If you love sourdough like I do, but you've gone on a gluten-free diet, I have some great news for you. Yes, you can make gluten-free sourdough from this Gluten-Free Sourdough Starter and there are no special ingredients to buy!
And that's not all: you can make a grain-free sourdough starter too. Read on to get all of the sourdough-loving life-changing info you've been waiting for.

I'm convinced that gluten is a big health concern for many, but I still love good bread. And while this flax bread is super tasty, there's just nothing like a good sourdough.
We LOVE the tangy flavor of sourdough, and since there are so many people who can't tolerate gluten, I've been meaning to try my hand at making gluten-free sourdough bread. I am now that much closer to my goal!
In order to prepare myself for this post, I wanted to put myself in the shoes of someone who is gluten-free.
When most people think “gluten-free,” they think that bread is no longer an option–particularly breads like sourdough.
So in order to be able to empathize with them in their struggle to balance nutrition with their allergies or intolerance… I did some “research.”
Basically, I wanted to think about what it would be like to be gluten-free.
And bread-free.
So I ate bread.
Homemade bread.
Two pieces, actually.
With a lot of butter.
And I realized how much I would miss it if I weren't able to eat bread like this on a regular basis.
I'm not trying to rub it in anyone's face – quite the contrary! I know how fortunate my family is to be able to eat whatever we want without breaking out in hives or keeling over in digestive pain.
It saddens me to imagine what it would be like to:
– not be able to walk into my kitchen and slice off a piece of bread whenever I want
– request the waiter to remove the basket of bread instead of refilling it
– worry about being sick for days because someone accidentally contaminated a cooking spoon!
I think I can understand your pain.
That's why it truly brings me joy to share with you a way to have your cake–er, bread–and eat it too.
Gluten-free sourdough, baby. Oh yeah.
Imagine capturing wild yeast out of thin air and cultivating it over a period of several days so that, without any help at all, it will magically make the dough rise and become a beautiful (and relatively inexpensive–) gluten-free loaf of bread.
It really isn't as hard as it sounds!
But it is incredibly healthy! Quite possibly the healthiest bread you can make!
Benefits of Sourdough
There are many benefits to sourdough including:
Easily Digestible
Sourdough is easier to digest than regular bread (preventing issues like indigestion, etc.)
Beneficial Bacteria
Sourdough contains the healthy gut bacteria lactobacillus (the same major player in yogurt and kefir)
Fewer Nutrient-Binding Qualities
Most of the phytic acid in sourdough is broken down, reducing the effects of nutrient-binders on other foods in your diet.
Lower Glycemic Load
Since sourdough takes longer to digest, it doesn't cause as much of a spike in blood sugar as traditional bread does.
Functions As a Prebiotic
Sourdough functions as a prebiotic, so it helps support healthy digestion.
Reduced Acrylamide
Souring the dough reduces the amount of the amino acid asparagine which is a precursor of acrylamide formation, and acrylamide is a cancer-causing ingredient found in toasted grains, including bread crusts. So with sourdough, you can enjoy your bread crust with less acrylamide.
Gluten-Free vs. Regular Sourdough
Making a gluten-free sourdough starter isn't any different than making a regular sourdough starter.
– Both start with flour and water.
– Both take a few days, and both get bubbly.
– The only real difference comes when you're ready to make sourdough bread and you have to pull out all the various types of gluten-free flour.
Gluten-free sourdough starter can be made in as little as seven days using gluten-free flour, water, and a medium-sized bowl. I personally have successfully made gluten-free sourdough starter with brown rice flour, but I've read others have had success with white rice flour, teff flour, sorghum flour, or even a gluten-free all-purpose blend.
Typically, in the same way that using a blend of alternative sweeteners will work best when substituting for sugar, using a variety of flours will work best for your gluten-free sourdough.
Is Sourdough Gluten-free?
While many think that sourdough is already gluten-free, here are the facts.
I have seen this argument many times. People claim that white flour has no gluten in it since all of the gluten is in the hull, and that whole grain flour sourdough bread is gluten-free since the enzymes break down the gluten.
Sadly, that is not the case.
White flour has between 8-11% gluten so all the gluten is not in the outer hull that is sifted away.
Not enough of the gluten is broken down by the fermentation process. The definition of gluten-free is 20ppm or less. Sourdough is known to have 2000 ppm of gluten. Regular bread has 80000 in many instances, so 2000 is less, but it's not gluten-free.
Please take care that if you need to avoid gluten that avoid traditional sourdough.
Grain-Free & Paleo Options
Since this post was published, several readers have asked if you can make sourdough starters without grains. Well, the good news is: YES YOU CAN! There are 2 schools of thought on this, however.
Some say that you need at least 1/3 of your flours to be a starch: tapioca, arrowroot, or maybe cassava flour. Starch is what feeds the yeast so that is the reason behind this requirement. If using coconut flour, however, you will need to add more water to the starter. Instead of a close to 1:1 ratio, for every cup of coconut flour that you use, you will need to use about 1 2/3 cups of water.
Coconut Flour Sourdough Starter
Can you make a starter from only coconut flour? Good question.
There are some who say that you can, while others say that you cannot.
The information is in the recipe card so you can try it, but you might need to add some sauerkraut juice for it to work and not sure what kind of recipes you can make with it. From what I've read, this really doesn't turn out that well, but I know that some people are really desperate to make recipes that will work for them, even if they don't taste amazing, so I'm leaving this option here for you to experiment.
Sourdough Starter from Only Nuts / Nut Flours
You can make sourdough starter from nuts and likely only from nut flours, but you will need to add a fermented medium, like sauerkraut, to the starter.

