I’m using red onions for this gluten free onion bread to add a bit of colour to a simple 2 ingredient recipe. White or brown onions will work just as well if you prefer their flavour. Red onions also have some health benefits as they contain more antioxidants.

Linseed and flaxseed are exactly the same ingredient. Golden linseed is used here because I think it gives a nice colour but the brown linseed works just as well.

You can use chia seeds in this recipe to make gluten free chia seed onion bread if you prefer. Chia seeds go a bit grey when blended it’s not quite is pretty but it still tastes great.

Flax seeds and chia both gel up in water. I let the mixture stand for 10 minutes after blending to let the seeds soak up the onions’ moisture and this also makes them a bit easier to digest.

You can make this recipe raw vegan if you prefer by just spreading on a non-stick sheet and dehydrating for 8-10 hours. If making raw then add a tablespoon of apple cider vinegar is it make the onions a bit milder.

This onion bread is cooked in an oven to make this recipe accessible to all. The baked version does taste different to the raw as baking gives a roasted seed flavour to the gluten free bread.

I’m using non-stick paper so the onion flax bread comes away easily after being baked even without any oil. Parchment paper works just as well. Do check your paper to make sure you get one that’s got a healthy coating without added plastics.

These onion bread bites will last for a couple of days in an airtight container in the fridge. Although in practice mine only last a couple of hours before being eaten!

As this is a natural healthy recipe just full of pure ingredients there’s no stabilisers or additives so the gluten free bread can go a bit soft the next days. Firm the onion bread up by putting back in the oven for a couple of minutes.

Think of this healthy onion flax bread recipe as a basic recipe to add any twist or flourishes that you like. I like flax bread with a bit of basil and sun-dried tomatoes. If you adapt this recipe and add flavours that work well please do share the comments below so we can all enjoy.

Depending on your blender and how watery your onions are you may want to add a splash of water to help it blend. You can do this onion bread recipe in a 600w jug type blender just fine.

Don’t worry if some whole flax seeds are left in the flax bread mixture it adds texture and is a reminder to chew your food properly. If whole flax seeds to pass through your system don’t worry about it as it isn’t totally wasted as they do your digestive tract some good.

I was hoping for these 2 ingredient crackers to have a deeper red colour from the red onion after being baked. Sadly they lost just about all the colour. If you do want a deeper red colour I suggest adding half a bulb of beetroot for a vibrant deep purple-red colour! I expected this to happen but did want to keep the gluten free bread recipe as just 2 ingredients to show how simple it is to make great food with just 2 ingredients.

While baking these onion and flaxseed crackers the kitchen smells lovely with sweet onion and toasted seeds.

This flax onion bread bites are great on their own but can be a bit dry. I tend to have them with some guacamole or when I have more time with my colourful hummus trio.

I did plan on these being onion crackers but in order to get them crispy in the oven, they would need to be very thin. Although that would be great it would take so long to create a small batch of onion crackers so opted to keep them as a more substantial and flexible two ingredient onion bread.

2 Ingredient Gluten Free Onion Bread

easy onion bread recipe

Vegan flax bread recipe made from just flaxseeds and onions. This homemade gluten free onion bread recipe is eggless, gluten-free, grain free and quick to make. Suitable for vegan, keto, paleo, gluten-free and low carb diets.

Prep Time 10 minutes
Cook Time 30 minutes
Total Time 40 minutes


  • 2/3 cup / 100g Flaxseed
  • 2 medium onions, about 1 cup diced


  1. Peel the outer layer of the onion skin and freeze with veggie scraps for boiling and making stock later.
  2. Place flaxseed and onions into a blender and blend until they are broken up, a few whole flax seeds are fine.
  3. Add a bit of water if your blender struggles, once the onions and flax are blended they will start to gel up and get thick.
  4. Spread the mixture out onto a lined baking tray using a spatula. Try to get an even thickness so the onion bread cooks at the same time.
  5. I’m using a mini oven in the video but if you have a larger one spread out in the pan for thinner crispy gluten free onion bread.
  6. Score the bread using the spatula into 12-18 squares depending on how big you want your onion bread.
  7. Bake at 190C / 375f for 30-35 mins until the flax bread starts to go golden.
  8. Take onion bread out of the oven and leave to cool, as this bread is gluten free it will get firm as it cools.
  9. Turn upside down and peel off the greaseproof paper and separate the flax bread.
  10. Enjoy within 3 days and keep in an airtight container in the fridge.

    1. Thank you for the receipt. I agree the music was to slow although I did enjoy it. Please let me know who the music title and who it was by.

    2. This was so simple. When I ran out of onions I used bell pepper. I tried the bell pepper with the quinoa broccoli bread too, but it was very tasty with the flax. Your recipes are always well thought out Bastian, thank you.

    1. Glad you like the recipe. Sorry you don’t like the music. I do 5 different videos for each recipe and YouTube is slower with relaxing music. Check out my facebook, instagram or pinterest for the fast video with upbeat music!

