Ingredients for aip sourdough bread
Three flours, one fermented magic trick—this AIP sourdough rises like traditional bread without gluten, eggs, or dairy.
| Ingredient | Amount | Notes |
|---|---|---|
| Coconut Milk (full-fat, canned) 🥥 | 1 can | For starter and dough hydration |
| Cassava Flour 🌾 | 2 cups | AIP-compliant, fine texture preferred |
| Tapioca Flour 🍠 | 1 cup | For elasticity and structure |
| Arrowroot Powder 🌿 | ½ cup | Lightens crumb and improves rise |
| Psyllium Husk Powder 🌱 | 2 tbsp | Essential for gluten-free structure |
| Sea Salt 🧂 | 2 tsp | Fine grain for even distribution |
| Raw Apple Cider Vinegar 🍎 | 1 tbsp | For starter acidity |
| Filtered Water 💧 | 1 ½ cups | Room temperature preferred |
| Coconut Oil (refined) 🥥 | 2 tbsp | For dough and pan coating |
| Maple Syrup 🍁 | 1 tbsp | Sweetener for fermentation |
| Chia Seeds (optional) 🌱 | 1 tbsp | For extra structure if needed |
The cassava flour is your workhorse here—Bob's Red Mill or Anthony's Goods are my go-tos for consistent texture. Tapioca flour? Bob's Red Mill again, but check the expiration date—older flour loses its elasticity. Psyllium husk powder is non-negotiable; Now Foods sells it in bulk, and it’s worth the small price for that perfect crumb. For the coconut milk, full-fat canned is a must—the creaminess feeds your starter better than cartons. If you're near a Latin market, they often sell it cheaper than the grocery store. The psyllium husk? Measure it carefully—too much and your dough gets gummy, too little and it collapses. I always weigh mine out on a digital scale for precision.
No psyllium husk? Extra tapioca flour plus 1 tbsp chia seeds can help, but it won’t be identical. Running low on cassava flour? Sweet potato starch works in a pinch, though the flavor’s slightly different. The apple cider vinegar can be swapped for lemon juice at half the amount—just adjust the salt to balance. For the coconut milk, coconut cream from the can works too, but save the water for later. The maple syrup is optional but recommended; if you skip it, date syrup or coconut sugar are AIP-friendly swaps. Pro tip: If your starter smells funky after 24 hours, it’s still fine—just give it an extra hour or two. Patience is key with sourdough.
This bread keeps 3-4 days at room temp if wrapped tightly in a cotton towel (no plastic—it traps moisture). For longer storage, freeze fully cooled loaves wrapped in parchment and foil; they’ll last 3 months. To reheat, wrap in a damp towel and warm in a 200°F oven for 10 minutes. The crust gets crispier the second day, so plan ahead. Slice with a serrated knife—it’s denser than regular bread. Leftovers? Toast them—coconut oil brushed on before toasting makes them irresistible. And if you bake two batches, freeze one immediately; you’ll thank me later.

Step-by-step instructions for AIP sourdough bread
This gluten-free, egg-free sourdough delivers authentic rise and texture without compromising flavor.
Prepare the Sourdough Starter
Open the 1 can full-fat coconut milk and whisk vigorously until smooth. In a clean bowl, combine the coconut milk with 1.5 cups filtered water, 1 tbsp raw apple cider vinegar, and 1 tbsp maple syrup. This creates your starter base—think of it as the yeast substitute that will kick off fermentation.
Next, add 2 tbsp psyllium husk powder and mix thoroughly until fully dissolved. The psyllium acts as a binder, mimicking gluten's structure in traditional bread. Let this mixture sit at room temperature for 1 hour, stirring every 15 minutes to ensure even hydration. You'll notice it thicken slightly as the psyllium absorbs liquid—this is normal and crucial for the dough's structure later.
