AIP Sourdough Bread Recipe: Gluten-Free Rise With Tangy Depth

This AIP sourdough bread recipe delivers all the tangy depth and satisfying chew of traditional sourdough without gluten, grains, or dairy. The secret lies in a blend of almond flour, coconut flour, and psyllium husk—creating a structure that rises beautifully while staying compliant with strict dietary needs.

I developed this after years of experimenting with AIP baking, and it finally achieves that perfect balance of airy crumb and crisp crust.

The fermentation process is where the magic happens—just like traditional sourdough, but with a vegan starter made from filtered water and psyllium husk. This creates the signature tang while maintaining a light, fluffy texture.

The bread bakes up golden-brown with a satisfying crunch, proving that AIP baking can be just as rewarding as conventional recipes.

What makes this recipe work is the precise ratio of flours and the careful fermentation timing. No special equipment is needed beyond a loaf pan, and the dough comes together in under 10 minutes.

The result? A gluten-free loaf with the same satisfying pull-apart texture and rich flavor that makes sourdough so beloved.

Perfect for toast, sandwiches, or simply enjoyed with butter (or AIP-compliant alternatives), this bread stays fresh for days when stored properly. The tangy depth comes through in every slice, making it a game-changer for AIP bakers who've missed traditional sourdough.

Precision flours and fermentation create this AIP sourdough’s signature tang and texture without gluten or grains.

The almond flour is non-negotiable—Bob’s Red Mill brand delivers the finest grind for optimal rise. Coconut flour absorbs moisture aggressively, so measure it by weight if possible—spooning leads to overestimation. Psyllium husk powder must be pure; NOW Foods offers a reliable option. For the starter, use filtered water to avoid mineral interference with fermentation. Apple cider vinegar adds tang—raw, unfiltered brands like Bragg contain beneficial enzymes. Store these dry ingredients in airtight containers away from light to preserve freshness for up to 6 months.

No almond flour? Sunflower seed flour works as a 1:1 substitute, though texture will differ slightly. Coconut flour shortages? Tapioca starch at double the amount mimics some binding properties. For the egg replacer, flax eggs (1 tbsp ground flaxseed + 3 tbsp water = 1 egg) create the necessary structure. The coconut milk should be full-fat—canned brands like Thai Kitchen provide the best creaminess. Xanthan gum is critical for gluten-free structure; avoid substitutes as they compromise texture. Pre-mix dry ingredients in a bowl with the salt and baking soda to streamline the process later.

Store the dry flour blend in an airtight container for up to 3 months—the psyllium husk maintains freshness longer than most flours. The starter mixture keeps in the fridge for 5 days if not used immediately, though fresh is always better. Baked loaves stay fresh for 4 days when wrapped in a clean kitchen towel, or freeze for 3 months for long-term storage. For reheating, wrap cooled loaves in foil and warm at 300°F for 10 minutes to restore crispness without drying.

Step-by-step instructions for AIP sourdough bread

AIP sourdough requires precision and patience, but this method delivers a light, tangy loaf with proper rise and texture.

In a medium bowl, combine the 1.5 cups filtered water, 1 tbsp apple cider vinegar, and 0.5 cup melted coconut oil. Stir until fully emulsified—the mixture should look smooth and slightly thickened. The vinegar adds tang while the coconut oil provides moisture and richness.

Next, whisk in the 0.5 cup AIP-compliant egg replacer (flax or chia gel) and 0.25 cup coconut milk (full-fat). The egg replacer mimics the binding properties of traditional eggs, while the coconut milk adds subtle creaminess. Let this mixture sit for 5 minutes to thicken slightly before proceeding.

In a separate large bowl, sift together the 3 cups almond flour, 0.5 cup coconut flour, 0.25 cup psyllium husk powder, 0.25 cup tapioca starch, 1.5 tsp Himalayan pink salt, 0.5 tsp xanthan gum, and 0.5 tsp baking soda. The psyllium husk is critical—it creates structure and elasticity in gluten-free bread.