  1. This was unexpectedly good and very satisfying! Paired it with vegan green lentil chili and it was superb! I am just concerned that I ate almost all of it in one go =)) I am going to try your bread loaf recipe next. Thank you for this simple recipe…

    1. Amazing! That’s so great to hear! I wouldn’t worry about eating it all in one go – it’s essentially a dahl in bread form.

    2. Love onion bread but why do recipe sites have to have a whole book in front of the recipe? I don’t need to hear your life story.

      1. Bastian Durward

        I hear you, but I do only chat about the food on my site! I know no one else want’s to hear about your dog and partner LOL

  2. I love the idea of this bread, but I can’t stand onion… Do you think it’s possible to use something else instead?

        1. Bastian Durward

          It depends if you’re totally replacing the onions? I would replace around the same volume of onion for beet, and Carraway seeds go so well with beet flax bread!


    Thank you for this recipe, have passed it on to my daughter to try as she cannot have gluten……

  4. Any problem with adding salt? Anyone tried making it into pizza? Can it hold a hamburger if I cut it into rounds?

    1. Bastian Durward

      No problem with salt, was just making this a 2 ingredient recipe. Yes it could hold a burger – although it’s pretty thin. Would work great as a pizza!

  5. I made this with onion last week but was a bit strong for me but loved the texture. So I just made it with jicama instead and it’s fantastic! Thank you for the recipe.

    1. Bastian Durward

      Ah sorry the onion was a bit strong – I probably add way too much! Glad to hear it turned out great with jicama – thanks for the tip

  6. I am baking it right now. I’ve been waiting for my flaxseed to be delivered by Amazon. You inspired me by your 2 ingredient recipe. Since I had a red onion, I said let me give it a try. I added a medium guacamole salsa which was too spicy for me on salads so I figured I put some for flavor. I added a pinch of salt and sesame seeds and paprika on top for color and eye appeal. Let you know in a few minutes how it came out.?

      1. It was ok. That guacamole salsa was a bit too spicy for my liking but my husband was eating it so it I guess it was good.
        I like the simplicity of only a few ingredients because I have a difficult time searching for ingredients in the store.
        So, I just made it again using 1/2 of a red onion that I sitting around. I threw in a small red pepper (not spicy) for color, added garlic powder, salt, pepper, parsley, a bit of nutritional yeast and off course the flaxseed . This time I put it in the oven since I was baking an eggplant for babaganush. Last time I used the toaster oven. I felt that I didn’t cook it enough last time. This one looks good.
        I like that it’s easy to make and also healthy. I will use it with the babaganush and hummus. Again thank you for the simple and healthy recipes.?

  7. In Thailand, it’s easier to find perilla seeds which contains high amount of omega-3, similar to flax, can I use perilla seeds in stead, but not sure if the perilla seeds gel up in water in a similar way as do flax seeds? so the uncertainty lingers if perilla seeds are fit to be made into bread????

    What kind of flax seeds should be used? ground, roasted flax seeds or whole, raw flax seeds? Do chia seeds gel up in water as well as flax seeds do?
    I have never baked anything before, so keeping my fingers crossed that it will turn out edible and OK!!!!!

    1. Hi there, I’m really not sure to be honest as I’ve never used them. A quick look online shows they might not gel up like chia or flax does. They will probably still work but I would try with 1/3 less water. Let me know how you get on!

      1. How can I share this with a private group where we are eating like this to save our kidneys? If you prefer I do not then I won’t. I thought it would get a lot of us coming over to check you out!

  8. Just so you know, whole flax is detrimental to your colon and digestive health. The whole seeds stay in your colon and small intestines and cause blockage and diverticulitis. I’m a nutritionist that has specialized in detoxing and cleansing, as well as a colonic hydrotherapist. I’ve literally watched huge pockets of flax come through my machine years after people stopped eating them whole. Cups at a time! Less important is that unlike chia, unless flax is ground you absorb none of the nutrients from it.

    1. Hi there, in this recipe the flax is ground up so am I right in thinking what you say doesn’t apply for this? Although if you look carefully in the photos there might be the odd seed not totally ground up but I was under the impression the odd seed is good for the digestive tract? Just not too many of them 🙂

      1. I have been “drinking” 3 tablespoons of soaked flax seeds for many years without any problems at all. I have had colonics during this period and, again, no problem.

  9. Listen here, I haven’t tasted it but the house smells absolutely divine. I can make it everyday just for the smell haha

  10. Zitlaly Sanchez

    Idk if I am doing something wrong but the top/outside always cooks and the middle is still goey/soft but if I leave it longer the top burns. I left it longer and the middle finally cooked but the top burnt a little. Any tips? I cook it in a small oven at 350 however morethan the 30 minutes because at 30 minutes it has not cooked through

  11. How thick do you make the bread? Would 1/4 inch be about right? Or, roughly how many inches/centimeters by how many in total? Thanks — this sounds good and I want to try it.
