Ingredients
1 tablespoon olive oil1 medium onion, chopped5 garlic cloves, minced4 cups all-purpose flour1 teaspoon salt1 teaspoon baking soda1/4 cup cold butter, cubed1 large egg, room temperature1-1/2 cups buttermilk
Preparation
Preheat oven to 425°. In a small skillet, heat oil over medium-high heat. Add onion; cook and stir until light golden brown, 3-5 minutes. Add garlic; cook and stir 30 seconds longer. Cool.
In a large bowl, whisk flour, salt and baking soda. Cut in butter until mixture resembles coarse crumbs. Stir in cooled onion mixture; make a well in center. In a small bowl, whisk egg and buttermilk; pour into well. Using a wooden spoon, mix dough until too stiff to stir. Turn onto a lightly floured surface; knead gently 10 times. Shape into a round loaf.
Transfer to a large greased cast-iron skillet or baking sheet. Using a sharp knife, cut a shallow “X” on the top of loaf. Bake until golden brown, 35-40 minutes.
Remove from pan to a wire rack; serve warm.
