Probiotic-Packed “Pickled” Fermented Dilly Green Beans

While you can ferment pretty much any vegetable, some veggies seem like they were made to be fermented. Beans definitely fall into that category! Fermented green beans are tangy, crunchy, and downright delicious. It takes extreme willpower to stop eating these right out of the jar! The good news is: they’re so healthy for you, it is totally okay if you don’t stop. The other good news? They’re really easy to make.

Another popular way to preserve green beans is to pickle them. The fermentation process preserves them as well, but also introduces millions of gut-healing probiotics, enzymes, and antioxidants. It keeps the food alive, rather than sterilizing it! That is why we typically choose to ferment foods over using a vinegar brine to pickle them. However, if you’re interested in a more classic pickle, we do have an awesome vinegar brine recipe! We use it to achieve a classic pepperoncini flavor with our pickled peppers, but the recipe can be used for any veggie – including greens beans!

Even if you don’t have homegrown green beans to use for this recipe, I highly suggest giving it a go anyways! Pick up some beans from your farmer’s market or local grocery store. But remember, it is always best to choose organic produce for ferment recipes. Inorganic produce can interfere with a safe fermentation process, and also produce off-flavors.


A pair of hands holds a bunch of beans that are splayed out as one would a deck of cards. The colors range from green to purple to combinations of the two. There is a gravel pathway beneath the beans and it is lined with yellow yarrow, purple salvia, and various colors of river cobble rock lining the pathway.
A handful of beans to ferment. The classic green beans are Provider bush beans, the spotted red are Borlotti, the spotted purple and white are Dragon Tongue, and the dark solid purple green beans are Royal Burgundy. Another new favorite variety that isn’t show in this bunch is these Musica Romano pole beans. They stay so tender, even when allowed to grow very large!


SUPPLIES


  • A fermenting vessel – Some folks use ceramic crocks, but many homesteaders and herbalists these days simply use mason jars of varying sizes. For smaller batches, use a pint or quart jar. For larger batches, we use these half-gallon mason jars.
  • Fermenting lid or air lock device – The use of a lid made for the fermentation process is ideal, which makes the job much easier and pretty foolproof, though a regular jar lid can be used with a few tweaks. Examples of fermenting lids include an all-in-one device like a Kraut Source lid, or the use of a combination of items like a glass or ceramic weight along with another type of air lock lid. A further discussion of their reasoning and use will follow in the directions section below.
  • Organic Green Beans – As many needed to fill your ferment vessel of choice.
  • Salt – Sea salt or kosher pickling salt. Do not use iodized table salt! It messes with the flavor and process. We love this Celtic sea salt for our ferments.
  • Filtered water
  • Fresh Dill – 1 bunch
  • Optional: Garlic, peppercorns, chili peppers, or red chili flakes



DIRECTIONS


1) Clean Supplies

You want to make sure all of your supplies are clean. No, they don’t need to be insanely clean or “sterile”. You actually never want to use bleach (or even soap) on your fermenting tools! The residual could stick around and really make things taste “off”. We spray ours with plain white vinegar, and then rinse well with hot water. That’s it. I do the same with my hands.


2) Prep Green Beans

Rinse off the beans. Like the other supplies, they don’t need to be crazy sterile-clean. Avoid using soap or produce washes! For this recipe, it is best to use your most tender green beans, and avoid using the tough ones. The beans will soften just slightly as they ferment, but not nearly the same as cooking tough beans to tenderize them.

To prep the beans, trim off the hard stem end. That is it! You could cut them into bite-size pieces if you desire, though we generally leave them whole or in halves.


3) Add Seasonings of Choice

In the bottom of your chosen fermenting vessel, add some washed fresh sprigs of dill. I suggest this simple “seasoning” at minimum. As long as you don’t dislike dill, it provides a very mild and delicious addition! The amount of dill doesn’t need to be precise. If you get the smaller plastic clamshell packages, use about half for a quart jar, and the whole thing for a half-gallon jar. If you’re able to get a larger, looser bunch of dill, we generally use about a quarter of those per quart jar, and half a large bunch per half-gallon jar.

