Begin by combining 2 cups (250g) bread flour, 1½ teaspoons fast-acting dried yeast, ½ teaspoon salt, 1½ tablespoons olive oil, and ⅔ cup (175ml) slightly warm water in a mixing bowl.
Stir these ingredients together until a soft, wet dough forms, then transfer to a lightly floured surface and knead for 5–8 minutes until the dough becomes smooth and shiny.
Once kneaded, place the dough in an oiled bowl, cover tightly with plastic wrap, and allow it to rise for approximately 1½ hours until it has doubled in size.
After the first rise, grease an 8-inch cake pan and punch down the dough to release excess gas. Knead ⅓ cup + 1 tablespoon (55g) pitted and chopped black olives and ½ cup (55g) finely grated Parmesan directly into the dough, distributing them evenly throughout.
Divide the dough into 12 equal balls and arrange them in a circular pattern within the prepared pan. Cover the pan and let the balls proof for 30 minutes until they've risen and are touching slightly.
When ready to bake, preheat your oven to 425°F. Brush the tops of the dough balls with 1 beaten egg and sprinkle ¼ cup (30g) sharp, grated Cheddar over the entire crown. Bake for 25–30 minutes until the loaf is golden brown and risen.
Once baked, transfer the crown loaf to a wire rack to cool completely before serving.
