When one thinks of cooking over a wood fire, the image that often comes to mind is grilling directly over the embers. However, after more than ten years of practicing bushcraft, bivouacking, and outdoor cooking, we have been delighted to discover the extensive possibilities that cauldron cooking can offer.

The limitations of the grill: little diversity and burnt fats
Grilling over a fire has undeniable charm… but it has several major drawbacks:
- You are limited to dry cooking: meat, fish, vegetables, and you have to prepare side dishes in advance, which will often be reheated in a simple aluminum mess tin. This significantly limits the diversity of cooked dishes.
- It's impossible to bake bread, so you have to settle for eating it softened, after being carried for hours in a backpack.
- Animal fats drip 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.
With a good cauldron, you can:
- Prepare countless recipes: soups, stews, broths, simmered dishes…
- Bake bread and even cakes.
- Avoid burnt fats and carcinogenic substances.
It's a true return to ancestral, rustic, yet incredibly rich and creative cooking.

Cast iron, iron, or copper: which material for a cauldron?
The cauldron's material plays a decisive role in cooking quality. Here's a technical comparison based on our experience:
- Cast iron:
Excellent heat distribution
High thermal inertia: it stores heat and releases it slowly and evenly
Ideal for long, slow-cooked dishes
Very resistant to wood fires and intensive use
Can last for decades if well maintained (seasoning)
- Iron:
Light but heats up too quickly, cools down quickly
Less homogeneous: risk of local burning
Very susceptible to corrosion
- Copper:
Excellent heat conductivity, but also cools down very quickly. It reacts to acidic foods (tomato, vinegar), and often requires a tin lining to prevent copper migration into food.
Too fragile for direct cooking in embers.
Expensive and not well suited for bushcraft
👉 Verdict: cast iron is the best material for cauldron cooking in nature.
👉 Important: Demand cast iron that complies with European food contact standards!

What cauldron volume to choose?
The cauldron's volume is crucial depending on its use. We have tested different sizes, and here's what we learned:
- 6 liters:
Allows cooking a complete meal for 2 to 4 people (stew, soup, and even bread)
Wide enough to stir well, without overflowing.
Not too heavy, transportable even for bivouacking.
Compatible with small, discreet fires.
- Less than 4 liters:
Too small for simmering or cooking for 2-3 people
Boils quickly, temperature difficult to stabilize, and the small volume doesn't allow for all recipes.
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, one question often arises: with or without legs? Here's our feedback:
- Cauldron without legs:
Requires a tripod and a suspended chain.
More complicated to stabilize, especially on uneven terrain.
Longer, more cumbersome installation.
More suitable for a semi-permanent setup (campsite, garden)
- Cauldron with 3 legs:
Maximum stability: rests directly in 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, a 3-legged cauldron is a clear choice.

Maintenance tips for a cast iron cauldron
A well-maintained cast iron cauldron can last a lifetime—and even be passed down through generations. Here's our method for preserving its cooking qualities and extending its lifespan.
1. Rinse with lukewarm water
After use, let the cauldron cool, then rinse it with lukewarm water. Avoid thermal shocks (ice-cold water on hot cast iron) which could cause micro-cracks.
2. Little to no soap
A cast iron cauldron has seasoning that improves with each use—a thin protective layer formed from polymerized cooking oils. Too aggressive soap can damage it, so limit yourself to cleaning with a firm natural fiber brush to remove residues.
3. Wipe thoroughly
After rinsing, wipe it immediately with a clean cloth or dry towel. Moisture is cast iron's #1 enemy: it promotes rust.
4. Oil protection
Once dry, apply a thin layer 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 preventing corrosion. Light oiling after each outing is also the best way to maintain 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 cleaning and oiling our cast iron cauldrons.
The kit contains:
-
A firm, brown brush, 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 format is ideal for beginners. It allows cooking for 2 to 4 people, remains transportable for bivouacking, and is suitable for all recipes, including bread.
Is a cauldron with or without legs better?
With three legs for outdoor use. It sits directly on the embers without a tripod or complex setup—it's the most stable and practical solution for cooking over a wood fire.
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 quickly, and copper is too fragile for direct cooking in embers.
What standard should I check before buying a cast iron cauldron?
Demand cast iron that complies with European food contact standards. This guarantees that the metal does not migrate into the food during cooking.