We also usually add a couple cloves of fresh garlic at the bottom of the jar. If you don’t like dill or garlic, you can totally skip either and keep it super simple! Or if you loooove garlic, you can add more. Personally, we have found that fermented garlic can overpower the flavor of everything else if you go too heavy. We find about 1-2 cloves of garlic in a quart jar, and 3-4 cloves per half-gallon jar is our sweet spot. (These were small cloves, so we added 3 in this quart.)

You can also get creative here and go beyond what this basic recipe is calling for. For example, add a pinch of peppercorns, a sprinkle of celery seed or mustard seeds, a chunk of fresh ginger or turmeric, a dash of red chili flakes, or even a whole hot chili pepper or two – if you want some heat! That’s the beauty of fermenting. The options for experimentation and creativity are endless. Keep in mind that flavors usually mellow out when fermented too. For example, hot chilis will become much less spicy than when eaten raw or even cooked once they’re fermented. 


The bottom of a quart mason jar is shown from the top, inside contains a few sprigs of dill, three cloves of garlic, and ten or so peppercorns.



4) Pack the Jar

Once you have your chosen seasonings at the bottom, start adding greens beans to the jar. When fermenting, it’s best to try and fit as many veggies in the jar as possible. If you’re going through this process, you might as well maximize the amount of cultured food you get out of it in the end! This will also reduce the amount of brine needed, and the amount of air that can get trapped inside. Therefore, when you’re putting the green beans into the jar, try not to just throw handfuls in there all haphazardly. I like to lay the jar on its side as I add the beans, which makes it easier to pack them in together.


A two way image collage, the first image shows a quart mason jar stuffed to the brim with green beans of varying types. They range in color from purple to green and some are a mixture of both colors. They have been placed inside the jar whole, with only the stem end cut off, they are also pointing top to bottom to maximize space and fit the most beans inside the jar as possible. the second image shows the inside of the jar from the top, the ends of the beans are pointing upwards, looking as if they are trying to escape.



5) Make a Brine

The standard brine ratio for fermented vegetables is 1 tablespoon of sea salt or kosher salt per 2 cups filtered water. With a fully-packed jar of veggies, we have found that 2 cups of brine is adequate per quart jar. Scale up or down as needed.

On the stovetop, heat a pot with filtered water to just warm enough to dissolve the salt. You do not want to add hot brine to your ferment, but lukewarm is okay. Too much heat will kill the beneficial bacteria (lactobacillus) needed to safely ferment your beans!

Once cooled, slowly pour the brine into the jar until the beans are completely covered. Pockets of air are likely trapped in there, so give the jar a little tap and wiggle to help release them.


A two way image collage, the first image shows the full quart jar of beans while a stream of brine is pouring in from the top. The second image shows the jar from the top, it has been filled with the brine and there are air bubbles floating along the top of the brine. This illustrates the air pockets that have been set free from below the brine level, ensuring a safe and effective ferment.



6) Add a Weight

This is an important step in fermenting foods! The beans need to stay submerged below the brine level. If they’re allowed to float or be in contact with air, mold can develop! 

The stainless steel all-in-one Kraut Source fermentation lids we use have a flat plate and spring inside that help to easily accomplish this, acting as a weight to keep everything down. Another option is to use a ceramic or glass weight made for fermenting. Some people get resourceful and use other clean items that fit inside their vessel, like a boiled rock or smaller glass jar. 


A hand is in the process of placing a Kraut Source unit (lid) on the jar. The Kraut Source unit makes for quick, easy, and safe fermenting.



7) Cover

Next, the jar or container of fermenting green beans needs to be covered with a tight fitting lid. The use of an air-lock lid made for fermenting is preferable. Aid lock lids allow for the release of any excess air and carbon dioxide that is produced during fermentation, without allowing new air or anything else to come in.

This is one reason why we really love the Kraut Source lids! They not only have a weight that keeps everything submerged, but also have a little moat on top that you fill with water, thus creating an air lock. However, there are a lot of other mason jar fermentation lids out there too! Here are some silicone nipple types. These would need to be used in conjunction with a weight of some sort, like these glass ones.

