A Modern Twist on Irish Soda Bread: Gluten-Free and Full of Flavor
Irish soda bread is a classic. It’s simple, comforting, and fast to make. But traditional recipes often rely on wheat flour. Today, we’re making a gluten-free, oat-forward version that still rises nicely and tastes amazing. It’s soft inside, with a gentle crust outside. The combination of oat, millet, and sweet rice flours gives it structure, while potato starch and xanthan gum keep it tender. Adding whipped potato protein gives lift and fluffiness, creating a taller, lighter loaf than typical gluten-free soda breads. This bread is ideal for breakfast, tea, or a quick snack. It pairs well with jam, nut butter, or just butter.
If you’ve struggled with flat soda bread in the past, this recipe has tweaks that help. Preheating the oven properly, scoring lightly, and handling the dough gently are key. The non-dairy milk and apple cider vinegar act as your acid, activating the baking soda. The small touch of sugar balances the flavor without making it sweet. One important tip: bake until the internal temperature reaches 190°F (88°C) for a fully cooked, tender center. Overall, it’s a forgiving bread that even beginners can enjoy.
The History of Soda Bread and Its Modern Variations
Soda bread has roots in Ireland, dating back to the early 1800s. Before commercial yeast was widely available, people used bicarbonate of soda as a leavening agent. It reacts quickly with acids in the dough, creating carbon dioxide that helps the bread rise. During the Great Famine, soda bread became a staple because it was fast, easy, and required few ingredients. (SodaBread.info)
Over time, bakers started experimenting. Some added sugar, fruit, or seeds. Others combined flours, making it more nutritious or suitable for different dietary needs. Today, gluten-free and alternative-flour versions are increasingly popular. (ICE.edu blog)
This version, using oat, millet, and sweet rice flours with potato starch, is part of that modern evolution. It honors the simplicity of traditional soda bread while catering to those with dietary restrictions. The addition of whipped potato protein is essential, giving the bread structure and lift that traditional wheat gluten would provide. Baking until the internal temperature reaches 190°F ensures a perfectly cooked loaf without a gummy center.

Ingredients
Dry Ingredients:
- Oat flour
- Millet flour
- Sweet rice flour
- Potato starch
- Xanthan gum
- Baking soda
- Cream of tartar (optional)
- Salt
- Sugar (optional)
Wet Ingredients:
- Non-dairy milk
- Apple cider vinegar
- Neutral oil
- Potato protein (hydrated and whipped)
Optional: Add-ins like seeds, dried fruit, or herbs for extra flavor.
This combination is carefully chosen to produce a tender, structured, and fluffy loaf. The potato protein is non-negotiable for achieving lift in gluten-free soda bread.
Step-by-Step Instructions for the Perfect Loaf
Preheat the oven to 375°F (190°C). Grease your pan or line with parchment. Proper preheating helps the bread rise well.
Mix non-dairy milk with apple cider vinegar. Let it sit for 5 minutes. This creates a buttermilk-like acid that activates the baking soda.
In a stand mixer or large bowl, combine all dry ingredients: oat flour, millet flour, sweet rice flour, potato starch, xanthan gum, baking soda, cream of tartar (if using), salt, and sugar.
Add the milk + vinegar mixture and oil to the dry ingredients. Mix until a thick, sticky dough forms. Don’t overmix; stop as soon as combined.
Gently fold in the whipped potato protein by hand. This is crucial. It gives the bread lift and fluffiness that no other ingredient can replace.


Shape the dough in your prepared pan. Score lightly on top with a sharp knife or bench scraper. Remember, it’s just a mark—too deep can flatten the bread.

Bake for 45–50 minutes, or until golden. Check the internal temperature: it should read 190°F (88°C) for a fully cooked, tender center. For a crisper crust, remove the bread from the pan for the last 10 minutes.
Cool for 15 minutes before slicing. This lets the structure set and makes cutting easier.
FAQ About This Gluten-Free Soda Bread
Why do I need potato protein?
Potato protein is essential. It provides lift and fluffiness that gluten-free flours alone cannot. Without it, the bread will be dense and flat.
Can I make this sweeter?
Yes, add honey, maple syrup, or extra sugar. Too much sugar may slightly reduce rise.
Why didn’t my bread rise?
Common causes: overmixing, scoring too deeply, weak acid reaction, or not folding in the whipped potato protein properly.
Can I use other flours?
Yes, but keep a structured flour (like oat) with a sticky starch (like sweet rice or potato) for best texture.
How do I store it?
Cool completely. Wrap in a towel or parchment at room temperature. For longer storage, slice and freeze.
How do I know when it’s fully baked?
Check the internal temperature: 190°F (88°C) is ideal. Also, a toothpick inserted should come out clean.

Closing Thoughts
This oat-millet-sweet-rice soda bread shows how traditional recipes can evolve. Simple ingredients, a little lift from whipped potato protein, and gentle handling produce a loaf that is soft, tall, and flavorful. Checking for an internal temperature of 190°F ensures a tender, fully cooked center.
Make it on a weekend morning. Enjoy the aroma as it bakes. Slice warm with jam, butter, or your favorite spread. Experiment with seeds, herbs, or dried fruit. Each loaf connects past and present while keeping your kitchen simple and joyful.
