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.

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

How to make Seeded Whole Grain Soda Bread
Back to contentsMix 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.
