How to Bake Sourdough Without a Dutch Oven

A Dutch oven is convenient, but it's not magic. The thing it actually does — trap steam around the loaf for the first 20 minutes — can be done five other ways with gear you probably already have.

Why steam matters

Steam keeps the surface of the loaf flexible during oven spring. Without it, the crust sets too early and the loaf can't expand. The result is a denser bread with cracks instead of a smooth, blistered crust.

You need steam for the first 15–20 minutes. After that, you want it gone so the crust can brown.

Method 1: Cast iron skillet with boiling water

Most reliable no-Dutch-oven method.

• Place a cast iron skillet on the bottom rack while preheating
• Bake the loaf on a sheet pan or stone above
• When the bread goes in, pour a cup of boiling water into the skillet
• Close the door fast

Remove the skillet (carefully) at 20 minutes to let the crust set.

Method 2: Two sheet pans

Use a second sheet pan as a lid.

• Bake the loaf on a parchment-lined sheet pan
• Cover with an inverted second sheet pan, leaving a small gap
• Trapped steam from the dough does the work
• Uncover at 20 minutes

Best for batards or small boules. Doesn't work well for larger loaves that need more clearance.

Method 3: Lava rocks or chains

Add thermal mass that holds water.

• Place lava rocks or a steel chain in a metal pan on the bottom rack
• Preheat
• Pour boiling water over them when the bread goes in

The high surface area produces lots of steam fast.

Method 4: Ice cubes

Quickest method, less effective.

• Drop a handful of ice cubes onto a preheated cast iron pan when the bread goes in
• Steam ramps up gradually as they melt

The downside is your oven temperature drops more from cold ice than from boiling water.

Method 5: Roasting pan as a lid

If you don't have a Dutch oven but have a deep roasting pan, invert it over the loaf on a stone or steel.

• Preheat the roasting pan upside down on the stone
• Place the dough on parchment, slide it under
• Cover with the hot roasting pan
• Remove at 20 minutes

Functionally identical to a Dutch oven if the seal is decent.

What to avoid

Spraying water with a spray bottle — barely registers as steam and rapidly cools the oven.

Wet towels — fire hazard.

Bowl over the loaf — pyrex can shatter, ceramic can crack.

Picking the best for your kitchen

If you bake one loaf at a time, the cast iron skillet method is the closest to Dutch oven results without the cost.

If you bake multiple loaves, two sheet pans or a roasting pan lid scales better.

A Dutch oven is convenient. But if you have a working oven and a sheet pan, you have everything you need.
