kcalLow 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.
