Side Dishes
This AIP sourdough bread recipe delivers the tangy, airy texture of traditional sourdough without gluten, yeast, or grains—perfect for the Autoimmune Protocol. The secret lies in fermenting a blend of compliant flours (almond, cassava, and coconut) with apple cider vinegar to mimic sourdough's signature tang.
I developed this after struggling to find a bread that met AIP standards while still satisfying that craving for fresh, crusty loaves.
The process begins with a 24-hour fermentation at room temperature, allowing flavors to develop naturally without yeast. Unlike traditional sourdough, this version uses a simple starter made from flour and vinegar, creating that familiar tang through acidity rather than microbial activity.
The result is a bread with a crisp crust and tender crumb that holds up beautifully for toast or sandwiches.
What sets this recipe apart is its versatility—it works as a side, base for soups, or even as a vehicle for AIP-friendly toppings. The fermentation process enhances digestibility, making it gentler on sensitive systems while still delivering satisfying texture.
With just 8 ingredients and 30 minutes of active prep time, this bread proves AIP dining doesn't mean sacrificing comfort food.
Baked in a Dutch oven for even heat distribution, this loaf emerges with a golden crust and an open crumb structure. Store at room temperature for up to 3 days or freeze for longer shelf life.
The recipe scales easily, so you can bake one loaf for daily meals or make two for sharing. Let's get started on your first AIP-compliant sourdough.
Ingredients for aip sourdough bread
Eight compliant ingredients transform into a tangy, gluten-free loaf with restaurant-quality texture.
| Ingredient | Amount | Notes |
|---|---|---|
| Almond Flour 🌰 | 2 cups | Finely ground, unsweetened |
| Cassava Flour 🥔 | 1 cup | Starch-rich, fine texture |
| Coconut Flour 🥥 | ½ cup | Absorbs moisture well |
| Apple Cider Vinegar 🍏 | ½ cup | Raw, unfiltered preferred |
| Filtered Water 💧 | 1 ¼ cups | Room temperature |
| Psyllium Husk Powder 🌿 | 2 tbsp | Critical for structure |
| Sea Salt 🧂 | 1 ½ tsp | Fine grain preferred |
| Tapioca Starch 🍚 | ½ cup | For crisp crust |
The almond flour provides structure and richness, but Bob's Red Mill or Anthony's Goods brands are essential—pre-ground flours work best. Cassava flour from Bob's Red Mill or Arrowhead Mills ensures proper fermentation without grittiness. Coconut flour must be high-quality, unsweetened—Bob's Red Mill again is reliable. Apple cider vinegar should be raw and unfiltered for maximum tang; Bragg or White House Foods are excellent choices. Psyllium husk powder from Nature's Way or Now Foods creates the elastic quality traditional sourdough lacks.
No almond flour? Sunflower seed flour works at a 1:1 ratio, though texture will differ slightly. Cassava flour unavailable? Tapioca starch can replace up to half, but expect denser crumb. For coconut flour, arrowroot powder substitutes at the same weight, though binding properties vary. Vinegar substitutes? Lemon juice works in a pinch, but flavor will be milder. Psyllium husk can be omitted entirely, but the bread may lack structure—chia seeds soaked in water provide a partial alternative. Always measure flours by weight for consistency, as scooping leads to packing variations.
Mix the starter 24 hours ahead and store at room temperature. Flours should be refrigerated in airtight containers to prevent moisture absorption. The psyllium husk powder keeps indefinitely but loses potency after 6 months. For longer storage, freeze dough portions wrapped in parchment paper for up to 3 months. Reheat slices in a toaster or oven to restore crispness. This bread benefits from being baked the day it's needed—fermentation continues even when refrigerated, affecting texture.
Why You'll Love This Recipe
- No-Fuss Fermentation: Honestly, the starter is just apple cider vinegar and water—no waiting weeks for a wild yeast party. Mix, let sit overnight, and you’re done. That’s it. No stress, no guesswork.
- Nutty-Creamy Crunch: The almond flour gives it this rich, almost buttery depth, while the cassava flour keeps it light. Toast a slice, and that crispy crust? It’s the kind of thing that makes you pause mid-morning coffee.
