Cast iron and campfire were made for each other. But if you've ever ended up with sticky, flaking, or rusty cookware after a trip, chances are the seasoning wasn't right for open-fire conditions. Campfire cooking runs hotter and drier than a kitchen stovetop — and your seasoning process needs to account for that.
At Browns Outpost, we build cookware for real outdoor use. Here's exactly how to season cast iron the right way for fireside cooking.
What Is Seasoning — and Why Does It Matter?
Seasoning is the layer of polymerized oil baked into the surface of cast iron. It creates a natural non-stick coating, protects against rust, and improves with every use. For campfire cooking specifically, a well-built seasoning layer is your first line of defence against the intense, uneven heat of an open flame.
What You'll Need
- Your cast iron pan, skillet, or Dutch oven
- A high smoke-point oil (flaxseed, grapeseed, or refined coconut oil)
- A lint-free cloth or paper towel
- A campfire or outdoor grill with a grate (or your home oven for the initial season)
Step-by-Step: How to Season Cast Iron for Campfire Use
Step 1 — Start with a clean surface
If your cookware is new, wash it once with mild soap and warm water, then dry it completely. If it's used, strip any rust or old flaking seasoning with steel wool, then wash and dry.
Step 2 — Apply a thin, even coat of oil
Less is more. Apply a very thin layer of oil to every surface — inside, outside, and the handle. Wipe off any excess. Too much oil leads to a sticky, gummy finish.
Step 3 — Heat it until it smokes
For initial seasoning, use your home oven at 230°C (450°F) for one hour, upside down on the middle rack with foil below to catch drips. Repeat 3–4 times for a solid base layer before taking it into the field.
Step 4 — Maintain it at camp
After each campfire use, while the pan is still warm (not scorching), wipe it out with a dry cloth. Apply a thin coat of oil before storing. Avoid soaking in water or leaving it wet overnight.
Step 5 — Re-season after hard use
High heat, acidic foods (tomatoes, citrus), or extended trips will wear down seasoning faster. If food starts sticking or you see dull grey patches, it's time to re-season. Strip, clean, and repeat the process.
Campfire-Specific Tips
- Avoid thermal shock — don't pour cold water into a screaming-hot pan. Let it cool gradually.
- Use hardwood coals, not direct flame — cooking over coals gives more even heat and is gentler on seasoning.
- Bring a small tin of oil — a quick wipe-down at camp keeps your seasoning intact trip after trip.
- Cast iron from Browns Outpost is pre-seasoned — but we always recommend building additional layers before your first fire.
The Bottom Line
Seasoning cast iron for campfire use isn't complicated — it just requires the right technique and a bit of consistency. Do it right once, maintain it on the trail, and your cookware will outlast everything else in your kit.
