- 2 cups unbleached all-purpose flour, or unbleached bread flour (see Note), plus more as needed
- 1 cup whole-wheat flour, or white whole-wheat flour
- 4 tablespoon good-quality grated Parmesan cheese, divided
- 1 teaspoon table salt
- 1 1/2 teaspoons instant, quick-rising or bread-machine yeast
- 1 1/2 cups ice water, (see Tip), plus more as needed
- 2 tablespoon chopped fresh oregano, chives or rosemary, divided
- 2 teaspoons extra-virgin olive oil
- 2 teaspoons fennel seeds, (optional)
- 1/2 teaspoon sea salt, or other coarse salt
Mix dough: Thoroughly stir 2 cups all-purpose (or bread) flour, whole-wheat flour, 3 tablespoons Parmesan, the table salt and yeast in a 4-quart (or larger) bowl. Vigorously stir in 1 1/2 cups ice water, scraping down the sides and mixing just until the dough is thoroughly blended. The dough should be barely moist and fairly stiff. If the mixture is too dry, stir in just enough additional ice water to facilitate mixing, but don’t overmoisten. If the dough is too wet, stir in just enough flour to stiffen slightly. Lightly coat the top with oil. Cover the bowl with plastic wrap.
First rise: Let the dough rise at room temperature (about 70°F) for 12 to 18 hours; if convenient, stir once partway through the rise. For convenience (and improved flavor), you may refrigerate the dough for 3 to 12 hours before starting the first rise.
Second rise: Coat a 9-by-13-inch (or similar) baking pan with oil, then line it with a sheet of parchment paper. Lightly coat the paper with oil. Stir the dough just until deflated. If it is soft, stir in just enough all-purpose (or bread) flour to yield a firm but moist dough (it should be fairly hard to stir). Sprinkle 1 tablespoon chopped herbs over the dough (don’t stir them in), then invert the dough into the pan so the herbs are underneath. Drizzle the dough with 2 teaspoons olive oil. With well-oiled hands, lightly pat and press the dough out until it fills the pan and is evenly thick; if it springs back and is resistant, let it rest for 10 minutes, then proceed. Sprinkle with the remaining 1 tablespoon Parmesan and herbs, and fennel seeds (if using), and pat down. Tent the pan with foil.
Let rise at warm room temperature until the dough is double the deflated size, 1 1/2 to 2 1/2 hours. (For an accelerated rise, see Tip.)
20 minutes before baking: Position a rack in lowest part of oven; preheat to 500°F. Lightly spritz or sprinkle the dough with water. With oiled fingertips, make deep indentations, or dimples, all over the top. Sprinkle evenly with sea salt (or other coarse salt).
Bake, cool, slice: Reduce oven temperature to 475°. Bake on the lowest rack, turning the pan from front to back halfway through for even browning, until golden brown and an instant-read thermometer inserted into the center registers 204-206°, 25 to 30 minutes. Cool in the pan on a wire rack for 10 to 15 minutes before slicing. Best served warm.