If you do not have an air lock lid, you can try using a regular mason jar lid. Screw it on tightly, and then make sure to quickly “burp” your jars every few days to release the built up carbon dioxide. Sometimes this works, though I have heard mixed reviews. I suppose they make air lock lids for a reason…


The jar is shown with the Kraut Source unit now installed on top of the jar, in place of its traditional lid.
If you’re using a Kraut Source, keep that little moat full of water!


8) Ferment

Once it’s all put together, let your dilly bean concoction sit out at room temperature for 7-14 days to do its thang. The total time depends on your personal flavor preference, and the temperature of your house. We let most of our ferments go for about 10-14 days.

Warmer conditions will ferment things more quickly, and cooler does just the opposite. The ideal fermentation temperature is around 70 to 75 degrees Fahrenheit. If it is summer time and your house is warmer than this, try to find a slightly cooler location for your vessel to hang out. Too hot of conditions can encourage the development of white Kahm yeast. It is not dangerous, but rather stinky and off-putting.   


Notes during fermentation:

During the week or two at room temperature, you will notice the fermented green beans start to undergo change. The lactobacillus is working away to convert the starches in the food into lactic acid, which preserves it. In the process, carbon dioxide is formed, so you’ll probably see some bubbling activity in there! The green beans will also start to change color, fading to a less bright green. The brine also gets cloudy, and this is totally normal!

If you are using a Kraut Source lid, keep an eye on its little water-filled moat, making sure it always has some clean water in there. It doesn’t dry out easily though. On the other hand, our vessels usually overflow from the lid for the first several days of fermentation. Be forewarned that yours may do the same! So we alway set the jars on a plate or in a bowl to catch the overflow. Once that initial burst of activity subsides (about 5 days later), the moat can dry up and you’ll want to add more water into it. 

Another thing you may notice during fermentation may be a slightly odd odor. This is totally normal! To be honest, some ferments can smell pretty farty. I promise they taste better than they smell! 


9) Refrigerate

When the time is up, remove the air-lock lid, replace it with a regular lid, and move your finished fermented green beans to the fridge. Because of the acidity of fermented foods, standard mason jar lids have the tendency to rust. To avoid this, we store our finished ferments with either these stainless steel lids or these BPA-free plastic ones.

These fermented green beans are good for several months in the fridge, if not longer. We have enjoyed some ferments almost a year after they were made – though we always eat them up quicker than that!


10) Enjoy!

Now it is time to feed your belly with probiotic-rich home-fermented food! We love to use these fermented green beans as a salad topping, or on top of sautéed veggies, brown rice, or curry lentils. They could also be used chopped up in egg salad, on sandwiches, like a pickle on an hor d’oeuvre plate with cheese and crackers, or just snacked on plain! 

Don’t throw out that brine either! The liquid is also chock full of probiotics and beneficial enzymes, just waiting to make your belly happy. Did you know they actually sell leftover ferment brine, marketed as “gut shots”, at natural food stores? And they aren’t cheap! We like to drizzle some on top of salads with olive oil as a dressing, or even take little shots of it straight! 


A fork is holding four fermented beans over the jar. The colors have faded to muted whites and greens in the fermentation process, the liquid brine in the jar below has turned lightish pink in color as well.
Oops! I almost ate the entire jar before remembering to take a “finished” photo to show you! As you can see, the fermented green beans take on a much different color than their raw form! The purple beans we had bled and turned the brine slightly pink.


Ready to ferment?


Go make some insanely healthy, tasty fermented green beans of your own. If you are new to fermenting, do not be nervous! If you follow these steps, it is really quite difficult to “mess up”. In all our years fermenting, we have NEVER had mold or anything dangerous form in a fermenting vessel.

