This 1-Ingredient Gluten-Free Buckwheat Bread recipe is an absolute game-changer! I’ve been making it every single week since early 2022, and it never disappoints!

Ingredient Notes

  • Hulled Raw Buckwheat: Buckwheat groats (or kernels) are the hulled seeds of the buckwheat plant. Despite their name containing the word “wheat,” buckwheat is actually gluten-free and makes for a fantastic bread ingredient. These groats are a staple in many Eastern European and Asian cuisines, known for their nutty flavor and versatile use. This Healthy Buckwheat Bread Recipe is a testament to that.
  • Water: Tap water is fine to use depending on your location, if the water is heavily chlorinated in your area, you should choose filtered water, as chlorine will impact the fermentation.
  • Salt: Either sea salt flakes or table salt works fine. The salt enhances the natural flavor of the buckwheat.
  • Poppy and Sesame Seeds: Adds a delightful crunch and visual appeal to the bread. They are optional but highly recommended for an extra touch of flavor and texture. You can top it with any seeds you like.

IMPORTANT: Use ONLY hulled, non-roasted buckwheat for this recipe. Buckwheat flour, unhulled buckwheat, activated buckwheat, or roasted buckwheat will not work in this recipe.

Why You’ll Love This 1-Ingredient Buckwheat Bread Recipe

  • Delicious and Dense: It’s absolutely delicious, with a dense, satisfying texture, and gets even better when toasted! Fermentation not only enhances the flavor, but it can improve the bioavailability of certain nutrients in foods. Specifically, the fermentation process can reduce levels of phytic acid, which is known to bind some minerals and reduce their absorption. By breaking down phytic acid, fermentation can make minerals like iron, zinc, and magnesium more available for absorption by the body.
  • So Easy: Although the fermentation process takes a bit of time, this recipe is very hands-off and only requires about 10 minutes of actual work. If you use the right kind of buckwheat, a high-speed blender, and follow the instructions, this simple, yeast-free bread recipe is practically foolproof.
  • Cost-effective: Good quality, nourishing, gluten-free bread can be quite expensive where we live, often costing around $15 AUD (~ $9.80 USD), whereas this Gluten-Free Buckwheat Bread comes in at under $3.50 AUD (~ $2.30 USD), even when using organic hulled buckwheat.
  • Meal-Prep: Easy to prep in advance and can be frozen. I usually keep half fresh, wrapped in a clean kitchen cloth, to consume in the next few days and slice and freeze the rest. Toast when ready to eat, and it’s as good as fresh! This way, you can toast a piece whenever you crave some delicious bread.

What Are the Health Benefits of Buckwheat?

  • Buckwheat is highly nutritious, offering a source of fiber and essential minerals, especially magnesium. It’s also packed with antioxidants, particularly rutin, which supports blood vessel health. Despite its name, buckwheat is naturally gluten-free, making it suitable for those with gluten intolerance or celiac disease.
  • Buckwheat’s low to medium glycemic index makes it a good choice for those managing blood sugar levels. Plus, its high fiber content aids in digestion.
  • Like amaranth or quinoa, these whole grain groats can be cooked like rice or oats, making them a fantastic ingredient for various dishes. From traditional porridge and pilafs to modern salads and even as a rice substitute, buckwheat is incredibly adaptable. It’s also used in making buckwheat flour, a popular alternative for gluten-free baking. We use buckwheat flour to make these High-Protein Buckwheat Pancakes with Blueberry Syrup, and they’re so fluffy and delicious!

Step By Step Instructions

Rinse the hulled buckwheat kernels under cold water until clear. After rinsing, soak 17.5 oz (2.6 cups or 500g) of buckwheat in cold water in a large bowl, fully submerged, and cover with a clean cloth for 6 to 7 hours.

Once soaked, drain the remaining water but do not rinse.

