Baking sourdough bread in a Dutch oven traps steam around the dough, creating a crisp, deep-brown crust and a chewy interior with good oven spring.
A Dutch oven is the closest thing a home baker has to a professional steam-injected oven. The heavy lidded pot holds the moisture released by the dough as it bakes, which keeps the surface gel-like long enough for the loaf to expand fully before the crust sets. That expansion — called oven spring — gives you the tall, round loaf and the open crumb structure sourdough is known for. The method below follows a lean, no-knead rhythm that works with any sourdough starter and a hot oven.
What You Need Before You Start
You need an active sourdough starter (fed and bubbly), bread flour, whole-wheat or all-purpose flour works too), water, and fine sea salt. You also need a lidded Dutch oven — enameled cast iron or bare cast iron both work. If your Dutch oven has a plastic or wood handle knob, check the manufacturer’s heat limit before preheating above 450°F; many can handle 500°F, but some cannot. The pot should be at least 5 quarts so the loaf has room to rise without touching the lid.

The Mixing and Bulk Fermentation Steps
Mix 100 grams of active starter with 350 grams of warm water in a large bowl. Add 500 grams of bread flour and 10 grams of fine sea salt. Stir until no dry flour remains and a shaggy, sticky dough forms. Cover the bowl and let it rest for 30 to 45 minutes — this autolyse period lets the flour fully hydrate and starts gluten development.
Over the next 2.5 to 3 hours, perform stretch-and-folds every 20 minutes or so. Wet one hand, reach under one side of the dough, lift it up, and fold it over the middle. Turn the bowl a quarter turn and repeat three more times to complete one set. Do four sets total. After the last fold, let the dough sit undisturbed until it has doubled in size and feels pillowy and bubbly — this can take 4 to 6 hours at room temperature. The exact time depends on your starter strength and kitchen warmth; a finger-dent test that springs back slowly tells you bulk fermentation is done.
Shaping, Proofing, and Scoring
Turn the dough onto a lightly floured surface. Gently flatten it into a rectangle, then fold the left third over the middle and the right third over that. Roll the dough toward you into a tight ball, pinching the seam closed. Place the loaf seam-side up in a well-floured banneton or a bowl lined with a floured tea towel. Cover and refrigerate overnight for a cold proof, or let it proof at room temperature for 1 to 2 hours until it puffs and passes the finger-dent test.
When ready to bake, place your Dutch oven on the center rack and preheat the oven to 450°F for at least 30 minutes. If your pot can handle it, 500°F for 45 minutes gives even better spring. Turn the dough onto a sheet of parchment paper, seam-side down now, and score the top with a sharp lame, razor, or knife. Cut about ½ inch deep in a single confident stroke — a shallow score keeps the loaf from tearing open at weak spots.
Baking and Cooling
Carefully remove the hot Dutch oven, place the parchment with the dough inside, and cover with the lid. Bake at 450°F for 20 minutes covered. The lid traps the steam. Then remove the lid and bake another 20 to 25 minutes until the crust is a deep mahogany brown. An instant-read thermometer inserted through the bottom should read 205 to 210°F.
Lift the loaf out of the pot and transfer it to a wire rack. Cool completely — at least 45 minutes, ideally 2 hours. Cutting while warm compresses the crumb and leaves it gummy. The crust continues to crisp as it cools.
FAQs
Why does my sourdough not rise in the Dutch oven?
Insufficient preheat is the most common cause. If the pot is not fully hot when the dough goes in, the steam never forms quickly enough, and the loaf sets before it can expand. Also check your dough for signs of underproofing or overproofing — either one kills oven spring.
Can I use a ceramic or glass dish instead of a Dutch oven?
Most ceramic and glass baking dishes cannot handle the high preheat temperature safely. Use a heavy covered pot that is rated for at least 450°F, such as an enameled or bare cast-iron Dutch oven. A stainless steel pot with a tight lid also works if it has an oven-safe handle.
How do I keep the bottom crust from burning?
A thin layer of cornmeal or semolina under the dough creates a small air gap. You can also place a baking sheet on the rack below the Dutch oven during uncovered baking to diffuse the bottom heat without affecting the top browning.
