Place a heavy covered dutch oven or bread baker in the oven and preheat to 500°F/260°C.
Remove bowl with dough from fridge if you did an overnight rise (no need to let it come to room temp first).
Gently invert it onto a piece of parchment paper so the seam side is down.
Once oven is hot, carefully slide the rack out and uncover the dutch oven.
Dust the bottom of the dutch oven or bread baker with flour (not needed if using parchment).
Score the top of the dough with a serrated knife or bread lame.
Carefully place the dough into the hot oven.
Cover the dutch oven and slide it back in the oven.
Turn the oven temperature down to 450°F/232°C.
Bake covered for 15 minutes.
Remove the lid from the dutch oven/bread baker and bake for an additional 13 to 15 minutes until the loaf is golden brown. Thump the bottom of the loaf. If it sounds hollow all the way through, it is done. If it sounds "wet" or solid, bake a few more minutes and check again.
Remove bread from oven and dutch oven, and let cool on baking rack for at least 90 minutes.
