In a large mixing bowl, combine the sourdough starter, warm milk, sugar, olive oil or melted butter, and salt.
02 -
Gradually incorporate the flour into the wet mixture, stirring and kneading until a soft, smooth dough develops.
03 -
Cover the dough and allow it to rise at room temperature for 4–6 hours until doubled in size, or refrigerate overnight for a slower fermentation.
04 -
Roll the dough out on a lightly floured surface into a rectangle approximately 25x40 cm. Evenly spread softened butter over the dough, then scatter the shredded cheese, garlic powder, chopped herbs, salt, and pepper across the surface.
05 -
Tightly roll the dough from the long side to form a log, then slice into rounds approximately 2.5–4 cm thick. Arrange the slices, cut side up, in a greased or parchment-lined baking dish.
06 -
Loosely cover and let the rolls rise for 1–2 hours at room temperature, or until visibly puffy.
07 -
Preheat oven to 190°C. Brush the tops of the rolls with the beaten egg for shine, if desired. Bake for 20–25 minutes, or until golden brown and bubbling.
08 -
Once out of the oven, garnish the warm rolls with extra fresh herbs or parmesan if desired. Serve warm or at room temperature.
