01 - Preheat the oven to 425°F. Line a baking sheet with parchment paper.
02 - In a large bowl, whisk together flour, baking powder, baking soda, salt, pepper, and dried thyme.
03 - Add the cold, cubed butter to the dry ingredients. Using a pastry cutter or fingertips, work the butter into the mixture until it resembles coarse crumbs.
04 - Stir in shredded cheddar cheese and optional chopped herbs evenly.
05 - Pour in cold buttermilk and gently mix until the dough just comes together. Avoid overmixing to prevent toughness.
06 - Turn the dough onto a lightly floured surface. Pat into a 1-inch thick rectangle.
07 - Using a 2½-inch round cutter, cut biscuits from dough, reassembling scraps as needed. Place biscuits 2 inches apart on the prepared baking sheet.
08 - Bake for 15 to 18 minutes until golden brown. Allow to cool slightly before serving.
