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