- Weeknight Wonder: Between us, this is my go-to for sandwiches, toast, or even croutons—no fancy prep. The coconut flour adds a subtle sweetness that pairs with everything, from avocado to soup. (Yes, even on a Tuesday night.)
- Budget-Friendly Staple: A single batch stretches for days—freeze half, and you’ve got fresh bread anytime. Plus, almond and cassava flour are cheaper than you’d think, especially if you buy in bulk. My wallet and my gut thank me.
Step-by-step instructions for AIP sourdough bread
This gluten-free method delivers authentic sourdough flavor using natural fermentation and precise hydration.
Combine Dry Ingredients for Optimal Structure
In a large mixing bowl, whisk together the 2 cups almond flour, 1 cup cassava flour, 0.5 cup coconut flour, 2 tbsp psyllium husk powder, and 1.5 tsp sea salt. The psyllium husk is critical here—it creates the gluten-like structure that gives this bread its rise and chewiness. I like to use a whisk for this step to ensure all ingredients are thoroughly blended and there are no flour pockets remaining.
Coconut flour absorbs moisture aggressively, so don't skip this blending step. The mixture will appear dry but will transform dramatically once we add the wet ingredients. Set this bowl aside while you prepare the liquid components.
Create the Acidic Hydration Base
In a separate bowl, combine the 1.25 cups filtered water at room temperature with the 0.5 cup apple cider vinegar and 0.5 cup tapioca starch. The vinegar serves as our acidifier, replacing yeast while providing that characteristic tang. Stir until the tapioca starch dissolves completely—you should have a smooth, slightly thick liquid without any graininess.
This acidic hydration is what will activate the psyllium husk later. If you notice any lumps, strain the mixture through a fine-mesh sieve to ensure a perfectly smooth batter. The texture should be similar to heavy cream but slightly thicker due to the starch content.
Hydrate the Dough and Develop Structure
Pour the wet mixture into the dry ingredients and stir vigorously for 3-4 minutes using a sturdy silicone spatula. The psyllium husk will begin to activate, creating long strands that give the bread its structure. You'll notice the dough transform from a dry powder to a thick, shaggy mass that clings to the spatula.
At this point, the dough should be cohesive but still quite sticky. This is normal—our gluten-free substitute needs more time to develop its structure. Let the dough rest for 10 minutes while you prepare your baking vessel. This short rest allows the psyllium to fully hydrate and begin forming its elastic network.
Shape and Proof for Optimal Rise
After the rest, wet your hands with water and gently shape the dough into a round loaf. The dough will be quite sticky, so work quickly but carefully to avoid tearing. Place it in a greased 8-inch round baking pan or a well-oiled Dutch oven. The shape should be smooth on top with slightly rough edges—this indicates proper handling.
Cover the pan with a clean kitchen towel and let the dough proof at room temperature for 1-2 hours. You're looking for about a 30-50% rise—the dough should puff noticeably but not double in size like traditional yeast bread. The psyllium creates a different type of rise, so don't expect dramatic volume changes. When it's ready, the dough will feel slightly springy when pressed gently with your finger.
Bake for Crisp Exterior and Moist Crumb
Preheat your oven to 375°F with a baking stone or inverted baking sheet on the middle rack. This creates steam that's essential for our gluten-free bread. Once preheated, carefully transfer the proofed dough (still in its pan) to the oven. Bake for 40-45 minutes until the top is deep golden brown and the internal temperature reaches 205°F when measured with an instant-read thermometer.
The bread is done when it sounds hollow when tapped on the bottom and pulls away cleanly from the sides of the pan. Let it cool in the pan for 10 minutes before transferring to a wire rack to cool completely. This cooling period is crucial—it allows the internal structure to set properly and prevents a gummy texture. The crust should be crisp while the interior remains moist and tender, with that authentic sourdough tang from the apple cider vinegar.
Pro Tips For Making Aip Sourdough Bread
- Mix Flours First: Combine almond and cassava flours in a fine-mesh sieve before adding coconut flour—this prevents clumping and ensures even hydration. I learned this the hard way when my first batch turned out dense because the coconut flour absorbed water unevenly.
- Acidify Gradually: Add apple cider vinegar to water after mixing dry ingredients—this keeps the batter from curdling prematurely. Pour it in slowly while stirring, and let the batter rest for 5 minutes before folding in the wet starter.
