Before you really get started with your cast iron pan, it needs a good foundation: the patina. It forms through oil, heat, and regular use, protecting the material and making food stick less over time. That’s exactly why you should season a cast iron pan before using it for the first time.

Seasoning might sound complicated at first, but with the right preparation, it’s quite doable. What’s important is a heat-resistant oil or the right Care Conditioner, plenty of ventilation, and a bit of patience. In this guide, you’ll learn why cast iron needs to be seasoned, which oils work best, and how to season your cast iron pan step by step.

Cast iron pans don’t have an artificial non-stick coating. Instead, a natural patina develops on the surface. This protective layer forms when fat is heated strongly and bonds with the iron’s surface.

The patina serves several purposes: it protects the material from corrosion, improves frying performance, and ensures that food sticks less when used properly. The more often you use and care for your pan, the stronger this surface becomes.

Seasoning before the first use is therefore the first important step. It lays the foundation for the patina, which then continues to develop during cooking.

You should season a Wrought-Iron Pan before its first proper use. After that, you don’t need to repeat the process after every cooking session. The patina continues to develop through regular frying, cleaning, and light oiling.

Reseasoning can be useful if:

• the pan is new,
• the patina has been heavily damaged,
• rust has been removed,
• food sticks persistently,
• the pan has been thoroughly cleaned or refurbished.

In everyday use, it’s enough to gently clean the pan after cooking, dry it thoroughly, and lightly oil it or treat it with Care Conditioner.

If you want to know how to properly care for your pan after use, you’ll find the right instructions in the article Cleaning and Caring for Your Wrought-Iron Pan.

The duration depends on the heat source and the size of the pan. You should plan about 10 to 15 minutes per session. If you repeat the process two to three times, the seasoning will take correspondingly longer overall.

More important than an exact time is the visible change in the surface. During seasoning, the pan’s bottom may darken in spots or over a large area. This dark layer is the desired patina.

Always ensure good ventilation while seasoning. Heating oil or Care Conditioner can produce smoke.

For seasoning, you need a fat that can withstand high temperatures. Heat-resistant vegetable oils or fats are well suited. It’s important that the oil doesn’t burn too early and spreads evenly over the surface.

Suitable options include:

• Rapeseed oil
• Sunflower oil
• High-heat vegetable oils
• Coconut fat
• Petromax Care Conditioner for cast and forged iron

Oils with a low smoke point, like many olive oils, are less suitable. They can burn faster at high heat and leave an uneven or sticky surface.

The Petromax Care Conditioner is especially handy because it can be used both for seasoning and for later care of cast and forged iron.

Before seasoning the pan, it needs to be thoroughly cleaned. New cast iron pans may have residues on the surface due to production. These should be removed before seasoning to allow the patina to develop properly.

Here’s how to prepare the pan:

1. Clean the pan with hot water.
2. If needed, scrub it thoroughly with a brush.
3. Remove all residues completely.
4. Rinse the pan with clean water.
5. Dry it very thoroughly.
6. If necessary, warm it briefly to evaporate any remaining moisture.

Only start seasoning once the pan is completely dry. Moisture on the surface can promote rust and interfere with the seasoning process.

When seasoning, fat is heated strongly until a first protective layer forms on the surface. You can do this on the stove, on the grill, or outside over a suitable fire pit. Because of the possible smoke development, seasoning outdoors is especially pleasant.

Step 1: Clean and dry the pan

Thoroughly clean the pan with hot water and remove all residues. Then dry it completely. If you want to be sure, you can briefly place it on a warm stove plate or in a warm spot to let the last moisture evaporate.

Step 2: Apply oil or Care Conditioner

Put a small amount of heat-resistant oil or Care Conditioner into the pan and spread it thinly over the surface. The layer should be really sparing. Too much fat can become sticky or season unevenly.

Step 3: Heat the pan slowly

Heat the pan slowly at first. This allows the material to warm up more evenly. Once the pan gets hot, the fat will start to smoke. This is normal when seasoning but should always happen with good ventilation or outdoors.

Step 4: Season the surface evenly

Carefully spread the fat during seasoning with a Wooden Spatula or a heat-resistant cloth. The surface will gradually start to darken. This discoloration shows that the patina is forming.

Step 5: Let the pan cool down

Carefully remove the pan from the heat source and let it cool. Always use appropriate heat protection, as the handle and pan can become very hot.

Step 6: Remove residues

Rinse the cooled pan with hot water and gently remove any residues. Then dry the pan thoroughly again.

Step 7: Repeat the process

For a more stable base, you can repeat the seasoning process two to three times. With each round, the surface becomes darker and more resistant.

Step 8: Apply a thin layer of fat

After the last round, dry the pan completely and rub it thinly with oil or Care Conditioner. Then it’s ready for its first use.

A cast iron pan can be seasoned on the stove if it fits the cooking zone and you ensure proper ventilation. Seasoning may produce smoke. So, open windows, turn on the extractor hood, and make sure no sensitive smoke detectors are triggered.

On the stove, heat the pan slowly and increase the temperature gradually. Especially with induction, caution is wise, as the heat can build up very quickly and in a focused spot.

If you have the option, seasoning outside on the grill or over a suitable fire pit is often more pleasant.

Seasoning on the grill is especially practical because smoke and smell stay outside. Plus, the pan heats evenly when it’s securely placed on the Grilling Grate.

Here’s how to do it:

1. Clean and dry the pan.
2. Rub it thinly with oil or Care Conditioner.
3. Heat the grill.
4. Place the pan on the grill.
5. Let the fat season until the surface darkens.
6. Let the pan cool down.
7. Repeat if needed.
8. Finally, rub it thinly with fat.

Make sure to move the pan only with proper heat protection. The handle also gets very hot during seasoning.

You can also season wrought iron over an open fire. The key is a stable cooking spot and controlled heat. High flames are less suitable than steady embers because they can heat the pan unevenly in spots.

Place the pan securely and make sure it can’t tip over. Apply oil or Care Conditioner thinly and heat the pan until the surface visibly changes. Then let it cool, remove any residue, and repeat the process if needed.

When seasoning over fire, safety comes first. Use heat-resistant gloves and only move the pan when you have a secure grip.

After seasoning, your cast iron pan is ready to use. However, the patina is not fully developed at first. It continues to develop with each use and becomes more stable through regular cooking, cleaning, and light oiling.

The first dishes you cook are especially important. It’s best to choose foods that are prepared with enough fat and aren’t too delicate. Fried potatoes, bacon, sausages, or vegetables are great for building up the patina further.
