Cultivating Flavor: A Guide to Homemade Fermented Spinach


Embarking on the journey of fermentation opens up a world of culinary possibilities, and one leafy green that shines in this realm is spinach. Fermenting spinach not only enhances its nutritional profile but also imparts a delightful tangy flavor. In this guide, we’ll explore a simple and delicious recipe for fermented spinach that you can easily make at home.


  • Fresh spinach leaves (organic, if possible)
  • Filtered water
  • Sea salt or non-iodized salt (preferably without anti-caking agents)


  • Clean glass jar with a lid
  • Weights or a small jar that fits inside the larger jar
  • Clean cloth or coffee filter
  • Rubber band or string


  1. Select Fresh Spinach: Start with fresh and preferably organic spinach leaves. Rinse them thoroughly under cold water to remove any dirt or debris.
  2. Prepare the Jar: Clean a glass jar and its lid thoroughly. Sterilize it by running it through the dishwasher or immersing it in boiling water for a few minutes.
  3. Pack the Jar: Pack the cleaned spinach leaves into the jar, leaving some space at the top. You can tear larger leaves into smaller pieces if needed.
  4. Create the Brine: In a separate container, dissolve sea salt or non-iodized salt in filtered water to create a brine. A common ratio is about 1-2 tablespoons of salt per quart of water, but you can adjust according to your taste preference.
  5. Pour Brine Over Spinach: Pour the brine over the packed spinach leaves in the jar, ensuring that the leaves are completely submerged. Leave some space at the top to avoid spillage during the fermentation process.
  6. Use Weights: Place weights or a smaller jar inside the larger jar to keep the spinach submerged beneath the brine. This helps prevent mold growth and ensures an anaerobic environment for fermentation.
  7. Cover and Secure: Cover the jar with a clean cloth or coffee filter and secure it with a rubber band or string. This allows gases to escape during fermentation while preventing contaminants from entering.
  8. Fermentation Time: Place the jar in a cool, dark place and let it ferment for about 1 to 2 weeks. Taste the spinach periodically to check the level of fermentation and stop when it reaches your desired flavor.
  9. Store in the Refrigerator: Once the fermentation process is complete, remove the weights and tightly seal the jar with its lid. Store the fermented spinach in the refrigerator to slow down the fermentation process.
  10. Enjoy Your Fermented Spinach: Use your homemade fermented spinach as a flavorful addition to salads, wraps, sandwiches, or as a side dish. The tangy kick adds a unique twist to your favorite dishes.


Fermenting spinach at home is a rewarding and simple process that elevates this nutritious green to a new level. Experiment with the fermentation time and salt ratios to find the perfect balance that suits your taste buds. With this homemade fermented spinach, you’ll not only enhance the flavor of your meals but also enjoy the probiotic benefits that come with the art of fermentation.
