When one thinks of wood-fired cooking, the image that often comes to mind is grilling directly over the embers. However, after more than ten years of practicing bushcraft, bivouacking, and cooking in the great outdoors, we have had the pleasure of discovering the breadth of possibilities that cauldron cooking can offer.

The limitations of the grill: limited diversity and burnt fats
Cooking over a fire has an undeniable charm… but it has several major drawbacks:
- We are limited to dry cooking: meat, fish, vegetables, and side dishes must be prepared in advance and are often reheated in a simple aluminum pot. This significantly limits the diversity of cooked dishes.
- It is impossible to bake bread, so you have to resign yourself to eating it soft, after it has been hauled around for hours in a backpack.
- Animal fats fall onto the embers, producing smoke containing potentially carcinogenic substances.
The cauldron: more varied and healthier cooking
The cauldron brings real diversity and a touch of originality to wood-fired cooking by offering a healthy alternative to grilling.
Cast iron is a very healthy material when raw, without dubious interior enamel or non-stick coatings containing PFAS.
👉 Important: demand cast iron that complies with European Regulation (EC) No 1935/2004, applicable to materials intended for food contact.
With a good cauldron, you can:
- Create countless recipes: soups, stews, porridges, simmered dishes…
- Bake bread and even cakes.
- Avoid burnt fats and carcinogenic substances.
It is a true return to an ancestral, rustic, yet incredibly rich and creative way of cooking.

Cast iron, iron, or copper: which material for a cauldron?
The material of the cauldron plays a decisive role in the quality of the cooking. Here is a technical comparison based on our experience:
- Cast iron:
Excellent heat distribution
Great thermal inertia: it stores heat and releases it slowly and evenly
Ideal for long and slow-cooked dishes
Very resistant to wood fires and intensive use
Can last for decades if well maintained (seasoning)
- Iron:
Lightweight but heats up too fast, cools down quickly
Less uniform: risk of burning locally
Very sensitive to corrosion
- Copper:
Excellent heat conductivity, but also cools down very quickly. It is reactive to acidic foods (tomatoes, vinegar), and often requires a tin coating to prevent copper from migrating into the food.
Too fragile for direct cooking in the embers.
Expensive and poorly suited to bushcraft
👉 Verdict: cast iron is the best material for cauldron cooking in the great outdoors.
👉 Important: demand cast iron that complies with European Regulation (EC) No 1935/2004, applicable to materials intended for food contact.

What size cauldron should you choose?
The size of the cauldron is crucial depending on the intended use. We have tested different sizes, and here is our takeaway:
- 6 liters:
Allows you to cook a complete meal for 2 to 4 people (stew, soup, and even bread)
Wide enough to stir well, without spilling over.
Not too heavy, transportable even when bivouacking.
Compatible with small, discreet fires.
- Less than 4 liters:
Too small for simmering or cooking for 2-3 people
Boils quickly, temperature is difficult to stabilize, and the low volume does not allow for all recipes to be made
Not suitable for rustic and hearty dishes. Impossible to bake bread.
- More than 8 liters:
Too heavy, difficult to transport.
Requires a larger and more intense fire.
Ideal for large gatherings but not for bivouacking.
👉 The 6L is our reference size for varied, mobile, and generous cooking.
With or without legs? The detail that changes everything
When choosing a cauldron, a common question arises: with or without legs? Here is our feedback:
- Cauldron without legs:
Requires a tripod and a suspended chain.
More complicated to stabilize, especially on uneven terrain.
Installation is longer and cumbersome.
More suitable for a semi-permanent setup (campsite, garden)
- Cauldron with 3 legs:
Maximum stability: can be placed directly into the embers
No need for a tripod or suspension
Ideal for simple campfires
Better contact with the heat of the embers, especially for bread or stews
👉 For mobile bushcraft cooking, the 3-legged cauldron is an obvious choice.

Maintenance tips for a cast iron cauldron
A well-maintained cast iron cauldron can last a lifetime — and even be passed down from generation to generation. Here is our method to preserve its cooking qualities and extend its lifespan.
1. Rinsing with warm water
After use, let the cauldron cool, then rinse it with warm water. Avoid thermal shock (ice-cold water on hot cast iron) which could cause micro-cracks.
2. Little or no soap
The cast iron cauldron has a seasoning that improves itself with every use — a thin protective layer resulting from polymerized cooking oils. Overly harsh soap can alter it, so limit yourself to cleaning with a firm natural fiber brush to remove residues.
3. Dry thoroughly
After rinsing, wipe it immediately with a clean cloth or a dry towel. Moisture is the number one enemy of cast iron: it promotes the appearance of rust.
4. Oil protection
Once dry, apply a thin film of vegetable oil (coconut, rapeseed, sunflower…). Spread evenly with a suitable natural fiber brush.
This step protects the cast iron by creating a barrier against moisture, thus avoiding corrosion. A light oiling after each outing is also the best way to maintain a perfect seasoning and a natural non-stick surface. Store in a dry place.
With this simple ritual, your cast iron cauldron will remain ready for all your culinary adventures: from steaming soups in the heart of winter to summer stews shared around the fire.
Approche Libre offers a Kit of two 100% Natural fiber brushes perfectly suited for the cleaning and greasing of our cast iron cauldrons.
The kit contains:
-
A firm brush, brown in color, made of sisal and palm fibers, perfect for cleaning the cauldron without scratching the cast iron or damaging the seasoning.
- A softer brush, made of sisal fibers, ideal for spreading vegetable fat evenly, cleaning vegetables and roots, and outdoor equipment.
FAQ — Choosing your cast iron cauldron
What size cauldron should I choose to start?
The 6-liter size is ideal for beginners. It allows you to cook for 2 to 4 people, remains transportable for bivouacking, and is suitable for all recipes, including bread.
Is it better to have a cauldron with or without legs?
With three legs for outdoor use. It sits directly on the embers without a tripod or complex installation — it is the most stable and practical solution for wood-fired cooking.
Why choose cast iron over iron or copper?
Cast iron retains and distributes heat evenly for hours. It withstands intensive use and can last for decades with proper maintenance. Iron heats up too fast, and copper is too fragile for direct cooking in the embers.
How to choose quality cast iron suitable for food contact?
To make the right choice, check that the cast iron has been tested by an independent laboratory and complies with European requirements applicable to materials intended for food contact, Regulation (EC) No 1935/2004.
Our cauldrons have been laboratory tested by TÜV or SGS, two internationally recognized independent bodies in the field of product testing, inspection, and safety. The analyses specifically cover odor, taste, and the migration of numerous metals, including lead, cadmium, mercury, and arsenic. Under laboratory-tested conditions, the results comply with European requirements applicable to food contact.
These tests provide the guarantee that our cauldrons allow for healthy cooking, without the migration of undesirable substances, in compliance with European Regulation EC No 1935/2004.
Our cauldrons also comply with the REACH (EC) No 1907/2006 regulation. More than 250 substances of concern were tested in the laboratory: none were detected.
Approche Libre cauldrons have undergone these rigorous analyses to verify their compliance. You thus benefit from raw, durable cast iron adapted to the preparation of your simmered dishes.
Approche Libre therefore ensures healthy and authentic cooking.
