This easy fermented pickle recipe honestly seems like a pretty sorry excuse for a blog post.

I mean, really. How could anything with so few steps and ingredients ever be considered revolutionary enough to be worthy of your time, dear reader?

Well, if your garden overfloweth with homegrown cucumbers and/or you want to start incorporating more fermented vegetables into your diet,  I think you will love this super simple recipe.

Honestly, it has been a game changer for me with my last few cucumber harvests.

I remember last year, we ate more vinegar cucumbers, cucumber cream cheese sandwiches on sourdough, and plain old salted cucumbers than we could stand. 

Soon, I started making cucumber mint infused water by the gallon. But after all that, what else was a girl to do?

I mean, making fermented cucumber pickles is hard, right? Surely no mom of seven has time for that!

Now, I’m thinking, “Why the heck didn’t I just make more lacto-fermented pickles?!”

Read more on the benefits of fermented vegetables HERE.

Spoiler alert: there are only three ingredients in this recipe: cucumbers, water, and salt.

That’s it.

You may be thinking that fermenting vegetables is intimidating and scary.

Isn’t there some recipe that doesn’t require fermenting?

Yes, there are. But, guess what? They are actually HARDER than this simple recipe, and nowhere near as beneficial for the gut!

Homemade Fermented Pickles Are Super Simple To Make

Before I started fermenting vegetables myself, I was overwhelmed by all the options that I saw all over Pinterest. “How to Ferment Vegetables with Whey”, “Best Starter for Homemade Fermented Vegetables”, “Why Lacto Fermentation is the Best”, “Best Air Locks for Home Fermenting”…… Whaaaaaa?

For a few years I decided that fermenting was too difficult. I was going to go crawl in a hole and avoid any article that resembled a fermenting tutorial.

Friends, I’ve been there. If you’re where I was, let me gently back you off that ledge and give a quick science lesson.

Salt is a special little mineral that prevents the growth of harmful bacteria.

When ferments are submerged in a salt brine, the good bacteria present on the fresh vegetables, namely Lactobacillus, can proliferate and grow uninhibited by bad bacteria. It also helps turn sugars into lactic acid.

So, my point is… all you need for vegetable fermentation is salt, veggies, and water. The process really couldn’t be any easier and less intimidating.

Read about how to make homemade sauerkraut here and homemade kimchi here.

Think of fermentation as growing your own probiotics full of health benefits.

Now, on to the easy fermented pickle recipe.

We Love Fermented Foods!

We love these sour pickles, and you can bet I will be making many, many more this summer, as we are up to our ears in garden cucumbers.

For my next batch, I am going to just throw the freshly sliced cucumbers in the brine from the previous batch. Since it is already teeming with the beneficial bacteria, it will serve as a jump start for the process in the next batch.

Fermented vegetables, like these fermented pickles, can last six months or more in the refrigerator, IF you can go that long without eating them all up.

A Few Notes And Tips:

  • It is normal for the saltwater brine to get cloudy. This is a natural byproduct of vegetable fermentation and does not mean mold. For more fermented vegetable troubleshooting questions, check out THIS article.
  • Take one out and try it. If it is sour enough for you, put the lid on tightly, and throw the jar in the fridge. If you would like them to get a little more sour, leave them out at room temperature to ferment a little longer.
  • After you make your first batch, you can use some of the brine to make your next batch of probiotic pickles. It already contains a plethora of good bacteria, so you’ll be giving your next batch a head start. 
  • I like to use pink Himalayan salt. You could use sea salt or Celtic salt, but don’t use iodized table salt.

Fermented Pickles Ingredients:

Salt – Himalayan salt and sea salt are your best options. You don’t want to use iodized salt. Kosher salt may also be a good option, but it may contain anti-caking agents which you want to avoid.

Water – Preferably filtered water. City water can contain chlorine which can inhibit the good bacteria growth.

Cucumbers – Pickling varieties of cucumbers are the best choice because they contain less water and tend to stay crunchier than other types. You can use other types of cucumbers, but they may not have a great texture after fermentation.

What Type Of Pickles Should Be Used For Fermenting:

Pickling cucumbers work best due to their lower water concentration, but any cucumbers will work. 

  • Boston pickling cucumbers are my favorite.
  • Kirby
  • Bush pickle
  • National pickling cucumber
  • Calypso
  • northern pickling
  • Picklebush 
  • Carolina, just to name a few.
  • Kirby cucumbers

Choose small to medium sized cucumbers. Small cucumbers are the best. 

