You'll never buy a loaf again after making this. Four ingredients, no yeast, no waiting — just a golden, crackling crust with a tender, tangy crumb that's ready in 40 minutes flat. This is the soda bread recipe that actually works every single time.
Preheat your oven to 425°F (220°C) and lightly flour a cast iron skillet or baking sheet. High initial heat helps set the crust for that classic crackle.
In a large bowl, whisk together flour, baking soda, and salt. Distribute the baking soda evenly—this ensures the bread rises uniformly.
Add cold cubed butter to the flour mixture. Rub the butter in quickly using your fingertips until the largest pieces are pea-sized—keeping the butter cold creates a flakier, more tender crumb.
Make a well in the center, add all the buttermilk, and mix gently with a fork just until a rough dough forms. Do not over-mix—excess mixing toughens the loaf by developing too much gluten.
Turn dough onto a floured surface and gently shape it into a 7-inch round. Transfer to the skillet, score a deep 'X' across the top (about ¾ inch deep)—this helps the center cook through evenly and gives the loaf its traditional look.
Bake for 35–40 minutes, until deeply golden and the bottom sounds hollow when tapped. For best texture, cool at least 10 minutes before slicing—the crumb sets as it cools.
