Start by combining water, yeast, sugar and salt in a large mixing bowl. Allow to sit for 5-10 minutes. Yeast should become foamy on top of water.
Begin adding in flour 1 cup at a time. After each cup, mix well with a large spoon or dough whisk to incorporate.
Once dough is has formed (it will be a sticky, shaggy dough), cover the bowl with plastic wrap or damp tea towel. Allow to rise 1-3 hours. Dough should double in size during this time.
Before you start to shape your loaf, preheat the oven to 450 degrees with dutch oven inside.
Flour a worksurface and dump your dough out. This dough is sticky, so be generous with the flour. Begin to shape the dough into a round loaf by forming a ball. I like to twist the dough on the worksurface to smooth the bottom seams out.
Place the formed dough onto parchment paper and transfer into dutch oven. Bake with the lid on for 30 minutes. Remove lid and bake additional 10 minutes.
Allow bread to cool before slicing.
