Keto Sourdough Bread: A Low Carb Dream Come True

Sourdough starter in jar with bubbly fermentation.

Okay, I’m just going to say it—if you’re missing bread on a keto diet, you’re not alone. I totally get it. There’s just something about the smell of freshly baked sourdough, the crispy crust, and the soft, chewy center that feels universally comforting. But here’s the kicker—traditional sourdough bread won’t exactly fit your low-carb goals. Luckily, there’s good news—hello, keto sourdough bread!

This recipe is for anyone who refuses to give up bread, loves to experiment in the kitchen, or just wants to try something tasty (and yes, relatively healthy). I’ll walk you through everything: what makes keto-friendly bread work, why sourdough is worth the effort, and how easy it is to recreate that crusty bakery magic at home without ruining your daily carb count.

Here’s the thing—if you know me, you know I’m obsessed with food that’s delicious but still meets lifestyle goals. Keto sourdough bread checks both boxes. Come on, let’s talk all things about this game-changer for sourdough and low-carb enthusiasts alike!

Why I Fell in Love With Keto Sourdough Bread

Before diving into all the how-to details, let’s chat about why this bread isn’t just hype. I started eating keto when I needed to rein in my blood sugar swings (it’s a whole story involving way too much soda and a relentless sweet tooth). Cutting carbs helped, but I missed bread hard. Like capital-H Hard.

One day, during a random rabbit hole on the internet, I started reading about sourdough fermentation. Traditional sourdough is cool because it breaks down some of the carbs into easier-to-digest sugars. That got me thinking, what if I could keto-ify this process altogether? Enter this genius bread recipe!

The other thing I love about this recipe? It brings back the ritual of baking. If you’ve ever felt the satisfaction of kneading dough or smelling yeast, you know what I mean. And if you haven’t, trust me, you’re in for a treat (or at least a relaxing new hobby).

What Makes Keto Sourdough Bread So Special?

Let’s get real here—making keto sourdough bread takes more than just swapping white flour for almond flour. There’s a delicate science behind creating bread that’s low carb but still chewy, flavorful, and structurally sound. (Nobody wants to bite into a dry, crumbly loaf that tastes like cardboard!)

So what’s the secret sauce? It’s a combination of:

  • Low carb flours (like almond and coconut flour) to keep things keto-approved.
  • Psyllium husk and vital wheat gluten (more on this later) to mimic that bready texture.
  • A sourdough starter made with keto-friendly ingredients to ferment and give that tangy flavor.

And here’s a fun fact: Many people don’t realize that sourdough fermentation can cut down carb counts even further. That’s a big win for anyone tracking macros while still craving carbs.

Recipe Time: Let’s Bake Keto Sourdough Bread!

Mixing the wet ingredients into dry ingredients for keto sourdough dough.

Making keto sourdough bread isn’t hard, but it does take a little patience. I promise it’s worth it, though. First, let me break down what you’ll need.

Ingredients

For the Sourdough Starter:

  • 1 cup (96g) almond flour
  • 1/4 cup (24g) coconut flour
  • 1/2 teaspoon sugar (don’t freak out—this feeds the yeast and gets mostly “eaten” in the fermentation process!)
  • 1/3 cup warm water
  • 1/4 teaspoon active dry yeast

For the Dough:

  • 2 cups (192g) almond flour
  • 3 tablespoons (45g) coconut flour
  • 2 tablespoons (14g) psyllium husk powder
  • 1 tablespoon (12g) vital wheat gluten (optional but amazing for structure!)
  • 1/2 teaspoon salt
  • 2 large eggs
  • 1/4 cup (60ml) warm water
  • 1/4 cup (60ml) olive oil
  • 1/2 cup sourdough starter (from above)

Tools You’ll Need

  • A small jar or bowl for the starter
  • A mixing bowl
  • Parchment paper
  • A Dutch oven or baking stone (for that perfect crust)
  • Measuring cups and spoons (don’t eyeball this one!)

Directions

  1. Make Your Starter

Combine almond flour, coconut flour, sugar, warm water, and yeast in a small jar. Mix well, then cover loosely with cheesecloth or a lid. Let it sit at room temperature for 24–48 hours. (You’ll know it’s ready when it’s bubbly and smells tangy.)

  1. Mix The Dry Ingredients

In a large bowl, stir together almond flour, coconut flour, psyllium husk, vital wheat gluten, and salt.

  1. Combine Wet Ingredients

Beat the eggs in a separate bowl, then add warm water, olive oil, and 1/2 cup of your sourdough starter. Mix everything until smooth.

  1. Bring It All Together

Slowly add the wet mixture into the dry ingredients. Stir until it forms a soft dough. If it feels too sticky, add a little more almond flour (but don’t overdo it!).

  1. Shape and Proof

Form the dough into a round loaf and place it on parchment paper. Cover with a clean kitchen towel and let it rise for 2–3 hours.

  1. Bake It Up

Preheat your oven to 375°F. Place your baking stone or Dutch oven inside to preheat as well. Once hot, bake the bread for 40–50 minutes, until golden brown and crusty.

  1. Cool Down

As tempting as it is, let the bread cool completely before slicing. This step is key for the texture to set!

Frequently Asked Questions

Shaping and proofing keto sourdough dough on parchment paper.

Is sourdough bread okay on a keto diet?

Regular sourdough bread isn’t okay for strict keto, but a low-carb version like keto sourdough bread can definitely work. The trick is using almond flour, coconut flour, and other keto-friendly substitutes to hit those macros. Plus, fermenting helps lower the remaining carbs!

Can you use almond flour when making sourdough bread?

Absolutely! Almond flour is a staple in keto sourdough bread. It’s low in carbs, naturally gluten-free, and has a mild taste that works well with sourdough’s tangy flavor. Just make sure to pair it with other ingredients that add structure, like psyllium husk or vital wheat gluten.

What is the healthiest bread for keto?

Low carb sourdough bread is a top contender! It’s packed with fiber, low in net carbs, and has that fermented tang you don’t usually get from other keto bread options. Bonus: It’s homemade, so you control all the ingredients.

Is sourdough bread an unhealthy carb?

Traditional sourdough bread can be high in carbs, but it’s not necessarily “unhealthy.” For keto folks, though, regular sourdough isn’t ideal. That’s why keto sourdough bread exists—to give you the same vibe without the carb overload.

Real Talk: Is Keto Sourdough Bread Worth the Effort?

I think so. The flavor, texture, and satisfaction of homemade bread just hit differently, you know? Plus, baking something you love (that’s still keto-compliant) is honestly kind of empowering. If you’ve ever made your own bread, you know it’s less about perfection and more about the process. Keto sourdough bread isn’t just bread—it’s a reminder that you really can have it all.

So, grab your mixing bowls, get your starter bubbling, and dive in. Your taste buds—and your macros—will thank you!
