Preheat oven to 375˚F.
Place flour, sugar, baking soda, and salt into a large mixing bowl and whisk together.
Cut in butter with a pastry knife or using your fingers until the butter is well blended into the dough and forms a coarse texture.
Fold in orange juice, zest and dried blueberries until just combined.
Stir in buttermilk until a rough dough forms. Dump dough onto a clean surface and knead a few times until the mixture fully comes together and no dry spots remain.
Form dough into a large, round loaf and score and “X” onto the top, with a knife.
Transfer onto a parchment lined baking sheet and bake for 45 to 50 minutes or until a toothpick comes out clean when inserted into the center of the loaf.
Allow soda bread to cool for about 1 hour before slicing and serving.
