I really enjoy using my cast iron pan, but like many people, I sometimes don’t take the best care of it. Cast iron cookware is known for being tough and holding heat well. But they work best when they’re looked after properly, as neglect and poor care can lead to rust and loss of the non-stick surface.

That’s where seasoning comes in. All cast iron pans need proper seasoning.  It’s good practice to season your pan after cooking something that requires a thorough cleaning or after you’ve revived a rusty cast iron pan.

Seasoning cast iron may seem a bit more involved than caring for other types of pots and pans, but it’s actually quite easy to do. Let me guide you through a simple and effective way to reseason your cast iron pan each time you need to.

Why reseason your cast iron?

Cast iron cookware has been a kitchen essential for generations, possibly even a favorite in your grandmother’s collection. Its unique ability to distribute and hold heat evenly makes it a versatile option for cooking a variety of dishes. However, as time goes by, cast iron can develop rust and lose its non-stick surface, which affects its performance in the kitchen. This is where reseasoning and restoring come into play.

When you reseason and restore your cast iron, you’re giving it a fresh start by creating a new non-stick surface and protecting against rust. This process involves addressing any existing rust, thoroughly cleaning the cast iron, and applying a layer of oil or fat to create a protective barrier. The result is an improved performance from your cast iron and a longer lifespan for this essential kitchen tool.

Guide to Seasoning Your Cast Iron

Supplies Needed

• Cast iron grill pan or cast-iron skillet – this is the one I have: Lodge Cast Iron Square Grill Pan.
• Paper towel
• Cooking oil – Choose oil with a high smoke point, such as vegetable, canola, or flaxseed oil.
• Oven
• Oven mitts

Step 1: Clean it

Before you season your cast iron, you will need to clean it. You can clean it with a scrub brush or sponge. If it has rust, follow this step-by-step guide on cleaning and removing rust from the cast iron pan.

Step 2: Oil it down

Make sure the cast iron pan is completely dry, and then apply a thin layer of oil. You can use your preferred cooking oil here, including vegetable, canola, olive, or flaxseed. Use a dry paper towel and apply it all over the pan, including the sides, handle, and bottom. 

Try not to add excess oil during the seasoning process. Applying too much oil can result in a sticky or gummy surface. Always use a thin and even layer to ensure proper seasoning.

Step 3: Preheat your oven 

Preheat the oven to 400°F. This is the minimum required temperature to season the cast iron pan properly.

Step 4: Heat the cast iron pan

Place the cast iron pan in the oven and heat it for about one hour. Place it on the bottom rack of the oven. This will allow the oil to create a protective layer.

Step 5: Let the cast iron cool

Remove it from the oven with an oven mitt and place it on the stove or trivet. Allow the cast iron pan to cool. Once it is cool, it is ready to be used again. You’ll notice that it has a shiny, non-stick surface that is perfect for cooking.

Tips for maintaining your seasoned cast iron

• Do not use a dishwasher. Cast iron grills are not technically dishwasher safe. A Dishwasher will break down the seasoning and soak it for a long time. Instead, wash it by hand in a sink and wipe it clean after use with a paper towel.
• Do not keep it in the sink immersed in water. Keeping it immersed in water will guarantee rust and removal of the seasoning.
• Do not let it air dry. Dry it thoroughly after each clean with a paper towel.
• Keep it seasoned – Apply a protective layer of oil after each clean to create a protective barrier.
• Try to put a paper towel between the pan and anything you place it on in the kitchen cabinets.
• Store in a dry place – Keeping the cast iron dry will prevent rusting.
• If the cast iron skillet comes with a lid, do not store it with the lid on. The lid can trap moisture from the air between the lid and the pan, resulting in rust.
• Avoid cooking acidic goods if your cast iron pan has not been fully seasoned.

What is the best oil to season a cast iron skillet?

There are various oils that can be used for the purpose of reseasoning. The choice of oil or fat depends on personal preference and the desired outcome. 

Avoid oils with low smoke points, as they can break down and become sticky at high temperatures. 

How often should I reseason my cast iron pan?

It’s recommended to reseason your cast iron skillet after each intense clean or whenever you notice the non-stick surface deteriorating.

Can I use soap to clean my cast iron skillet?

While it’s best to avoid using soap when cleaning cast iron, a small amount of mild dish soap can be used if necessary. Just make sure to rinse it thoroughly and dry it completely afterward.

Can I use my reseasoned cast iron skillet on an induction cooktop?

Yes, cast iron is compatible with induction cooktops. Just make sure the bottom of your skillet is flat and smooth to ensure proper contact with the cooktop.

What if my cast iron skillet develops rust after reseasoning?

If your cast iron skillet develops rust after reseasoning, it’s likely due to improper drying or storage. Simply remove the rust with a proper clean, reseason the skillet, and ensure it is completely dry before storing.

How do you clean it after each use?

Contrary to your beliefs, once you have restored the pan, try not to reach for the dish soap to clean it immediately. Instead, the easy way to clean it is to rub the pan with coarse kosher salt to remove cooking debris and food particles. Use a non-scratch scouring pad or grill brush to fit and scrub between the grates with hot water.

You can certainly use mild soap for tougher jobs, but sparingly. Then, use a paper towel or clean cloth to dry it thoroughly, and then add a little oil to maintain the seasoning.
