Overnight Sourdough: A Master Class
A simple, no-knead method that does its best work while you sleep. A long overnight fermentation builds the deep, tangy flavor and open crumb people spend years chasing, and the Dutch oven does the rest with almost no effort from you in the morning.

Why This Recipe Works
An overnight rise gives sourdough time to develop flavor without requiring a full day of active work. The dough should look aerated and noticeably expanded by morning, with bubbles across the surface. Room temperature matters more than an exact clock, so a cool kitchen may need additional time.
Shaping is intentionally gentle. The goal is to create surface tension without pressing out all of the gas that developed during fermentation. If the dough feels slack, use a light dusting of flour and a bench scraper instead of adding large amounts of extra flour, which can make the loaf dense.
A preheated Dutch oven traps steam during the first part of the bake, helping the loaf expand before the crust sets. Remove the lid for the final stretch so the crust can deepen in color. Let the loaf cool before slicing; cutting too early releases steam and can leave the crumb gummy.
Variation Ideas
- Replace 100g of the bread flour with whole wheat or rye for a darker crumb.
- Fold in toasted walnuts and chopped rosemary before shaping.
- Add 50g of cooked, cooled grains for a chewier, more rustic loaf.
- Bake two smaller boules instead of one for a thinner, crisper crust ratio.
Ingredient Substitutions
- Bread flour
- Swap 100g for whole wheat or rye for a darker, tangier crumb
- Sourdough starter
- 1/4 tsp instant yeast plus a 2-hour rise, if your starter is sluggish
- Dutch oven
- A heavy cast iron skillet covered with a stainless bowl for the first 20 minutes
- Fine sea salt
- Kosher salt, measured by weight rather than spoonfuls
Frequently Asked Questions
How do I know the overnight rise is actually done?
Look for a domed, bubbly surface and dough that has grown by about half again in volume. Poke it: the dent should spring back slowly and only part of the way. A dent that stays put means it has gone too far.
How long will this bread last?
Cut side down on a board it stays good for 2–3 days. After that, slice and freeze in a bag for up to 3 months.
How should I reheat or refresh a loaf?
Toast frozen slices straight from the freezer, or run a whole day-old loaf under the tap for a second and bake it at 375°F for 8 minutes to bring the crust back.
Can I slow the dough down and bake later?
Yes — after shaping, refrigerate the loaf overnight and bake it cold the next day. The flavor deepens and the scoring is cleaner on chilled dough.
