Side Dishes
This AIP sourdough bread recipe delivers a crusty, open-crumbed loaf that meets strict autoimmune protocol requirements—no gluten, dairy, eggs, or traditional yeast. The secret lies in a fermented almond flour starter that creates that signature tang and airy texture without compromising dietary needs.
After years of perfecting this method, I’ve finally cracked the code for a bread that rivals artisanal loaves while staying completely compliant.
The process begins with a 3-day fermentation period to develop flavor and structure, using only AIP-approved ingredients like almond flour, coconut oil, and apple cider vinegar.
Unlike traditional sourdough, this version relies on a wild fermentation that’s gentle yet effective, producing a loaf with a golden crust and an open, shatteringly crisp crumb. The key is patience—letting the dough rise slowly at room temperature before a final proof in the fridge.
What makes this recipe work is the balance of moisture and structure, which can be tricky in AIP baking. The almond flour provides protein for elasticity, while the coconut oil adds richness without dairy.
By the time it emerges from the oven, you’ll have a fragrant, hearty loaf that’s perfect for sandwiches, toast, or serving alongside soups—all while supporting an elimination diet.
This method also includes troubleshooting tips for common AIP baking challenges, like preventing a dense crumb or ensuring proper rise. With the right technique, you’ll achieve restaurant-quality results at home, proving that dietary restrictions don’t mean sacrificing flavor or texture. Let’s get started on your first compliant loaf.
Ingredients for aip sourdough bread
Precision ingredients for a compliant yet artisanal AIP sourdough loaf—no shortcuts, just science-backed baking.
| Ingredient | Amount | Notes |
|---|---|---|
| Almond Flour 🌰 | 3 ½ cups | Finely ground, blanched preferred |
| Coconut Oil 🥥 | ½ cup | Melted, unrefined for flavor |
| Apple Cider Vinegar 🍎 | ¼ cup | Raw, unfiltered preferred |
| Filtered Water 💧 | 1 ½ cups | Room temperature |
| Sea Salt 🧂 | 1 ½ tsp | Fine grain, Diamond Crystal preferred |
| Tapioca Flour 🌾 | ¼ cup | For structure and elasticity |
| Psyllium Husk Powder 🌿 | 1 tbsp | Key for gluten-free rise |
| Xanthan Gum 🧪 | ¼ tsp | Ensures proper crumb structure |
| Coconut Milk 🥛 | ¼ cup | Full-fat, for moisture |
| Baking Soda 🧪 | ½ tsp | For lift and tang |
| Coconut Sugar 🍯 | 1 tbsp | Optional, for subtle sweetness |
| Fermented Almond Starter 🌰 | ½ cup | 3-day fermented blend |
The almond flour is non-negotiable here—Bob's Red Mill blanched almond flour from trusted health food stores delivers the best texture. Psyllium husk powder, available at Whole Foods or online retailers like Thrive Market, is the secret to that signature open crumb. For the starter, ferment 1 cup almond flour + 0.5 cup coconut milk + 0.25 cup apple cider vinegar for 72 hours before using. The psyllium husk expands during proofing, creating that airy structure without gluten. If you can't find psyllium husk powder, NOW Foods sells it in bulk online.
No psyllium husk? Ground flaxseed at double the amount works in a pinch, though the texture will be denser. Substitute coconut oil with avocado oil for a neutral flavor profile. For the vinegar, raw apple cider vinegar is ideal, but white vinegar in a bind will still work. The fermented almond starter can be made with cashew flour if almonds are problematic, though almond flour provides the best protein structure. Xanthan gum is available at Amazon
Store almond flour in a cool, dark place for up to 6 months to preserve freshness. The fermented starter keeps in the fridge for 1 week or can be frozen for 3 months. For best results, prepare the dough and let it proof overnight in the fridge—this enhances flavor development. The final loaf stays fresh for 3-4 days at room temperature or 1 week in the freezer when wrapped tightly in parchment and foil. Reheat slices in a dry skillet for that freshly baked texture.

Step-by-step instructions for AIP sourdough bread
Master this gluten-free, dairy-free loaf with a perfect open crumb and crispy crust using precise technique.