Transfer to a blender with 6.8 fl oz (0.9 cups or 200 ml) of water and ¼ tsp salt. Blend, starting at low speed and slowly increasing, until you get a very smooth texture without any pieces left. Pour the blended buckwheat mixture back into the bowl.

Cover it again and let it sit at room temperature for 12 to 24 hours to ferment. Please check the fermentation table below to confirm the time required based on your current climate.

When you’re ready to bake, preheat your oven to 350 °F. Line a loaf pan with baking paper and pour the fermented buckwheat dough into the pan. If you’d like, sprinkle the top with 2 tsp of poppy and sesame seeds (or whichever toppings you’d like).

Bake the bread in the preheated oven for 90 minutes. The bread should be golden brown and firm to the touch.

Allow the bread to cool down before slicing. This makes it easier to cut and improves the texture. Enjoy your homemade, nourishing, gluten-free buckwheat bread!

Servings 15


  • 17.6 oz hulled buckwheat kernels (2.6 cups) (MUST be hulled, raw buckwheat kernels/groats for this recipe to work)
  • 6.8 fl oz water (0.9 cups)
  • ¼ tsp sea salt flakes
  • 2 tsp poppy and sesame seeds (optional)


  • Rinse the hulled raw buckwheat kernels under cold water until the water runs clear. This ensures that any dust or impurities are removed.
  • Transfer the rinsed buckwheat to a large bowl. Cover the kernels with a large volume of cold water, ensuring they are fully submerged. Cover the bowl with a clean cloth and let it sit for 6 to 7 hours.
  • Once soaked, drain the water, but do not rinse the buckwheat kernels. Transfer them to a blender with 6.8 fl oz (0.9 cups/200 ml) water and the salt. Blend, starting at low speed and slowly increasing until you get a very smooth texture without any bits and pieces of buckwheat remaining.
  • Pour the blended buckwheat batter back into the bowl. Cover it again and let it sit at room temperature for 12 to 24 hours (please see notes to determine how long you should leave it to ferment based on your climate). Once fermented, you will notice a very slight rise, and the mixture should be slightly bubbly inside.
  • When you're ready to bake, preheat your oven to 350 °F. While the oven is heating, prepare a loaf pan by lining it with baking paper.
  • Pour the fermented buckwheat dough into the prepared loaf pan. If using, sprinkle the top with poppy and sesame seeds.
  • Bake the bread in the preheated oven for 90 minutes.
  • Remove the bread from the loaf pan and let it cool completely before slicing. This is important to get the best texture. Now, enjoy your homemade, healthy buckwheat bread!

How long should I ferment the bread?

This depends on your location and current temperature, as fermentation is temperature-dependent. Colder climates will need a longer fermentation, and it can be shortened as the temperatures rise during the year, as the heat accelerates fermentation.

For colder climates (winter, with an indoor temperature of approximately 70°F (20°C)), ferment for 24 hours. If your indoor temperature is below 70°F (20°C), you can try leaving the batter in the warmest place in your house to give it the best chance of fermenting.

For warmer climates (summer with an indoor temperature between 75 – 85°F (25 – 30°C), I’d recommend starting with 12 hours of fermentation. We have tested this recipe in both summer and winter in Sydney Australia, which remains a pretty temperate climate. Depending on where you are in the world there might be a little bit of experimenting to figure out the perfect timing, but I promise it’s well worth it!

Some people from our IG community in more exotic locations with hotter and more humid climates have reported good results with as little as 6 hours of fermentation. If this is the case for you, start with 6 hours of fermentation and monitor the dough to avoid over-fermenting. The dough will have a slightly raised appearance and be a little bubbly inside when ready to eat.

There is a smell to my bread. Is that normal?

Yes, fermentation does have a specific smell, which will be reduced when baking. Over soaking the buckwhat will result in a unpleasant smell, so keep it to 6-7 hours soaking time on the kitchen counter or in the fridge for extremely hot and humid climate.

Is this buckwheat bread recipe gluten-free?

