01 - Whisk together flour, salt, and yeast in a large mixing bowl until thoroughly blended.
02 - Add lukewarm water and stir with a wooden spoon until a shaggy, sticky dough forms. Do not overmix.
03 - Cover bowl tightly with plastic wrap and let rest at room temperature for 12-18 hours until surface is bubbly and dough has doubled.
04 - Scrape dough onto floured surface and gently shape into a ball with floured hands, handling minimally to preserve air pockets.
05 - Place dough seam-side down on parchment paper dusted with flour or cornmeal. Cover and rest for 30-60 minutes.
06 - Place Dutch oven with lid in oven and preheat to 450°F for at least 30 minutes to ensure proper heat retention.
07 - Carefully remove hot Dutch oven. Lift dough using parchment paper and place into pot with paper included. Cover immediately with lid.
08 - Bake covered for 30 minutes to create steam and develop crust structure.
09 - Remove lid and bake 12-15 minutes until deep golden brown and crusty. Internal temperature should reach 200-205°F.
10 - Transfer loaf to wire rack and cool completely before slicing to prevent gumminess—minimum 1 hour.
