Cast Iron Dutch Oven: How to Bake Bread

Bread baked in a cast iron cauldron

From the Gauls to medieval peasants, and even transhumant shepherds in the 1930s, this method of baking bread has spanned centuries—simple, mobile, and effective.

But beware: baking bread in a cauldron is not the same as simmering a stew.

Fire: intense for bread, gentle for cooking

One of the key points is fire management:

  • For baking bread, the cauldron temperature must be high: around 240 °C.
    ➤ You need a strong fire, good embers underneath and on the lid to simulate a closed oven. The cauldron must be preheated over the flames to reach the right temperature.

  • For everyday cooking (stews, broths, porridges, etc.), it's the opposite: avoid flames.
    ➤ Cook on a bed of gentle embers, around 90–95 °C, for slow, even cooking, without burning. No flames!

Baking bread in a cast iron cauldron: operational summary

With this 3-legged cast iron cauldron with a lid, the goal is to recreate a small oven. This model works very well thanks to the raised edges of the lid, provided you manage the embers and preheating properly.

1. Prepare the fire

Build a good wood fire until you have a sufficient amount of red embers, not just flames.

You need:

an abundant bed of embers;

enough to add more during baking.

2. Preheat the cauldron

Place the empty, closed cauldron over the flames for 10 to 15 minutes.

With this very stable 3-legged model, it's possible to place it directly on the embers.

The goal is for the cast iron to be very hot before placing the dough inside. (~240°C inside the cauldron)

3. Protect the bottom

Before adding the dough, line the bottom with:

untreated cabbage, vine, lemon, or chestnut leaves;

or, more simply, straw or layers of parchment paper.

With this type of cauldron, this is very important, as the bottom heats up intensely.

Warning: some plants are toxic!

4. Place the dough ball

Gently place the dough into the hot cauldron.

Then:

score if you wish;

close immediately.

You need to lose as little heat as possible and retain moisture.

5. Arrange the embers for baking

With this suitable cauldron, do as follows:

a bed of embers underneath;

more embers on the lid.

The goal is to provide heat from both the top and bottom, without overheating the bottom.

Essential rule: don't put too many embers under the feet, otherwise the bottom will burn before the bread is properly cooked.

With this model, it's better to have:

moderate heat underneath;

more generous heat on the lid.

6. Cooking time

Generally allow 40 minutes.

Simple reference points:

at 20 minutes: check the embers;

at 25 minutes: slightly turn the cauldron if possible;

at 30 minutes: do a quick initial check;

at 40 minutes, it's cooked. Extend slightly if necessary.

7. How to tell if the bread is cooked

The bread is good if:

it has a well-formed crust;

it sounds hollow;

the underside is brown, not black.

Medieval bread baked in a cauldron

Three traditions of cauldron bread

- Among the Gauls

Bread was often made from spelt, barley, and millet flours. Fermentation was natural, using a sourdough starter, and baking took place in a cauldron lined with leaves or straw to prevent the bread's base from burning. The bread was dense, very lightly salted, but nutritious.

- In the Middle Ages

Cauldron-baked bread was mainly found among the humblest people or during military campaigns. A mix of barley and wheat was commonly used. Fermentation remained slow, using sourdough, but techniques became more refined. The addition of salt, which had significant market value, depended on available regions and resources – it wasn't systematic, and often less pronounced among the poorest.

- Among transhumant shepherds (1930s)

During their mountain travels, shepherds made bread directly in a cast iron cauldron over a bed of embers, using finer wheat flour and a little sourdough. It was a simple bread, quickly baked over a hot fire.

Where to get flour?

It is not easy to obtain wholemeal spelt T150, millet or barley flours. And to remain consistent with our approach, it's not just about choosing flours from ancient grains grown with respect for the environment: we must also prioritize milling that is as traditional as possible.

Sourdough for preparing bread and baking it in a cauldron

Sourdough or yeast: what to choose?

Traditionally, only natural sourdough was used in these ancient breads. This allowed for slow, rustic fermentation, in keeping with available resources.

👉 But you can use fresh baker's yeast as a modern alternative.
This facilitates rising and reduces fermentation time, but it is no longer historically accurate!
