This old fashioned soda bread is the real deal: a crusty, golden loaf with a soft, tender crumb that comes together in about 10 minutes with no yeast, no kneading, and no waiting for a rise. It gets its lift from the classic reaction between baking soda and acidic buttermilk, which gives the bread its signature tangy flavor and dense-yet-tender texture. It’s the perfect quick bread for breakfast, soup, or slathered with butter and jam.
Ingredients
- 4 cups (500 g) all-purpose flour, plus more for dusting
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 tablespoon sugar (optional, for a slightly sweeter crust)
- 1¾ cups (420 ml) buttermilk, cold (see Tips for substitution)
Instructions
- Preheat your oven to 425°F (220°C). Place a rack in the middle position. Line a baking sheet with parchment paper or lightly flour it.
- In a large mixing bowl, whisk together the flour, baking soda, salt, and sugar (if using) until well combined.
- Make a well in the center of the dry ingredients and pour in the cold buttermilk.
- Using a wooden spoon or your hands, mix until a shaggy dough forms. The dough should be soft but not sticky; if it’s too dry, add a splash more buttermilk. If it’s too sticky, add a little more flour.
- Turn the dough out onto a lightly floured surface and gently knead it 5–6 times, just until it comes together into a round ball. Do not over-knead, or the bread will be tough.
- Shape the dough into a round loaf about 7–8 inches (18–20 cm) in diameter and place it on the prepared baking sheet.
- Using a sharp knife, cut a deep cross (an X) into the top of the loaf, about ½ inch (1.25 cm) deep. This helps the bread expand and bake through the center.
- Bake for 35–40 minutes, until the crust is deep golden brown and the loaf sounds hollow when tapped on the bottom. If you have an instant-read thermometer, the internal temperature should read about 200°F (93°C).
- Transfer to a wire rack and let cool for at least 15 minutes before slicing. Serve warm or at room temperature.
Tips
- Buttermilk substitute: If you don’t have buttermilk, add 1 tablespoon of lemon juice or white vinegar to 1¾ cups of milk and let it sit for 5 minutes before using. It won’t be quite as thick, but it will still react with the baking soda.
- Don’t overmix: Soda bread is meant to be rustic. Overmixing develops gluten and makes the bread tough and rubbery. Mix just until the flour is incorporated, then stop.
- Use cold buttermilk: Cold buttermilk helps keep the dough from getting too soft and sticky, which makes it easier to shape and gives a better crumb.
- Check for doneness: If the top is browning too quickly, tent loosely with foil for the last 10 minutes. The bread is done when a toothpick inserted in the center comes out clean (a few moist crumbs are fine).
Serving Suggestions
Slice the soda bread thick and serve it warm with butter and a drizzle of honey or your favorite jam. It’s also fantastic alongside a bowl of hearty soup, like beef stew or potato leek soup, or with smoked salmon and cream cheese for a brunch spread. For a classic Irish breakfast, toast a slice and top with a fried egg.
Variations
- Sweet soda bread: Add ⅓ cup (65 g) of raisins or currants and 2 tablespoons of sugar to the dry ingredients. You can also add 1 teaspoon of caraway seeds for a traditional Irish flavor.
- Whole wheat soda bread: Replace 1 cup (125 g) of the all-purpose flour with whole wheat flour. You may need an extra tablespoon or two of buttermilk, as whole wheat absorbs more liquid.
- Cheese and herb: Fold in ¾ cup (85 g) of shredded sharp cheddar and 2 tablespoons of chopped fresh chives or rosemary before adding the buttermilk.
- Skillet version: Instead of a baking sheet, bake the dough in a well-greased 9-inch cast-iron skillet. This gives a thicker, rounder loaf with a softer side crust.
Storage and Reheating
Store leftover soda bread in an airtight container or wrapped tightly in plastic wrap at room temperature for up to 3 days. It will dry out quickly, so it’s best eaten within a day or two. To reheat, wrap slices in foil and warm in a 350°F (175°C) oven for 5–8 minutes, or toast individual slices. Soda bread also freezes well: wrap the whole loaf or slices in plastic wrap and then foil, and freeze for up to 3 months. Thaw at room temperature and reheat as above.
Frequently Asked Questions
Why is my soda bread dense and heavy? This is often caused by overmixing the dough, which develops too much gluten. It can also happen if the baking soda is old and no longer active. Make sure your baking soda is fresh and mix the dough just until it comes together.
Can I use regular milk instead of buttermilk? No, buttermilk is essential because its acidity reacts with the baking soda to create leavening. If you don’t have buttermilk, use the milk + lemon juice/vinegar substitute mentioned in the Tips. Regular milk alone won’t give the same rise or flavor.
Why do I cut a cross in the top? The cross serves two purposes: it allows the heat to penetrate the center of the thick loaf, ensuring it bakes through, and it’s traditional in Irish folklore to let the fairies out. It also creates a nice place to break the bread into quarters.
Can I make this gluten-free? You can try using a 1:1 gluten-free all-purpose flour blend, but the texture will be different and may be more crumbly. Add 1 teaspoon of xanthan gum if your blend doesn’t include it. You may also need to add a little more buttermilk.
How do I know when it’s done? The loaf should be deep golden brown and sound hollow when tapped on the bottom. An instant-read thermometer should read about 200°F (93°C) in the center. If the top is browning too fast, cover with foil.
Why is my crust too dark? Ovens vary, and a dark or nonstick baking sheet can cause faster browning. Try placing the loaf on a light-colored sheet or lower the oven temperature by 25°F (15°C). You can also tent with foil halfway through baking.
