Add warm water to a large bowl or food-grade container. Add yeast and stir to combine.
Add flour and salt and stir until all ingredients are incorporated. It may get sticky, so you can always get in there with your hands to give it a good mix. But remember, you don’t need to knead the dough, just mix until combined.
Cover your container with a lid, or with a piece of plastic wrap and a towel and leave at room temperature for 2 hours.
Transfer the dough to the refrigerator and let it rest until you’re ready to bake. The dough can be stored in the refrigerator for up to two weeks.
An hour and a half before you’re ready to eat. Take a grapefruit-sized section of your dough out of the container in the refrigerator. Place the remaining dough back in the fridge.
Generously flour a banneton basket, if using, with rice flour (or regular flour). Alternatively, place a piece of parchment paper on the counter.
Stretch the grapefruit-sized section of dough, folding it in and under, then pinching the sides together on the bottom until a nice round loaf is formed.
Place top-side down in your banneton, cover with a towel and allow to rise for 40 minutes.
About 20 minutes into the rise time, preheat the oven to 425°F with the Dutch oven inside the oven.
Place a piece of parchment paper over your banneton and gently flip the loaf over so your loaf is now on the parchment and out of the basket.
Remove the hot Dutch oven from the oven and gently lift parchment paper and loaf, then lower into the Dutch oven.
Cover with the lid and bake for 30 minutes.
Remove the Dutch oven lid and continue baking for a few more minutes until the bread is golden brown on top.
Remove the bread from the Dutch oven and place it on a cooling rack for a few minutes before slicing. Serve warm.