- Skip Overmixing: Fold the batter just until combined—overworking it activates too much gluten from the almond flour, making the bread tough. Use a spatula to gently lift and fold, stopping when no dry spots remain.
- Bake Low and Slow: Preheat the oven to 325°F (not higher) and bake for 50–60 minutes—this prevents a dense center while letting the crust crisp properly. I used to rush it at 350°F, and the bread always came out gummy inside.
Essential equipment for this recipe
Dutch Oven Essentials
A 5-quart Dutch oven from Le Creuset or Lodge is my top recommendation for this recipe. The heavy cast iron retains heat evenly, creating that perfect crisp crust while keeping the interior moist.
I prefer the Lodge Pre-Seasoned Dutch Oven for its affordability and excellent heat distribution—it's my go-to for all gluten-free baking. 🔥
Mixing Tools
Use a sturdy silicone spatula (like OXO Good Grips) for mixing the dough—it handles the sticky texture beautifully without tearing. A whisk (I love Mercer Culinary Genesis) is essential for blending dry ingredients thoroughly. Avoid metal whisks that can scratch your Dutch oven's seasoning over time.
Measuring Precision
Invest in a digital kitchen scale (like OXO Good Grips) for accurate measurements—especially for flours like almond and coconut which vary in density. A fine-mesh sieve (I use Norpro) ensures smooth batter when straining the tapioca starch mixture. Precise measurements are critical for this recipe's structure.
Proofing Setup
For proofing, I recommend a proofing basket (like West Bend) or simply a clean kitchen towel. The towel method works perfectly with this sticky dough.
Place your proofing vessel on a wire rack (not directly on the counter) to allow airflow underneath—this helps prevent condensation buildup that can make the dough soggy.
Baking Accessories
A baking stone (like Lodge) on the middle oven rack creates steam for that perfect crust. For temperature monitoring, use an instant-read thermometer (I recommend Thermoworks) to check the internal temperature. A parchment-lined baking sheet makes transfers easier when cooling the bread.
Storage Solutions
Store cooled bread in an airtight container (like Rubbermaid) at room temperature for up to 3 days. For longer storage, freeze portions wrapped in parchment paper for up to 3 months.
A wire cooling rack (like OXO Good Grips) is essential for proper cooling after baking—it prevents moisture buildup that can make the bread gummy.

Frequently asked questions
Can I make this AIP bread without psyllium husk?
The psyllium husk is essential for structure, but you can substitute 2 tablespoons of ground chia seeds mixed with 2 tablespoons of water (let it gel for 5 minutes first). The texture will be slightly denser, though. Without either, your bread may crumble or lack chewiness. For best results, stick with psyllium if possible.
How do I know when the dough is properly proofed?
Look for a 30-50% rise—the dough should puff noticeably but not double like yeast bread. Gently press your finger: if it springs back slowly (not quickly), it's ready. The surface may develop small cracks. Overproofing is less risky here since psyllium doesn't activate like yeast. Proofing time varies by humidity—warmer kitchens may need 1 hour, cooler ones up to 2 hours.
Why does my AIP sourdough taste bland?
The tang comes from the apple cider vinegar—use raw, unfiltered vinegar for maximum flavor. For extra depth, add 1 teaspoon of garlic powder or 1/2 teaspoon of onion powder to the dry ingredients. Let the dough proof longer (2-3 hours) to develop more complex flavors through fermentation. The vinegar should smell sharp before baking.
Can I make this bread in a regular loaf pan instead of round?
Yes! Use a 9x5-inch loaf pan greased with coconut oil. The baking time remains 40-45 minutes, but check for doneness at 35 minutes—it may bake faster in a rectangular shape. For a more open crumb, slash the top with a sharp knife before baking. The texture will be slightly denser than round, but still delicious.
How do I revive stale AIP sourdough?
Slice and toast in a 375°F oven for 5-7 minutes or wrap in a damp towel and microwave for 20-30 seconds. For longer-term storage, freeze slices wrapped in parchment paper—thaw at room temperature before reheating. The psyllium-based structure holds moisture better than traditional bread, but it still benefits from quick reheating.