Combine Wet Ingredients for Optimal Fermentation
In a medium mixing bowl, whisk together the 1.5 cups filtered water, 0.5 cup fermented almond starter, 0.25 cup apple cider vinegar, and 0.25 cup coconut milk until fully integrated. The mixture should be smooth with no visible clumps. I like to use a fork for this initial stage to avoid incorporating excess air that could affect fermentation.
Next, add the 1 tbsp psyllium husk powder and 0.25 tsp xanthan gum while whisking continuously. These binders will create the gluten-free structure, so make sure they're completely dissolved. The batter will begin to thicken noticeably within 30 seconds—this is when the psyllium starts to activate. Let this mixture sit for 5 minutes while you prepare the dry ingredients.
Incorporate Dry Ingredients for Uniform Texture
In a separate bowl, sift together the 3.5 cups almond flour, 0.25 cup tapioca flour, 1.5 tsp sea salt, 0.5 tsp baking soda, and 1 tbsp coconut sugar (if using). The sifting ensures even distribution of the baking soda and salt, which prevents uneven rise and flavor pockets. I find using a fine-mesh sieve for the almond flour helps break up any remaining lumps that can form during storage.
Gradually add the dry mixture to the wet ingredients while mixing on low speed with a hand mixer. The dough will be thick and sticky—this is normal. After 2 minutes of mixing, incorporate the 0.5 cup melted coconut oil slowly, allowing it to emulsify into the batter. The final dough should resemble a thick, slightly sticky batter with a smooth consistency. If it appears too dry, add 1 tablespoon filtered water at a time until it reaches the proper texture.
Ferment the Dough for Maximum Flavor Development
Transfer the dough to a lightly oiled 8x4-inch loaf pan and smooth the top with a wet spatula. Cover the pan tightly with plastic wrap and allow the dough to ferment at room temperature for 4-6 hours. The ideal fermentation time depends on your kitchen temperature—aim for 75-78°F. You'll know it's ready when the dough has nearly doubled in volume and shows signs of bubbling along the edges.
I recommend checking the dough after 3 hours to ensure it's rising properly. If the room is cooler, extend fermentation by 1 hour. Avoid over-fermenting, as this can lead to a dense crumb. The fermented almond starter contributes tangy depth, so this step is crucial for authentic sourdough flavor without gluten or dairy.
Preheat Oven and Prepare for Baking
Preheat your oven to 375°F with a Dutch oven placed inside for 30 minutes. This step creates steam during baking, which is essential for developing that signature crusty exterior and open crumb structure. While the oven preheats, brush the top of the dough with 1 tablespoon filtered water to create a thin moisture barrier that will help with browning.
Carefully transfer the loaf pan with the dough into the preheated Dutch oven. The dough will be sticky, so I recommend using oven mitts and working quickly. Place the Dutch oven on the middle rack and bake for 45-50 minutes, or until the internal temperature reaches 205-210°F and the top is deep golden brown with visible cracks.
Cool and Slice for Perfect Texture
Remove the bread from the oven and let it cool in the pan for 10 minutes before transferring to a wire rack. This gradual cooling prevents the loaf from collapsing. The bread will continue to firm up as it cools, and the internal structure will become more defined. I find that slicing the bread too soon results in a gummy texture, so patience is key.
Once completely cooled, slice the loaf with a sharp serrated knife. Each slice should reveal an open, airy crumb with a crispy crust. The flavor will be rich and slightly tangy from the fermented starter, with a subtle sweetness from the coconut sugar. Store any leftovers in an airtight container at room temperature for up to 3 days, or freeze for longer storage.
Pro Tips For Making Aip Sourdough Bread
- SIFT THE FLOUR: Almond flour clumps like a diva—don’t let it ruin your dough. Sift it directly into your mixing bowl before adding anything else. I used to just dump it in and wonder why my starter wouldn’t blend smoothly. Now it mixes like butter every time.
- COOL THE COCONUT OIL: Solid coconut oil? No thanks. Melt it first, then let it cool to room temperature before mixing—about 10 minutes. Cold oil makes the dough stiff and greasy; warm oil incorporates evenly. Trust me, your loaf will thank you later.
- MEASURE THE VINEGAR PRECISELY: Apple cider vinegar is acidic, and too much will kill your starter. Use a kitchen scale or a measuring spoon—no eyeballing. I once added double and got a sad, flat disc instead of a fluffy loaf. Now I weigh it: 1 tablespoon for every 2 cups flour.
