Keto Sourdough Bread Recipe: A Low-Carb Classic Favorite

Sourdough bread has long been loved for its tangy flavor, chewy texture, and comforting tradition. Unfortunately, traditional sourdough bread is very high in carbohydrates, which puts it off-limits for most keto lifestyles. The good news? With a few smart ingredient swaps, you can still enjoy sourdough-style bread while staying true to your low-carb goals.

This keto sourdough bread recipe uses low-carb flours and a keto-adapted sourdough starter to recreate that classic flavor and texture without the carb overload. It’s satisfying, nourishing, and surprisingly easy to make at home.

Keto sourdough bread replaces wheat flour with a combination of fine blanched almond flour, coconut flour, and psyllium husk powder. This combination provides structure, fiber, and that familiar bread-like consistency while keeping carbs low.

Ingredients You Will Need

2 cups fine blanched almond flour (important for a smooth texture — avoid coarse almond meal)

1/2 cup coconut flour

1/4 cup psyllium husk powder

1 teaspoon baking powder

1 teaspoon salt

4 large eggs

1/4 cup olive oil or melted butter

1/4 cup water

1/4 cup keto sourdough starter (see my keto starter guide)

Optional toppings:

Sesame seeds, hemp seeds, sliced almonds, sunflower seeds, or poppy seeds.

Instructions

Preheat Your Oven

Preheat your oven to 350°F (175°C). Grease a loaf pan with butter or line it with parchment paper.

Mix Dry Ingredients

In a large bowl, combine the almond flour, coconut flour, psyllium husk powder, baking powder, and salt. Mix thoroughly so everything is evenly distributed.

Mix Wet Ingredients

In a separate bowl, whisk together the eggs, olive oil (or melted butter), water, and keto sourdough starter until smooth.

Combine

Pour the wet mixture into the dry ingredients and stir until a thick, sticky dough forms. Let it sit for a few minutes so the psyllium husk can absorb moisture and firm up the dough.

Shape the Dough

Transfer the dough into your prepared loaf pan. Smooth the top with a spatula or damp hands. Sprinkle seeds on top if desired.

Bake

Bake for 50–60 minutes, or until golden brown and the loaf sounds hollow when tapped.

Cool Completely

Allow the bread to cool in the pan for about 10–15 minutes, then transfer to a wire rack. Cooling fully improves texture and slicing.

Tips for Success

Always Use Fine Blanched Almond Flour

This is key. Fine blanched almond flour produces a softer crumb and better rise. Almond meal or coarse flour can make the bread dense or gritty.

Check Dough Texture

The dough should be thick and sticky. Add a little water if dry, or a touch more almond flour if too wet.

Give It Time

Keto sourdough behaves differently from wheat bread. Fermentation and baking times can vary slightly, so patience helps.

How to Enjoy Keto Sourdough Bread

Once cooled, slice and enjoy:

Toasted with butter or olive oil

Spread with avocado or nut butter

Made into sandwiches

Served with soups or salads

As a breakfast toast alternative

It’s hearty, satisfying, and keeps beautifully.

Keto sourdough bread is a fantastic way to enjoy the tradition of sourdough while maintaining ketosis and stable blood sugar levels.

Is Keto Sourdough Bread Prebiotic or Probiotic?

Interestingly, keto sourdough bread may offer both benefits.

Prebiotic Benefits

Psyllium Husk Fiber

Psyllium husk is rich in soluble fiber that feeds beneficial gut bacteria.

Almond and Coconut Flour Fiber

These flours provide additional non-digestible fiber that supports gut microbiome balance.

Probiotic Benefits

Sourdough Starter Cultures

A keto sourdough starter contains wild yeast and lactic acid bacteria. During fermentation, these organisms create beneficial acids and compounds associated with gut health.

While baking reduces live bacteria somewhat, fermentation still contributes digestive benefits.

Keto sourdough bread offers a delicious low-carb alternative that supports both metabolic health and gut health. It allows you to enjoy the tradition of sourdough while staying aligned with your keto lifestyle.
