Preheat a dutch oven to 500 degrees for 1 hour.
Remove dough from the fridge right before baking. Place dough on a piece of parchment paper.
Dust with flour, if desired, and score with lame or razor blade. I like to do one large score (called an expansion score) and then a cute design for the other score.
Carefully, transfer the piece of parchment paper with the dough into the hot dutch oven. Careful not to burn your fingers.
Place the lid back on and place the dutch oven into the hot oven. Bake for 20 minutes.
Remove the lid with oven mitts, turn the oven temperature down to 475, and bake an additional 15-25 minutes or until golden brown.
