Ingredients for lacto fermented dilly beans
Seven simple ingredients transform green beans into probiotic-rich dilly beans bursting with tangy, herby flavor—no vinegar needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Green Beans 🌿 | 2 lbs | Trimmed ends, 3-4 inches long |
| Non-Iodized Sea Salt 🧂 | ½ cup | Diamond Crystal preferred |
| Fresh Dill Weeds 🌿 | 1 cup | Packed, stems removed |
| Garlic Cloves 🧄 | 8 cloves | Smashed lightly for flavor |
| Mustard Seeds 🌶️ | 2 tsp | Whole, yellow or brown |
| Black Peppercorns 🌶️ | 1 tsp | Crushed lightly |
| Red Pepper Flakes 🌶️ | 1 tsp | Optional for heat |
| Filtered Water 💧 | 2 cups | Chlorine-free preferred |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed |
| Clean Quart Mason Jars 🍯 | 4 whole | With airtight lids |
| Fermentation Weights 🪨 | 4 whole | Glass or ceramic preferred |
The green beans should be crisp and vibrant—heirloom varieties hold up best during fermentation. Local farmers markets often carry the freshest, or grab the thinnest beans from the grocery store's produce section. Non-iodized salt is critical; Diamond Crystal or Morton kosher work perfectly. For dill, fresh is non-negotiable—dried lacks the bright, herbal punch. If you can't find fresh, dill weed in jars works, but reduce to half the amount. The garlic should be freshly peeled—pre-minced loses flavor fast. Mustard seeds add depth, but skip them if you prefer milder flavor.
No fresh dill? Dried dill at one-third the amount works in a pinch, though texture suffers. Short on garlic? Garlic powder at half the amount is better than nothing. The lemon juice is optional but brightens the flavor—bottled lemon juice works if fresh isn't available. For fermentation weights, sterilized glass jars or even small plates work if you don't have dedicated weights. The brine ratio is key: 1.5% salt solution (2% max) ensures safety while keeping the beans crisp. If your water tastes metallic, chlorine-free filtered water is worth the investment for fermentation.
Store jars at 65-75°F for consistent fermentation—kitchen counters work best. Burp jars daily for the first 3 days to release gases. After 7 days, taste-test: they should be tangy but still crisp. Fridge after 7 days slows fermentation and preserves flavor. These keep for 6-12 months in the fridge, with flavor deepening over time. Label jars with dates—trust me, you'll forget!

Step-by-step instructions for lacto-fermented dilly beans
Here's how to create vibrant, probiotic-rich dilly beans with crisp texture and bright flavor.
Prepare and Pack the Green Beans
Start by trimming the ends from all 2 lbs of fresh green beans, cutting them to 3-4 inches in length. This size ensures they ferment evenly while maintaining their signature crunch. Pack the beans tightly into each of the 4 clean quart mason jars, leaving about 1 inch of headspace at the top. The beans should be standing upright, not overlapping, to allow proper fermentation circulation.
I like to work in batches—pack one jar at a time to avoid crushing the beans. Use a wooden spoon to gently press them down as you go, creating tight layers. This packing method prevents floating and ensures consistent fermentation throughout each jar.
Create the Flavor Brine
In a large bowl, combine 2 cups of filtered water with 0.5 cup of non-iodized sea salt. Stir until the salt completely dissolves—this creates the brine that will preserve and flavor your beans. The solution should taste noticeably salty, like the sea, but not overwhelming.
Next, add 1 cup of fresh dill weeds (stems removed), 8 smashed garlic cloves, 2 tsp of mustard seeds, 1 tsp of crushed black peppercorns, 1 tsp of red pepper flakes, and 2 tbsp of freshly squeezed lemon juice. Mix thoroughly to distribute all the aromatics. This blend of herbs and spices will infuse the beans with complex, tangy flavor during fermentation.
Fill Jars and Add Weights
Pour the brine mixture over the packed beans in each jar until they're completely submerged, leaving that 1-inch headspace. Tap the jars gently on the counter to release any air bubbles trapped between the beans. Use a clean chopstick or skewer to push down any beans that float to the surface—this ensures they stay fully submerged and ferment properly.
Place a fermentation weight on top of the beans in each jar. These weights keep the vegetables submerged and prevent mold growth. The weights should sit comfortably above the bean level, not pressing down too hard. Wipe the jar rims with a clean, damp cloth to remove any brine residue that could prevent proper sealing.
Seal and Ferment at Room Temperature
Screw the lids onto the jars finger-tight—don't overtighten, as the jars need to vent gases during fermentation. Place the jars in a dark, cool spot (around 68-72°F) where they won't be disturbed. Over the next 3-5 days, you'll see bubbles forming in the brine and hear occasional popping sounds—this is normal fermentation activity.
After 5 days, taste a bean to check for tanginess. If it's ready (bright, slightly sour, and crisp), transfer the jars to the refrigerator to slow fermentation. If not, let them continue fermenting for 1-2 more days, checking daily. The beans should develop a vibrant green color and develop that classic dilly bean tang.
Store and Enjoy Your Fermented Beans
Once properly fermented, remove the weights and store the sealed jars in the refrigerator. The cold temperature preserves the flavor and probiotics while maintaining the beans' crisp texture. Your dilly beans will keep in the fridge for 3-6 months, with flavor continuing to develop over time.