- STEAM THE OVEN FIRST: Preheat your oven to 375°F (190°C), then place a metal tray on the bottom rack and pour ½ cup boiling water into it. The steam helps the crust rise without cracking—critical for almond flour’s dryness. I skipped this once and got a dense, sad loaf. Now I never forget.
Serving suggestions for leftovers
Toasted Perfection
Toast this AIP bread until golden and crispy for a satisfying crunch. Use a cast iron skillet over medium heat for 2-3 minutes per side—the thick crust handles high heat beautifully. For extra flavor, brush slices with melted coconut oil before toasting. 🔥
Soup Companion
Serve warm slices alongside hearty soups like butternut squash soup or lentil-free minestrone. The open crumb soaks up broth beautifully while maintaining structure. I like to tear the bread into irregular chunks for easy dipping. For a rustic touch, sprinkle with flaky sea salt before serving.
Protein Pairings
Create AIP-friendly sandwiches with this bread as the base. Try grilled chicken thighs with avocado mash and sprouted greens, or seared salmon with mashed cauliflower and caramelized onions.
The neutral flavor lets the protein shine while providing structure. For a sweet option, spread with almond butter and sliced banana.
Dinner Rolls
Cut the loaf into 1-inch thick slices and serve as dinner rolls. Warm them in a 350°F oven for 5-7 minutes until fragrant. Pair with herb-roasted meats or vegetable stews.
The dense yet airy crumb holds up perfectly to juicy proteins. For a gourmet touch, drizzle with olive oil and finely chopped rosemary before serving.
Breakfast Option
Toast thick slices and top with almond butter, sliced strawberries, and a sprinkle of coconut sugar for a satisfying morning meal. The bread's subtle tang balances sweet toppings beautifully. For extra protein, add collagen peptides mixed into the almond butter. 🍓
Garnishing Ideas
Elevate your serving with simple garnishes. A drizzle of extra virgin olive oil and crushed garlic adds Mediterranean flair, while fresh thyme leaves bring herbal brightness.
For a savory touch, sprinkle with toasted sesame seeds (if tolerated on AIP). Always serve with a sharp serrated knife to showcase the open crumb structure.

Frequently asked questions
Can I substitute almond flour with another nut or seed flour?
Yes, but results may vary. Cashew flour works best for texture, though the crumb will be slightly denser. Sunflower seed flour is another option, but it lacks the protein structure of almond flour. For a lighter loaf, blend 50% almond flour with 50% coconut flour, but expect a drier result. Always adjust liquid ratios—nut flours absorb moisture differently than almond flour.
Why does my AIP sourdough turn out dense instead of open-crumb?
Dense bread usually means underproofing or insufficient psyllium husk. First, verify your fermented almond starter is active (it should bubble). Second, ensure you used 1 tbsp psyllium husk powder—this is critical for gluten-free rise. If the dough didn't double in volume during fermentation, extend the time by 1-2 hours at room temperature. For extra lift, try adding 0.25 tsp baking soda to the dry mix.
How do I know when the fermented almond starter is ready?
The starter is ready when it shows visible bubbles and has a tangy, slightly sour aroma (similar to traditional sourdough). For best results, ferment for 72 hours at room temperature, stirring daily. If stored in the fridge, remove it 24 hours before use to reactivate. The starter should float in water—this confirms proper fermentation. If it sinks, extend fermentation by 12-24 hours.
Can I bake this bread without a Dutch oven?
Yes, but you'll need to create steam manually. Place the loaf pan in a cold oven, then immediately pour 1 cup boiling water into a baking dish on the lower rack. Bake at 375°F for 50-55 minutes, adding more water if needed to maintain moisture. Without the Dutch oven, the crust may be less crispy, but the crumb will still be open. For extra browning, brush the top with filtered water after 20 minutes.
What's the best way to store leftovers to keep them fresh?
Wrap cooled slices tightly in parchment paper, then place in an airtight container with a silica gel packet to absorb moisture. Store at room temperature for 3 days or freeze for 3 months. To reheat, warm slices in a 350°F oven for 5 minutes or toast in a dry skillet until crispy. Avoid refrigerating—it dries out the crumb faster than room storage.
