PosKeto Sourdough Focaccia offers a soft, airy texture with a golden crust while keeping carbohydrate content far lower than traditional wheat-based focaccia. The sourdough element brings a gentle tang and deeper flavor, creating a bread that works beautifully as a side dish, sandwich base, or snack.

Preparing the Keto Sourdough Starter
A keto sourdough starter may be created using almond flour and water. Feed the starter regularly until active and bubbly. A mature starter should have a pleasant aroma and visible bubbles throughout.
Before making focaccia, feed the starter several hours ahead so peak activity occurs during dough preparation.
Mixing the Dry Components
Place almond flour, coconut flour, psyllium husk powder, baking powder, and sea salt into a large bowl.
Whisk thoroughly. Proper blending prevents clumps and helps distribute the ingredients evenly. The psyllium husk plays a major role by helping hold moisture and providing elasticity.
Continue whisking until the mixture appears uniform.
Mixing the Wet Components
In a separate bowl combine:
- Active keto sourdough starter
- Eggs
- Olive oil
- Warm water
- Apple cider vinegar
Whisk until smooth and fully blended.
The warm water helps activate fermentation while creating a softer dough consistency.
Forming the Dough
Gradually pour the wet mixture into the dry ingredients.
Stir with a spatula until a thick dough develops.
Allow the dough to rest for approximately 5 minutes.
During this period the psyllium absorbs liquid and transforms the mixture into a more workable consistency.
After resting, gently fold the dough several times.
The dough should feel soft, slightly sticky, and cohesive.
Fermentation Stage
Transfer dough into a lightly oiled bowl.
Cover with a clean towel or plastic wrap.
Place in a warm location for 4–8 hours.
During fermentation:
- Flavor develops further.
- Texture improves.
- Mild sourdough notes become more noticeable.
- Moisture distributes evenly.
The dough may not double dramatically like traditional wheat dough, yet slight expansion and a lighter appearance should occur.
Pan Preparation
Line a baking pan with parchment paper.
Drizzle a small amount of olive oil over the surface.
Transfer fermented dough into the pan.
Using lightly oiled hands, gently press dough toward all corners.
Aim for an even thickness throughout.
Allow dough to rest for an additional 20–30 minutes.
Creating the Classic Focaccia Surface
Coat fingertips with olive oil.
Press small dimples across the entire surface.
These dimples help trap olive oil and toppings while creating the traditional focaccia appearance.
Take care not to flatten the dough excessively.
Adding Toppings
Drizzle olive oil generously over the surface.
Sprinkle:
- Rosemary
- Oregano
- Thyme
- Flaky sea salt
Additional toppings may also be added at this stage.
For extra flavor, tuck roasted garlic cloves into several dimples.
Baking Instructions
Preheat oven to 375°F (190°C).
Place pan onto the center rack.
Bake for approximately 30–35 minutes.
Signs of readiness include:
- Golden brown top
- Firm edges
- Pleasant roasted aroma
- Slightly crisp exterior
A thermometer inserted into the center should read approximately 200°F (93°C).
Cooling Process
Remove pan from oven.
Allow bread to cool within the pan for 10 minutes.
Transfer to a cooling rack.
Cool completely before slicing.
Cooling helps the crumb finish setting and prevents excessive crumbling.

- Golden crust
- Tender center
- Moist crumb
- Gentle chew
