01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease with butter.
02 - In a large mixing bowl, whisk together the flour, sugar, baking soda, and salt until well blended.
03 - Add the grated cheddar, chives, parsley, and thyme to the dry mixture. Stir until evenly distributed throughout the flour.
04 - In a separate bowl, whisk together the cold buttermilk, melted butter, and beaten egg until combined.
05 - Pour the wet ingredients into the dry mixture. Using a wooden spoon, mix just until a shaggy dough forms. Do not overmix.
06 - Turn the dough onto a lightly floured surface. Gently knead 4 to 5 times to bring it together, then shape into a round loaf about 7 inches in diameter.
07 - Transfer the loaf to the prepared baking sheet. Using a sharp knife, cut a deep X across the top of the dough.
08 - Bake for 35 to 40 minutes until the crust is deeply golden brown and a skewer inserted into the center comes out clean.
09 - Let the bread cool on a wire rack for at least 20 minutes before slicing to allow the crumb to set.
