How to make gluten-free sourdough bread
The night before you mix the dough, feed your gluten-free sourdough starter to be active in the morning.
Line a 9" x 5" baking pan with parchment paper. If your oven has a bread-proofing setting, turn it on. If it does not, turn your oven to the lowest temperature it will register.

Step 1
Mix the wet ingredients in a small bowl.

Step 2
Measure out the dry ingredients in a stand mixer bowl. Use the paddle attachment to mix the dry ingredients thoroughly.

Step 3
Add the wet ingredients to the stand mixer bowl.

Step 4
Mix the dough at the lowest speed for 5 minutes. Don't skip this step. It's very important to mix the dough well, and this step also helps incorporate some air into the dough.
Use a hand-held electric mixer if you do not have a stand mixer.
The batter will be thick.

Step 5
Pour the dough into the pan and use a spatula to smooth the top.

Step 6
Cover with plastic and let rise in the oven with the breadproofing setting ON. If you don't have that setting, at this point, turn the oven OFF.
Allow the dough to rise for 3 ½ to 4 hours or until it reaches the top of the pan.

Step 7
Remove the dough from the oven and turn the oven on to 375°F(190°C).
When the oven has come to temperature, score the top of the loaf with a razor or sharp knife to help improve the oven spring and give the loaf a decorative touch.

Step 8
Bake the loaf for 60 minutes.
Remove the baked loaf from the pan and parchment paper immediately.
If you do not remove the parchment paper, the bottom of the bread will become soggy.
Allow the bread to cool completely on a cooling rack before cutting.

How to Store
You can store the bread at room temperature in a closed container for up to 3 days or freeze it for up to 3 months.

Gluten Free Sourdough Bread
INGREDIENTS
Ingredients needed to make 1 cup (250 g) active starter
- ½ cup (125 g) unfed gluten free sourdough starter
- ½ cup (70 g) brown rice flour
- ¼ cup (60 g) water
Wet Ingredients
- 1 ½ cups + 2 tablespoons (390 g) water
- 2 tablespoons (10 g) ground flax seed
- 1 cup (250 g) gluten free sourdough starter
- 1 tablespoon (20 g) honey (or agave)
- ¼ cup (60 g) olive oil
- 1 teaspoon (5 g) apple cider vinegar
Dry Ingredients
- 1 ½ cups (210 g) brown rice flour
- 1 cup (120 g) tapioca flour
- ½ cup (60 g) corn starch
- 2 tablespoons (16 g) psyllium husks
- 2 ½ teaspoons (8 g) xanthan gum
- 2 teaspoons (10 g) salt
- 1 tablespoon baking powder
INSTRUCTIONS
Feed Your Starter
- 12 hours before you plan to mix the dough, add the ingredients to make 1 cup (250 g) of active sourdough starter to a clean jar. Stir until combined, loosely cover the jar and let the starter rise at room temperature. The sourdough starter is ready to use when there are plenty of bubbles on the sides of the jar and the starter has risen by 25-30%.
Make the Dough
- Combine the water with the ground flax seeds, active gluten free sourdough starter, honey, olive oil, apple cider vinegar in a mixing bowl and set aside.
- Combine the dry ingredients in the bowl of a stand mixer. Use the paddle attachment to mix them for 1 to 2 minutes making sure they are well incorporated. This step is very important.
- Pour the wet ingredients into the bowl of the stand mixture with the dry ingredients.
- Beat the dough on the lowest speed for 5 minutes, scrapping down the sides of the bowl as necessary. When you lift the paddle attachment, the dough should slowly fall off of the paddle. If it stays on the paddle, add 30 g of water at a time until you achieve the right consistency. The dough should be thick but not stiff.
Rise
- Line a 9" x 5" baking tin with parchment paper. Pour the dough into the tin and use a spatula to spread it evenly.
- Set your oven to the bread proofing setting. Allow the bread to rise in the oven for 3-4 hours or until it rises to the top of the baking tin. If your oven does not have this setting, let the oven preheat to its lowest temperature while you make the dough. Turn the oven off and allow the dough to rise in the oven. OR, cover the dough with a kitchen towel or plastic and allow to rise at room temperature until the dough has risen slightly higher than the top rim of the baking tin. This can take anywhere from 6-12 hours depending on the temperature of your kitchen.
Bake
- Remove the dough from the oven. Turn the oven on to 375°F (190°C). When the oven has come to temperature, score the top of the dough with a razor or sharp knife. Bake for 60 minutes.
- Remove the bread from the baking pan and parchment paper immediately. If you do not remove the parchment paper, the bottom of the bread will become soggy. Allow the bread to cool on a cooling rack completely before cutting.
- Store the bread at room temperature in a closed container for up to 3 days. Or freeze for up to 3 months.

