Cast Iron Dutch Oven: How to Bake Bread

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 be careful: baking bread in a cauldron is not the same as simmering a stew.

The Fire: Intense for Bread, Gentle for Cooking

One of the key points is fire management:

For baking bread, the cauldron's temperature must be high: between 200 and 250 °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 daily cooking (stews, broths, porridges, etc.), it's the opposite: avoid flames.
➤ Cook over 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 correctly.

1. Prepare the fire

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

You will need:

an abundant bed of embers;

more to add 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 putting in the bread. (200°/250°)

3. Protect the bottom

Before putting in the dough, line the bottom with:

untreated cabbage, vine, lemon, or chestnut leaves;

or, simpler, straw or layers of baking paper.

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

Caution: some plants are toxic!

4. Place the dough

Gently place the dough in the hot cauldron.

Then:

score if you wish;

close immediately.

It's important to lose as little heat as possible and retain moisture.

5. Arrange the embers for baking

With this suitable cauldron, do it like this:

a bed of embers underneath;

more embers on the lid.

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

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

With this model, it's better to have:

moderate heat underneath;

more generous heat on the lid.

6. Baking time

Allow generally 40 to 50 minutes.

Simple checkpoints:

at 20 minutes: check the embers;

at 25 minutes: slightly turn the cauldron if possible;

at 40 minutes: perform a first check;

up to 50 minutes if necessary.

7. How to tell if the bread is done

The bread is good if:

it has a well-formed crust;

it sounds hollow when tapped;

the bottom is brown, not black.

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 bottom of the bread from burning. The bread was dense, very lightly salted, but nourishing.

- In the Middle Ages

Cauldron-baked bread was mostly found among the less affluent or during military campaigns. A mixture of barley and wheat was frequently used. Fermentation remained slow, from a sourdough starter, but techniques became more refined. The addition of salt, which had significant market value, depended on available regions and resources – it was not systematic, and often less pronounced among the less wealthy.

- Among transhumant shepherds (1930s)

During their mountain migrations, shepherds would bake bread directly in a cast-iron cauldron over a bed of embers, using finer wheat flour and a little sourdough. It was simple bread, quickly baked over a high heat.

Where to Get Flour?

It's not easy to find whole 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 also need to prioritize as traditional a milling process as possible.

We found Moulin des Moines in Alsace: a family business that has chosen to work with organic grains using traditional methods, still employing stone mills!

Sourdough starter for preparing and baking bread in a cauldron

Sourdough or Yeast: Which 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's no longer historically accurate!

Whether you're curious about living history, a bushcraft enthusiast, or an experimental cook: cauldron bread is a simple act, but rich in history.