Yes, it’s completely gluten-free.

Can I use a substitute for buckwheat in this buckwheat bread?

This recipe only works with HULLED, NON-ROASTED buckwheat groats.

Can I use buckwheat flour?

Unfortunately, it won’t work for this recipe.

How long does this bread last?

It stays fresh for up to 3 days in a sealed container or wrapped in a kitchen cloth. I like to slice half straight away and freeze it to make the most of it.

Can I freeze this bread?

Yes, slice and freeze for up to a month.

Can I use other ingredients in this bread?

While the base recipe only requires one ingredient and cannot be swapped, you can certainly add other ingredients to customize the bread to your liking. Consider adding seeds, nuts, dried fruits such as dates, or spices for additional flavor and texture. I love a mix of black olives (pitted!), rosemary, and walnuts! Just remember to add these extras after the fermentation process and before baking. I however recommend tasting the bread without any ad-ons first, to make sure you have the perfect fermentation time, and know what to expect in terms of taste and consistency. Then, feel free to experiment with these additional ingredients to achieve your desired balance of flavor and texture.

Can I skip the salt?

You can; it will still work, but I find it provides a much-needed touch to the flavor of the bread.

Does the dough rise after fermentation?

It has a very slight rise – it’s quite different from yeast fermentation. Don’t worry if it looks like your dough hasn’t risen much – it will still work.

I’ve left my buckwheat to soak for more than 7 hours. What should I do?

If that’s the case, I would recommend rinsing the buckwheat as it might develop a bit of a smell otherwise. It’s still fine to consume. We recommend not to rinse in our recipe, as when we tested it, we got a slightly nicer texture once baked, but it still worked when rinsed.

Should I soak the buckwheat in the fridge or on the counter?

They are fine to leave on the counter. However, if it’s too hot or humid where you are, you can place them in the fridge. Leave out of the fridge for the fermentation part.

Can I slice my bread straight away when it’s out of the oven?

If you slice it before it cools down, it will just have a mushier texture.

My bread didn’t rise – what can I do differently?

If your indoor temperature is lower than the one we have mentioned, it might need to be fermented longer. Use filtered water if the water in your area contains a lot of chlorine, as this will negatively impact fermentation. Someone in the community also mentioned fermenting the dough directly in the loaf pan as a tip to get it to rise even more.

  1. Sarah, thank you for this recipe! I tried it for the first time last week and it was easy to make, plus the texture was great. I did want more flavor though, so I’m planning to blend rosemary, caraway, or another herb directly into the mixture—do you think that will work? Also, could I add yeast, baking soda, or baking powder at a particular stage to make it rise even more, or will that mess up the loaf’s chemistry? It might just have to be a squat, dense loaf, but I wanted to check. Thank you for your time and your recipes!4 stars

    1. Hey Ben, you can absolutely add spices to the blended step, although I have not tried to blend rosemary in it yet, so please let me know if you give that a go! I have mixed rosemary leaves, and black olives after the fermentation step and that was delicious.

      I have not tried adding any yeast or powder, how long did you let your bread ferment and what was the temp in your kitchen at the time if you remember? Increasing the time or temperature when fermenting impacts the density of the bread a lot.

      Thank you so much for your lovely comment 💚

  2. I love this bread! I made my second loaf with extra salt and a tablespoon of honey (I blended the honey when blending the oats). The bread turned out perfectly the second time. I think this recipe would make perfect bagels, as it is quite dense, so I will buy doughnut molds. I just do not know how long to bake it.5 stars

    1. Hey Jasmine, so happy you liked it! I love this idea of turning it into little bagels, I’m not sure of the exact timing but I would probably start with 1/3 of the time of the bread and see how you go from there, please do let us know the results if you give that a go 💚

  3. I am getting ready to make this recipe and I am quite excited about it. However, my oven is not reliable and when I make bread, I usually use an Instant- read thermometer to make sure that it is done. Do you have any idea what the internal temperature of this loaf should be when it is done?5 stars