Lacto-Fermented “Pickled” Dilly Green Beans Recipe

Come learn one way to preserve beans – and use this easy recipe to make tangy, crunchy lacto-fermented dilly green bean "pickles"! They are easy to make, downright delicious, and loaded with millions of healthy probiotics, antioxidants, and enzymes to support a healthy digestive system.
Prep Time20 mins
Fermentation Time10 d
Course: Fermented Foods, Preserved Food, Side Dish, Snack
Keyword: Dilly Green beans, Fermented, Fermented green beans, Lacto fermented green beans, Lactofermentation, Pickled Green beans
Servings: 1 quart

Equipment

  • Fermenting vessel, such as a mason jar (pint, quart, or half-gallon)
  • An all-in-one fermentation lid (such as a Kraut Source), or other fermentation weights and an air lock device 

Ingredients

  • organic fresh green beans (as much as you need to completely fill your jar of choice)
  • 1 tbsp kosher or pickling sea salt (not iodized table salt) per 2 cups of water used
  • 2 cups filtered water (per quart jar)
  • 1 bunch fresh dill
  • 1 clove fresh garlic, peeled and lightly crushed (per quart jar)
  • Optional: black peppercorns, red chili flakes, fresh hot chili peppers – if you like them with a kick!

Instructions

  • Wash the green beans. Trim off the stem portion.
  • Either leave the beans whole, or cut them into halves or bite-size pieces. Your choice!
  • In a clean jar or ferment vessel, place a small handful (few sprigs) of washed fresh dill in the bottom of the container. Add optional clove of garlic, pinch of peppercorns or chili flakes.
  • Next, pack the green beans into the container until completely full. Stuff as many as you can close together, minimizing empty air space as you go.
  • On the stovetop on low heat, combine the called-for salt and filtered water to create a salt water brine. Heat only until salt dissolves. Do not add hot brine to the green beans! Allow to cool to room temperature/lukewarm as needed.
  • Pour the brine into the ferment vessel or jar until the green beans are fully submerged. Carefully tap and wiggle the jar side to side to release any trapped air pockets.
  • Next put a Kraut Source lid, or other fermentation weight and air lock lid on top of the jar. Everything needs to stay submerged below the brine!
  • Allow the green beans to sit at room temperature to ferment for Fahrenheit for 7 to 14 days. The ideal fermentation temperature is between 70 and 75 degrees.
  • If you are using a Kraut Source lid, watch the air-lock water "moat" in the lid to ensure it doesn't dry up. Refill with water if needed. Also, carefully remove the top cap of the lid and press the spring down to remove more air halfway through fermentation. Keep the container on a plate to catch overflowing brine.
  • When the time is up, remove air lock lid and weights, cover the container with a standard lid, and store the finished fermented green beans in the refrigerator.
  • Enjoy the fermented dilly green beans for several months, or possibly up to a year. As long as they aren't moldy or obviously putrid, they're still good!

    Hi there!
    So excited to try this! I’ve already got my carrots going. If my beans are a bit on the tougher side, would blanching them first work? What would you suggest?

    Thanks! Love your content.

    • DeannaCat

      Hey there! Sorry for the delay in reply… No, for fermented foods, you don’t want to cook them first (even blanching) because you don’t want to kill the good bacteria! They will soften a bit during fermentation, but obviously won’t eliminate tough strings or whatnot.

  • Natalie

    Hi Deanna! I’m in the south and this growing season my dill was finished long before I had a good crop of beans. Could I use previously frozen dill? Or maybe just buy from the store. Thank you so much for all your great content!!

    • DeannaCat

      Hi Natalie – I think frozen dill should work out just fine! If you have it, might as well use it! Thanks for being here 😉

      • Jennifer

        Hi!
        Love all your stuff! Blog, IG, playlists…Your what I want to be when I grow up! (Even if I am older. Lol)
        Anyways….I live in a colder area and have a basement storage area that runs between 35 and about 55 for most of the year (July/Aug may reach 65-70)…..would this be cool enough to store most fermented things? Beans, Veggies, ACV, etc?
        I need options other than the fridge.
        Thanks!

        • DeannaCat

          Hi Jennifer! Sorry for the delay! I do think that would work in the 35-55 degree range! I think much warmer than that is a little iffy for some things. Finished ACV may be okay (it is vinegar, after all) but the veggies would probably do best around 50 or below. We actually keep our mini ferment fridge around 50 instead of the usual 40′. Yes, we did get an efficient little mini fridge for ferments and kombucha, because I know the struggle for space is real! I hope that helps!
