An easy homemade tutorial on how to ferment vegetables in a mason jar.
You’re probably thinking I’ve caught the hippie train straight out of here with this post but hear me out.
Do you like pickles? Yes? (note -you should check out this post on how to make simple homemade pickles and spicy garlic dill pickles if so).
Ok then, you’re going to like fermented vegetables.
So read on.

Unfortunately, I had to be on antibiotics 3 times over the last 6 months.
I absolutely hate taking them and believe me, if there was a way I could’ve avoided it, I would’ve.
I’m a huge proponent of probiotics so while I was filling prescriptions in the drug store these past few months, I was simultaneously buying some kick ass probiotics to try and help keep some good bacteria in my system.
And let me tell you, the *good* probiotic pills, yeah, well they’re costly.
Six times more costly than the antibiotics in fact.
So, when the second round of antibiotics came around, I decided that instead of spending $30 on probiotic pills and $4 kombucha bottles every time I ventured into the hippie-mart (my loving name for the local natural foods store), I should probably look into this whole lacto-fermented vegetable thing.
Lacto-fermented vegetables
Lacto-fermented…it sounds crazy, right?
First thing I thought was “wait, there’s milk in this?”
Um, no. Lacto, in this case, doesn’t refer to milk, it refers to lactic-acid.
The naturally occurring bacteria on fruits and vegetables is called lactobacillus. When they’re placed in an oxygen free environment, the bacteria convert sugar into lactic acid which is what gives fermented foods their characteristic tangy/sour flavor.
So now that the science lesson is out of the way, here’s the cool part:
Vegetables + water + salt + a few days = a probiotic powerhouse of tangy vegetable deliciousness.
Bonus: it doesn’t cost $30 and they’ll last in the fridge for months.
How to Ferment Vegetables
What you’ll need to ferment vegetables:
- 1 quart wide mouth mason jar
- plastic lid
- sea salt
- water
These are the basics. There’s a whole world of fermentation supplies that can be purchased to make the process both easier and safer once you’ve got the method down.

You can literally ferment whatever vegetables you like. If you ferment cabbage you get red cabbage sauerkraut!
They’re perfect for snacking on or adding to your meals for a probiotic boost.
I’ve been adding them to salads, on top of my protein with lunch or dinner or, just picking at them throughout the day when I’m bored.
I do the same with pickled garlic scapes – another vegetable that transforms into a tangy delight once fermented/pickled.
Yeah, a lot of that.
And this is where I’m going to sound like a total nerd, but every time I eat them I silently say “take that, antibiotics.”
Kimchi is an Asian version of fermented vegetables so if you like that, you’ll definitely like these fermented vegetables.
Also make sure to try out this bulgogi kimchi rice plate and this kimchi potato hash.

Can you really stop taking probiotics if you eat fermented veggies each day?!!! Also I did not leave an inch at the top of my jar – the recipe did not tell me to do that.
Will it still ferment properly?
@Christina, it will ferment. But, as gasses begin, it may overflow. The point of the cabbage leaf was to keep the veggies submerged. You do not want them exposed to the air. So, if the liquid overflows, be sure all the veggies are still submerged, even if you must take a few out. You do not want them to rot!
I am wanting to can my vegetables after they are fermented for longer keeping. Is this advisable? Any advice?
Sorry, I don’t can and have never tried that with these fermented vegetables. I assume you would do it as you would with any other canning process?
@Gina Matsoukas, wouldn’t the high heat required for canning destroy the probiotics?
Yes, it would. Didn’t say it wouldn’t but you “can” can the vegetables for longer shelf life. If you want a longer shelf life that maintains the probiotics and beneficial qualities of fermentation, transfer them to a refrigerator or freezer.
@CANDY, I was thinking the same because I’d love to make a big batch! But, I also thought that canning would cook them, therefore make them mushy. In the end, I think it best to make one at a time. You can get a gallon or half gallon cannon jar. That ought to last a long time!
Antibiotics are horrible, yet sometimes we must take them. I found I have a skin disease,”almost” directly related to Celia Disease. PLEASE take your probiotics.
Was a spelling mistake in my comment 🙈 I did put salat leaves on the top of veggies but I did put few not one…
Thank you, for nice and simple recipe! I did radishes, carrot, onion and broccoli today, instead of cabbage leaf I put on the top of jar the salt leaves, hope it will be OK… And didn’t have plastic lid… So I just put on the top clean film and put over rubber bund to keep it sealed… Thank you again! 🙏
Where do I find plastic lids to put over the jars?
There’s a link to them on Amazon in the post if you scroll up or you can find them here: https://amzn.to/3mEFB5s
@Ruth Pumphrey, Walmart carries them
@Ruth Pumphrey, walmart has in the jar asile
Can I put sugar in this recipe?
I don’t recommend that during the fermentation process. You could add it at the end if you want to incorporate the sugar for taste purposes but if you’re thinking to speed up the fermentation process, I haven’t tried that and can’t speak to the impact it would have.
Thank you…thank you the best & easiest recipe ever, your the best.

Here’s a helpful brine calculator. The salt part can be confusing, but this tool can be very helpful. For those asking if you can drink the brine, the answer is “heck yeah!” It’s so good for you. And you can use a little in a new batch of fermented veggies to help get your ferment started, but it’s not necessary.
The recipe from a guest from Dr Oz’s Show was:
Equal parts water and vinegar with a tablespoon of
sugar.
Let it sit out in a mason jar/ with lid for two days.
Then put it in the fridge.
keeps for months.

@Julie, that sounds like pickling, not fermenting
Is it okay to use alkaline water?
I haven’t tried but would assume so.
@Jeri, I use spring
