Recipe Information
Ingredients
- 6 tablespoons Unsalted butter
- 1 medium Yellow onion
- 2 cups All-purpose flour
- 1 tablespoon Baking powder
- 0.25 teaspoons Baking soda
- 0.5 teaspoons Salt
- 1 teaspoons Granulated sugar
- 6 tablespoons Cold unsalted butter, cubed
- 0.5 cups Sourdough starter discard
- 0.5 cups Cold buttermilk
Instructions
Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.
Peel and thinly slice the yellow onion. In a skillet, melt 6 tablespoons of unsalted butter over medium heat. Add the sliced onions and cook, stirring occasionally, for 20-25 minutes or until the onions are deep golden brown and caramelized. Remove from heat and let cool.
In a large mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, and granulated sugar.
Add the cubed cold unsalted butter to the dry ingredients. Using a pastry cutter or your fingertips, work the butter into the flour mixture until the texture resembles coarse crumbs.
Stir in the caramelized onions, ensuring they are evenly distributed throughout the mixture.
In a separate small bowl, whisk together the sourdough starter discard and cold buttermilk. Pour this mixture into the dry ingredients, stirring just until combined. Do not overmix.
Turn the dough out onto a lightly floured surface and pat it into a rectangle about 1 inch thick. Fold the dough in half, then pat it out again. Repeat this process twice more to create flaky layers.
Cut the dough into rounds using a biscuit cutter (about 2.5 inches in diameter), or cut into squares with a knife. Gather any scraps and repeat until all the dough is used.
Place the biscuits on the prepared baking sheet, spacing them about 1 inch apart.
Bake in the preheated oven for 12-15 minutes, or until the biscuits are golden brown on top.
Remove from the oven and let cool slightly on the baking sheet before serving. Enjoy warm or at room temperature!
