Seeded Whole Grain Soda Bread

This seeded wholemeal soda bread is a hearty, nutrient-dense loaf that celebrates the deep, nutty flavours of ancient grains. By soaking millet, quinoa and amaranth in tangy buttermilk, the bread develops a complex texture and a moist, satisfying crumb that sets it apart from standard quick breads. It is a wonderful vegetarian option for those who want the rustic appeal of a traditional loaf without the need for yeast or lengthy proving times.

Perfect for a weekend brunch or as a wholesome accompaniment to a seasonal vegetable soup, this homemade bread is remarkably simple to prepare. The addition of flaxseeds and sunflower seeds provides a delightful crunch and a wealth of healthy fats, making it a brilliant choice for a nutritious family lunch. Enjoy it toasted with a generous spread of salted butter or served alongside a sharp cheddar cheese.

Ingredients for Seeded Whole Grain Soda Bread

  • 60ml millet

  • 60ml quinoa

  • 2 tablespoons amaranth

  • 90g old-fashioned oats, plus more for topping

  • 550ml buttermilk, divided, plus more for brushing

  • 1 tablespoon vegetable oil, plus more for pan

  • 375g wholemeal flour

  • 130g plain flour

  • 2 tablespoons flaxseed

  • 1 tablespoon kosher salt

  • 2 teaspoons bicarbonate of soda

  • 35g sunflower seeds, plus more for topping

  • 4 tablespoons unsalted butter, cut into pieces

  • 45ml brown rice syrup or mild-flavoured (light) molasses

Mix millet, quinoa, amaranth, 240ml oats, 240ml buttermilk, and 120ml water in a small bowl. Cover and let sit 8–12 hours. (Alternatively, bring ingredients to a simmer in a small saucepan over low heat. Remove from heat and let sit until mixture is thick like porridge, about 2 hours.)

Preheat oven to 177°C. Lightly oil an 8"-diameter cast-iron skillet or cake pan. Whisk wholemeal flour, plain flour, flaxseed, salt, bicarbonate of soda, and 60g sunflower seeds in a large bowl. Work in butter with your fingers until largest pieces are pea-size. Make a well in the centre and add brown rice syrup, oat mixture, remaining 300ml buttermilk, and remaining 1 tablespoon oil. Mix with a wooden spoon until dough is smooth, homogenous, and still slightly sticky.

Form dough into a ball and place in prepared pan. Brush with buttermilk; top with more oats and sunflower seeds. Cut a large X into the top and bake until golden brown and an instant-read thermometer inserted into the centre of loaf registers 88°C, 55–70 minutes. Let cool in pan.

Bread can be baked 2 days ahead. Store tightly wrapped at room temperature.
