Homemade Sourdough Tortillas Fermented Overnight

Soft yet sturdy, these sourdough tortillas are the perfect base for any taco. You only need five ingredients to make these delicious flour tortillas.

Sourdough Tortillas From Scratch

Sourdough tortillas are one of the easiest sourdough things you can make. If you are a beginner sourdough baker, this is a fantastic recipe to start with.

I love that you don’t need to heat your oven to make tortillas. You just need a hot skillet on the stovetop! You can avoid heating up your house with a long oven baking process. So this recipe is perfect for summer tacos.

Also, you don’t have to tend to the dough at all. You mix it, let it rise, then shape and cook. It’s a very hands-off process. I like to mix the dough the evening before I need the tortillas. Then, I let the dough sit at room temperature overnight for about 12 hours.

Tortilla Dough Ingredients

For tortillas, you start with basic sourdough ingredients and add a little olive oil.

If you want to add more flavor to your tortillas, add herbs and spices to the dough. Add a teaspoon of minced garlic for an excellent garlic bread flavor.

Here are all the ingredients you need:

  • 100 grams sourdough starter
  • 175 filtered water
  • 40 grams olive oil, extra virgin
  • 7 grams salt
  • 360 grams unbleached all-purpose flour
12 raw dough balls for making sourdough tortillas.

Shaping the Sourdough Tortillas

Most people think you need a tortilla press to make tortillas, but you can also use a simple rolling pin. A tortilla press will give you more perfect circles. While a rolling pin will give you more variation in the tortilla shape.

First, divide the dough into eight equal pieces and shape the pieces into balls. Then, press the ball slightly on a floured surface to flatten it. Next, roll the dough out using a rolling pin.

Cooking Sourdough Tortillas

You do not bake tortillas like other sourdough bread. Instead, you fry them in a lightly greased hot skillet, and I suggest using a cast iron skillet. Your skillet should be smoking hot, and be sure you baste the dough with a high smoke point fat, like melted butter.

I suggest greasing your skillet with avocado oil or melted tallow and wiping any excess with a paper towel.

Once your skillet is smoking hot, add your flattened-shaped dough to the pan. Once it bubbles up, after about 1 to 2 minutes, flip it and cook for another 1 to 2 minutes.

Storing Tortillas

Once your tortillas are cooked, I suggest storing them in an airtight container with clean paper towels. The paper towels help keep the tortillas from getting too soggy and chewy, while the closed container keeps them soft.

You can warm the tortillas in a skillet again before using them.

Homemade Sourdough Tortillas Fermented Overnight

Soft yet sturdy, these sourdough tortillas are the perfect base for any taco. You only need five ingredients, a rolling pin, and a cast iron skillet to make these delicious flour tortillas.

  • Prep: 10 minutes
  • Cook: 30 minutes
  • Total Time: 8 hours 40 minutes

Ingredients

  • 100 grams sourdough starter
  • 175 filtered water
  • 40 grams olive oil, extra virgin
  • 7 grams salt
  • 360 grams unbleached all-purpose flour

Instructions

  1. Add the sourdough starter, water, oil, salt, and flour to a bowl.
  2. Knead for 2-3 minutes. The ingredients should be fully incorporated, and the dough smooth and slightly elastic.
  3. Place the dough in a greased bowl, cover it with a lid or plate, and allow it to sit at room temperature for 8 to 12  hours.
  4. The next day, divide the dough into 12 equal parts and shape it into little dough balls. Let the balls rest for 30 minutes.
  5. Roll each dough ball out to about a 1/4 inch thickness on a lightly floured work surface. Get them as thin as you can without tearing the dough.
  6. Cook them in a preheated, lightly greased cast iron skillet. One minute on each side should work well.

    Love this recipe. And so simple. Curious if I can you’d SD discard or if it had to be recently fed? Thank you!

    Hello! Wondering how well these last/how you store? I’m hoping to make them Thursday into Friday to use Saturday morning, will they still be pretty good or are these best fresh?

    I’m hoping to make these tomorrow. But was curious if you have ever put any in the freezer? I wanted to make pizza dough and tortillas and freeze them for next time I need them. Thanks

      I’ve only frozen them after cooking! They defrost great in the fridge and I warm them in a pan.

A lot of people think vinegar kills all microbes b A lot of people think vinegar kills all microbes because shelf stable pickles do not contain microbes. But with shelf stable pickles, it’s the pasteurization/sterilization via hot water bath or pressure canning that makes shelf stable pickles free of microbes.

Hot hot hot acid in a pressurized environment does kill, well…most microbes. 

Think about “refrigerator pickle” recipes, though. They need to be stored in the refrigerator because vinegar alone doesn’t stop fermentation.

Fridge pickles are made without pasteurization/sterilization (canning) so they will wild ferment without refrigeration, and not necessarily in a good way because there’s not enough salt. 

All vinegar is made via fermentation too, and vinegar fermentation involves acetic acid bacteria, but also a ton of LAB, mainly Lactobacillus, Pediococcus, and Leuconostoc (the same genera you’d find in fermented veg.)  I linked a reference paper in my fermented mushroom recipe blog, so you all can read about the LAB involved in vinegar fermentation. 

Try 🍄‍🟫googlin’🍄‍🟫“fermented mushrooms” and you’ll see my recipe, it’s the first result (usually) 🤗

I will not ever wild lacto ferment just beets agai I will not ever wild lacto ferment just beets again lol. Mixing with cabbage for beet sauerkraut is the best though! 

“Lacto fermented beets” was the first ferment I tried to make after learning sauerkraut in college. My best friend Sidney came over and we used these gorgeous beets from the farmers market, with 2.5% salt, and some spices. Well, it ended up tasting like beet moonshine and it was just… not good.

But it was a conduit for learning. Those beets were my first lesson in how different sugars and growth in the rhizosphere vs the phyllosphere influences fermentation. 

Cabbage and the cabbage microbiome offer a lot to balance out beets in fermentation, and I think mixing into a sauerkraut is the only way to go for lacto fermenting beets! 

Try googlin’ “beet and red cabbage sauerkraut” and you’ll see my recipe, I’m Cultured Guru.
Squash is the secret ingredient! My Roasted Butte Squash is the secret ingredient!

My Roasted Butternut Squash Hot Sauce recipe is free on my website! I didn’t cook this one, so yes it’s still probiotic.

When lactic acid bacteria ferment the starches in winter squash, they naturally convert them into emulsifying compounds called exopolysaccharides. So when we blend our hot sauce after fermentation, there’s no watery separation in the bottle. Roasting the squash with the garlic for the recipes also adds such good flavor! 

Definitely make sure it’s fully fermented and not bubbling anymore before you blend and bottle. Otherwise, it’ll carbonate in the cute little hot sauce bottles.

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.