To serve, simply open a jar and scoop out the beans. They're perfect as a tangy snack, on charcuterie boards, or as a bright topping for salads and sandwiches. The probiotic-rich brine makes them a gut-friendly addition to any meal—just be sure to consume them within the recommended timeframe for maximum freshness and potency.
Pro Tips For Making Lacto Fermented Dilly Beans
- Trim the Beans Properly: Cut the ends cleanly but leave the stems intact—this keeps the beans from turning mushy during fermentation. I used to snip too close, and they’d bruise like overripe fruit. A sharp knife and a steady hand make all the difference.
- Salt in Layers: Pack the jar with beans, sprinkle a thin layer of salt, then repeat. This ensures even distribution without over-salting the top layers. I learned this the hard way when my first batch tasted like the ocean at the bottom and bland at the top.
- Crush, Don’t Mince, Garlic: Smash the garlic cloves flat with the side of your knife—this releases more flavor than mincing while keeping it whole enough to stay in place. Over-mincing turns it into garlic paste, which sinks and pools instead of mingling evenly.
- Weigh Down the Beans: Use a fermentation weight (or a smaller jar filled with water) to keep the beans submerged. If they float, mold grows on the exposed parts. I skipped this once and came back to a jar of sad, fuzzy beans—don’t let that happen to you.
Storing and reheating your lacto fermented dilly beans
Refrigerator Storage
Once your dilly beans reach the perfect tangy crunch at 7 days, transfer them to the refrigerator to halt fermentation and preserve their probiotic benefits. Store sealed jars in the fridge at 40°F or below—this slows bacterial activity while maintaining crisp texture.
I keep mine on the middle shelf where temperatures stay consistent. The beans will continue developing flavor over 3-6 months, becoming even more complex with time. 💫
Freezer Preservation
For longer storage beyond 6 months, portion your fermented beans into freezer-safe bags or airtight containers. Remove as much brine as possible to prevent ice crystals from dulling the texture. Label each bag with the date—these freeze beautifully for up to 12 months.
When ready to use, thaw overnight in the fridge and enjoy within 3-5 days for best quality. I recommend using a vacuum sealer for maximum freshness.
Reheating Tips
Fermented beans don't need reheating, but if you want to warm them slightly for serving, place the jar in a bowl of 110°F water for 10-15 minutes. This gentle method preserves their crunch and flavor.
Avoid microwave reheating—it can turn the beans mushy. For best results, serve them straight from the fridge alongside grilled meats or in summer salads where their tangy brightness shines. 🌿
Safety First
Always check for proper sealing before storing—look for a slight vacuum seal or "pop" when opening. If the jar doesn't seal properly, transfer the beans to a clean container with fresh brine and refrigerate immediately.
Discard any beans that develop an off odor, slimy texture, or mold. I've never had issues following these steps, but proper hygiene (clean jars, sterile tools) is your first line of defense against spoilage. 🧼
Flavor Boosting
Want to enhance stored beans? Add a pinch of smoked paprika or fresh dill when serving to revive their brightness. For extra zing, mix a splash of the reserved brine with a little apple cider vinegar (1:1 ratio) and drizzle over the top.
These tricks work wonders on beans that have been stored for months. The key is keeping them submerged in their flavorful brine—never rinse them before eating! 💡
Serving Suggestions
Use your stored dilly beans in creative ways beyond simple snacks. Chop them into ½-inch slices for charcuterie boards, mix into grain bowls with quinoa and avocado, or layer them in sandwiches alongside smoked salmon.
The probiotic-rich brine pairs beautifully with rich cheeses or cured meats. I love serving them chilled as a palate cleanser before spicy dishes—they're a game-changer for any meal! 🍽️

Frequently asked questions
Why should I use non-iodized salt for fermenting?
Iodized salt can introduce unwanted bacteria and interfere with the fermentation process. Non-iodized sea salt like Diamond Crystal creates the ideal 1.5% salt solution for safe, flavorful fermentation while preserving the beans' natural crunch. The salt level is crucial—too little risks spoilage, while too much makes the beans mushy.
Can I use dried dill instead of fresh?
Fresh dill is best for vibrant flavor, but you can substitute ⅓ cup dried dill if needed. The texture won't be as bright, but it'll still add that classic herby note. For extra depth, add a pinch of dried dill weed (not seeds) to your brine—it mimics fresh dill's aroma better than whole dried dill.
What if my beans float to the top during fermentation?
Floating beans are normal, but they need to stay submerged to ferment properly. Use a clean chopstick to gently push them down, or add a fermentation weight if needed. If bubbles form and push beans up again, check your salt level—too little salt can cause excessive gas production. The beans should remain covered by at least 1 inch of brine.
How do I know when the fermentation is complete?
After 5-7 days, taste a bean—it should be tangy, slightly sour, and still crisp. The brine may turn cloudy, and you'll smell a pleasant, slightly sour aroma. If the flavor is too mild, ferment 1-2 more days. Once ready, refrigerate immediately to halt fermentation and lock in flavor.
Can I make this recipe without garlic?
Yes! Replace the 8 garlic cloves with 1 tsp garlic powder (or 2 tsp granulated garlic) for a milder flavor. For extra depth, add a pinch of onion powder to mimic garlic's savory notes. The mustard seeds and dill will still provide that classic "dilly" taste, just with a less pronounced punch.
