There’s something truly magical about making your own fermented pickles at home. Not only are they absolutely delicious—crispy, tangy, and bursting with flavor—but they’re also packed with probiotics that are fantastic for your gut health. I’ve been making fermented pickles for years now, and I can honestly say that once you taste a homemade fermented pickle, you’ll never go back to the store-bought versions.
The beauty of fermentation is that it’s surprisingly simple. You don’t need any special equipment or fancy ingredients—just cucumbers, salt, water, and a few aromatics like dill, garlic, and peppercorns. The magic happens naturally as beneficial bacteria work their way through your brine, creating that distinctive tangy flavor and probiotic-rich environment that makes fermented pickles so special.
What I love most about this recipe is how customizable it is. Whether you prefer your pickles spicy with red pepper flakes, herbaceous with fresh dill and tarragon, or classic with just garlic and peppercorns, you can adjust the flavors to match your preferences perfectly. Plus, fermented pickles last for months in your refrigerator, making them the perfect make-ahead project.
I’ve shared my fermented hot sauce recipe with many friends who were intimidated by fermentation, and I want to do the same with pickles. Once you understand the basic principles, you’ll realize how easy and rewarding this process truly is.

The key to success is maintaining the right salt-to-water ratio and keeping your cucumbers submerged throughout the fermentation process. I also recommend checking out Serious Eats’ detailed fermentation science to understand the chemistry behind it all. For troubleshooting and advanced techniques, Bon Appétit’s pickle guide is incredibly helpful.

Ingredients
- 2 pounds small to medium Kirby cucumbers (about 3-4 inches long), washed and dried
- 2 tablespoons sea salt or pickling salt (non-iodized)
- 2 cups filtered or dechlorinated water
- 4 cloves fresh garlic, peeled and lightly smashed
- 2 tablespoons fresh dill (or 1 tablespoon dried dill)
- 1 teaspoon black peppercorns
- ½ teaspoon red pepper flakes (optional, for heat)
- 4-5 fresh grape leaves or oak leaves (optional, helps keep pickles crisp)
- 2-3 bay leaves
- ½ teaspoon coriander seeds (optional)
- 1 small piece fresh horseradish root, sliced (optional, for extra crunch)
- 2-3 fresh thyme sprigs (optional)
Instructions
- Prepare your jar by washing it thoroughly with hot soapy water, then rinsing well with hot water. A clean quart-sized glass jar works perfectly for this recipe.
- Cut off the blossom end (the opposite end from the stem) of each cucumber using a sharp knife—this contains enzymes that can make pickles mushy during fermentation.
- In a small bowl, whisk together the salt and filtered water until the salt is completely dissolved. Stir well and set aside.
- Add the garlic cloves, fresh dill, peppercorns, bay leaves, coriander seeds, and any other desired aromatics to the bottom of your clean jar.
- If using grape or oak leaves, add them now—these leaves contain tannins that help keep your pickles crispy and crunchy throughout fermentation.
- Begin packing the cucumbers into the jar vertically, arranging them as tightly as possible without crushing them. They should stand upright and fill the jar snugly.
- Pour the prepared salt brine over the cucumbers, making sure they are completely submerged. The brine should cover them by at least one inch.
- Insert a small glass weight, clean fermentation weight, or even a small glass jar filled with water on top of the cucumbers to keep them submerged below the brine level.
- Place the jar on a plate or small tray to catch any brine that may overflow during fermentation.
- Cover the jar with a clean kitchen towel, coffee filter, or cheesecloth secured with a rubber band—you want to keep dust and insects out while allowing gases to escape.
- Place the jar in a cool, dark location away from direct sunlight. A pantry, kitchen cabinet, or basement shelf works perfectly. Ideal temperature is between 65-75°F.
- Check your pickles daily, looking for signs of fermentation. Within 1-2 days, you should see bubbles forming and the brine becoming slightly cloudy.
- If white mold appears on the surface, simply skim it off with a clean spoon—this is normal and harmless. If the mold is fuzzy or colored, discard the batch.
- Taste your pickles on day 3 to check the fermentation progress. They should taste slightly sour and crisp.
- Continue tasting daily until they reach your desired level of sourness and tang. Most pickles are perfect between days 5-7 of fermentation.
- Once they taste just right, remove the weight and cover the jar with a proper lid or plastic wrap.
- Store your finished fermented pickles in the refrigerator, where they will continue to slowly ferment but at a much slower rate.
- Your fermented pickles will keep for several months in the refrigerator, with flavors continuing to develop and deepen over time.
Pro Tips
- **Cucumber Selection**: Choose small to medium Kirby cucumbers or pickling cucumbers for the best results. Avoid large slicing cucumbers as they tend to become hollow and mushy during fermentation.
- **Salt Importance**: Use non-iodized salt like sea salt or pickling salt. Iodized table salt can cloud your brine and interfere with fermentation. The salt is crucial—it creates an environment where beneficial bacteria thrive while harmful bacteria cannot.
- **Water Quality**: If your tap water is heavily chlorinated, use filtered water instead. Chlorine can inhibit fermentation by killing the beneficial bacteria you want to cultivate.
- **Temperature Control**: Fermentation happens best between 65-75°F. Cooler temperatures slow fermentation (which is fine, it just takes longer), while temperatures above 75°F can speed it up but may result in softer pickles. Avoid temperature fluctuations.
- **Keeping Pickles Submerged**: This is critical. Cucumbers exposed to air can develop mold or become soft. Use fermentation weights, a small jar filled with water, or even a cabbage leaf weighted down with a glass.
- **Customization Ideas**: Add fresh turmeric for earthy flavor, mustard seeds for a slightly spicy note, or sliced jalapeños for heat. Try different combinations of fresh herbs like tarragon, oregano, or basil.
- **Fermentation Timeline**: Days 1-2: Initial fermentation begins, mild flavor. Days 3-4: Pronounced sourness developing. Days 5-7: Full tangy flavor, perfect crispness. After day 7: Increasingly sour and soft.
- **Troubleshooting Soft Pickles**: Soften pickles usually result from mold exposure, warm temperatures, or missing the blossom end removal. Ensure cucumbers are fresh, remove the blossom end, and keep them fully submerged.
- **Cloudy Brine**: Don’t worry! This cloudiness is normal and indicates active fermentation. It’s just yeast and beneficial bacteria doing their job.
- **Storage Tips**: Once fermented to your liking, refrigerate to slow fermentation. They’ll keep for 3-6 months in the fridge, though flavor will continue evolving. Save the brine to start a new batch—it already contains beneficial bacteria!
- **Probiotic Benefits**: Fermented pickles contain beneficial lactobacillus and other probiotics that support gut health. These live cultures survive refrigeration but die if you heat-process the pickles.
- **Make-Ahead Friendly**: These are perfect for meal prep. Keep a jar in your fridge for snacking, serving alongside sandwiches, or chopping into relishes and salads.
