- 375g warm water
- 500g bread flour
- 10g fine sea salt
Optional
- Rice flour for dusting
- Extra bread flour for shaping

Instructions
Step 1: Mix the Dough
In a large bowl, combine the active sourdough starter and warm water until mostly dissolved. Add the bread flour and mix until no dry flour remains. Cover the bowl and let it rest for 30 minutes. This rest period, called the autolyse, allows the flour to fully hydrate and helps develop gluten naturally.
Step 2: Add Salt
Sprinkle the salt over the dough. Wet your hands slightly and fold the dough over itself several times until the salt is fully incorporated. The dough will feel smoother after a few minutes of mixing.
Step 3: Stretch and Fold
Over the next 2 hours, perform four sets of stretch and folds every 30 minutes. Grab one side of the dough, stretch it upward without tearing, and fold it over itself. Rotate the bowl and repeat on all four sides.
Each round of folding strengthens the gluten and helps build structure without intensive kneading.
Step 4: Bulk Fermentation
Cover the dough and let it rise at room temperature for another 3 to 5 hours, depending on the temperature of your kitchen. The dough should become puffy, slightly domed, and increase by about 50%.
Avoid over-proofing, as this can reduce oven spring and result in a flatter loaf.
Step 5: Shape the Dough
Turn the dough onto a lightly floured surface. Gently shape it into a round by pulling the edges toward the center and tightening the surface against the counter.
Allow it to rest for 20 minutes.
Perform the final shaping by creating surface tension while maintaining the air inside the dough.
Step 6: Cold Proof
Place the dough seam-side up into a floured banneton basket.
Cover and refrigerate for 10 to 16 hours. This slow fermentation develops a deeper flavor and helps produce the signature crunchy crust.
Baking Instructions
Preheat
Place your Dutch oven inside the oven and preheat to 475°F (245°C) for at least 45 minutes.
A thoroughly heated Dutch oven creates steam instantly, which is the secret to an exceptional crust.
Score the Dough
Carefully remove the dough from the refrigerator and invert it onto parchment paper.
Dust lightly with flour if desired.
Using a bread lame or sharp razor, score one long slash about ½ inch deep across the top. Decorative scoring is optional.
Bake with Steam
Transfer the dough into the hot Dutch oven.
Cover with the lid and bake for 20 minutes.
Remove the lid and continue baking for 22–25 minutes, or until the crust is a deep golden brown with a rich caramel color.
For an even crunchier crust, crack the oven door open slightly during the final 5 minutes of baking.
Cooling
Remove the bread from the Dutch oven and cool completely on a wire rack for at least one hour.
Although it’s tempting to slice into warm bread, allowing it to cool lets the crumb finish setting and preserves the loaf’s texture.
Tips for the Crunchiest Sourdough
- Use a very active starter that doubles within 4 to 6 hours after feeding.
- Bread flour creates a stronger gluten network than all-purpose flour.
- Always preheat the Dutch oven thoroughly.
- Cold-proof the dough overnight for improved flavor and better scoring.
- Avoid adding too much flour during shaping.
- Bake until the crust is a rich, dark golden brown instead of a light tan.
- Let the loaf cool completely before slicing.
- Store the bread cut-side down on a wooden board to help maintain the crisp crust.
Storage
Store your sourdough at room temperature in a bread bag or wrapped in a clean kitchen towel for up to 3 days.
For longer storage, slice the loaf and freeze it in an airtight freezer bag for up to 3 months. Toast slices directly from frozen for fresh-baked flavor.
