After 8-12 hours have passed, preheat your oven to 450F with the Dutch oven inside for 15 minutes.
While you are waiting for the oven to preheat, use a piece of parchment paper to flip the dough out of the banneton. The dough should be facing up now. Using a sharp knife or a bread lame, make a slit in the top of the dough.
Once the oven has preheated, lower the dough into the Dutch oven using the parchment paper. Spray or sprinkle some water around the sides (this helps with steam to get that perfect bubbly & crispy crust.)
Place the lid on the Dutch oven and bake the bread for 30 minutes. Once 30 minutes have passed, remove the lid and bake for another 15 minutes.
Once the time is up, remove the Dutch oven from the oven, and then lift the bread out of it using the parchment paper.
Allow the bread to cool completely before slicing open.
Slather on some butter and enjoy a delicious slice of gluten-free sourdough!