Mix the Dough Components
In a large mixing bowl, combine 2 cups cassava flour, 1 cup tapioca flour, and 0.5 cup arrowroot powder. Whisk these dry ingredients together to eliminate any lumps—this ensures an even crumb texture. Create a well in the center and pour in the starter mixture you prepared earlier.
Gradually incorporate the dry ingredients into the wet, mixing with a wooden spoon or silicone spatula until you achieve a shaggy dough consistency. The mixture should be thick but still pourable. Here's where the magic happens: add 2 tbsp refined coconut oil and 2 tsp sea salt, mixing until fully combined. If using, sprinkle in 1 tbsp chia seeds now—they'll add extra structure to the final loaf.
Hydrate and Knead the Dough
Slowly pour in the remaining 1.5 cups filtered water while mixing continuously. The dough will transform from shaggy to cohesive as the liquid hydrates all the dry ingredients. Use your hands to work the dough for 5-7 minutes, pressing and folding until it becomes smooth and elastic. You're not developing gluten like in traditional bread, but you're creating the right balance of moisture and structure.
Here's the thing—this dough should be slightly sticky but manageable. If it feels too wet, add 1-2 tablespoons of cassava flour at a time until it comes together. The ideal consistency is similar to thick pancake batter that holds its shape when pressed. Cover the bowl with a damp towel and let it rest at room temperature for 30 minutes—this allows the psyllium to fully activate and the dough to relax.
Shape and Proof the Loaf
Lightly grease a 9x5-inch loaf pan with coconut oil to prevent sticking. Transfer the rested dough to the prepared pan and smooth the top with a wet spatula, pressing gently to eliminate air bubbles. The dough should reach the top of the pan—don't be afraid to pack it in firmly. This step ensures maximum rise and a proper crumb structure.
Cover the pan with a damp towel and let the dough proof at room temperature for 2-3 hours, or until it has risen about 50% above the pan's rim. You'll know it's ready when the top springs back slowly when pressed with a finger—this indicates proper fermentation. Preheat your oven to 350°F while the dough proofs. The residual heat from the oven will help create that perfect oven-spring when baking begins.
Bake to Golden Perfection
Carefully transfer the proofed loaf to the preheated oven and bake for 45-50 minutes, until the top is deep golden brown and the internal temperature reaches 205°F when measured with an instant-read thermometer. The bread should sound hollow when tapped on the bottom—this confirms it's fully baked through.
Remove from the oven and let the bread cool in the pan for 10 minutes before transferring to a wire rack. This resting period prevents the loaf from collapsing as it cools completely. Once cooled, slice with a serrated knife for clean cuts that reveal the open crumb structure. The interior should be tender with a slight chew, and the crust should have that satisfying crack you'd expect from traditional sourdough.
Pro Tips For Making Aip Sourdough Bread
- Whisk the Coconut Milk: Heat the full-fat canned coconut milk to 180°F (82°C) first—this melts the fats evenly and prevents clumpy dough later. I learned this the hard way after fighting lumps in my first batch; now I just pop the can in a saucepan for 5 minutes.
- Sift the Psyllium Last: Mix cassava and tapioca flours first, then whisk in psyllium and arrowroot after adding the coconut milk. This keeps the psyllium from clumping—it’s dry and stubborn, and you’ll regret stirring it in too early.
- Don’t Over-Knead the Dough: This isn’t gluten-based, so handle it like a delicate batter—just fold the psyllium in until no dry spots remain. Overworking it turns the bread dense; treat it like a pancake batter, not sourdough.
- Steam the Loaf: Place a metal bowl of boiling water on the oven rack before baking—this creates steam for the first 10 minutes. The crust stays crisp without burning, and the crumb stays light. (Yes, even if you’re impatient like me.)
Storing and reheating your leftovers
Room Temperature Storage
Wrap your cooled AIP sourdough loaf tightly in a cotton towel (never plastic—it traps moisture) and store it in a cool, dark pantry for up to 3-4 days. The crust develops even more flavor and crispness over time, making day-old slices perfect for toast.
