In a large bowl, whisk together the flour, salt, and yeast.
Pour in the lukewarm water and mix with a spoon or spatula until just combined. The dough will be shaggy and sticky.
Cover the bowl with plastic wrap or a clean kitchen towel and let it rest at room temperature for at least 8 hours, or up to 18 hours.
After the resting period, the dough will be bubbly and have increased in volume. Turn the dough out onto a well-floured surface. Gently shape it into a ball, being careful not to deflate it too much.
Place the dough ball on a piece of parchment paper. Let it rest, uncovered, for about 30 minutes while you preheat your oven and a Dutch oven.
Preheat your oven to 450°F (230°C). Place an empty Dutch oven with its lid on into the preheated oven for at least 30 minutes.
Carefully remove the hot Dutch oven from the oven. Remove the lid. Using the parchment paper, carefully lower the dough into the hot Dutch oven.
Cover the Dutch oven with the lid and place it back into the oven. Bake for 30 minutes.
Remove the lid from the Dutch oven and continue baking for another 10-15 minutes, or until the crust is golden brown and the internal temperature of the bread reaches 200-210°F (93-99°C).
Carefully remove the bread from the Dutch oven and place it on a wire rack to cool completely before slicing.
Notes
This bread is best enjoyed fresh. It can be stored in a bread box for a day or two. For longer storage, slice and freeze.
