In a bowl mix together the flour, yeast, salt, and water. Make sure the water is WARM – not too hot and not too cold.
Stir it together really well. It will look like a shaggy mess – not like a smooth, ball of bread.
Put a piece of plastic wrap over the bowl and let it sit for 8-24 hours, or overnight.
When you have let it sit long enough, whether that’s all day or overnight, scoop the dough out onto a floured surface. Form it into a nice ball and let it sit for 45 minutes.
Now gently pick up the bread dough and then drop it gently into the dutch oven. Put the lid back on and put it in the oven to bake for 40 minutes.
After the 40 minutes take the lid off and bake for another 10 minutes.
Take it out of the oven, and let it cool for a good hour.
