Whole Grain Gluten-Free Sourdough Bread

This summer, myself and a group of fellow nutrition students and alums are reading Deep Nutrition for a book club we’ve started. The theme of the book is about the benefits of traditional diets, somewhat in the Weston Price tradition, for optimal health. I cannot yet comment on what I think of the book as I haven’t read enough to have a strong opinion, but the idea of eating more in the traditional style with its emphasis on whole foods as close to the source and as untouched as possible from chemicals and the like has been a major theme in my nutritional courses over the past two years. It is also a viewpoint I adopted years ago when figuring out how to truly recover from the diet culture I was immersed in and which was contributing to my eating disorder behaviors around foods. In my classes, we’ve also delved a lot into the need for promoting gut health, since a healthy, happily functioning gut can be thought of as the foundation to health in the body and mind far beyond our digestive region. This also happens to be a topic that is near and dear to me because it’s one of my main health struggles.

As I’ve mentioned before, The three major nutritional practices that promote gut health are eating more fiber, eating more fermented foods, and reducing sugar and refined carbohydrate intake.

Last summer, after a particularly rocky winter and an autoimmune lab marker coming back positive, I began a very focused fine-tuning of my diet and lifestyle, in relation to improving gut health and my reaction to stress, since both strongly contribute to autoimmune conditions. As part of that process, I began a return to making sourdough.

Sourdough, as the name suggests, is a traditional fermentation process where wild yeasts ferment the flours, making them easier to digest because the yeasts create lactic acid, and which then break down anti-nutrients that plants make to protect themselves, such as phytates and lectins. These anti-nutrients block mineral absorption and the resulting sourdough can contain a lot more readily absorbable nutrients than the original unfermented flours or grains. Additionally, the process of fermentation more generally makes all the proteins in the bread easier to digest, and it is the protein that is usually causing an inflammatory reaction for those with GI issues like intestinal permeability, malabsorption, celiac disease, and other autoimmune conditions. Due to our hectic lifestyles and often very non-whole-foods diets, many, many of us have at least some of these symptoms and/or diagnoses that could be improved by adding more fermented foods, in addition to the other two gut health promoting practices of eating more fiber and reducing sugar and refined carbohydrates.

For someone that is very sensitive to gluten like me, there’s also good news from eating gluten-free sourdough, as there are research indications that the fermentation process involved in making traditionally fermented gluten-free bread reduces the release of inflammatory compounds within the gut for someone who has recently adopted a gluten-free diet due to a celiac diagnosis, whereas consuming other types of gluten-free bread did not reduce these inflammatory responses1.

Maybe it’s the tea-drinking, sweater-garbed, sourdough-baking wise grandmother in me, but I can’t help but think, of course, to that news. It simply seems that our systems recognize and respond better to the more traditionally made foods like sourdough. Whenever I have a GI flare-up these days, I definitely try to put extra focus on avoiding those refined gluten-free products and even whole grains that weren’t cooked really well, and emphasize sourdough for my grain consumption. I’m finding this helps me return to balance more quickly. For someone that doesn’t react so strongly to gluten, consuming sourdough instead of regularly-baked bread still contributes all the positive benefits I mentioned above about keeping the gut happy and increasing nutrient absorption.

So now, after more than a year of refining my gluten-free sourdough method, I have a recipe I feel good about sharing!

Whole Grain Gluten Free Sourdough Bread, makes 1 sandwich/toast loaf
– Adapted from Baking MagiqueWholehearted Eats, and with tips from Bad Hunter Stories.
– I have a 100% buckwheat starter that I began using this formula. I did not add any outside culture, but simply created it from the wild yeasts in my home. This meant it took a little longer for the starter to get good and active initially.
– For the buckwheat and oats, I often start with whole grains which I grind in my coffee/spice grinder each time I bake and feed the starter.
– I only make this using a kitchen scale rather than measuring cups, and I’ve found I can interchange the flours, by weight, using this method.
– Using slightly different flours along with the the outside weather will result in needing to change the amount of water. Err on the side of having a fairly moist dough that still comes together. 

80 g brown rice flour
140 g cold buckwheat sourdough starter
110 g water
————–
350 g water at room temperature + more as necessary to reach the desired consistency
20 g psyllium husk
10 g ground flax seeds
————–
60 g of each
– sorghum flour
– oat flour
– buckwheat flour
– millet flour
– teff flour
24 g / 2 Tbs. sugar or honey
1 tsp. sea salt

  • In the evening: Mix brown rice flour, sourdough starter and water in a bowl and cover with a clean kitchen towel. Let sit overnight (about 8-12 hours) in a warm and non-drafty place.
  • In the morning: Mix water, psyllium husk and ground flaxseeds in a bowl and whisk until a thick gel forms. Set aside.
  • In a separate bowl mix all of the dry ingredients.
  • Add the sourdough starter that you made the night before to the wet ingredients and mix.
  • Add the wet mixture to the dry ingredients and stir with a wooden spoon until the flour is fully incorporated. Add a small amount of filtered water, if needed, to arrive at a moist ball of dough.
  • Line a loaf pan with parchment and dump the dough into the pan, smoothing it out into a loaf shape and leveling it into all the corners. Cover with the clean kitchen towel or plastic bag and put in a warm place away from drafts. Allow to rise for 4-6 hours. This will depend on your kitchen warmth. Mine tends to stay cool so I err on the side of 6 to even 6 1/2 hours usually.
  • Preheat the oven to 500°F/260°C. Once the oven’s hot, remove the towel or bag from the loaf, and score the top with one or two good slashes with a sharp knife.
  • Put the loaf in the oven and turn the temperature down to 450°F/230°C. Bake for 50 minutes or until the internal temperature reaches a little over 200°F/90°C.
  • Let the loaf cool on a wire rack for at least an hour, before slicing.

    1. Thanks Alison! Yep to all of that!! It’s taken me a long time to arrive at a gluten-free recipe that has the right texture, no questionable ingredients or eggs, rises enough, etc. Like most sourdoughs, I’ve noticed successive loaves tend to get better as my ability to make small adjustments in moisture, rising time, etc. due to the weather or microclimate improve, but this is the recipe formula that has been consistently yielding a good quality loaf for the past few months!
