Baking Sourdough in a Dutch Oven (with Steam)

A Dutch oven is the simplest way to get bakery-quality sourdough at home. It turns an ordinary oven into a steam-injected one for free — no water trays, no ice, no fuss — and it’s the single biggest upgrade most home bakers can make to their crust and oven spring.

Why a Dutch oven works

The magic is steam. In the first minutes of baking, a wet dough releases moisture. Inside a sealed, preheated Dutch oven that moisture is trapped as steam, and steam is what makes a great loaf.

Steam keeps the crust soft and flexible for those crucial early minutes, letting the loaf expand fully — that dramatic rise is called oven spring. It also gelatinises the surface starches, which then dry into a thin, glossy, crackly crust. A home oven leaks steam instantly; a Dutch oven holds it right against the loaf.

Preheat the pot — hard

Preheating the empty pot is non-negotiable for the classic result. A hot pot flash-heats the dough surface and drives the spring.

230–260°C preheat temperature

30–60 min preheat time (empty pot)

96–99°C target internal when done

Put the Dutch oven in cold and let it come up with the oven, then hold it at temperature for at least 30 minutes. It should be thoroughly hot — the metal, not just the air around it.

The two phases: lid on, lid off

Every great Dutch oven bake is really two bakes — a steamy one and a dry one.

1
Score and load Score your cold, proofed dough and lower it into the hot pot (a parchment sling makes this safe and easy).
2
Lid ON — the steam phase Bake covered for the first ~20 minutes. Trapped steam keeps the crust soft so the loaf springs to its full height.
3
Lid OFF — the browning phase Remove the lid and bake another 20–25 minutes. The crust now dries, deepens to golden-brown, and crisps up.
4
Optional temperature drop If you preheated very hot, drop to 220–230°C when the lid comes off to brown evenly without scorching.

The ice-cube myth

A popular tip says to toss ice cubes into the Dutch oven for extra steam. Don’t.

×The dough already provides plenty of steam inside the sealed pot — extra water adds nothing
×Ice or water on hot enamelled cast iron can thermal-shock and crack the enamel
×Glass lids are especially prone to shattering from the sudden temperature change
×It adds a fiddly, hazardous step for zero benefit

The closed lid is your steam source. Let the loaf steam itself.

Loading the dough safely

The pot is 250°C and heavy — a moment of planning keeps your knuckles intact and your loaf round.

Use a parchment sling Turn the dough onto a square of parchment, score it, then use the paper as a sling to lower it in and lift it out. No burns, no deflated dough.

Score cold and confident Cold dough from the fridge holds its shape and takes a clean, deep score. One decisive slash at a shallow angle gives the best ear.

Mind the bottom heat If your base tends to scorch, sit a spare tray on the rack beneath the pot to buffer the direct heat.

Knowing when it's done

Judge by colour and temperature, not by the timer. The crust should be a deep golden-brown to mahogany — a pale loaf is underbaked and will taste flat. Confirm with an instant-read thermometer: 96–99°C (205–210°F) in the centre. A finished loaf sounds hollow when you tap its base.

Then the hardest step: let it cool completely on a rack, ideally 1–2 hours, before slicing. The crumb is still setting as it cools, and cutting early leaves it gummy.

Troubleshooting

×No oven spring → pot not hot enough, or dough over-proofed
×Pale, soft crust → lid left on too long, or oven ran cool
×Burnt base → add a buffer tray below, or drop the temperature after lid-off
×Gummy crumb → underbaked or sliced warm; bake to 96°C+ and cool fully
×Dough sticks to the pot → use parchment; never load a bare, wet dough into dry cast iron

Frequently asked questions

Do I need to preheat the Dutch oven?+

Yes. Preheating the empty Dutch oven for 30–60 minutes at 230–260°C (450–500°F) is essential. A screaming-hot pot flash-heats the dough surface and drives the oven spring. Loading dough into a cold pot gives a flat, pale loaf. The one exception is a cold-start method, but for the classic result, preheat fully.

When do I take the lid off?+

Bake with the lid on for the first ~20 minutes. During this phase the dough releases moisture that's trapped as steam, keeping the crust soft so the loaf can expand. Then remove the lid for the final 20–25 minutes so the crust can dry, brown, and crisp. Removing it too early stops the spring; leaving it on too long gives a pale, soft crust.

Should I add ice cubes to my Dutch oven?+

No — it's unnecessary and risky. The dough itself gives off plenty of steam inside the sealed pot, so extra water adds nothing. Worse, dropping ice or water onto hot enamelled cast iron or a glass lid can thermal-shock and crack it. Skip the ice; the closed lid does the job.

What temperature should I bake sourdough at?+

Most sourdough bakes well at 230°C (450°F). Many bakers preheat higher (250–260°C) then drop to 220–230°C after removing the lid to brown without burning. Total bake time is usually 40–45 minutes. Color matters more than the clock — aim for a deep golden-brown crust.

How do I know when the bread is done?+

Use color and internal temperature. The crust should be deep golden to mahogany, and the internal temperature should read 96–99°C (205–210°F) on an instant-read thermometer. A well-baked loaf also sounds hollow when tapped on the base. If in doubt, bake a few minutes longer — underbaked sourdough is gummy.

Why is the bottom of my loaf burning?+

Enamelled cast iron concentrates heat at the base. Fixes include placing a baking tray or pizza stone on the rack below the Dutch oven, sliding a second sheet under the pot, using a sheet of parchment plus a sprinkle of semolina, or lowering the oven temperature slightly after the lid comes off.

Can I bake cold dough straight from the fridge?+

Yes, and it's often better. Baking cold, retarded dough straight from the fridge gives firmer dough that scores cleanly and holds its shape, and it bakes through fine. There's no need to let it come to room temperature first — score it cold and load it into the hot pot.