I always keep a loaf on hand for quick meals—it’s the ultimate AIP pantry staple. 🥖
Freezer Prep Tips
For longer storage, freeze your bread fully cooled by wrapping it in parchment paper followed by aluminum foil. This double-layer method prevents freezer burn and maintains freshness for up to 3 months.
Label with the date—trust me, you’ll forget which loaf is oldest! Thaw overnight at room temperature or reheat straight from frozen. ✨
Reheating Methods
For that fresh-baked feel, wrap a slice in a damp paper towel and reheat in a 200°F oven for 5-7 minutes. The steam softens the crumb while crisping the crust.
Or, for quick toast, brush slices with melted coconut oil and toast in a dry skillet over medium heat for 2-3 minutes per side. The oil adds richness without dairy. 🔥
Reviving Stale Bread
If your loaf loses its freshness, don’t toss it! Pop slices in a 350°F oven for 5-10 minutes with a splash of water in the pan. The steam revives the texture—perfect for croutons or breadcrumbs.
I’ve rescued many a "stale" loaf this way. Pro tip: Store breadcrumbs in an airtight container in the freezer for up to 6 months. 💡
Portioning for Meal Prep
Slice your loaf before freezing for grab-and-go portions. Wrap individual slices in parchment paper and store in a ziplock bag—they’ll stay fresh for 2 weeks.
Toast straight from frozen for a warm breakfast. This is my go-to strategy for busy mornings when I need AIP-friendly bread in seconds. 📅
Crust Refresh Tricks
If the crust softens after storage, broil the loaf for 1-2 minutes to restore crispness. For extra crunch, brush with melted coconut oil before reheating. A quick broil also works wonders for reviving the texture of day-old bread—just watch closely to avoid burning. 🌟

Frequently asked questions
Can I substitute any of the flours in this AIP sourdough recipe?
You can make small swaps, but keep the ratios balanced. Replace 1:1 cassava flour with sweet potato starch for a slightly sweeter flavor, or use arrowroot powder instead of tapioca flour (though it lacks elasticity). Never exceed 1 cup total tapioca flour—it's what gives the bread its structure. The psyllium husk is non-negotiable for gluten-free rise, but you can add 1 extra tbsp chia seeds if needed for extra binding.
Why does my AIP sourdough starter smell funky after 24 hours?
That's completely normal! A healthy starter will develop a tangy, slightly sour aroma from fermentation—think yogurt or vinegar. If it smells like rotten eggs or ammonia, it's over-fermented (just toss it and start fresh). The coconut milk starter should thicken noticeably by 12-24 hours—this means it's ready for baking. Pro tip: Keep your workspace clean to avoid contamination smells.
How do I know when my AIP sourdough is fully baked?
Look for three signs: deep golden brown crust, internal temp of 205°F (use a thermometer), and a hollow sound when tapped on the bottom. The edges should pull away from the pan slightly. If unsure, bake 5 more minutes—underbaking makes the bread gummy. Let it cool 10 minutes in the pan before slicing, or it'll fall apart.
Can I make this AIP sourdough without psyllium husk?
It's possible but challenging. Replace the 2 tbsp psyllium with 2 tbsp extra tapioca flour + 1 tbsp chia seeds, but expect a denser crumb. The psyllium mimics gluten's elasticity—without it, your bread may crumble or lack rise. If you must skip it, increase the proofing time to 4 hours and bake at 325°F for longer to compensate.
Why does my AIP sourdough taste bland compared to regular sourdough?
Two likely reasons: under-fermented starter (try proofing 12 hours instead of 24) or missing acidity. Add ½ tsp extra apple cider vinegar to the starter or use 1 tbsp coconut aminos in the dough for umami depth. The coconut milk also adds richness—don't skimp! For extra flavor, brush the baked loaf with melted coconut oil before serving.
