In a large mixing bowl, combine the 3 cups of all-purpose flour, 2 teaspoons of active dry yeast, and 2 teaspoons of salt. Stir gently until well mixed.
Pour in the 1 1/2 cups of lukewarm water and use a wooden spoon to mix until a shaggy dough forms. Don’t worry about lumps!
Cover the bowl with a kitchen towel and let the dough rise at room temperature for about 12 to 18 hours.
About 30 minutes before you're ready to bake, preheat your oven to 450°F (232°C) with your Dutch oven inside.
Once the dough has risen, turn it out onto a floured surface and shape it into a ball.
Let the shaped dough rest for about 30 minutes while your Dutch oven continues to heat.
Carefully remove the hot Dutch oven from the oven. Using parchment paper, lift the dough and place it inside. Cover with the lid and bake for 30 minutes.
After 30 minutes, remove the lid and bake for an additional 15-20 minutes until the crust is golden brown and crispy.
Remove the bread from the Dutch oven and let it cool on a wire rack.