I use the King Arthur flower and left out the additional xanthem gum because I knew the psyllium husk would be enough. Turned out really well but still not getting a good rise over the top of the loaf pan. Wondered if you have any tips? Thank you!
First time baking bread & it was fairly successful for my first try! I omitted the flax seed because I didn’t have it on hand but otherwise, followed the recipe and weighed everything. I proofed uncovered in a Dutch oven for 3 hours and the loaf definitely was a little underproofed. I will do the full 4 next time and probably cover it. Otherwise the flavor is really good and texture is not bad, just more dense and chewy which gluten free bread is normally that way anyway. Thanks for all the great recipes & resources!
I am so proud to be making GF bread without yeast! Thank you for this recipe! I made a successful one with just the King Arthur 1:1 flour, my starter is also fed with that, not brown rice flour. Worked great!
I am desperate to try an inclusion loaf. Have you ever added different flavors/ingredients to this dough? Like cinnamon/raisin or something savory?
Thank you!
Hi Sarah, thank you so much! I would add them in after you mixed the dough and work them in.
Although I have yet to try try it. It was enjoyed by the person for whom I made it. Even a non-celiac enjoyed the taste and texture as did the celiacs. This recipe is tasty for everyone and I look forward to trying it someday!!
I have made reg sourdough and Iam trying GF now. Just wanted some input on why a stretch and fold isn’t done to GF sourdough? Do u put it in the pan to rise for its structure?
Yes
Rising now before bake off. I like the lightness of this dough and was wondering if it can be adapted to be baked without a pan.
also instead of all brown rice flour a blend of Brown Rice, Sorgum, Millet?
Thanks

A newbie with Gluten Free and Sourdough!
Hi Tanya, this recipe doesn't hold it shape well so it must be baked in the pan for the sides to be supported. I'm sure it would work with all brown rice flour.
Hello thanks for this recipe. I made this bread yesterday it was delicious, but today it tastes a little bitter. Do you know what cause this? Is somebody experiencing the same issue?
Hi, I’m excited to try your gluten free sourdough recipe. I have some questions, tho. I have an autoimmune disease and can’t tolerate any grain flour. But I can tolerate buckwheat, cassava, garbanzo flours. My questions are: do I use the same ratio of flour with these flours as the brown rice recipe calls for? Is the ratio of tapioca powder & arrowroot the same, too? And can I replace the xanthum gum with chia seeds & at the same ratio?
Brown rice flour is more grainy & light than cassava & garbanzo flours are. And buckwheat is more sticky/stringy when moist.
I’m excited to have good bread to eat and looking forward to trying this recipe. Thank you so much! I look forward to hearing from you. Vicki
Hi Vicki! Unfortunately I haven't tested this recipe with those swaps. It sounds like those swaps could possibly work so I would try it. Please let me know if you do!
Thank you!
Taste it great but the bottom is gummy and not cooked through… any helpful hints on how to make this better? Thanks!
I am getting gummy bottoms as well too. Has there been a response yet?
Hi Mary, do you remove the loaf after baking to make sure moisture doesn't form on the bottom as it is cooling?
I have made this bread twice and failed. I’m sure I’m doing something wrong. I would love some input. I have been making regular sourdough using your sandwich recipe and it is wonderful. I made the gf starter just fine but the bread turns out gummy and not cooked on the bottom. I tried cooking longer and that didn’t work. I didn’t use psyllium husks but I added extra flax seed. I struggled with the fall off the paddle step. The dough looks like yours but I added more water and it really never fell off the paddle but was smooth. If you have some input I would appreciate it!
