SHEET PAN METHOD: Although we prefer the Dutch oven method, this recipe can be baked on a sheet pan. To bake on a sheet pan, cover loaf with foil and tightly seal foil around rim of pan. Bake at 425°F (220°C) for 30 minutes. Uncover and bake until an instant-read thermometer inserted in center registers 205°F (96°C), 10 to 15 minutes more.
