How to Season a New Potjie Pot: Step-by-Step South African Guide
Quick Answer: Season a new potjie pot by: (1) washing with soapy water and drying completely, (2) heating it over fire until very hot, (3) rubbing the interior generously with cooking oil while still hot, (4) allowing to cool, then repeating 2–3 times. This builds a non-stick carbon layer that protects the cast iron and improves with every cook.
A new bare cast iron potjie pot comes with a factory protective coating that must be removed before first use. Once that is cleaned off, the pot needs to be "seasoned" — a process of baking oil into the iron to create a natural non-stick layer and seal the metal against rust. Done correctly, your potjie pot will perform better with every use and last a lifetime.
What You Will Need
- Dish soap and a stiff brush or scour pad (one-time use before first seasoning only)
- Cooking oil with a high smoke point: sunflower, canola, coconut, or lard. Avoid olive oil — it has a low smoke point and turns rancid.
- Old rags or paper towels (they will turn black)
- A lit braai fire or gas hob
- Oven mitts or braai gloves — the pot will get extremely hot
Step-by-Step Potjie Pot Seasoning Guide
Step 1: First Wash (One Time Only)
New cast iron pots arrive with a factory rust-prevention coating. Wash the pot with warm water and dish soap using a stiff brush. This is the only time you should use soap on your potjie pot — after this, soap is not recommended as it can strip the seasoning you build. Rinse thoroughly.
Step 2: Dry Completely
Dry the pot with a clean cloth. Then place it over a low fire for 5– 10 minutes to drive off any remaining moisture. Cast iron left damp will begin to rust within hours. The pot must be bone dry before seasoning.
Step 3: Heat Until Very Hot
Place the pot over a medium-to-high fire (coals or gas). Heat until the interior is very hot — you should see a slight shimmer of heat coming off the metal. This opens the iron's pores slightly, allowing the oil to penetrate.
Step 4: Apply Oil
Using a rag or crumpled paper towel held with braai tongs, rub a generous coating of cooking oil over the entire interior surface of the hot pot — the sides, the bottom, and the interior of the lid if it has one. Work quickly and apply a thick, even coat.
Step 5: Burn Off Excess Oil
Leave the oiled pot over the fire for 15–20 minutes. The oil will smoke and the inside will darken. This is normal — the oil is polymerising (hardening) and bonding to the iron surface. The pot will turn from grey to a dark brown or black inside.
Step 6: Cool and Repeat
Remove the pot from the heat and allow it to cool completely. Once cool, repeat Steps 3–5 at least two more times (three seasoning cycles total). Each round builds a thicker, harder layer.
Step 7: First Cook — Season in Use
For your first potjiekos, cook something fatty and robust: lamb, pork, or oxtail. Avoid very acidic foods (tomatoes in large quantities) for the first few cooks, as acid breaks down a new seasoning layer. After 3–5 uses, the seasoning will be well established and nearly indestructible.
Maintaining the Seasoning After Each Use
| After Cooking | Do This |
|---|---|
| Cleaning | Rinse with hot water while pot is still warm. Use a stiff brush or chainmail scrubber — no soap. For stubborn residue, add water and simmer for 5 minutes over low heat. |
| Drying | Dry completely — either with a cloth and then briefly over heat, or leave over low coals for 10 minutes after cleaning. |
| Storage oiling | While still warm, rub a very thin coat of oil over the interior. Wipe away any excess. This prevents rust between uses. |
| Storage position | Store in a dry place. If possible, place a paper towel inside to absorb any moisture. Store with the lid off or ajar. |
Rust: What to Do
If rust spots appear (typically from leaving the pot wet or storing in a damp place), do not panic. Bare cast iron is fully restorable:
- Scrub rust spots with steel wool or coarse salt and oil until the rust is removed
- Wash with soapy water (only time you use soap in this process)
- Dry completely over heat
- Re-season from Step 3 above — three cycles minimum
A rusted cast iron pot is not ruined — it simply needs to be re-seasoned.
Frequently Asked Questions
How many times must I season a new potjie pot before first use?
At minimum three full seasoning cycles. More is better. Some South African braai enthusiasts do five rounds before the first real cook. The more you season before cooking, the better the natural non-stick performance.
What oil is best for seasoning a potjie pot?
High smoke point oils work best: sunflower oil, canola oil, coconut oil, or rendered lard. Avoid olive oil (low smoke point, turns rancid) and butter (milk solids burn and go rancid).
Can I season a potjie pot in the oven instead of over a fire?
Yes. Place the oiled pot upside down in an oven at 200–220°C for one hour. Put a baking tray on the shelf below to catch oil drips. Allow to cool in the oven. This works well for smaller potjie pots.
My potjie pot is still rusty after washing. Is it ruined?
No. Cast iron cannot be permanently ruined by surface rust. Scrub with steel wool until rust is removed, re-wash, re-dry, and re-season. Even severely rusted pots can be fully restored with electrolysis or aggressive mechanical scrubbing.
Should I season the outside of the potjie pot too?
The exterior of a traditional 3-leg potjie pot is constantly exposed to fire and will self-season over time. You may apply a light oil coating to the outside during seasoning, but it is the interior that matters most for cooking performance and rust prevention.
