The Ultimate Guide To Priming Your Cast Iron Pan

A cast iron pan is a versatile tool that can withstand extreme heat and cook food evenly. However, it requires proper care and maintenance to keep it in good condition. One of the most important steps in caring for a cast iron pan is seasoning, which involves creating a protective layer of oil baked into the cookware's surface. This process not only makes the pan durable and prevents rusting but also enhances its non-stick properties.

Wash the skillet with warm, soapy water

When preparing to season a cast-iron pan, it is important to wash the skillet with warm, soapy water. This is because you want to ensure that there is no food residue left on the skillet before you begin the seasoning process. Using warm water and a sponge or stiff brush will help to loosen and remove any stuck-on food particles. It is recommended to use a mild dish soap that is free of harsh chemicals or abrasives. After washing the skillet, be sure to rinse it thoroughly with warm water to remove any soap residue.

Cast iron skillets are typically not washed with soap, but it is acceptable to do so when preparing to season the pan. The soap will help to remove any built-up grease or grime, ensuring a smooth surface for the seasoning to adhere to. It is important to note that if your cast iron skillet is well-seasoned, using warm water and a sponge or stiff brush may be sufficient, and soap may not be necessary.

After washing the skillet with warm, soapy water, it is crucial to dry it thoroughly. Any remaining water droplets or moisture can interfere with the seasoning process, so be sure to use clean, dry cloths or paper towels to absorb all the water. You can also place the skillet on the stove over low heat for a few minutes to ensure that any residual water molecules are evaporated. This step is important because it creates an ideal surface for the oil to adhere to in the next step of the seasoning process.

Once the skillet is completely dry, you can move on to the next step of the seasoning process, which typically involves coating the skillet with a thin layer of oil and heating it in the oven. By washing the skillet with warm, soapy water, you create a clean slate for the seasoning to be applied effectively, ensuring your cast iron skillet is protected and performs optimally during cooking.

Rinse and dry the skillet

You can also place the skillet on the stove over low heat to ensure it's completely dry. This extra step guarantees that all moisture has evaporated, reducing the risk of rusting.

After drying, it's essential to coat the skillet with a light layer of cooking oil or seasoning spray. Use a paper towel or a clean cloth to rub the oil all over the skillet's surface, including the inside, outside, and handle. This step helps maintain the seasoning and ensures your cast iron remains in good condition.

If you're using a seasoned cast iron skillet, it's crucial to dry it promptly and thoroughly after rinsing. You can use a lint-free cloth or paper towel for this step. Again, don't be concerned if you notice any black residue on the towel, as it's just the seasoning coming off.

To ensure your seasoned skillet is completely dry, you can place it over low heat on the stove or in an oven preheated to a low temperature, around 200 to 300 degrees Fahrenheit. This step ensures that any remaining moisture is eliminated, reducing the chances of rust forming.

Once your seasoned skillet is dry, apply a light layer of cooking oil or seasoning spray. Use a paper towel or clean cloth to rub the oil all over the skillet's surface, including the inside, outside, and handle. This step helps maintain the seasoning and keeps your cast iron in optimal condition.

Add a thin layer of oil to the skillet

Adding a thin layer of oil to the skillet is a crucial step in the process of seasoning a cast iron pan. Seasoning is a protective layer of oil baked into the cookware's surface to make the equipment durable, produce heat, and prevent rust.

To add a thin layer of oil to the skillet, start by pouring a small amount of vegetable oil, melted shortening, or any other oil of your choice into the skillet. A tablespoon or two is usually enough. You can also use a silicone pastry brush, a lint-free cloth, or a paper towel to spread the oil evenly. It is important to ensure that the entire skillet, including the outside and bottom, is coated thinly and evenly.

The key is to rub the oil all over the skillet and then buff it thoroughly so that the skillet no longer appears greasy. Even a small amount of excess oil can pool during seasoning, forming hardened droplets on the cooking surface or becoming sticky if left unused for a few days. Therefore, it is crucial to wipe away any excess oil with a clean cloth or paper towel. The skillet should look dry and have a dull matte finish when you are done.

By adding a thin layer of oil to the skillet and ensuring even coverage, you are preparing the pan for the next step in the seasoning process, which involves heating the pan in the oven to polymerize the oil and create a protective coating.

Place the skillet upside down in the oven

Now that you've cleaned, dried, and oiled your cast iron pan, it's time to place it in the oven. Place the skillet upside down on the middle rack of a cold oven. This will prevent any oil from pooling at the edge of the cooking surface. Place a sheet of aluminium foil on the rack below to catch any drips.

The ideal temperature for seasoning cast iron pans is between 450 and 500 degrees Fahrenheit. However, some sources suggest preheating the oven to 350 or 375 degrees Fahrenheit. Once the oven is preheated, place the pan inside and bake for about an hour. It's important to leave the oven door closed for the entire duration to maintain a constant temperature.

After an hour, turn off the heat and allow the skillet to cool completely inside the oven. Do not be tempted to open the oven door to speed up the cooling process. Once the pan is cooled down, it's ready to be used!

Bake the cast iron for about an hour

Now that your pan is clean, dry, and coated with oil, it's time to bake it in the oven. Place the pan upside down on the middle rack of the oven. This will prevent any oil from pooling at the edge of the cooking surface. Put a sheet of aluminium foil on the rack below to catch any drips.

Preheat the oven to between 350°F and 500°F. The higher the temperature, the faster the process, but be aware that this may fill your kitchen with smoke. You may want to keep your kitchen well-ventilated. Place the pan in the oven for about an hour. Do not open the oven during this time to keep the temperature constant.

After an hour, turn off the heat and let the pan cool down completely inside the oven.