Gluten-Free Sourdough Recipes
The following are a variety of gluten-free sourdough bread recipes for you to experiment with.
Keep in mind that every recipe will be different, calling for different types of flour and possibly using yeast. I've included several sources so that you can find something that suits you!
- Gluten-Free Brown Rice Sourdough
- Artisan Style Sourdough
- Sourdough Bread Boule
- Rustic Gluten-Free Sourdough
- Bread Srsly's Sourdough
- An excellent bread recipe, plus recipe adaptations in Sourdough A to Z by GNOWFGLINS
- Bread Machine Sourdough – note that you can try to adapt regular recipes to the bread machine, but here's one that is done for you.
Any of these recipes would be great topped with butter or Homemade Nut Butter. Mmmmmm.
Grain-free Sourdough Recipes
Here are some sourdough recipe for you to try after you have your sourdough starter ready to go:
There are other grain-free sourdough recipes out there but those that call for a nut base will need a different method for fermenting due to them needing something to jump start it (like sauerkraut) rather than just the starch. This recipe is an example of that. I hope to have some additional recipes for you in the future.
What You'll Need
To make gluten-free sourdough starter, you'll need:
- gluten-free flour (some grain-free options will work)
- water
- a jar (or bowl)
- a cover
- something to secure the cover

How to Make the Starter
Following are some images and some brief info about how to do this. Full instructions are below.

Combine flour (whatever gluten-free or grain-free flour or gluten-free flour blend you like) and water.


Feed the Starter for several days.

When your sponge looks like photo #8, you're ready to make sourdough bread!
Recipe Notes and Substitutions
- Ingredient Amounts: The amounts we give in the ingredient list are the amounts you will need if you only feed the starter twice a day, which is the least number of times you should feed it. So if you feed it more often, you will of course need more flour and water.
- Flour: Gluten-free flour blends (just like with alternative sweeteners like stevia) tend to work best when used in conjunction with others. So it's best not to try to make this sourdough starter or sourdough with only 1 gluten-free flour. Personally, I recommend using a blend of flours. As you can read in this gluten-free baking tips post, using a blend of flours tends to make baked goods turn out better when using alternative flours.
- Grain-Free: For a Paleo Sourdough Starter or AIP Sourdough Starter, just use organic cassava flour or organic tiger nut flour in place of the gluten-free grain flours.
Troubleshooting Your Starter
Here are three of the most common things that you might notice while watching your starter and what they mean:
Too Much Starter
If after a few days the starter begins to outgrow the bowl, pour some off to make a batch of sourdough pancakes. Leave at least 1/2 cup of starter in the bowl to continue feeding.
Liquid At the Top
Liquid may or may not collect at the surface of the starter. Either case is normal. (FYI: the liquid contains more lactobacillus and gives the bread its sourdough taste.)
No Bubbles
If you do not see bubbles at the top or at the sides of the starter, add a third feeding. Try to keep the feeding intervals equal. For example, 6am, 2pm and 10pm are all equally apart at 8 hours.
One thing you can do in this case is add one to two tablespoons of water kefir, dairy kefir, kefir whey or kombucha in place of the water for just one feeding. Since you are adding more bacteria “goodies” to the mix, you are boosting fermentation action.

