If you don’t love radishes, this recipe just might change your mind! Fermenting radishes takes some of the “bite” out of their flavor, replacing it with a crunchy, salty, slightly sour tang. My kids call them “radish pickles” and have been known to ask for second and third helpings . . . seriously!

They make a great addition to salads and charcuterie boards, and they can also be used as “chips” for things like hummus or ranch dressing.

Also, thanks to a process called lacto-fermentation, they’re rich in gut-friendly probiotics. Here’s how it works:

  1. Put veggies in a clean vessel.
  2. Add a saltwater brine to the vessel and seal it.
  3. Let the magic unfold.

By magic, I mean that lactobacillus bacteria – which are naturally present in veggies – are tolerant to saltwater, while most bad guys can’t take much of it. When we place veggies in a saltwater brine it gives the good guys the advantage, allowing them convert sugar and starches into lactic acid.

Other Benefits

Lactic acid is also helpful for:

  • Improving the flavor profile (adding tartness/sourness)
  • Extending the shelf life (lactic acid fermentation was one of the primary methods used to preserve foods for generations)
  • Breaking down digestion inhibitors (oxalates and phytates) so that nutrients are more bioavailable. (1)

As a byproduct of fermentation, lactobacillus bacteria can also produce additional nutrients like vitamin K2, which are not naturally present in veggies. (2) So, in a nutshell, you get flavor, probiotics, improved digestibility, and additional vitamins.

What You’ll Need

To get started, you’ll need to gather your ingredients and some basic equipment like a wide-mouth quart jar and:

Also, if your bunch came with the radish greens attached, don’t toss them – try this pesto recipe. Now let’s get to the recipe!

  • quart-size mason jar
  • Fermentation weight*
  • fermentation lid with airlock (optional)


  • 3 cups sliced fresh radishes
  • 2-3 whole garlic cloves (peeled)
  • 3.5 tsp sea salt (non-iodized)
  • 4 cups filtered water


  • Thoroughly clean your mason jar, lid, and cutting before getting started.
  • Boil the water for five minutes, then measure out 3.5 cups of water and stir in the salt until it dissolves. Allow the brine to cool to room temperature.
  • Place the peeled garlic cloves in the mason jar.
  • Slice the radishes thinly and pack them into the fermenting jar, leaving about 1.5 inches of headspace between the top of the radishes and the lid.
  • Pour the room temperature salt brine over the radishes until they are completely covered, leaving at least one inch of headspace between the top of the brine and the lid.
  • Place a weight inside the mouth of the jar to keep your radishes under the brine. Place the lid on the jar and set up the airlock if you’re using one.
  • Allow the jar to ferment at room temperature for 3-5 days, depending on how tangy you want them to be. Keep it out of direct sunlight – I keep mine in a shady area of my kitchen or one of my kitchen cabinets. Taste your fermented radishes starting on day 3, and when it reaches a flavor that you like transfer it to the fridge. If you're using a lid with an airlock, replace it with a regular mason jar lid before storing it.


Since the time can vary based on several factors, the prep time estimate does not include the step of boiling and cooling the brine.
If you’re using a regular lid (no airlock) you will need to “burp” your jars periodically, otherwise carbon dioxide levels can build up within your jar and cause it to explode. Check the metal lid every day – if you can’t push it down simply unscrew the lit a bit and then immediately tighten it back down. Using an airlock which allows the gases to release eliminates the need to burp your jars.
