Perhaps the unsung hero of all quick breads, soda bread is a unique free-form loaf that contains no baking powder or yeast to make it rise. Interestingly enough, it's a chemical reaction that makes the dough rise. Since there's no yeast involved, this can be ready to eat really quickly!

Ingredients

Wondering what ingredients you need to make a loaf of oregano onion soda bread? Let's look at the most important ones!
- Flour: For the best rise and texture, it's recommended to use bread flour. You can also use a 50-50 blend of bread flour and all-purpose.
- Buttermilk: You can use store-bought buttermilk or make your own by mixing 1 tablespoon of white vinegar or lemon juice with 1 cup of milk and letting it stand for 10 minutes.
- Baking Soda: This reacts with the buttermilk to make the bread rise. Make sure your baking soda is no older than 3 months, or it will be less effective in your baking.
- Oregano & Onion: Use chopped fresh oregano or a couple teaspoons of dried oregano. Diced white or yellow onion works well in this recipe.
How to Make
Gather the ingredients (flour, buttermilk, chopped sweet onion, baking soda, salt, pepper, butter, and chopped fresh oregano.)
Whisk together the dry ingredients in a medium mixing bowl.

Melt the butter in a small skillet over medium-high heat until bubbly, then add the onions and sauté until golden brown.

Add the sautéed onions and chopped oregano to the dry ingredients, then mix in enough buttermilk to make a sticky dough.

Turn out the dough onto a lightly floured surface and knead gently a few times, then shape into a ball.

Place the loaf on a baking stone or parchment-lined cookie sheet. Cut a deep X into the loaf, cutting almost all the way through the dough. This helps it cook properly.

Bake at 400 F for 45-55 minutes, until the loaf is well browned on the top and base and has an internal temperature of 200 F on a meat thermometer. Let it cool completely on a wire rack before serving to allow it to finish cooking.
Recipe FAQs
It has a similar nutritional profile to traditional yeast breads. You can make it healthier by substituting whole wheat flour for the white flour. This recipe is actually quite filling, so you won't need a large piece.
It gets its name from the baking soda that is used to make it rise.
Yes, they are the same thing--just different names. Americans and Canadians use the term baking soda, while Brits, Australians, and New Zealanders use the term bicarbonate of soda (or "bicarb" for short).
No, they are not the same. Sourdough is made from natural yeast, while soda bread contains no yeast--just baking soda--to make it rise.
Store
- Eat it as soon as it's cooled for the best flavor. Seal it tightly in a zip-top plastic bag at room temperature. Do not refrigerate; it will make it go stale more quickly.
- Freezing: For best freshness, freeze the bread as soon as possible. Make sure to seal it tightly in a zip-top plastic bag, pressing out the extra air. Freeze for up to 1 month.
Serve
- Spread with salted butter.
- Dip into a bowl of hearty soup.
- Place a piece of cheese on top of your slice.
- Serve it with fresh fruit and veggies.
- Make it into a sandwich.
- Toast leftovers to serve with soup or use it in a sandwich.
Expert Tips
- Use bread flour instead of all-purpose flour. It has a higher protein content than all-purpose, which creates more gluten in the dough. Gluten gives the dough strength, allowing it to rise higher as it bakes and giving it a more pleasant texture.
- Be careful not to overwork the dough, or it will be tough. The more you knead and handle the dough, the more you strengthen the gluten strands. You need some gluten to create a good loaf, but not too much. Just gently knead a couple times, and you'll be fine.
- Bake until it's well browned on the top and base and has an internal temperature of 200 F. Pulling out the loaf too soon will make it doughy and undercooked.
- Let it cool completely before serving. It needs time to release the trapped steam and finish cooking all the way through. Cutting in too soon will make the dough dense, stodgy, and doughy.

Recipe

Oregano Onion Soda Bread
Ingredients
- 4 ⅛ cups bread flour, 500g
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 cup sweet onion, chopped
- 3 tablespoons fresh oregano leaves, chopped
- Freshly ground black pepper, to taste
- 1 ⅔ - 2 cups buttermilk
Instructions
- Preheat the oven to 400 F.
- Rinse the fresh oregano and pat the stems dry. Remove the leaves by running your fingers down the stem from the top to the bottom, then finely chop the leaves.
- Chop the onion, then melt 2 tablespoons of butter in a small saucepan over medium-high heat. Add the onions and cook until golden brown, stirring frequently.
- Whisk together the flour, salt, and baking soda in a large bowl, then stir in the oregano and onion.
- Make a well in the center of the mixture. Pour half of the buttermilk into the well and mix with your hand until the dough starts to come together.
- Gradually add more buttermilk until a sticky dough is formed and no flour remains in the bottom of the bowl. If you have extra buttermilk, save it for another bake. Don't over mix, as this will build up the gluten structure in the dough and make a tough, doughy loaf.
- Working quickly, form the dough into a ball on a lightly floured surface, handling the dough as little as possible. Pat the top down gently and place on a large baking stone or parchment-lined cookie sheet.
- Score the dough in an X shape with a large, sharp knife. Cut almost all the way through, but make sure to leave the four quarters (called farls) attached. The scoring allows the heat to penetrate the dough much better.
- Immediately bake at 400 F for 45-55 minutes, until the base and top are well browned and the loaf has risen completely. The loaf's internal temperature should be about 200 F.
- Leave to cool completely on a wire rack before serving. The bread finishes cooking through the middle as it cools. Serve with butter.
Notes
- Be careful not to overwork the dough, or it will be tough.
- Bake until it's well browned and has an internal temperature of 200 F.
- Let it cool completely before serving; otherwise, the bread will be undercooked and doughy.
- Eat it the same day for the best taste, or freeze in a zip-top bag for up to 1 month.
- Toast leftovers to enjoy with soup or in a sandwich.

This oregano soda bread is soft and has a nice crust. I like the oregano and onions. They are rather unusual to put in a bread, but it is quite nice.
Emma
I like the flavor combination of oregano and onions, too!
