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

This AIP sourdough bread delivers the tangy depth and satisfying texture of traditional sourdough—without gluten, dairy, or eggs. The secret lies in a long fermentation with psyllium husk and apple cider vinegar, creating a light, airy crumb that rivals artisanal loaves.

I developed this recipe after years of experimenting with grain-free baking, and the results are nothing short of impressive for an AIP-friendly version.

The process begins with a 24-hour starter made from psyllium husk and filtered water, which mimics the natural leavening of traditional sourdough. Unlike quick breads, this method allows flavors to develop fully, resulting in a bread with a crisp crust and a tender, slightly chewy interior.

The tang comes from apple cider vinegar, which also helps tenderize the crumb without relying on dairy or eggs.

By the time you pull it from the oven, you’ll have a loaf with that classic sourdough aroma—warm, slightly sweet, with a hint of vinegary sharpness. The texture is surprisingly light for a grain-free bread, thanks to the psyllium’s ability to bind moisture while creating structure.

It’s perfect for toast, sandwiches, or simply enjoying fresh with olive oil and sea salt.

This recipe is designed to be foolproof for beginners, with clear steps for fermenting, shaping, and baking. The key to success? Patience—letting the dough rest and ferment properly ensures the best rise and flavor. Once you master it, you’ll never miss traditional sourdough again.

Ingredients for aip sourdough bread

Nine simple ingredients transform into a loaf with artisanal sourdough flavor—no gluten, dairy, or eggs needed.

Psyllium husk is the backbone of this recipe—look for brands like Now Foods or Nutrabio at health food stores or online. The raw, unfiltered apple cider vinegar adds that signature tang (I grab mine from Trader Joe's or Whole Foods bulk section). For the flours, Bob's Red Mill tapioca and arrowroot are my go-tos—they're finely milled and consistent. The sunflower lecithin might be new to your pantry, but it's a game-changer for binding without eggs. If you can't find it, skip it—the bread will still rise, just slightly less cohesive.

No psyllium husk powder? Ground flaxseed at double the amount works in a pinch, though texture will differ. Substitute arrowroot with more tapioca flour if needed. For the vinegar, white vinegar at half the amount gives similar acidity but less complexity. The olive oil should be fruity and peppery—California Extra Virgin brands like Corto or Gaia are perfect. If you're short on time, pre-ferment the psyllium starter overnight—it's the secret to that authentic sourdough flavor without the wait.

Store the psyllium husk in an airtight container away from light—it stays potent for 6-12 months. Once baked, the bread keeps well wrapped at room temperature for 2-3 days or frozen for 3 months. For best results, reheat slices in a toaster or warm oven. I always make a double batch—one for toasting, one for freezing. The crust gets crunchier as it sits, so save slices for later if you can't eat the whole loaf at once.

Step-by-step instructions for AIP sourdough bread

Here's how to create a light, airy gluten-free loaf with that perfect tangy sourdough flavor.

In a medium bowl, whisk together the 0.5 cup psyllium husk powder and 1.5 cups filtered water until completely dissolved. You should see a thick, gel-like consistency form—this is what gives our gluten-free bread its structure. Let it sit for 5 minutes while you prepare the other ingredients. The mixture will thicken further as it hydrates, so don't be surprised if it becomes almost paste-like.

I like to use a silicone spatula for this step—it's easier to scrape up every last bit of that thick mixture. This hydration step is absolutely critical; when we mix it into the dry ingredients later, it will create the gluten-free equivalent of gluten's elastic properties. If you notice any lumps, simply whisk them out—they'll disappear as the mixture sits.

In a large mixing bowl, combine the 2 cups tapioca flour, 0.25 cup arrowroot powder, 1.5 tsp sea salt, and 0.5 tsp baking soda. Whisk these dry ingredients together until evenly distributed—this ensures consistent flavor and texture throughout the bread. In a separate small bowl, mix the 0.5 cup extra-virgin olive oil and 1 tsp sunflower lecithin until fully combined.

Create a well in the center of your dry ingredients and pour in the psyllium mixture you prepared earlier. Then, add the olive oil-lecithin mixture. Using a sturdy whisk or rubber spatula, gently fold everything together until just combined. You're looking for a thick, sticky dough that comes together when pressed—don't overmix or you'll develop a tough texture. The dough should be cohesive but still slightly sticky to the touch, which is perfect for our gluten-free structure.