Salt In Fermentation:

I like to use Pink Himalayan Salt. You could use sea salt or Celtic salt, but don’t use iodized table salt.

Salt creates an environment that prevents bad bacteria from growing and allows the good bacteria, Lactobacillus, to thrive. It also helps keep the vegetables crunchy and slows down the fermentation process which helps add a lot of flavor. 

Tools you may need:

Half gallon glass jar. Quart jar will also work, I just like to make big batches at a time.

Fermenting weights

Fermenting lids

Berkey Water Filter (optional)

Knife

How To Make Lacto-Fermented Pickles:

adding salt to a large mason jars

Making the brine

Add four tablespoons of salt to a half gallon size mason jar.

Next, bring a couple cups of filtered water to a simmer. This is going to be used to dissolve the salt.

Add the hot water to the salt and stir to combine. Fill the jar the rest of the way with filtered water and set aside to cool.

Slice Cucumbers

Add sliced cucumbers to another half gallon mason jar. I like using small, firm pickling cucumbers.

I like to slice them in approximately half-inch rounds. If they are too thin, they can get soggy, and who likes soggy pickles?

Optional Add-Ins

Now, this is the part where you could get creative and add parsley, dill, cloves of garlic, or whole black peppercorns.

Emphasis on the COULD.

As in, you don’t have to.

My kiddos love these sour brine pickles, and I just don’t want to mess a good thing up. I’m afraid they would turn their noses up at garlic parsley pickles with peppercorns, and we wouldn’t want that.

If you want to make dill pickles, add about two heads of fresh dill per half gallon or some dill seeds.

I added some parsley for the photo, but like I said, I just pulled that little sprig right back out and got on with my plain Jane pickle makin’.

After the salt water brine has cooled, add it to the jar of cucumbers, leaving at least 2 inches of headspace at the top.

Add a Weight

Add a fermentation weight to keep the sliced cucumbers under the brine. You want to make sure the cucumbers stay under the brine to prevent mold from developing.

Screw on the Lid

After the cucumbers are weighed down in the salty brine, cover the jar with a fermentation lid and place the jar ring on loosely.

Fermenting does create some natural gases that need to be released, so if you are not using a fermentation lid, don’t screw the lid on too tightly. However, do keep it covered so flies and varmints don’t decide to feast on your pickles.

You can also use these Pickle It fermenting lids, but you definitely don’t have to. The purpose of the lids is to allow gases to escape, while letting nothing else in.

I use them all the time, but they were already in use in other ferments when I was making this tutorial. You can pretty much accomplish the same thing with a loose lid.

Place in a dark place out of direct sunlight.

Allow to ferment until desired taste is reached. This can be 3-5 days if they are in a warm place, or longer depending on the environment.

FAQ:

How long does it take to ferment pickles?

It usually takes 5-7 days for the fermentation process. After five (or so) days, they will usually taste perfectly pickle-ish.

What is the salt-to-water ratio needed for fermentation?

The salt-to-water ratio is commonly between 2-5%. Somewhat depends on taste. Most recipes will call for about 2 tablespoons of salt per quart of water.

Can fermented pickles make you sick?

There is a low risk of pickles making you sick. Always make sure your tools and jars are very clean. Always check for signs of mold and toss if there is mold.

How do you keep homemade pickles crunchy?

If you want your pickles to stay really crunchy you can add a grape leaf to them. This is totally optional, but the tannins in the grape leaf help keep that crunch.

What is brine pickling?

Brine pickling is the process of preserving with salt water.

What is pickle brine made of?

Water and salt. It is that simple. You can also add other herbs and spices if desired.

Is brine the same as vinegar?

No, they are different. Brine refers to a salt-water mixture, while vinegar is an acidic liquid made from the fermentation of alcohol.

Are all pickles lacto-fermented?

No. Most store bought pickles are not lacto-fermented unless stated on the label. Due to the canning process, all the good bacteria produced during the fermenting process would be killed. 

Is lacto-fermentation the same as pickling?

No, lacto-fermentation has the presence of good bacteria that ferments and helps preserve the vegetables. Whereas, pickling is the process of soaking vegetables in a mixture of vinegar, salt, and water which gives it a sour taste.

What do lacto-fermented pickles taste like?

They have a salty, tangy, and slightly acidic flavor. 

