Sourdough Kimchi Cheddar Biscuits with Green Onion Kimchi

Use up some of that sourdough starter and make these buttery, flaky kimchi cheddar biscuits! Packed with flavor from tangy kimchi and cheddar cheese.

Kimchi Cheddar Biscuits

After you try these sourdough kimchi cheddar biscuits, they’re the only biscuits you’ll ever want! I love eating them as little breakfast sandwiches with eggs and prosciutto.

You have three options for kimchi in this recipe:

  • Homemade Cabbage Kimchi
  • Homemade Green Onion Kimchi
  • Or store-bought kimchi

I obviously recommend homemade kimchi if you have it!

Easy Sourdough Biscuits

These biscuits are simple to make, and you only need about 30 minutes of prep time while your oven preheats to make them.

This is technically a sourdough starter discard recipe, so there is no need for a long rise time or stretch and folds. However, I suggest you still use a fresh, active sourdough starter. A “discard” recipe simply means that you mix the dough, cut, and immediately bake. In discard recipes, the starter is not essential for the rise and texture of the dough.

You get the best texture if you bake these biscuits immediately. You do have the option of long fermenting the biscuits, though.

Overnight Proofing Kimchi Cheddar Biscuits

If you want to, you can make the recipe, cut out the biscuits then place them on a baking sheet and stick them in the fridge for 24-48 hours before baking them. The long fermentation in the fridge develops the flavor and makes them easier to digest.

Ingredients for buttery, flaky sourdough biscuits

  • all-purpose flour ( I used Better Basics Milling Organic Red Fife flour and it’s one of my all time favorite flours to bake with. Use code CULTUREDGURU for 10% off)
  • sugar
  • baking powder
  • sea salt
  • baking soda
  • unsalted butter, frozen overnight
  • active bubbly sourdough starter
  • whole milk
  • heavy cream
  • kimchi, drained (I used my homemade green onion kimchi)
  • cheddar cheese, grated

Can You Freeze Kimchi Cheddar Biscuits?

Yes! You can make them the night before and freeze the raw biscuits.

In the morning, preheat your oven, and they can go right into the oven, still frozen. I like to make a double batch of this recipe to have homemade biscuits ready to serve.

Sourdough Starter For Biscuits

These biscuits’ delicious flavor comes from kimchi, cheddar cheese, and a tangy sourdough starter. Make sure the starter you are using is fresh and not too old. You’re supposed to feed your starter every 24 hours, so your discard should never be older than 24 hours.

For the biscuits to rise and be perfectly flaky, you must follow all the ingredients and instructions exactly. Please make sure you use fresh baking soda, too; it’s essential for the texture.

I also want to note the importance of using frozen real butter, and my favorite butter is Maple Hill Organic 100% grass-fed butter.

You can use a biscuit cutter to cut out the biscuits. Another option is to cut the dough into square biscuits, like what is pictured here.

Sourdough Kimchi Cheddar Biscuits with Green Onion Kimchi

Use up some of that sourdough starter and make these buttery, flaky, delicious kimchi cheddar biscuits! Packed with flavor from tangy kimchi and savory cheddar cheese, these biscuits are sure to be a hit.

  • Prep: 30 minutes
  • Cook: 20 minutes
  • Total Time: 50 minutes

Ingredients

  • 2 1/4 cups all-purpose flour
  • 2 teaspoons sugar
  • 2 teaspoons baking powder
  • 1 teaspoon sea salt
  • 3/4 teaspoon baking soda
  • 1/2 cup unsalted butter, frozen overnight
  • 1/3 cup kimchi, drained and chopped
  • 1/2 cup cheddar cheese, grated
  • 1 cup active bubbly sourdough starter
  • 1/4 cup whole milk
  • 1/4 cup heavy cream

Instructions

  1. Preheat the oven to 450 degrees F.
  2. In a medium bowl, whisk together sourdough starter, cream, and milk until just combined. Let the mixture sit for about 15 minutes while you prepare everything else.
  3. Line a baking sheet with parchment paper.
  4. In a large bowl, combine flour, sugar, baking powder, salt, and baking soda. Mix with a fork until evenly combined.
  5. Grate butter using the large holes of a cheese grater.
  6. Add the cold grated butter, kimchi and cheddar cheese into the flour mixture. Toss to combine.
  7. Add the milk, cream, and starter mixture to the flour mixture and stir with a spatula until a soft dough forms.
  8. In the bowl, knead the dough 2-3 times until it comes together. Don’t knead it too much, but make sure there are no really dry areas and the dough is all stuck together in one piece.
  9. Lightly flour your counter, and using a rolling pin, roll the dough into a thick rectangle.
  10. Cut out 8 rounds using a 2-inch biscuit or cut out 8-9 squares.
  11. Place biscuits onto the prepared baking sheet. Place in the oven and bake for 15 minutes, or until golden brown. I rotate the pan halfway through for even color.
  12. Serve warm.

