Crusty Boule (Round Loaf)
The boule—literally a ball—is the oldest shape of bread. It's also one of the easiest to master because the round form contains itself; there's no long edge to deflate or corners to square off. What makes it sing is steam and time. The overnight cold fermentation develops flavor while making the dough easier to handle. The Dutch oven does the work: it traps the moisture released by the dough as it bakes, keeping the crust flexible just long enough to expand, then letting it dry out into something that crackles when you break it.
This is a long ferment. Plan for overnight.
You'll mix the dough in the morning or afternoon, let it rest in the cold overnight, then shape and bake the next day. The cold fermentation is not a workaround—it's the whole point. It develops flavor and makes the dough stable enough to shape without tearing.

- 350 gwater, room temperature
- 10 gsalt
- 1/4 tspinstant yeast or active dry yeast
Shaping Tension Into the Surface
The boule must be shaped with enough surface tension that it holds its round form in the oven. Too loose, and it spreads into a disk. Flour your work surface lightly, flip the bulk dough seam-side down, then pull the edges toward the center and under itself in a circular motion, rotating the ball a quarter turn each time. Do this until the surface feels taut. Place it seam-side up in a floured banneton. The tension you build now determines the spring and the crust break in the oven.
The method.
Mix the dough.
Combine flour, water, salt, and yeast in a large bowl. Stir until no dry flour remains. The dough will look shaggy and loose. This is right. Cover the bowl and let it sit at room temperature for 30 minutes.
Fold in the strength.
Wet your hand. Grab one side of the dough, stretch it up and fold it over the center. Rotate the bowl a quarter turn and repeat. Do this 4 times. You're not kneading—you're gathering the gluten into alignment. The dough will feel tighter. Do this folding routine three more times over the next 2 hours, spaced 30 minutes apart.
Cold ferment overnight.
After the last fold, cover the bowl and refrigerate for 12 to 16 hours. The cold slows fermentation and gives flavor time to develop. The dough will rise slightly but not dramatically. This is normal.
Shape the boule.
Remove the dough from the fridge. Flour your work surface lightly. Turn the dough out seam-side down. Using the shaping technique described above, pull the edges toward the center and under itself in a circular motion until the surface is taut. Place the boule seam-side up in a floured banneton or in a bowl lined with a floured kitchen towel.
Final proof.
Cover the banneton loosely. Let the boule proof at room temperature for 2 to 3 hours. It should increase in volume by about 50 percent and feel pillowy. To test, poke it gently with your finger. The dent should spring back slowly, not immediately and not at all.
Preheat the Dutch oven.
Place a Dutch oven (lid on) in your oven and heat to 500°F for 45 minutes. This is not optional. A screaming-hot Dutch oven is what creates the steam barrier.
Score and bake covered.
Carefully remove the Dutch oven from the oven. Turn your proofed boule out onto parchment paper. Using a sharp knife or bread lame, make one confident slash across the top, about 1/4 inch deep and 5 inches long. Slide the parchment into the Dutch oven. Cover with the lid. Bake at 500°F for 20 minutes.
Finish uncovered.
Remove the lid. Lower the heat to 450°F and bake for another 25 to 30 minutes. The crust should deepen to a dark mahogany brown. The loaf will sound hollow when tapped on the bottom. If it's still pale, give it another 5 minutes.
Cool completely.
Turn the boule onto a wire rack. Wait at least 1 hour before slicing. The crumb is still setting as it cools. Cutting into a warm loaf will compress it and make it gummy.
Other turns to take.
Whole Wheat Boule
Replace 150 g of bread flour with whole wheat flour. Whole wheat absorbs more water, so increase water to 365 g. The fermentation time stays the same, but the crumb will be denser and more structured. The flavor deepens.
Boule with Seeds
Before the final proof, brush the shaped dough lightly with water and roll it in a mix of sesame, poppy, and sunflower seeds. The seeds toast in the oven and add texture and flavor. Don't skip the water—without it, the seeds won't adhere.
Faster Boule (Same Day)
If you don't have time for an overnight ferment, you can proof at room temperature instead. Mix and fold as described, then let the dough bulk-ferment at room temperature for 5 to 6 hours instead of overnight. Shape and proof for 3 to 4 hours. The flavor will be less complex, but the bread will still be good. This is not ideal, but it works.
When it doesn't go to plan.
Water temperature matters more than you think. Cooler water (around 65°F) slows fermentation and extends flavor development. If your kitchen is warm, use water straight from the fridge.
The boule is done when the bottom sounds hollow when tapped and the crust is deep brown, almost to the point of seeming dark. A pale crust means weak steam circulation or insufficient baking. Dark is right.
Don't rush the cool. A hot loaf continues to cook internally and the crumb structure is still setting. Cutting into it releases steam that should be staying in the bread. One hour is a minimum.
If you don't have a banneton, line any small bowl with a kitchen towel and flour it well. The shape doesn't need to be perfect—the boule will round itself in the oven.
Your Dutch oven must have a lid. An uncovered bake will produce a crispy crust, but not the kind that shatters. The lid traps steam, which is the whole point.
The ones that keep coming up.
Why does my boule spread instead of rise?
The dough wasn't shaped with enough tension, or it over-proofed. When you shape, pull the edges toward the center firmly enough that the surface feels tight. During the final proof, watch for the 50 percent rise, not more. If the dough is sagging by the time you bake it, it's overproofed.
Can I skip the overnight fermentation?
Not really, if you want flavor. You can do a same-day ferment at room temperature (see variations), but the cold fermentation develops complexity that fast fermentation doesn't. The cold also makes the dough easier to handle. If you're in a hurry, the faster version works, but the bread won't be as good.
What if I don't have a Dutch oven?
You need one. A regular baking pan won't trap steam the way a sealed Dutch oven does, and steam is what makes the crust shatter. You can find Dutch ovens cheaply at homeware stores. They last forever.
How do I know when the boule is done baking?
Tap the bottom. It should sound hollow, like knocking on wood. The crust should be dark brown. If you're unsure, use an instant-read thermometer: the internal temperature should be around 205 to 210°F. But the tap test is reliable.
Can I freeze a shaped boule before baking?
Yes. After shaping, wrap it tightly in plastic wrap and freeze. When ready to bake, move it to the fridge to thaw overnight, then proof at room temperature for 1 to 2 hours before baking. Freezing pauses fermentation; thawing restarts it slowly.
