This keto Irish soda bread has a crunchy crust and a rustic texture. It is a simple, quick and flavourful bread that requires just 6 ingredients and 5 minutes prep time.
My friends, it is St. Patricks day tomorrow and everyone is thinking about cabbage, green desserts... and Irish soda bread!
There are many ways to make this classic bread, and recipes range from dense and dark to sweet versions that resemble a gigantic scone.
My keto soda bread is a gluten-free, grain free version of how my Irish friend Annie likes hers. It has the same rustic crumb and texture as the traditional recipe and contains the two essential ingredients: baking soda and buttermilk.
You are going to love how simple this bread is to make. There is no need for any fancy equipment. A bowl, a spatula and your hands will do!
Of course, this is such a delicious quick bread that we don't only make it for St. Paddy's day. In my opinion, it is a great everyday bread for any time of the year.
🌟 Why You'll Love This Bread
- Rustic yet fluffy texture
- Mild, nutty flavor
- Easy one bowl recipe - only 6 ingredients
- Naturally gluten-free, grain-free and high in fiber
- low carb and keto-friendly
- 3.6g net carbs per slice
Here are the ingredients you'll need:
- Almond flour - I used ground almonds, which is equivalent to regular almond flour.
- Ground flaxseed - Both brown and golden flax meal work fine. The brown flax has a nuttier taste.
- Psyllium husk powder - Psyllium is a prebiotic fiber and creates a fluffy texture in low carb bread. It is important that you use powdered psyllium and not whole psyllium husks. It should have a very fine consistency, just like flour.
- Buttermilk - This is the secret ingredient in classic Irish soda bread. It assists with the leavening of the dough. My buttermilk was fairly thick. Buttermilk contains a moderate amount of carbs. However, calculated per slice the bread is keto friendly.
- Egg - Whisk the egg well before adding it.
- Baking Soda - Also called bicarbonate of soda. It would not be soda bread without the baking soda!
- Salt - This is optional, but I added a dash sea salt to the dough for a better flavor.
(This section contains step by step instructions and photos that show how to make this recipe. Find the recipe card with ingredient amounts and nutritional information at the bottom of the post.)
Step 1: In a large mixing bowl, stir together the dry ingredients.
Step 2: Make a hollow in the centre and add the beaten egg and the buttermilk. Combine with a spatula, then knead the dough until smooth.
Step 3: Form a dough ball, then let it rest for 10 minutes. During this time, the flax and psyllium absorb the moisture.
Step 4: Form a loaf and put it on a baking sheet lined with parchment paper. Score the top with a knife. Bake in the oven until golden brown and you can insert a toothpick without crumbs sticking.
Let the bread cool fully on a wire rack before slicing. It firms up as it cools.
Here are a few things that I have learned from baking many, many loaves of low carb bread over the years:
For a better rise and a light crumb texture, it is helpful if all wet ingredients (the buttermilk and the egg) are room temperature.
Check the bread after 30 minutes in the oven. Once the top is golden, cover it loosely with aluminium foil for the remainder of the baking time. This way, the inside of the bread can cook fully without the crust over-browning.
I mentioned above already that the psyllium needs to be powdered. Whole psyllium husk looks like tiny sticks, and it is easy to mistake it for powder. We are looking for a fine powder that has the consistency of wheat flour or cornstarch.
Soda bread is a quick bread that is made with baking soda instead of baking powder or yeast. The traditional Irish soda bread is not Keto-friendly because it contains wheat flour.
Some psyllium husk brands take on a purple hue when baked. This does not affect the taste. I have used BonPom, Green Origins and Just Natural without issues. The NOW brand is also fine.
Substitute the almond flour with a blend of sunflower seed flour and sesame seed flour for a nut-free version.
No, this does not work.
I like my soda bread savoury. However, you can also make a sweet version! Simply add 1-2 tablespoons of powdered sweetener of your choice (allulose would be perfect). Instead of currants, stir in a handful of sugar-free dried cranberries.
Another option is to add crunch: chopped walnuts, pecans or seeds such as pumpkin seeds or sunflower seeds. Add these into the dough or sprinkle over the top.
If you really, really want to avoid buttermilk, I suggest that you use full fat plain yogurt or Greek yogurt instead. Another option would be to replace the buttermilk with ¼ cup or 60 ml heavy cream, ¼ cup or 60 ml almond milk and 1 tablespoon apple cider vinegar. Knead the dough and add more almond milk if required.
Dairy-free: For a dairy-free version, use coconut yogurt.
My favourite way of eating low carb Irish soda bread is simple: toasted and spread with a generous amount of butter.
For breakfast, it is also delicious with sweet toppings such as sugar free strawberry jam or lemon curd. Or make a quick sandwich at lunchtime by topping it with anything from ham and cheese to tuna salad or egg salad.
The bread is also fabulous as a side to hearty soups such as my butternut squash soup.
Refrigerator: Store the bread in an airtight container in the fridge for up to 5 days.
Freezer: I love freezing bread, because then I can just pop a slice in the toaster when I feel like it. You can freeze it pre-sliced for up to 3 months.

This is absolutely the best recipe for a low carb bread I've ever made. Unlike most other keto breads it's not eggy and actually tastes like soda bread. I didn't have any buttermilk so I used half a cup of full fat Greek yogurt mixed with a quarter cup of milk.
Hi, does it have to be ground flaxseed I only have the normal one….
Yes, the flaxseed needs to be ground. It helps give stability and texture to the bread. If you have whole flax seeds, you can grind them at home in a food processor.
Good structure and taste. Heavy, though and I wonder if " 2 eggs separated, whip whites until stiff and fold dough immediately into whites before the 10 min rest" would make for a better rise. I'll try it again. Thank you for the recipe. (PS, I used the full fat yogurt variation).
Stiff egg whites would probably make the bread fluffier and the texture a little lighter.
One of the best Keto/Low Carb breads I have tried! I substituted a half cup of heavy whipping cream and 1/4 cup of water with 1 Tbsp Apple Cider Vinegar for the Buttermilk. My Husband, who still eats regular bread, kept asking if I was teasing him that this was a Keto Bread! He already wants me to make more 🙂
We had it with some Irish Cheddar as part of our Saint Patrick's Day celebration. Thank you so much for this recipe!
Wow, this bread is delicious! It rose like a dream and looks just like yours. I think next time I will make two loaves. Thank you for another great recipe.
Could I make this into individual rolls. If so how long would I need to cook them for
Of course. If you made 4 rolls, you'd probably bake them for around 30-35 minutes. This is a guesstimate - do check whether they are done with a toothpick.
Love it. Quick and easy to make and delicious to eat.
Just made this and I love it. Great flavour and texture. Thank you so much.
I have to be egg free due to allergy. Is there a way I can use some kind of egg substitute?
I would try a flax egg.
Hi, this looks great! Do you think it would be possible to swap the buttermilk for a dairy-free alternative? If yes, what do you think would work best? Thanks!
I would try a coconut yoghurt.
