Sourdough Irish soda bread is my take on a traditional Irish quick bread. Risen with the acidity of buttermilk, sourdough starter, and baking soda, it has a tender crumb similar to biscuits and is full of buttery flavor, a light sweetness, and sourdough tanginess. I love the rustic presentation of this beautiful, golden brown boule.

Irish soda bread is a type of quick bread common in Ireland, with a history that stems from necessity.
It was originally made with only four ingredients: flour, sour milk, salt, and baking soda. This made for a frugal, but filling loaf of bread.
Over time, it has been modified from the most basic ingredients to also include more modern luxuries like eggs, butter, and dried fruits. Find more fun information on the history of traditional soda bread here.
This was a fun loaf to customize for a sourdough version. It’s rustic and delicious, and the sourdough works well in combination with the buttermilk.
The starter adds great flavor, and the texture and flavor of the loaf made it a hit.
I think one of the best parts is that it’s a literal mix-and-bake recipe. If you find yourself making dinner and lacking a side, this recipe calls for basic ingredients that a frequent baker likely won’t need to run to the grocery store for.
Pantry staples are gently combined, formed into a boule, and baked in a preheated oven for about an hour.
There’s not much better than a slice of soda bread smothered with butter and honey orย homemade herb butter.ย

Tips
- If you don’t have buttermilk, you can make your own by adding a spoonful of lemon juice or white vinegar to milk. It won’t be as thick as buttermilk, but it’s a great substitute and will perform the job well.
- This recipe is pretty adaptable as far as flavor profiles go. Modify the seasonings, spices, and add-ins to fit the occasion. Easily make it sweeter or more savory. Some typical pairings are raisins and caraway seeds or cranberries and citrus zest. If you’re adding dried fruit at the end, gently fold it in with a spatula to avoid working the dough too much.
- You can use sourdough discard or active starter for this recipe. Discard will add a stronger tangy flavor to the bread than active.
- Don’t overmix the dough, but stir only until it all just comes together. Some lumps are okay, and this will keep the crumb tender.

Ingredients
All-purpose flour – Unbleached white flour is easy and gives consistent results.
Baking soda – This is the rising agent, working with the acidity of the buttermilk and starter to give the bread rise.
Salt – Sea salt adds flavor and balance.
Unsalted butter – Cold butter cut into small pieces for blending into the flour.
Buttermilk – This acidic ingredient reacts with the baking soda to rise the bread.
Egg – An egg adds more structure to this loaf.
Cane sugar – A very small amount for just a touch of sweetness.
Sourdough starter –ย You can use active starter or discard.
How to Make Sourdough Irish Soda Bread
Begin by preheating your oven to 400 degrees F. During this time, we will prepare the bread for baking, ensuring a nice, hot oven when it’s time to bake.
Prepare a baking sheet by lining it with parchment paper for easy cleanup and no sticking.
Add the flour, baking soda, and salt to your large bowl, stirring well to combine. What’s more dissatisfying than a surprising clump of baking soda?
Chop the cold butter into small pieces, then add it to the dry ingredients.
Using either your hands or a pastry blender, work the butter into the flour mixture until it becomes crumbly with the butter in pea-sized or smaller pieces.
In a separate bowl, whisk the buttermilk, egg, sugar, and sourdough starter or discard until combined.
Pour the wet ingredients into the dry, then mix somewhat tenderly until just combined. You don’t want to overmix.
Turn out the dough on a clean work surface and form it into a round loaf.ย
Place onto your prepared baking sheet, then score a deep cross or X on the top of the loaf. This will help the bread to bake more evenly (plus it’s tradition!).
Bake in the preheated oven for approximately 50-65 minutes, checking at the 30-minute mark. If the top of the bread is getting too dark, cover it loosely with a piece of aluminum foil while it finishes baking.
Bake time will depend on how wide or how tall the loaf is shaped.
Cool the loaf on a wire rack completely before slicing. Serve and enjoy!
Storage
While this fresh bread is truly best eaten the same day, you can also store it in an airtight container at room temperature for several days. Make sure it’s fully cooled first.
For longer storage, wrap the cooled loaf in plastic wrap and store it in an airtight, freezer-safe container for several months. Thaw at room temperature.
FAQ
Irish soda bread is a quick recipe, requiring no long-fermenting or long rises. The rise in this bread comes from the addition of tangy buttermilk and baking soda rather than yeast. The rise in sourdough bread comes from wild, natural yeast.ย
This comes partly from Irish superstition, but it also encourages an even bake. Round loaves are often tall in the center, which may leave the center underdone. The deep cross slashes allow heat to dristribute more evenly through the loaf. I also love the classic look of the round loaf and cross.
Raisins, currants, etc. add sweetness to soda bread and are traditional components of this classic Irish bread.
Gummy bread can arise from not baking long enough or even from cutting into fresh bread too quickly without letting it cool.

amazing bread, we all love it so much, and also so quick to make
Sandi Ruddick says
I have been making your artisan bread (and many other of your yummy sourdough treats) for awhile now. This Irish soda bread was really easy, delicious, and had a great texture! I loved how quick and easy it was. We are putting it in the heavy rotation!
Lisa Bass says
So glad you enjoy it!
Patricia says
Lovely Soda Bread recipe Lisa, I used natural yoghurt which was almost sour to make this, instead of buttermilk (reduced the quantity a bit so it wasnโt too sticky). I sprinkled rolled oats on top as we do here in Scotland.
Lisa Bass says
Yum!!
Deborah says
This is a great recipe. Easy and delicious. My husband and I have it for breakfast and lunch. Canโt go wrong with this recipe. ๐๐ป
Kathleen says
I am obsessed with this bread. It’s so good and perfect for using discard. Thank you!
Diane says
Can this dough be made and long fermented in the fridge for 24 hours before baking? I assume with the egg and milk it’s better not to leave it on the countertop. Thanks!
Wendy M says
Is sour milk still viable? I have some I was going to bake a cake with, but this would be delightful instead.
Lisa Bass says
Yes, sour milk is still viable if it is raw milk!
Aria Inman says
Love it…thank you for the recipe. Aria
Jess Lambert says
Kiefer instead of buttermilk?
Lisa Bass says
That should work!
Cathy Strine says
I made the Irish Soda Bread very early this morning so we could eat a warm slice before heading to the beach to let our four dogs run while we walked our mile. Husband and I both loved it, and it will become a weekly special here at Roatan Strine Way. Thank you!
