Low Carb Sourdough Bread Recipe

Ingredients

• 1 ½ cups almond flour

• ½ cup coconut flour

• ¼ cup psyllium husk powder

• 1 tsp baking soda

• 1 tsp sea salt

• 4 large eggs

• 2 tbsp apple cider vinegar

• ½ cup sourdough starter (low carb, made with almond/coconut flour)

• ½ cup warm water

• 2 tbsp olive oil

Directions

• Preheat oven to 350°F (175°C). Line a loaf pan with parchment paper or lightly grease it.
• In a large bowl, combine almond flour, coconut flour, psyllium husk powder, baking soda, and sea salt.
• In another bowl, whisk together the eggs, apple cider vinegar, sourdough starter, warm water, and olive oil until smooth.
• Slowly stir the wet ingredients into the dry mixture until fully combined. The dough will be thick and slightly sticky.
• Transfer the dough to the loaf pan and shape it evenly. Let it rest at room temperature for 1–2 hours to rise slightly (or up to 12 hours for a stronger sourdough flavor).
• Bake for 45–50 minutes, or until the top is golden and a toothpick comes out clean.
• Cool completely on a wire rack before slicing this helps the texture set properly.

Serving Suggestions

• Avocado Toast: Top a toasted slice with smashed avocado, chili flakes, and a drizzle of olive oil.
• Grilled Cheese: Layer with cheddar or mozzarella and grill for a melty, golden low-carb comfort meal.

• Open-Faced Sandwiches: Use as a base for smoked salmon, cream cheese, and cucumber for a refreshing lunch.
• Dipping Companion: Pair with olive oil and balsamic vinegar for a rustic appetizer or side dish.

Storage Suggestions

• Room Temperature: Store sliced bread in an airtight container at room temperature for up to 2 days.
• Refrigeration: Wrap in parchment and keep in the fridge for up to 5 days.
• Freezing: For longer storage, freeze individual slices with parchment between each, sealed in a freezer-safe bag. Toast directly from frozen when ready to eat.
• Avoid Moisture: Always ensure the bread is completely cool before storing to prevent sogginess or mold.
