  1. Bake for 30-35 minutes or until golden brown on top and cooked through.

  2. Pierce with a skewer to make sure in case it’s still gooey inside, if so let it bake for another 5 minutes then check again”

For those who like to experiment with flavors and textures, this seeded sourdough soda bread is versatile enough to accommodate substitutions and variations. Here are some ideas to inspire you:

– Flour: While the recipe calls for a combination of unbleached all-purpose flour and whole wheat flour, you can play around with other types of flours, such as rye, spelt, or buckwheat. Keep in mind that using too much whole grain flour may result in a denser loaf, but it will also add more fiber and nutrients.

– Seeds and Grains: The recipe suggests using a mix of seeds and grains of your choice, such as sunflower seeds, flax seeds, sesame seeds, oats, or cornmeal. You can also try adding nuts, dried fruit, or cheese for added crunch and flavor.

– Sourdough Starter: If you don’t have any sourdough starter on hand, you can make your own using King Arthur Flour’s step-by-step guide. Alternatively, you can use active dry yeast or instant yeast instead of the starter. Keep in mind that the rising time may be different depending on the type of yeast you use.

– Gluten-Free: For those who avoid gluten, you can try using a gluten-free flour blend that contains xanthan gum to help with the texture. King Arthur Flour’s Gluten-Free Measure for Measure Flour is a great option that works well in most bread recipes.

– Irish Soda Bread: If you prefer the classic Irish soda bread taste, you can omit the sourdough starter and use 4 teaspoons of baking soda instead. This will result in a softer and slightly sweeter loaf that pairs well with butter and jam.

Whether you stick to the original recipe or customize it to your liking, this seeded sourdough soda bread is a delicious and healthy addition to your baking repertoire. Experiment away!

One of the best things about this seeded sourdough soda bread is that it can be made ahead of time and stored for later use. Once baked, allow your bread to cool completely before wrapping it tightly in plastic wrap or aluminum foil. It will stay fresh for up to 3 days when stored at room temperature.

To reheat a slice of bread, preheat your oven to 350°F and place the slice on a baking sheet. Bake for 5-7 minutes or microwave it for 10-15 seconds. Alternatively, you can toast your bread in a toaster for a crunchy texture.

If you want to make your bread dough ahead of time, you can also store it in the refrigerator overnight. Simply cover the bowl with plastic wrap or a towel and put it in the fridge. When ready to bake, take the dough out of the refrigerator and allow it to come back to room temperature before shaping and baking.

It is also possible to freeze your seeded sourdough soda bread dough. After shaping your loaf, wrap it tightly in plastic wrap or aluminum foil and store it in the freezer for up to one month. When ready to use, simply thaw out your dough overnight in the refrigerator before continuing with baking instructions.

When it comes to baking bread, achieving the perfect consistency and taste can be a bit tricky. Here are some tips that will help ensure your seeded sourdough soda bread turns out just right.

The first tip is to make sure you accurately measure your ingredients. Even small variations in the quantities of the ingredients can drastically affect the final product. To ensure accuracy, use a kitchen scale to weigh your ingredients instead of measuring them with cups and tablespoons.

Another important tip is to let the bread dough rise properly. This will have a significant impact on the texture and flavor of the final loaf. Make sure to let the bread rise for enough time, as this will allow it to develop properly before baking. The amount of time required for the bread to rise will depend on a number of factors – such as room temperature, humidity, and altitude – so keep an eye on it and adjust accordingly.

A great way to add some extra flavor and texture is to mix in some seeds or grains of your choice. Sunflower seeds are a popular addition in seeded sourdough soda bread, but you can try using other seeds as well. Whole wheat and mixed grain sourdoughs are also worth exploring.

One key element in achieving a great sourdough flavor is using sourdough starter that has been maintained properly. Ensure your starter is at its peak strength by feeding it regularly with equal parts flour and water.

If you’re struggling with getting enough rise out of your bread dough, try adding some gluten-free flours such as emmer flour or xanthan gum which can help bring strength back into the gluten-free recipe while enhancing flavor.

Finally, resist the temptation to cut into your bread while it’s still warm. Allowing the bread to cool completely before slicing will make for a cleaner cut and prevent squishing the warm center from rushing out or drying out too quickly. And don’t forget – fresh homemade baked bread is always best when paired with some butter or spread of your choice!


Now that we’ve gone through all the steps and shared tips about making the Seeded Sourdough Soda Bread, it’s time to dive into some of the most frequently asked questions about this recipe. These FAQs will guide you through common queries to make sure you produce a consistent result each time – no matter how many times you bake it!

What is the difference between sourdough bread and soda bread?

When it comes to making bread, the type of leavening agent used can make all the difference. Sourdough bread relies on yeast and bacteria fermentation to release gasses and create its rise, while soda bread uses baking soda and acids in the dough to produce its signature airiness. These varying methods have a big impact on the flavor and texture of each type of bread.

