Light, sour, briny, and full of delicious onion flavor. You’re going to love this green onion kimchi inspired fermented relish. Use it anywhere you would use kimchi.

Green Onion Kimchi

Kimchi is usually a spicy mix of fermented cabbage and other ingredients. What kimchi is made of depends on who is making it and where you are trying it!

In Korea, families use local and seasonal ingredients in their kimchi recipes, so there are over 200 types of kimchi, each unique.

One type of kimchi is green onion kimchi, also called Pa-Kimchi. It is made similarly to cabbage-based kimchi, but with green onions as the base.

Fermented Relish

My recipe is inspired by the flavors and ingredients used in pa-kimchi, but it is quite different. If you want to make traditional pa-kimchi check out this recipe from Korean food blogger, Maangchi. Otherwise, stay here and try making my green onion kimchi relish!

Instead of keeping the green onions whole, I like to chop them and mix them with cucumbers for a relish. So this recipe has all the great flavor of green onion kimchi, but it’s easy to incorporate into meals as a relish.

Green Onion Kimchi Relish Ingredients

Here is everything you need to make this recipe:

  • 325 grams green onions, chopped
  • 175 grams cucumbers, minced
  • 10-15 grams Kimchi spice blend (or to taste)*
  • 150 grams filtered water
  • 23 grams unrefined sea salt
chopped green onions and cucumbers in a white bowl with kimchi spices.

Kimchi Spice Blend

This recipe calls for my kimchi spice blend. I blend these spices in bulk and keep them in an airtight jar to easily use the kimchi spice whenever I want to start a new batch.

This is a dry spice blend, and I use organic bulk spices from Starwest Botanicals.

Here is how I make it:

  1. You will need 455 grams gochugaru chili flakes, 300 grams minced garlic, 100 grams ginger powder, and 75 grams kelp granules (all of these are dry ingredients).
  2. Mix the ingredients in a large bowl until evenly combined.
  3. Store in an airtight container, such as a mason jar or weck jar.

Timeline for Green Onion Kimchi Fermented Relish

24 – 48 hours: All contents in the jar should be submerged beneath the brine. At this time, there are still Gram-negative bacteria and possible pathogens present.

48 hours – 5 days: After 48 hours, you should start to see lots of bubbles being produced. This is when the ferment enters stage two of vegetable fermentation. Leuconostoc bacteria begin to thrive, and Gram-negative organisms die off.

5 – 10 days: The bubbles in the brine will decrease as the ferment leaves stage two and enters stage three. The ferment will become cloudy, the color will change, and a pleasant sour smell will develop. You should also recognize onion, garlic, and pepper smells. Lactobacillus species begin to thrive at this time.

10 – 15 days: Next, Lactobacillus make up most or all of the microbial population. They produce copious amounts of lactic acid, making the fermented green onions smell even more pleasantly sour. This is when the relish becomes naturally preserved.

14-21 days: This is when you want to smell and taste test. Wait for the green onion relish to smell and taste as you like, and refrigerate when you find the smell and taste most pleasant! We like ours best when we refrigerate at about 15 days.

Supplies You Need for Fermenting Green Onion Kimchi Relish

For the best sauerkraut flavor and texture, you should use weight measurements for your fermentation ingredients. That means you need a kitchen scale. Weighing your ingredients gives you consistent and superior fermentation results. This is the scale we use in our home kitchen.  

Here is the equipment you will need to make it:

  • Wide Mouth Mason Jar
  • Fermentation Weight
  • Standard Metal Mason Jar Lid (this can rust in the presence of salt)
  • OR Rust-Free Plastic Lid
  • or you can use a Weck Jar (without the gasket; only use the clips to secure the lid)
  • Sea Salt
  • Scale
  • Mixing Bowl

  3. Mince the green onions, tops and bulbs, (removing the roots), and lightly rinse with cool water removing any dirt.

  7. Add the designated amounts green onions, cucumber and spice blend.

  10. Add the salt into the bowl with the green onions and cucumber and mix with your hands until it becomes wet.
  11. Place your empty, clean jar on the scale, and tare/zero the scale. Make sure your scale is still set to grams, and add the designated amount of filtered water to your jar.
  12. Add the water into the bowl with the green onions and cucumber salt. Mix everything well.
  13. Add the entire contents of the bowl into your jar, and pack everything down. (If you have a large cabbage leaf, you can stick that in the top of the jar to help hold all the onion pieces down).
  14. Place your glass fermentation weight in the jar, submerging everything and the weight fully into the liquid.
  15. Secure the lid to the jar.
  16. Ferment for 14-21 days, then refrigerate. Don’t forget to burp the jar daily during the bubbly phase. You can place the jar on a plate to catch any drips.

Thank you so much for this recipe! It turned out amazing! I had to go a little heavier on the cucumber since I didn’t have quite enough green onions on hand, but it still worked out great.