Make a well in the center of the dry ingredients and pour in the wet mixture. Using a silicone spatula, gently fold until just combined—overmixing develops gluten-like proteins, which we want to avoid. The dough will be thick and sticky, resembling wet sand more than traditional bread dough.

Cover the bowl with a damp towel and let the dough rest at room temperature for 30 minutes. This allows the psyllium husk to hydrate fully and the flours to absorb moisture. The dough should become slightly more pliable but remain cohesive.

After resting, transfer the dough to a lightly oiled baking sheet. Using wet hands, gently shape it into a 9x5-inch loaf pan or freeform boule. Wet hands prevent sticking and help create a smooth surface. Tap the pan gently on the counter to remove any air bubbles.

Cover the shaped dough with a damp towel and let it proof at room temperature for 1.5 to 2 hours, or until it has risen by about 25-30%. The proofing time is critical—too short and the bread will be dense, too long and it may collapse. Look for a slight dome and small cracks on the surface.

Preheat your oven to 350°F while the dough proofs. The oven should be fully heated before baking—this ensures even rise and proper texture. Line a baking sheet with parchment paper for easy removal after baking.

Transfer the proofed dough to the preheated oven and bake for 45-50 minutes, or until the internal temperature reaches 205°F and the top is golden brown. The bread should sound hollow when tapped on the bottom. If the top browns too quickly, tent loosely with foil.

Remove from the oven and let the bread cool on a wire rack for at least 1 hour before slicing. This resting period allows the crumb to set properly. The final loaf should have a crisp crust, a light crumb, and that signature tangy depth from the apple cider vinegar.

Best sauces and condiments for this recipe

Tangy AIP Compotes

Brighten every slice with a strawberry-balsamic compote—simmer 1 cup sliced strawberries, 1 tbsp raw apple cider vinegar, and 1 tbsp coconut sugar for 10 minutes until thickened. The acidity mirrors the bread's tang while adding natural sweetness.

For a savory twist, try a roasted tomato jam with 1 cup diced tomatoes, 1 tsp dried oregano, and ½ tsp sea salt cooked down to a paste. 🍓

Rich Nut Butters

Spread almond butter or sunflower seed butter on warm slices for a protein-packed alternative to traditional butter. I recommend Primal Kitchen almond butter—its smooth texture and mild sweetness complement the bread's depth.

For extra richness, blend ½ cup cashews, 2 tbsp coconut oil, and 1 tsp vanilla extract into a creamy butter. Store in an airtight container for up to 2 weeks.

Herbed Olive Oil

Drizzle herbed olive oil over toasted slices for a Mediterranean-inspired finish. Mix ¼ cup extra-virgin olive oil with 1 tsp dried rosemary, 1 tsp dried thyme, and a pinch of Himalayan pink salt.

Let it infuse for 10 minutes before using. For a spicy kick, add ½ tsp red pepper flakes to the blend. This adds moisture and elevates the bread's natural flavors.

Fermented Condiments

Pair with AIP-compliant fermented condiments like sauerkraut juice or ginger-carrot pickle relish. The probiotics enhance digestion while adding complexity.

For the relish, blend 1 cup shredded carrots, 2 tbsp apple cider vinegar, 1 tbsp grated ginger, and ½ tsp sea salt, then ferment for 3 days. The tangy crunch cuts through the bread's richness beautifully. ✨

Sweet Toppings

Dulce de leche lovers can use coconut milk caramel—simmer 1 can full-fat coconut milk with ¼ cup coconut sugar until thickened. For a lighter option, mash ripe banana slices with 1 tsp cinnamon and warm briefly.

These toppings balance the bread's tang while keeping it AIP-compliant. Store caramel in an airtight container for 1 week.

Savory Spreads

Create a smoky avocado mash by blending 1 ripe avocado, 1 tbsp coconut milk, ½ tsp smoked paprika, and salt to taste. The creaminess contrasts the bread's crisp crust.

For a protein boost, mix 2 tbsp collagen peptides (AIP-approved) into the mash. This spread adds heartiness without overpowering the bread's delicate flavor. 💪
