If using a DUTCH OVEN, carefully remove the lid using pot holders or oven mitts and set the lid aside on a heatproof surface.
At this point, if you wish, you can make some slashes on the top of the dough to create a pattern. Alternatively, you can simply allow the dough to crack in its own pattern to create a bread with a very rustic appearance.
Lift the dough using the parchment paper, and transfer the dough down into the dutch oven along with the parchment paper. Cover the dutch oven, and using pot holders or oven mitts, place the lid back on to the dutch oven and return it to the oven. Close the oven door and allow the bread to bake - covered - at 450°F for 30 minutes.
After 30 minutes, remove the dutch oven from the oven using pot holders or oven mitts and transfer the dutch oven to a heatproof surface on your counter. Remove the lid using pot holders or oven mitts and place the lid on a heatproof surface.
Carefully, again using pot holders or oven mitts, remove the bread from the dutch oven by lifting the parchment paper and placing the bread on the counter. Remove the parchment paper and return the bread to the dutch oven, using pot holders or oven mitts, and then return the dutch oven without the lid back to the oven.
Close the oven door and allow the bread to bake for an additional 5 minutes until golden brown on top.
