Cast-iron pans are durable, affordable, and perfect for a variety of cooking techniques. They are also versatile, allowing you to sear, fry, bake, roast, braise, and more. However, they do require some care and maintenance to keep them in good condition. One of the most important things you can do to maintain your cast-iron pan is to season it correctly. Seasoning creates a protective layer of carbonized oil on the pan's surface, which makes it more durable, improves heat distribution, and prevents food from sticking. This protective layer increases with every use, so it's essential to build up a good layer of seasoning before using your pan for the first time and to maintain it properly through regular use and occasional re-seasoning.
How to Cure Cast-Iron Pans
| Characteristics | Values |
|---|---|
| Purpose of seasoning | To create a protective layer of oil baked into the pan's surface, making it durable, preventing rust, and improving heat distribution |
| Frequency | Seasoning is recommended maintenance two or three times a year |
| Oil type | Neutral oils such as canola, vegetable, or flaxseed oil are recommended. Other options include olive oil, coconut oil, or melted shortening. |
| Application method | Use a paper towel, cloth, or brush to apply a thin layer of oil to the pan, ensuring all surfaces are coated. Wipe away excess oil, leaving a very thin coat. |
| Oven temperature | Preheat the oven to 350°F-500°F (150°C-260°C). |

How to season a cast iron pan
Seasoning a cast iron pan is a simple process that will ensure your cookware lasts for generations. Seasoning refers to the hard, practically nonstick surface coating your cast iron pan. Most cast iron skillets come pre-seasoned, but over time, the seasoning erodes, and you will need to re-apply it.
Firstly, clean the skillet with a stiff brush or plastic scrubber and warm, soapy water. If your pan is rusty, use a mixture of salt and oil and scrub hard into the rust, then rinse thoroughly in hot water. Use steel wool if necessary. If your pan is new, scouring is also a good idea to get off any wax or protective oil.
Once your pan is clean, dry it thoroughly. Then, using a paper towel or an old towel, coat the pan with a neutral oil like canola, vegetable oil, or flaxseed oil. This includes the bottom, sides, and handle of the pan. Wipe away all excess oil so no pooling oil is visible — the oil should just coat the metal. The pan should feel practically dry to the touch.
Place the pan upside down in the oven and bake at 350°F (177°C) for 1 hour. You can also place the pan in the oven at 450°F (232°C) for 30 minutes. Line the rack below with foil to catch any oil drips. This will protect the surface and give it an almost nonstick quality.
Turn off the oven and let the pan cool in the oven before touching. If you are starting seasoning from scratch, repeat these steps multiple times until a smooth finish develops. A well-seasoned cast iron skillet is a well-used one. Each time you cook with some type of fat, you will be laying down more seasoning.

How to remove rust from a cast iron pan
Cast iron is a durable and versatile material that can be used for various cooking techniques, such as searing, frying, baking, roasting, and braising. While it is a highly reactive material that can rust quickly, proper care and maintenance can extend the lifespan of cast iron cookware for generations.
To remove rust from a cast iron pan, you can try the following methods:
Scrub and Re-Oil
Use a steel wool scrubber or a stiff-bristled brush to scrub away the rust. You can also use dish detergent if needed. Be sure to scrub gently to avoid removing the carbonized oil that seasons the pan and keeps it non-stick. After scrubbing, dry the pan completely using a lint-free cloth to prevent new rust from forming. Re-season the pan immediately after cleaning.
Potato and Coarse Sea Salt
Sprinkle coarse sea salt generously over the rusty areas of the pan. Cut a potato in half and use the cut side to scrub the cast iron in small circular motions until the rust lifts off. Rinse and dry the pan thoroughly after removing the rust.
Baking Soda and Dish Soap
Sprinkle baking soda generously over the rusty parts of the pan. Use a scrubber or brush to remove the rust. Rinse and dry the pan completely.
Vinegar Bath
Soak the pan in a mixture of vinegar and water to remove old seasoning and expose bare metal. After soaking, heat-dry the pan on the stove and wipe it down with a paper towel dipped in grapeseed oil.
Once the rust has been removed, it is important to re-season the cast iron pan to prevent future rusting and create a non-stick surface. To season the pan, use a paper towel to coat it with a thin layer of neutral oil, such as canola, vegetable, or grapeseed oil. Be sure to wipe away any excess oil, so the pan feels dry to the touch. Then, bake the pan upside down in the oven at 350 degrees Fahrenheit for one hour. This process will protect the surface and create a non-stick finish.

