Seasoning a cast iron pan is a simple process that can be done on a stove or in an oven. It involves coating the pan with a thin layer of oil and heating it until the oil bonds to the metal, creating a non-stick surface. This process can be done multiple times to create a stronger coat of seasoning that will last longer. While some people prefer to season their cast iron pans on the stove, others argue that using an oven yields more even results. However, it is important to note that cast iron pans are typically pre-seasoned by the manufacturers, so the process of seasoning may not be necessary unless the seasoning erodes over time.

The importance of thin layers of seasoning
Seasoning a cast-iron pan is important to prevent rusting and food from sticking to it. The process involves heating thin layers of fat (like oil) on the cast iron, which then bonds to the metal and to itself through polymerization. This creates a protective coating with non-stick properties.
While cast iron pans often come pre-seasoned, it is recommended to add a few more layers of seasoning before use. This process involves scrubbing the pan with warm, soapy water, drying it thoroughly, and then heating it on a stovetop flame for a few minutes to remove any lingering moisture. The pan is then coated with a thin layer of oil and placed in an oven at a temperature between 200 and 350 degrees Fahrenheit for 10 minutes. After this, the pan is removed, and any excess oil is wiped away. The oven temperature is then increased to 300-450 degrees Fahrenheit, and the pan is returned to the oven for an hour.
Additionally, in the early stages of seasoning, an uneven cooking surface is expected. Factors such as what and how you cook, hot spots on your stove, and the angle of your stove will influence how the initial coats of seasoning form. These variations in the seasoning finish typically even out with use, and the pan will continue to develop interlocking layers of seasoning with each use.

Pre-seasoning on cast iron pans
Seasoning a cast-iron pan is essential to prevent rusting and food from sticking to it. Most cast iron pans come pre-seasoned from the factory, but it is recommended to add a few more layers of seasoning. Before seasoning, wash the pan with warm soapy water, dry it thoroughly, and heat it on a stovetop flame for a few minutes to drive off any lingering moisture.
To season a cast-iron pan on a stove, heat the pan on the stove for about 5 minutes to ensure it is completely dry. Then, turn off the heat and let the pan cool down. Once the pan is cool, rub a thin layer of oil onto the interior surface. Any type of oil can be used, such as vegetable oil, grapeseed oil, flaxseed oil, lard, or canola oil. Buff out the oil with a cloth or paper towel, ensuring there is no excess oil remaining. Turn the pan upside down and place it back on the stove over low heat for about an hour. This process allows the oil to bond to the metal, creating a non-stick surface.
Some people prefer to season their cast-iron pans in the oven, as it can create a more even layer of seasoning. To do this, preheat the oven to 200-350 degrees Fahrenheit. Place the clean and dry pan upside down on the middle rack of the oven to prevent oil from pooling. Bake for about an hour, then turn off the oven and let the pan cool inside. Once the pan is cool, wipe away any excess oil and return the pan to the oven for another hour at 400 degrees Fahrenheit.
It is important to note that thin layers of seasoning are more durable than thick layers. In the early stages, an uneven cooking surface is normal, and the pan will develop interlocking layers of seasoning over time. Regular use and maintenance of a cast-iron pan will improve its performance and durability. Cooking foods with a lot of oil or fat, such as bacon or chicken, can also help build and preserve the seasoned coating.

Oiling-and-heating process
Seasoning a cast-iron pan refers to the process of creating a hard, practically non-stick surface coating on the pan. This is done by adding a layer of oil and heating it, causing the oil to structurally change and turn into a relatively non-stick surface. This process is often done in the oven, but it can also be done on the stove.
When seasoning a cast-iron pan on the stove, it is important to start with a clean and dry pan. Wash the pan with warm soapy water, dry it thoroughly, and then place it on a stovetop flame for a few minutes to drive off any lingering moisture.
Once the pan is dry, you can begin the oiling-and-heating process. Here is a step-by-step guide:
- Heat the pan on the stove for a few minutes to open the iron's pores and better absorb the seasoning.
- Remove the pan from the heat and allow it to cool slightly.
- Apply a thin layer of oil to the interior of the pan. You can use a variety of oils, such as vegetable oil, grapeseed oil, flaxseed oil, or lard.
- Use a paper towel or cloth to rub the oil into the surface of the pan, ensuring that it is evenly coated.
- Return the pan to the stove and heat it over medium heat for a few minutes.
- Continue rubbing the pan with oil as it heats up, allowing the oil to penetrate the pores of the iron.
- Once the oil starts to smoke, remove the pan from the heat and allow it to cool.
- Repeat this process a few times, adding more oil as needed, until the pan has a dark, shiny surface.
It is important to note that the oiling-and-heating process may create hot and cool spots on the pan, resulting in uneven seasoning. To avoid this, some people recommend turning the pan upside down during the heating process and placing a baking sheet or foil underneath to catch any excess oil.
By following these steps, you can effectively season a cast-iron pan on the stove, creating a non-stick surface that improves with each use. With proper care and maintenance, your cast-iron pan can last for generations.

Cleaning and maintaining a seasoned pan
A seasoned cast iron pan is easy to maintain. Here are some tips for cleaning and maintaining a seasoned pan:
Cleaning
- Before the pan cools, scrape off any remaining food into the trash using a wooden spatula or a flat metal spatula. Be careful not to scratch the seasoning.
- To remove burnt-on residue, boil some water in the pan to loosen it. Then, use a non-metallic scraper, such as a nylon scrubbing brush or a pan scraper, to remove it.
- For tough spots, scrub with kosher salt and water. You can also use a non-abrasive sponge, such as a Dobie sponge, or the soft side of a Scotch-Brite sponge.
- Allow the pan to cool before running it under hot water. The hotter the water, the easier it will be to clean. Gently wipe the pan with a soft washcloth.
- Mild dish soap can be used, but it is not necessary. Avoid using large amounts of soap, as it can strip the seasoning.
- Dry the pan promptly and thoroughly with a lint-free cloth or paper towel.
Maintaining the Seasoning
- After drying, coat the pan with a thin layer of cooking oil, such as canola oil, flaxseed oil, or avocado oil. Use a paper towel to rub the oil all over the inside and outside of the pan, including the handle.
- If you notice any rust spots, scour the rust, rinse, dry, and rub the pan with a little vegetable oil.
- To build up the seasoning, cook fatty foods in the pan, such as bacon or sausage. The fat will coat the pan with an extra layer of seasoning.
- Avoid cooking acidic foods, such as tomatoes, citrus, or vinegar, as these can strip the seasoning.
- If the pan is new, it is recommended to put it through one basic round of seasoning before use.
- To season the pan, heat it in the oven at a temperature between 200 and 500 degrees Fahrenheit for about an hour. Place the pan upside down on the top rack, with a baking sheet or aluminium foil on the rack below to catch any excess oil.
- After seasoning, let the pan cool in the oven before touching it.