FAQs
How Long Should You Feed Your Starter?
After the initial period of making the sponge, etc., your starter is officially in maintenance mode. Then you can feed it as often or as little as you like.
- At the very minimum, you can keep it in the fridge and feed it weekly. However, it's not recommended to have it in the fridge until after it's 4 weeks old.
- You can keep it on the counter and feed it daily, and use anything you don't need for recipes.
- You could feed it daily with as little as 1 tablespoon of water and flour to keep it fed but not produce a lot of starter.
How Long Can You Store Your Starter?
You can keep it for quite a while provided you feed it daily. You will, however, need to revive it when you want to use it again.
- Three and a half days before baking, remove the starter from the fridge and bring it to room temperature (let it rest for about 1/2 a day.
- Feed with equal parts flour and water.
- About 1/3 of a day later, feed the starter again.
- Once you have foam and liquid rising to the top of the starter, you can use the starter for bread. If you don't have that after 4-6 hours, keep feeding daily until you do.

Gluten-Free Sourdough Starter
Ingredients
Gluten-free Sourdough Starter
- 6 cups gluten-free or grain-free flour
- 5 1/4 cups filtered water
Coconut Flour Sourdough Starter
- 1/2 cup coconut flour
- filtered water
Instructions
Gluten-free Sourdough Starter
- Combine 1/2 cup flour (whatever gluten-free flour or gluten-free flour blend you like) and a scant 1/2 cup filtered water in a medium to large bowl.Whisk until smooth and cover the gluten free sourdough starter with a cheesecloth or clean dishtowel to allow air to circulate but prevent particles from falling in.Set the bowl in a warm area where it will not be disturbed. A kitchen counter, pantry cabinet, or patio can all be good options.
- Wait 12-24 hours.
- At least twice a day for the next six days, at regular intervals, add 1/2 cup of flour and a scant 1/2 cup of filtered water to the existing starter. Mix until smooth, and cover.This is called feeding the starter.Make sure to watch your starter carefully.
- When your gluten-free sourdough starter is very bubbly and creates a dome on top 2-3 hours after each feeding (like the above picture), you are ready to make bread. This is often called the sponge and typically it takes 5-7 days for this to happen.
- Use your starter for making the sourdough bread of choice. See above this recipe card in the post for some great options!
For Coconut Flour Starter
- Combine 1/8 cup coconut flour with 1/2 cup filtered water in a large bowl. Whisk until smooth. The mixture should be pourable but not thin.
- Cover the bowl with a plate or other air tight cover, making sure there’s at least a 1/2-inch gap of air at the top.
- Approximately every 12 hours add another 1/8 cup of coconut flour and ½ cup purified water. Stir well and cover.
- In 24–48 hours the mixture should get bubbly and smell fermented. If no bubbles form, try increasing the frequency of feedings to every 8-10 hours.
- If at any time there isn't a 1/2 inch gap at the top of the starter, move it to a larger bowl.

