How to Season Cast Iron Cookware
If you were lucky enough to get your hands on a cast iron frying pan for Christmas this guide will tell you exactly how to season and look after it to make sure it does the job and lasts for a long time. If you haven’t got any cast iron cookware, it’s definitely worth looking out for second-hand. So long as it has no cracks or chips it will be as good as new once you clean and season it.
After having bought so many cheap pans, only for them to fall apart soon after, I’ve found cast iron so much more durable. They also distribute the heat really evenly, so they’re great to cook in. The other huge plus – is no Teflon. What happens to that stuff when it starts to flake off in your dinner…?
If you find everything sticks to your cast iron pan, you’ve probably not seasoned it properly.
How to season your cast iron cookware
Seasoning (also known as curing) just means filling up all the tiny holes and craters in the surface of the iron with grease/ oil to leave a smooth continuous non-stick surface.
If your pan isn’t non-stick, is rusty or hasn’t been seasoned yet, you’ll need to start by thoroughly cleaning the cast iron pan with a hot soapy water (this is fine to do before you season it, but not after).
I used lard to season my cast iron pan, but coconut oil should work well too. Firstly rub the oil all over the pan, but just lightly. Then rub off the oil with a paper towel.
Next, put the pan upside down in the oven (make sure you have a large tray on the bottom shelf to catch any drips). The oven will need to be at about 250 C (450F) and this stage will take about half an hour. Then, take the pan out of the oven and allow it to cool. You’ll want to repeat this process 3 or 4 times.
When you cook in your pan, you’re repeating this process, since the fats in your cooking will be continuing to fill any tiny holes in the surface again.
How to Clean Cast Iron After Each Use
Once your cast iron pan is properly seasoned, cleaning it becomes incredibly easy. In fact, cleaning it correctly is essential to maintaining that beautiful non-stick surface you've created. The key is to avoid soap and never soak your pan. Instead, clean it while it is still warm using hot water and a soft cloth or non-abrasive scrubber.
If there are bits stuck to the surface, try using coarse salt as a gentle abrasive. Sprinkle salt into the pan and scrub it with a damp paper towel or clean cloth. This will lift away food without damaging the seasoning layer.
Dry your pan thoroughly after cleaning to prevent any rust from forming. You can do this by placing it back on the stove over a low flame for a minute or two until all the moisture has evaporated. Once dry, add a tiny amount of oil to the surface, wipe off the excess with a paper towel, and store it away ready for next time.
What to Avoid With Cast Iron
There are a few things that can ruin a well-seasoned pan. Acidic foods like tomatoes or vinegar can strip away the seasoning if left to simmer for too long. While short cooking times may not do much harm, it's better to use another pot for long tomato-based stews or similar dishes.
Also avoid metal scourers, harsh dishwashing detergents, and the dishwasher. These will all damage the seasoning and can lead to rust, which then requires a full re seasoning process to recover.
Storing Your Cast Iron Cookware
When your cookware is not in use, store it in a dry place. If you stack other pots or pans on top, place a paper towel between them to protect the surface. This also helps absorb any residual moisture, further protecting your pan from rust.
Some people store their cast iron with the lid slightly ajar or place a small wooden spoon inside to allow air circulation. This prevents any trapped moisture that can lead to rust or a metallic smell.
Rescuing a Rusty Pan
If your cast iron has been neglected and shows signs of rust, don't panic. It can usually be saved with a bit of elbow grease. Start by scrubbing off the rust using steel wool or a metal brush until you reach clean, bare metal. Then, follow the same seasoning steps listed earlier to restore it to a non-stick finish.
In extreme cases, you can even use a self-cleaning oven cycle to strip everything off the pan. Just be aware that this method can be harsh and may not be recommended for all types of cast iron cookware. Always research your specific item if you're unsure.
Cooking Tips for Cast Iron
Because cast iron retains heat so well, it's perfect for searing meat, sautéing vegetables, and baking cornbread or frittatas. Heat it slowly to avoid cracking and always preheat before adding food to prevent sticking.
Try to use a bit more fat or oil the first few times you cook, especially if you've just seasoned the pan. As it builds up more layers, it will become increasingly non-stick, even for eggs or fish.
One often-overlooked benefit of cooking with cast iron is the small amount of iron that leaches into your food, which can be helpful if you're prone to low iron levels. It’s a simple, natural way to support your health without pills or supplements.
Why Cast Iron is Perfect for Paleo Cooking
For those following a Paleo lifestyle, cast iron is one of the best choices for cookware. Unlike modern non-stick pans, it contains no harmful chemicals or coatings that can leach into your food. It allows you to cook over high heat and develop incredible flavours and textures that align with ancestral cooking methods.
Whether you’re browning grass-fed steak, roasting sweet potato wedges, or preparing a hearty one-pan breakfast, cast iron is up to the task. It’s versatile, rugged, and once you’ve broken it in, incredibly easy to cook with.
Second-hand Cast Iron: A Hidden Treasure
If you're hunting for cast iron, don't overlook garage sales, op shops, or online marketplaces. Many older pans, especially those made decades ago, are of superior quality to newer models. Brands like Griswold and Wagner are especially sought after for their craftsmanship and smooth cooking surfaces.
Even if a second-hand pan looks terrible, as long as it isn’t cracked, it can often be restored to near-new condition. Cleaning, seasoning, and a little patience can turn a rusty old find into your new kitchen favourite.
The Long-Term Payoff
With proper care, your cast iron pan can last a lifetime — or longer. Many families pass down cast iron cookware through generations. Each time you use it, you build on its history and improve its cooking surface. Unlike disposable non-stick pans, it gets better with age.
So whether you're a seasoned Paleo chef or just getting started, investing time into maintaining your cast iron is well worth it. It’s more than just a pan — it’s a link to traditional cooking methods, a healthier choice for your family, and a reminder that the best things in the kitchen don’t come with a non-stick coating.