Can I add other spices to fermented pickles?

Yes. Add garlic cloves, dill, mustard seeds, red pepper flakes (for some heat), bay leaves, etc.

What vegetables can you lacto-ferment?

There are lots of vegetables you can lacto-ferment like: beets, cabbage, carrots, cauliflower, cucumbers, garlic, green beans, kohlrabi, peppers, radishes, snap beans, tomatoes (we love making fermented salsa), turnips, and zucchini. I created a whole guide on how to lacto-ferment vegetables here.

How To Make Crunchy Pickles

Typically, I find that my pickles stay pretty crunchy, but if you are struggling with mushy pickles, you can add something that has tannins in it like oat leaves or grape leaves. Adding tannins is an easy way to ensure you get crunchy pickles.

    I like that you’ve tried to make sure people aren’t intimidated by the process, but I wish their were more recipes that simplified it even more with salt ratios. For example I like to do it with a 3% brine. It’s incredibly simple and easy to scale up or down the batch size. You simply add 30 grams of salt per litre of water. Tare the jar your using on some scales and add your veggies to it and add 3% of salt, ie if you have 500 grams of cucumbers, add 15 grams of salt to the jar and pour your already made 3% solution to the jar. It will dissolve pretty quickly. Another thing is most people don’t have access to grape or oat leaves, but almost everyone has black tea, which contains tannins. 1 bag of tea per litre is pretty good.

    1. Cynthia A Holt says:

      Dill seed or dill heads as well as Bay leaves contain tannins.

  2. Brianna says:

    How and in what measurements can we use brine from our previous jar to make more? These were the best pickles we’ve ever eaten.

    1. Lisa Bass says:

      I usually just pour about a cup of brine from my previous ferment into a new jar. It helps give them a jumpstart on the fermenting process.

  3. Bryan Groves says:

    Is it necessary to heat the water to dissolve the salt, or does it dissolve it quickly and more completely with hot water?

    1. Lisa Bass says:

      Yes, heat the water.

  4. Tiff Mccormack says:

    Each time I’ve tried to lacto ferment cucumber slices they come out mushy and slimy after two or three days. What am I doing wrong? Any help would be appreciated.
    Tiff

    1. Lisa Bass says:

      My guess is that your water was probably too warm. It’s important that the cucumbers stay very cold in order to preserve their crispness.

  5. Wanda Schnell says:

    What if there is mold on the top of the jar? is it still good? and what would have caused it?

    1. Lisa Bass says:

      It’s caused by food particles floating to the top. Even the tiniest piece of dill could cause mold. Anything that catches the air! I would start over and then use a weighted glass to make sure everything is below the brine.

    Love your content!! I’m new but will subscribe. I love fermented food so it’s nice to have a simple recipe 😋 thanks!

  7. Kathy E says:

    How long will these keep in the fridge?

    1. Lisa Bass says:

      Fermented foods can store for months in the fridge.

  8. Nikki says:

    I don’t have half gallon mason jars but I do have quarts, can I divide it using this recipe accordingly?

    1. Lisa Bass says:

      Yes, that’s fine!

  9. Esty says:

    Thanks so much! This was very informative! Can I add apple cider vinegar to the pickle brine (since it is a fermented vinegar)? or does the brine need to be made strictly with only salt in order to ferment the cucumbers?
    Thank you!

    1. Lisa says:

      Supposedly. you can, haven’t personally tried it, but adding too much can be detrimental to the ferment as it can slow fermentation down. They also get tangy without it. If you want to add vinegar, you may want to go the refrigerator pickle route, or wait until after the ferment to add the vinegar. That way you can taste it to decide if it needs it.

  10. kib says:

    Laziest cheapest fermenting weight ever: took a flat rock from my garden slightly smaller than the opening of my jar, scrubbed it and then put it through the dishwasher for good measure. wrapped it in cheesecloth to make a little “packet” with a “handle”.

    1. Dr. Ferman says:

      This is a really bad idea. Rocks are porous and may contain bacteria that are microscopic and cannot be scrubbed away. Also, rocks may contain minerals that will react to the fermentation process, ruining it and/or making you sick.

    2. Hugh says:

      My Eastern European grandmother, b.1888, made pickles regularly for decades and weighted them down on the jar with what she called “my pickle rock.” I continued the tradition with rocks from my garden. Yeah, just clean them and you’re fine.
