Table Of Contents

What Is Irish Oat Bread?

Irish Oat Bread is a traditional type of bread that consists of oats, flour, salt, and buttermilk. It’s known for its tender texture and slightly sweet, nutty flavor. In my version, we’re omitting the flour by using oat flour and incorporating yogurt instead of buttermilk.

Just like many other kinds of bread, Irish Oat Bread pairs nicely with butter, jam, and honey. It’s a great oat bread recipe for beginner bakers, as it only uses a few ingredients and doesn’t require any fancy tools.

What’s The Difference Between Irish Oat Bread And Irish Soda Bread?

You may have heard of Irish Soda Bread and are wondering if it’s the same as Irish Oat Bread. Well, both Irish Oat Bread and Irish Soda Bread are traditional types of bread from Ireland, but they differ in ingredients and texture.

The oats in the Irish Oat Bread give it a chewier, denser texture with a slightly sweet and tangy flavor from the molasses and yogurt. On the other hand, Irish Soda Bread does not contain oats and – although dense – it has a crumblier texture with a more sour taste.

Moreover, Soda Bread traditionally includes a cross mark on the top of the loaf to help the bread cook more evenly and ward off evil spirits. Back in the 19th century, cutting a cross on the top of your bread was believed to let the devil out and bless the bread while baking.

Tools You Need To Make Irish Oat Bread:

Ingredients You Need To Make Irish Oat Bread:

  • Rolled oats: I recommend using old-fashioned (rolled) oats because they grind down very well into fine powder.
  • Baking soda: Baking soda is a chemical leavener that will make your bread rise.
  • Salt: Just a pinch will bring out the flavors of your ingredients.
  • Egg: Use a large, good-quality, room-temperature egg.
  • Whole milk yogurt: Yogurt makes your batter soft and fluffy without using oils. Do not use Greek yogurt because it will make your batter too thick.
  • Molasses: Adding molasses will add more moisture and texture to your delicious oat bread. Make Homemade Molasses from scratch!

How To Make Irish Oat Bread:

  1. Preheat the oven. Grease and line a loaf pan with parchment paper, and set aside.
  2. Place the oats into a food processor and process until ground into flour.
  3. Transfer oats into a bowl and toss with the baking soda and salt.
  4. In a separate bowl, whisk together the egg, yogurt, and molasses until well combined. Then, stir it into the oat mixture.
  5. Spread batter evenly into your prepared loaf pan and bake in the preheated oven until firm and a skewer inserted into the center comes out clean.
  6. Let cool in the pan before transferring to a wire cooling rack to cool completely.
  7. Slice and enjoy with some Irish Brandy Butter.

Can I Make Irish Oat Bread In Advance?

Yes, you can! If you want to serve freshly baked Irish Oat Bread, make the batter, spread it in your prepared loaf pan, and pop it in the refrigerator for up to a day until you want to bake it off.

How To Store Irish Oat Bread

If you have leftover Irish Oat Bread, store covered at room temperature for up to 4 days. For longer storage, freeze for up to 2 months.

What kind of oats should I use in Irish Oat Bread?

The best oats to use are old-fashioned rolled oats and quick-cooking oats. They’ll pulverize into fine powder for your flour. Unfortunately, steel-cut oats will not work for this recipe, as these oats are quite dense and will make the texture of your bread too dense.

What do I do if I don’t have molasses?

No worries! You can substitute the molasses with honey, but your Irish Oat Bread will turn out lighter in color.

Is Irish Oat Bread gluten-free?

The good news is Irish Oat Bread is gluten-free (with certified gluten-free oats)! I don’t use all-purpose flour in this bread like traditional recipes, but it tastes just as good or even better. Take a look at my Gluten-Free Flours Guide if you want to substitute the oats and make a different kind of bread.

Is Irish Oat Bread vegan?

Though my Irish Oat Bread recipe contains eggs and yogurt, you can go ahead and substitute them with different ingredients. For the eggs, check out my Egg Substitutes post for more information; and for the whole milk plain yogurt, I recommend replacing it with buttermilk (make it vegan) , sour cream,  cottage cheese, or ricotta

What should I do if I don’t have a food processor?

If you don’t have a food processor, the next best option will be a blender. It may not be as smooth of a flour texture, but it will get close enough.

Gemma’s Pro Chef Tips:

  • Use rolled oats (old-fashioned oats), but steel-cut oats will not work.
  • This recipe calls for Plain yogurt, not Greek. Greek is too thick for this recipe.
  • You can use my Homemade Molasses if you don’t have it to hand.
  • If you don’t have molasses, you can use honey instead. The loaf will be lighter in color.
  • This bread is flourless, so it’s perfect if you are gluten-free.
  • You can sprinkle 1 cup (5 oz/142 g) of chopped dried fruit, nuts, or seeds into this loaf just before baking. I recommend raisins and caraway seeds.
  • This bread dough is a little heavy like Soda Bread and won’t rise very much but it will be very soft.
  • Try serving this with one of my Compound Butter recipes!

I’m typically not a bread maker, but this is one of the easiest and most delicious bread I’ve made from scratch. Hard to believe it’s gluten free. I added almonds, walnuts, and cranberries for a little something extra. I’ll definitely make this again (and again, and again). Scrumptious.

Hi Gemma, I didn’t have much luck with this one, like many of your quick breads that I’ve tried, it comes out wet or soggy in the middle. I left this one in the oven for 1.5hr and it was still wet. I do think the issue is my old and basic oven (soon to be replaced) with only fan setting. I hope to try all of these recipes again but is there anything you could suggest in the meantime, higher temp, longer cook, less liquid? Thank you as always! Although it was soggy, it still tasted very good so… Read more »

Can I use honey as a substitute for molasses.

This recipe turned out to be really delicious! The bread is soft and can easily substitute for your regular bread. I wonder if you have any information about the GI and the nutritional values of this particular recipe? I would recommend it to my mum but she’s supposed to have a low GI diet, so I was wondering if she could have this bread. Thanks for the recipe!
