The Upside-Down Seasoning Secret: Why Cast Iron Pans Need A Flip

Seasoning a cast iron pan is a process that involves baking a layer of carbonized oil onto the pan's surface. This protective layer gives the pan a natural, easy-release finish and prevents rusting. To achieve this, the pan is rubbed with a thin layer of oil and heated in an oven at a high temperature, typically between 350 to 500 degrees Fahrenheit. Placing the pan upside down during this process has several benefits. Firstly, it prevents oil from pooling on the cooking surface, which can lead to sticky spots. Secondly, it allows gravity to pull any excess oil out of the pan, resulting in a more even coating. By seasoning a cast iron pan upside down, one can ensure a smoother and more effective non-stick coating.

To prevent oil pooling and drips

Seasoning a cast iron pan is a process that involves baking a layer of carbonized oil onto the pan to form a protective coating. This coating gives the pan an easy-release finish, making it easier to cook and clean. It also helps to prevent the pan from rusting.

It is important to use only a thin layer of oil when seasoning a cast iron pan. This is because too much oil can cause the pan to become sticky. After applying the oil, the pan should be buffed so thoroughly that it no longer looks greasy. Even a small amount of excess oil can pool during seasoning, forming hardened droplets on the cooking surface.

By placing the pan upside down in the oven and using only a thin layer of oil, you can help ensure that the oil does not pool or drip, resulting in a smoother and more effective seasoning.

To ensure even heating

Seasoning a cast-iron pan is essential for ensuring even heating and creating a protective coating that prevents sticking and rusting. The process involves heating thin layers of fat, such as oil, on the cast iron, which then bond to the metal through polymerization. This forms a hard, blackened skin that protects the metal and creates a non-stick surface.

When seasoning a cast-iron pan, it is crucial to start with a clean surface. Use warm, soapy water to scrub the pan thoroughly, and then dry it completely. Apply a thin, even layer of cooking oil to the pan's interior and exterior, including the handle. Place the pan upside down on a baking sheet or aluminium foil in the oven and bake at a temperature between 450-500 degrees Fahrenheit for about an hour. Allow the pan to cool completely before handling.

By seasoning your cast-iron pan upside down, you ensure even heating and prevent pooling, resulting in a consistent and effective seasoning layer.

To avoid sticky spots

A cast-iron pan can become sticky due to a build-up of oil on its surface. This can be caused by using too much oil or the wrong type of oil when seasoning the pan. To avoid this, it is important to use a thin layer of oil when seasoning. Oils such as vegetable, grapeseed, canola, sunflower, or other oils with a high smoke point are recommended.

Another reason for stickiness is not heating the pan thoroughly before cooking. Cooking on a cold skillet with cold oil will cause sticky residue to form. To avoid this, make sure the pan is heated up before adding any food.

If your cast-iron pan does become sticky, there are a few fixes you can try. Firstly, try washing the pan with hot, soapy water and drying it. If it's still sticky, the pan may be overseasoned. In this case, place the pan upside down on the top rack of the oven at 450-500 degrees Fahrenheit for about an hour. This will allow the excess oil to drip off. You may need to repeat this process a few times until the stickiness is gone.

For super stubborn spots, you may need to scour the pan and re-season it. This involves using a steel pad or salt to remove the initial layer of seasoning, drying the pan on the stovetop, and then re-oiling and seasoning it again.

It's important to note that the oven temperature and baking time are also crucial factors in the seasoning process. If the oven temperature is too low or the baking time is too short, the oil may not polymerize properly, resulting in a sticky pan.

To prevent rusting

Cast iron pans are susceptible to rust when exposed to moisture for extended periods of time. This can happen when the pan is left to soak in the sink, put in the dishwasher, or allowed to air dry. To prevent rusting, it is important to dry your cast iron pan thoroughly after washing it. Use a paper towel or a lint-free cloth to ensure the pan is completely dry, and consider placing it on the stovetop on low heat for a few minutes to eliminate any remaining moisture.

Once your cast iron pan is dry, the next step in preventing rust is to apply a light layer of cooking oil, such as vegetable oil or grapeseed oil, to the entire surface, including the bottom and handle. This protective layer of oil, known as seasoning, helps to create a non-stick surface and can also give the pan a signature dark matte finish.

To season your cast iron pan, start by preheating your oven to between 450 and 500 degrees Fahrenheit. Place a sheet of aluminum foil or a foil-lined baking sheet on the bottom rack of the oven to catch any oil drips. Then, apply a thin, even layer of cooking oil to the entire surface of the pan, inside and out. Wipe away any excess oil, ensuring there is just a thin layer that does not drip or run when the pan is tilted.

Place the cast iron pan upside down on the top rack of the oven and bake it for about an hour. Turn off the heat and allow the pan to cool in the oven. This cooling period helps the seasoning to further cure and adhere to the iron.

By following these steps to properly season your cast iron pan, you can create a protective layer that guards against future rust. Additionally, always ensure your cast iron pan is completely dry before putting it away, and store it in a low-humidity environment to prevent moisture buildup, which can lead to rusting.

To create a non-stick coating

Seasoning a cast iron pan creates a non-stick coating, also known as a protective coating, on the cookware. This is done by heating thin layers of fat (like oil) on the cast iron. As the fat is heated, it bonds to the metal and to itself in a process called polymerization, with the fat converting into a form of plastic.

To create this non-stick coating, you must first wash and dry your pan. Give the pan a good scrub with warm, soapy water, then dry it thoroughly. You can then put the pan on a stovetop flame for a minute or two to drive off any lingering water. Next, rub the pan all over, inside and out—including the handle—with cooking oil. You can use vegetable, canola, corn oil, lard, tallow, or coconut oil. You want to rub the oil all over, but then buff it so thoroughly that the pan no longer looks greasy. Even a small amount of excess oil can pool during seasoning, forming hardened droplets on your cooking surface, or turn sticky if left unused for a few days.

After this, place the oiled pan in a preheated oven at 450°F (230°C) for 30 minutes. It may get smoky, so keep your kitchen well-ventilated. During this time, the oil will polymerize and form the first of several hard, plastic-like coatings. Using the oven provides an even heat that will more effectively set the oil all over the pan, whereas stovetop burners will produce hot and cool spots, which can lead to uneven initial seasoning.

While it's not essential, you can place the pan upside down and put a baking sheet or piece of foil underneath to catch any excess oil that runs and pools, as gravity will pull it out of the pan.

Once the half hour is up, take the pan out and rub it once more all over with oil, buffing it out as before. Then put it back in the oven for another 30 minutes. You'll want to do this oiling-and-heating process three to four times to set down a good initial layer of seasoning. Once you're done, let the pan cool down and it's ready for cooking.
