This is our everyday loaf — the one we bake every single week, no matter what else is going on. It's 20% whole wheat, naturally leavened with a starter that's been alive since 2021, and built around one long, slow, 18-hour cold ferment that does most of the actual work while we sleep.
There's nothing hidden about this recipe. No commercial yeast, no shortcuts, no dough conditioners — just flour, water, salt, and time. The long fermentation is what gives it that open, irregular crumb and the deep, almost blistered crust, and it's also what makes it easier on digestion than a same-day loaf for a lot of people.
Why the cold ferment matters
Retarding the dough in the fridge overnight isn't just about convenience (though it helps — you shape it the night before and bake first thing in the morning). The cold slows fermentation down without stopping it, giving the wild yeast and bacteria in the starter much longer to develop flavor and to break down some of the starches and phytic acid in the flour. The payoff is a loaf that tastes more complex than the time in the kitchen would suggest.
Ingredients & Nutrition
Instructions:
- Feed your starter the night before, and let it become bubbly and active — it should roughly double and float in water when it's ready.
- Mix the bread flour, whole wheat flour, and water together until no dry flour remains. Let it rest (autolyse) for 30 minutes.
- Add the active starter and salt, and mix until fully incorporated.
- Bulk ferment at room temperature for 3–4 hours, folding the dough over itself every 30 minutes for the first two hours.
- Shape the dough into a tight boule and place it seam-side up in a floured banneton or bowl lined with a floured towel.
- Cold retard in the refrigerator for 12–18 hours.
- Preheat your oven to 500°F (260°C) with a Dutch oven inside for at least 30 minutes.
- Score the cold dough, then bake covered for 20 minutes, remove the lid, and bake another 20–25 minutes until deeply golden.
- Cool completely on a wire rack — at least an hour — before slicing, so the crumb has time to set.
Reading your starter correctly
The single biggest factor in whether this loaf turns out well isn't the recipe — it's whether the starter was actually ready when it went into the dough. A starter that's ready should have roughly doubled in size, look domed and bubbly rather than flat or sunken, and pass the float test: drop a small spoonful into a glass of water, and it should float rather than sink. A starter used too early (before it's fully risen) or too late (after it's already collapsed back down) will leaven the bread noticeably less, no matter how carefully the rest of the recipe is followed.
Tips for success
Use a kitchen scale, not cups, for the flour and water. Bread recipes are far more consistent by weight, since a "cup" of flour can vary by as much as 20% depending on how it's scooped.
Don't skip the autolyse. That 30-minute rest after mixing flour and water (before adding starter and salt) lets the flour fully hydrate, which makes the dough noticeably easier to work with and improves the final crumb structure.
Watch the dough, not just the clock. Bulk fermentation times shift a lot with kitchen temperature — a dough in a 65°F kitchen will take meaningfully longer to rise than one in a 75°F kitchen. Look for the dough to be visibly puffy and jiggly, roughly 30-50% larger, rather than strictly following a timer.
Score with confidence. A hesitant, shallow score won't let the bread expand properly in the oven. One clean, fairly deep cut (about ½ inch) at a slight angle gives steam a clear path to escape and produces that classic "ear" on the crust.
Troubleshooting
My loaf came out flat and dense. This is almost always an underproofed or underactive starter — see the starter section above. It can also happen from underproofing the bulk ferment, pulling the dough into the fridge before it had risen enough.
My crust is pale, not deeply golden. Make sure the Dutch oven is fully preheated (a full 30 minutes at 500°F) before the dough goes in — a cool baking vessel is the most common cause of a pale, soft crust.
Storage
Once fully cooled, this loaf keeps at room temperature, cut-side down on a board or in a paper bag, for about 3 days — it's naturally leavened bread, so it doesn't mold as quickly as commercially yeasted loaves but will gradually stale. For longer storage, slice and freeze; individual slices toast well straight from frozen.