    I just made these this morning as I had some leftover kimchi I wanted to use up. I split the dough in half and made one batch as just cheddar, and then added the kimchi to the 2nd batch. My family really enjoyed the biscuits both ways, but said the kimchi ones were awesome! I’ll definitely make these again in the future. Thanks for sharing!

And the knife stays in the box. GOOGLE “sourdoug And the knife stays in the box. 

GOOGLE “sourdough king cake” my recipe is the first one! 👑☂️💚✨

If you’re like me and prefer from scratch, homemade everything, you’ll definitely want to try this king cake for Mardi Gras! I used organic naturally dyed sprinkles and all that jazz too. 

If you just search “sourdough king cake” on google you’ll see my recipe, it’s usually the first one. 

My main tips for making this:
✨use a very active starter or throw in some instant yeast with your starter
✨make sure the dough is actually proofed before shaping it. If it’s cold in your house it will take longer. 
✨please follow directions! You can cold ferment the dough in the fridge after it doubles in size and BEFORE filling and shaping.

Fermentation is a gift from the microbes of this e Fermentation is a gift from the microbes of this earth.

When we had a food business, I could never shake the feeling that fermentation is not meant to be sold to you from a fluorescently lit grocery shelf in an endless cycle of waste. Fermentation is meant to be cultivated in your home, with your hands, with intention and love in a sustainable, grateful practice of reciprocity and nourishment. 

This is the story of how we got here. 

After so many lessons learned, our small fermentation business is now value aligned, peaceful, fulfilling, and happy.  It often seems like the gut feelings (the microbes within us) guided us in the right direction. To teach. 

You can learn for free on our blog, or you can enroll in our online courses (we extended our new year sale!) Either way, with me as your teacher, you’ll learn to adopt a holistic perspective on the microbial ecosystems that influence our food, lives, and the planet.
My favorite topic I teach in our online course is My favorite topic I teach in our online course is called Fermentation Variables. The whole lesson is centered around the fact that there are six main variables that influence the outcome of fermentation.

Here they are, in no particular order:

Sugar
Salt
Oxygen
Acidity
Temperature
Time

Temperature and time depend on each other most closely. 

that means, for all of our foods and drinks that ferment at room temp, things slow way down in the winter cold. 

The fermentation timeline is simply longer when it’s colder (and faster when it’s hotter). The microbes, kind of like us, make things happen slowly in the cold winter. 

I think this is yet another sign from nature that we’re supposed to rest and be gentle and gracious with deadlines, work, and not rush things this time of year. 

Let it be slow, it’ll still be great, it just takes a little more patience and time. 

If you’re looking to start fermentation as an analog hobby in the new year, our courses are 40% off right now! You can use code NEWYEARS at checkout. (Yes, you learn online, but it’s delicious, long form content + the skills are life long). What you learn empowers you to get off the computer/phone and go ferment some delicious foods and drinks. 

Touching cabbage and dough is just as good as “touching grass” lol 

Let me know if you have questions about our courses or just fermentation in general in the comments!

Yes cooking kills the microbes, but idc. I mean, I Yes cooking kills the microbes, but idc. I mean, I care, but in a “thank you for your service microbes” kinda way. 🫡

Cider braised pork and sauerkraut is a perfect choice for New Year’s or any winter meal! I lovvveee pairing it with butternut squash polenta bc it’s full of vitamin C for cold and flu szn. 

Eating pork and sauerkraut on New Year’s Day is a tradition. And I really do think it brings good luck and prosperity.

Get the recipe on our blog, linked in my profile and in story highlights! 

I’m really looking forward to creating more recipes like this in the new year, to show you all the joys of incorporating ferments into meals and recipes 😌✨ stay tuned!

For Christmas 2025, I tried something new with these cookies. I created a gingerbread sourdough starter to use in this recipe!
