acid, which is what makes them tangy and probiotic.
How long do fermented vegetables take?
Most vegetables ferment in about 1 to 4 weeks at room temperature. Softer or thinly sliced vegetables and warmer rooms ferment faster; whole or dense vegetables and cooler rooms take longer. Taste as you go and move the jar to the fridge once the flavour is where you like it.
Do all fermented vegetables need a starter culture?
No. Vegetables carry their own wild lactic-acid bacteria on their skins, so a simple salt brine is all you need for wild fermentation. Some recipes add whey or a starter to speed things up, but it is not required for sauerkraut, kimchi, or most brined vegetables.
Start your own batch
Every vegetable on this list starts the same way — the right salt in the right amount of water.