Hello, just wondering what do you mean by ‘scant’ 1/2 cup of filtered water. Do you mean a small amount of water?
thanks
That means “not quite” so just under 1/2 cup. Thanks!
thank you
I am using Bob’s Red Mill all purpose GF flour made with garbanzo bean. I was discouraged by the results until today when I moved my rubbermaid bowl and it started bubbling like crazy. It was bubbling so much that it looked like it was at the start of a slow boil. I was ecstatic until I noticed a furry light grey mold on the upper edge of the bowl above the starter. It was growing on the residue left from stirring the mixture. I did transfer it (avoiding the mold) to a glass bowl and fed it again. It now has a dome to it. Because of the mold do I need to give up and dump this starter?
I am not skilled at making sourdough. I’ll see if the author can respond but you might wish to ask in a sourdough group on Facebook, etc. Thanks!
Possibly this will help: (Link deleted by Whole New Mom due to it not working anymore.)
Hi,
I haven’t try your recipe yet but I have tried to mix buckwheat flour and water but on the second day there is always mold on top of my sourdough. I have been wasting a lot of flour already. I followed a recipe that was saying that we should leave the sourdough starter for 3 days and then start feeding it but I have never been able to wait until day 3..
Thanks
Hi Debra – I can’t answer questions based on another recipe. In my experience, you should feed the starter regularly starting immediately rather than wait a few days.
Thanks for the easy to follow method, it worked a treat! I have made a loaf now and it was delicious.
does the gluten free flour blend have to contain a gum?? also i feel like there are only two ingredients water and a flour blend. where does the yeast come into place…
Could you please clarify your question please? A blend does not need to have to have gums in it.
store bought yeast rises a bread too quickly, not allowing enough time for the microorganisms to do their job of changing the composition of the dough like deactivating the phytate to release the minerals (like magnesium and zinc that are lacking in yeasted breads), So in this dough that is left out for days, it catches the wild yeasts in the air as well as microbes that make this bread so nutritious and do a great job of breaking down the gluten as well as many other health benefits.
I’ve been reluctant to try making gluten free sourdough bread because the gluten is what makes it chewy and rise so nicely. I might try this. One of the most common problems in creating a sourdough culture is that they do not stir it. A new sourdough culture should be stirred at least one a day, preferably twice a day. It needs oxygen to breathe and grow.
Stir your starter, it will love you.
Thanks!!
Hi! Thx for the starter recipe. I’m not sure if the gals who were having trouble with starters “dying” got things figured out – but I’d like to share my experience. At one point I lived in a house that had mould in the walls, and I couldn’t grow sourdough because those spores contaminated the starter every time. In another house in a very remote area at high elevation I was unable to capture any viable wild yeasts and I had to use commercial yeast to get a starter going. I’ve found the most reliable way to get an excellent lively starter is to add kefir. Happy baking!
Interesting – thanks!
Does the house temperature make a difference and if so what’s a good room temperature to make it?
Yes, there is a difference based on temperature – one way will make a faster rise and the other a slower. It depends what you want and the flavor will be different as well.
I keep mine on top of the fridge- it’s supposed to be kept at 70-80 degrees. I think I read it will get killed if it is over 110.
I started my starter 6 days ago, and just baked it into GF bread using Bob’s Red Mill GF flour mix. It is SOOO good! I have a question, though–I have a bunch of the starter left, even after making 2 loaves. How long can this keep on the counter? How often do I need to “feed” it? Do I need to move it to the fridge? Thanks for your help!
Hi Shanti. Sorry I think this ended up in spam. I will contact Tiffany and see if she can respond :).
Hi, Shanti!
Did you make it with Bob’s Red Mill GF All-Purpose Flour? I’m really interested to make this because I have
A LOT of BRM All-Purpose and am trying to find recipes to use it in. Thanks!
How long can u keep starter & where to store it? Tks
Put it to the fridge,feed the starter every 5 days (max.),temperature in the fridge should be above 5 C.
Is my starter supposed to smell horrible? It started out smelling pretty yeasty, but not has a sort of rotten/winey smell to it (I think wine smells rotten and don’t drink, so can’t identify the smell exactly). It is in a bowl in the corner of my kitchen, but I can smell it just walking into the kitchen. I covered it with plastic wrap instead of a plate, could that make the difference? It looks like your pictures, a nice dome on top with a more liquid layer underneath. But I just don’t know about the smell!
Hi there. I have emailed the author to see if she can respond. Thanks and sorry for the delay. I have been swamped :).
In her sourdough recipes, Sharon A Kane recommends to cover the starter with a clean tea towel or paper towel so there is still so air circulation. Otherwise you’re growing anaerobic bacteria (no air flow) instead of aerobic bacteria.