Preheat your oven to 350°F and line a 9x5-inch loaf pan with parchment paper, allowing it to extend slightly over the edges for easy removal later. Melt the 2 tbsp coconut oil and brush it generously over the bottom and sides of the prepared pan. This creates a non-stick barrier and adds subtle flavor to the crust. I like to use a pastry brush for this—it helps distribute the oil evenly without creating a greasy mess.

Here's a pro tip: Sprinkle a thin layer of the 1 tbsp psyllium husk seeds along the bottom of the pan before adding the dough. This will create a beautiful textured crust on the bottom of your loaf. The seeds add a subtle crunch and visual appeal that makes this bread look even more impressive when sliced.

Transfer the dough to your prepared loaf pan and spread it evenly, pressing down gently to remove any air bubbles. The dough will be quite sticky, so I recommend using wet hands or a damp spatula to help shape it. Tap the pan gently on the counter a few times to help the dough settle into the corners. Sprinkle the remaining psyllium husk seeds evenly over the top of the dough, pressing them in lightly so they adhere.

Bake in the preheated oven for 50-60 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. The bread is done when it springs back slightly when pressed in the center—this indicates proper doneness. If the top browns too quickly, tent the pan with aluminum foil after 30 minutes to prevent over-browning while the center continues to cook.

Allow the bread to cool in the pan for 10 minutes before carefully removing it from the pan using the parchment paper handles. Transfer to a wire rack and let it cool completely for at least 1 hour before slicing. This cooling period is crucial—it allows the internal structure to set properly, preventing a gummy texture when you slice into it.

Once fully cooled, slice the bread with a sharp serrated knife. You'll be rewarded with a beautifully textured loaf that slices cleanly and has that perfect tangy depth from the apple cider vinegar. Store any leftovers in an airtight container at room temperature for up to 3 days, or freeze slices for up to 3 months—this bread actually tastes better the next day as the flavors develop further.

Make-ahead tips for leftovers

Psyllium Starter Prep

Make your psyllium starter the night before to save time—this is the secret to that authentic sourdough tang. Mix 0.5 cup psyllium husk powder with 1.5 cups filtered water and 0.5 cup apple cider vinegar in a jar. Cover loosely and let sit at room temperature for 12-24 hours.

The mixture should thicken like yogurt and develop a pleasant tang. I keep mine on the counter overnight—it's ready when it's thick and gel-like, not runny. 💫

Dough Prep Ahead

After mixing your dough, cover it tightly with plastic wrap and refrigerate for up to 24 hours before baking. This cold fermentation enhances flavor and improves texture. When you're ready to bake, let the dough sit at room temperature for 30-60 minutes first—this helps it rise properly in the oven.

I always do this the morning of baking so I can enjoy fresh bread at lunchtime. The dough will be more manageable after chilling, too.

Freezing Tips

Slice your cooled bread and freeze individual pieces between parchment paper in a single layer. Once frozen, transfer to a freezer bag with all air removed. Toast directly from frozen—no thawing needed! I find this method preserves the crust's crunch perfectly.

For extra flavor, brush thawed slices with melted coconut oil before toasting. This bread actually reheats beautifully, making it perfect for meal prep. ❄️

Storage Containers

Use an airtight container with a silicone lid to keep your bread fresh longer. I recommend Glasslock containers—they maintain moisture while preventing staling. For short-term storage (up to 3 days), keep at room temperature. If storing longer than 2 days, slice and freeze immediately.

The bread's texture stays best when stored this way, with minimal drying out. Always let slices cool completely before storing to prevent condensation from making the crust soggy.

Batch Prep Strategy

Double the recipe and bake two loaves at once—this is my favorite time-saver. Use two loaf pans or divide the dough between them. The second loaf makes great sandwich bread for the week, while the first can be enjoyed fresh.

I like to freeze one loaf completely before slicing, then store the slices in bags. This way, I always have perfectly fresh-tasting bread whenever I need it. The extra work upfront pays off with minimal daily effort. 💪

Reheating Secrets

For maximum crispiness, reheat slices in a toaster or toaster oven for 2-3 minutes until golden brown. If using an oven, bake at 350°F for 5-8 minutes on a wire rack. Avoid microwaving—it makes the crust rubbery.

I also love brushing slices with olive oil before toasting for that artisanal bakery feel. The reheating process revives the crust while keeping the interior moist and flavorful. This is especially important for AIP bread that doesn't contain dairy or eggs to help retain moisture.