What is the secret to good sourdough bread?

Let’s get that starter rip-roaring and ready to go. Activate it with some fresh feeding and let’s see it spring into action. It’s time to break out of our white flour bubble and explore the world of whole grains. Be mindful of your dough’s hydration – too much or too little water can greatly impact your final product. Don’t rush to the mixing stage; give your dough and flour some quality time together during the autolyse. Slow and steady wins the race during bulk fermentation, so be patient and let the yeast work its magic. Time to proof up that dough before we throw it into the oven. And don’t forget to properly prepare your baking surface for optimal results.

Is soda bread healthier than sourdough?

If you’re looking for a nutritious and easy-to-digest bread, then sourdough is the way to go. Not only does it have a lower glycemic index, but it also contains less gluten than other types of bread. This makes it a great option for people who are sensitive to gluten but still want to enjoy artisan or homemade bread. In this article, we’ll explore why sourdough is such a healthy and delicious choice.

What does apple cider vinegar do in sourdough bread?

Apple Cider Vinegar is a small but mighty ingredient in our recipe. Despite not having any impact on taste, it’s a natural way to prolong the freshness of our bread on its journey to you. Not only that, but it is also incredibly beneficial for your health. So don’t be fooled by the small amount used, as its benefits are huge! This is just one small way we prioritize both taste and quality for our customers.

Bottom Line

In conclusion, this seeded sourdough soda bread recipe is a must-try for any bread lover. With its crusty exterior and hearty, wholesome interior, it’s sure to be a crowd-pleaser at any meal. The combination of whole wheat and all-purpose flour creates a balanced and complex flavor profile that will satisfy any palette.

Moreover, the versatility of this recipe allows for countless variations and substitutions to make it your own. From adding in different seeds and grains to using sourdough discard or even gluten-free flour with xanthan gum, the possibilities are endless.

But whatever way you choose to make this bread, one thing is certain: with the high-quality ingredients from King Arthur Flour and a little bit of patience, you’ll have a delicious loaf of bread that will quickly become a family favorite.

So don’t be intimidated by the thought of making your own bread – give this recipe a go and enjoy the satisfaction that comes with making something from scratch. Trust me, there’s nothing quite like the smell of fresh-baked bread filling your home.

Seeded Sourdough Soda Bread from KAF Recipe

Want to make Irish Soda Bread for St. Patrick's Day but wanted to use up my Sourdough Starter, found this at King Aurthur Flour on line. It states: Soda bread is a staple around St. Patrick's Day, and this is a tried and true soda bread recipe, with a variation with a just a touch of background sourdough note. Have to admit while I posted as listed I changed it around so not truly an Irish bread but a great sandwich bread - changes; added 1 teaspoon of bread yeast, instead of 3 tablespoons of honey used half honey & half molasses, dumped all in ABM on dough cycle, then let rise for 2 hours prior to baking.

Keyword: < 60 Mins, Breads, European, St. Patrick's Day
Prep Time: 15 minutes
Cook Time: 30 minutes
Servings: 2 Loaves
Calories: 384.1kcal


  • 2 1/2 cups whole wheat flour
  • 1 1/4 cups unbleached all-purpose flour
  • 1/2 cup seeds, and grains of your choice
  • 1 teaspoon baking soda
  • 3/4 teaspoon salt
  • 1 cup sourdough starter (fed or unfed)
  • 1/4 cup butter, melted
  • 3 tablespoons honey
  • 3/4 cup milk


  • Preheat the oven to 400°F Lightly grease a baking sheet, or line it with parchment.
  • In a medium-sized mixing bowl, whisk together the flours, Harvest Grains Blend, baking soda, and salt.
  • In a separate bowl (or in a measuring cup), whisk together the starter, butter, honey, and milk. Pour this mixture into the dry ingredients and stir to combine. The dough will be stiff; if it's too crumbly to squeeze together, add another tablespoon or two of milk.
  • Knead the dough a couple of times to make sure it's holding together, divide it in half, and shape each half into a ball. Flatten the balls slightly, and place them on the prepared baking sheet. Use a sharp knife to cut a ½"-deep cross, extending all the way to the edges, atop each loaf.
  • Bake the loaves for 30 to 40 minutes, until they're golden brown and a cake tester or toothpick inserted into the center comes out clean. Remove the loaves from the oven, and brush their tops with melted butter, if desired.
  • NOTE: you may freeze some of the dough for later. Shape and allow to freeze to the point where you are able to wrap or place into a freezer zip lock bag. Using a second bag would be even better. Allow to defrost in the frig overnight before baking. If you would like to freeze after baking, allow to defrost at room temperature and warm in a preheated oven for 5 to 10 minutes to freshen up the crust and interior.