      1. I made it yesterday and put it in the oven for 90 minutes at 350°F. When it came out, it was nicely crusted & had an attractive split on top. The internal temperature was 205°F. I let it cool before I cut it and the inside was dense and soft, but not wet. I’m not sure exactly how this bread is supposed to be on the inside, but I reminded myself that the only ingredient is buckwheat so it was not going to be like other bread. I would add more salt to mine the next time, as I salted each piece a little bit after I toasted it! Could you give me a description in your own words about what the inside of the bread look like and feel like? Thank you so much. I am definitely making this again and again.5 stars

  4. I was wondering if Millet also would work. I’m going to get some Buckwheat and make the bread, but have a big bag of Millet. 🙂

  5. I was unable to cook if after 24 hours due to personal time constraints, so I put it covered in the fridge and baked it about 12 hrs later (36 hours total fermentation). It turned out perfectly!!!! Love this recipe. I couldn’t believe how wonderful this bread is.5 stars

  6. hi! Thanks for sharing this great recipe. Ive just made the bread with a 22 hs fermentation but when I cut it it looks plain without the bubbles I can see in yours. What does that means? I should have it fermented for a shorter time? or longer? can I eat it anyway or it will be too heavy? I have used raw buckwheat.
    Thanks!!5 stars

    1. Hey Celeste, it sounds like the fermentation might not have happened, you could try to ferment it for the full 24 hours next time. If you enjoy it, it’s still perfectly safe to eat, maybe chopped yp and baked in croutons if it’s a bit too dense. Just checking the buckwheat you used was hulled too?

      1. Hi Sarah, thanks a lot for your prompt reply,
        I will give it another try with 24 hs fermentation then.. maybe it was not warm enough in the room too.
        Yes, the buckwheat I’ve used was hulled. I managed to get very tiny bubbles but nothing to compare with your perfect bread! All the best.

      2. Can you allow this to ferment for greater than 24 hours? Would 36-48 hours still be safe to bake and eat?

        1. Hey Kimberly, I have not tried. Someone in the community mentioned decent results with a 36 hours ferment at very low house temp, but did say they got better results at 24 hours ferment with higher house temp. I would recommend keeping it around 24 hours to be safe 🙂

  7. My first loaf of this bread came out so well that I began baking up three loaves at a time. It freezes perfectly and it’s really handy to have ready to go in the freezer, because I eat ALOT of this bread. It toasts up so great and goes as well with yogurt as it does with soup. I like to make it with cinnamon, cardamom, and ginger right into the batter. I can see myself having this as my go-to bread recipe for the rest of my life! Thank you, Sarah!

    1. Hey Rebecca, I’m so happy to hear that, I also love keeping it in the freezer, so handy! Thank you for your lovely review 🙂

  8. I wish it can work for me. I’ve tried the recipe twice. The second time I made sure to follow everything to a T. When it baked and cooked down, there was a giant air bubble on the bottom, instead small bubbles rising inside of the “bread.”2 stars

    1. Hey Kc, does the bread turns out well except for that 1 air bubble? What is your current home temp, how long are you fermenting it for and are you fermenting it straight into the loaf pan?

  9. Hi Sarah! I just want to let you know that I made ur buckwheat bread recipe and it was phenomenal!!!! Thank you for sharing such great

  10. I tried this bread for the first time today, and LOVED it! I have an autoimmune disease and have adjusted my diet to one that is more anti-inflammatory for my body. I successfully reintroduced buckwheat a few months ago and was so excited to try this recipe, as I haven’t had bread for about 7 years. I’m looking forward to experimenting with add-on ingredients – thank you for sharing this recipe!!5 stars

    1. Hey Wendy, I’m so happy to hear you loved it and it’s helpful for your diet 💚 I’ve just posted a super easy wrap recipe using the same buckwheat which I think you might find helpful too, let me know if you try it 🙂
