🥘 Ingredients
This delicious buckwheat sourdough bread recipe is naturally vegan and can easily be made into gluten-free buckwheat sourdough with a few simple swaps. The best part is that you probably already have most of the ingredients at home!

Buckwheat Flour: You can find buckwheat flour at most grocery stores where you would find other alternative bread flours like brown rice flour, millet flour, and oat flour. If you want to make your own flour using whole-grain buckwheat groats, simply toss them into a food processor or blender and pulse until a fine flour forms. (Learn More: How To Cook Buckwheat).
All-Purpose Flour: To ensure that our buckwheat sourdough is fluffy rather than dense, you’ll need to use a combination of buckwheat and all-purpose flour or gluten-free flour. I’ve done lots of recipe testing to come up with the ideal ratio, so you can trust that this is the perfect combination for the best sourdough buckwheat bread.
Whole Wheat Flour: While you could simply combine buckwheat and all-purpose flour, I like to add whole-wheat flour into the mix for added nutrients. By using both regular all-purpose flour and whole grain flour, you wind up with bread that tastes amazing and is packed with fiber and other beneficial nutrients.
Sourdough Starter: A fermented dough made with wild yeast and lactobacilli, sourdough starter is essential for making any sourdough bread recipe rise. You can often find it at health food stores and bakeries, but many people choose to make their own sourdough starter instead. Feel free to use a gluten-free sourdough starter if desired. Save any leftover starter for future sourdough recipes. (PS -fermented buckwheat bread is great for digestion!)
Coconut Sugar: You only need a small amount of coconut sugar to enhance the natural flavors of this sourdough bread with buckwheat flour. If you can’t find coconut sugar or want to try something else, you can use maple syrup or brown sugar instead.
📖 Variations
There are plenty of tasty ways to customize this buckwheat sourdough loaf and make it your own. Below are some of my favorite options to try out!
- Spreads: Try slathering a spoonful of your favorite spread atop a slice. Some of my top picks include mashed avocado, nut butter, cream cheese, hummus, fruit compote, and vegan Nutella.
- Toppings: If you want to jazz up your sourdough loaf with some savory toppings, try using rolled oats, whole buckwheat, pumpkin seed butter, sesame seeds, or flaky sea salt.
- Gluten-Free Buckwheat Sourdough Bread: You can easily turn this dish into gluten-free bread by swapping out the all-purpose flour and whole-wheat flour with gluten-free flour. Make sure to also use a gluten-free starter.
- Spelt and Buckwheat Sourdough Bread: Spelt flour is light and airy with nutty flavors and a subtle sweetness. If you want to add it to this recipe, you can use it in place of the whole-wheat flour.
- Rye Buckwheat Sourdough Bread: Rye is incredibly nutrient-dense, so it would make a great addition to this recipe. I wouldn’t recommend using it to replace the all-purpose flour, but you can use it instead of whole-wheat flour or use equal parts of both.
🔪 Instructions
Let’s break down how to make this whole grain buckwheat flour sourdough bread recipe. You only need around 10 minutes of prep time, a few hours to let the dough rise, and under an hour in the oven!
Whisk Bread Flours: In a medium bowl whisk together the flour, sugar, and salt.

Form Dough: To the dry ingredients add the sourdough starter and 1 cup of warm water. Mix until combined well. Add the remaining water and mix until well incorporated.

Knead Dough: Knead dough on a floured surface until smooth.

Let Dough Rest: Line a large bowl with a clean tea towel and dust with a sprinkle of flour. Place the bread dough into the bowl and cover. Rest in a warm place for 2-4 hours to allow the dough to rise slightly.

Prepare Oven, Prep Dough to Bake: Heat the oven to 400 degrees F / 200 C, along with a dutch oven for 20 minutes before cooking the bread. After the dough has rested for at least 2 hours, uncover the top of the dough and place a piece of parchment paper over it. Gently turn the bowl upside down to remove the dough onto your work surface. Score the dough with a sharp knife or a bread lame.

Bake Bread: Place the dough into the hot dutch oven, cover and cook for 20 minutes. Remove the cover and cook for another 25 minutes. Finish cooking for another 10 minutes either directly on the shelf rails or a baking tray. The sourdough bread should be ready when it sounds hollow when tapped and the outside is crusty.

Slice and Serve: Let the loaf cool on a cooling rack overnight. Once cooled completely, slice and enjoy.

❓Recipe FAQs
You can serve this sourdough with buckwheat flour any way you would serve regular sourdough bread! I love stuffing my favorite sandwich fillings in between two slices of toasted sourdough and pairing it with fresh veggies or crackers. You can also serve it alongside soups or salads or even turn it into toast! You can’t really go wrong no matter how you serve this bread.
You can store your loaf of bread at room temperature for up to 3-4 days. It’s best when enjoyed during the first week, but you can freeze your bread to preserve for longer if needed. Make sure to let the bread cool completely before transferring it to an airtight container or plastic bag.
Yes! Unlike regular white flour, buckwheat flour is naturally gluten-free. It’s also a complete protein, meaning it contains all eight essential amino acids. Buckwheat flour is also way less processed than white flour and is packed with fiber, protein, and nutrients.
I wouldn’t recommend swapping out all-purpose flour for buckwheat flour. This type of flour should be used in conjunction with regular bread flour, not as an alternative. The result would likely come out incredibly dense if you tried to make a 1:1 swap. Instead, I recommend substituting only 25 percent of wheat flour for buckwheat flour in a bread recipe.

I’m still new to sourdough baking and I’m wondering… is the sugar absolutely necessary? We’re trying to reduce glycemic spike as much as possible. I wonder if it is added for flavor or if it is needed for the fermentation? Thank you!
Hi Hilary! While it’s not 100% necessary, the sugar does play an active role in this recipe in a few ways:
1) It helps with the overall rise of the bread and the rising time
2) It tenderizes the crumb, so it helps make the bread softer
3) It increases the browning of the crust
You can certainly try this without sugar and it will probably still turn out ok, but it may not taste as soft / light as it would with the sugar! Hope that helps!