How to clean a cast iron pan
Cast-iron skillets are durable, affordable, and perfect for a variety of cooking techniques. They are also quite easy to clean and maintain. Here is a step-by-step guide on how to clean and care for your cast iron pan:
Cleaning
Firstly, always clean your cast iron pan immediately after use. It is important that the pan is still warm when you start cleaning it. Use protective gloves if the pan is too hot to handle. Do not soak the pan or leave it in water, as this can create rust. Instead, use a stiff brush or plastic scrubber under running water to clean the pan. For baked-on stains, kosher salt can be used as a scrubbing agent. If there are stubborn food particles or residue, add coarse kosher salt to some water and gently scrub with a sponge to release them.
It is also okay to use a small amount of soap on the skillet to scrub off cooked-on messes. Modern dish soaps no longer contain lye and other ingredients that can strip the seasoning, so they are safe to use. After cleaning, always dry the pan entirely with a towel or place it over low heat to evaporate any remaining water.
Seasoning
Seasoning your cast iron pan is essential to creating a protective layer that prevents rust and makes the pan more durable and non-stick. Seasoning is simply a layer of carbonized oil baked into the cookware's surface. To season your pan, start by coating the entire pan, including the bottom and handle, with a thin layer of neutral oil such as vegetable oil, canola oil, or flaxseed oil. Use a paper towel or an old cloth to apply the oil, wiping away any excess. The pan should feel practically dry to the touch.
Next, place the pan upside down in the oven and bake at 350 degrees Fahrenheit for about an hour. This process will protect the surface and give it a non-stick quality. After baking, turn off the oven and let the pan cool down completely inside. Repeat this seasoning process multiple times to develop a smooth finish. Once you have a good layer of seasoning, you can use your cast iron pan for acidic foods without worry.
Remember, the best way to maintain the seasoning on your pan is to use it regularly. Each time you cook with some type of fat, you will be adding to the seasoning. So, get cooking and enjoy the benefits of your well-seasoned cast iron pan!

Best oils to season a cast iron pan
Seasoning a cast-iron pan is a simple process that can greatly improve its performance and durability. Seasoning refers to the process of creating a hard, non-stick surface on your cast iron pan by coating it with oil and heating it until the oil bonds to the metal. This layer of carbonized oil gets better with every use and makes your pan more resistant to rust and corrosion.
When it comes to choosing the best oil for seasoning a cast-iron pan, there are several options available, each with its own unique benefits. Here are some of the most popular oils used for seasoning cast iron pans:
Grapeseed Oil
Grapeseed oil is a popular choice for seasoning cast iron pans due to its high smoke point, making it less likely to burn during the seasoning process. It is also versatile, affordable, and widely available in grocery stores. Grapeseed oil produces a smooth and non-stick surface, making it a favourite among cast iron enthusiasts.
Vegetable Oil
Vegetable oil is a blend of various oils, typically including sunflower, corn, soy, and safflower. It is a common recommendation for seasoning cast iron pans due to its availability, affordability, and effectiveness. It has a high smoke point, making it suitable for baking at higher temperatures without burning.
Canola Oil
Canola oil is another popular option for seasoning cast iron pans. It is often used interchangeably with vegetable oil, as they produce similar results. Canola oil has a high smoke point and is widely available, making it a convenient and effective choice for seasoning.
Flaxseed Oil
Flaxseed oil has gained popularity as a seasoning oil due to its ability to quickly polymerize into a layer of seasoning. However, it has a very low smoke point of 225 degrees Fahrenheit, so it requires careful temperature control during the seasoning process.
Other Options
Other oils and fats can also be used for seasoning cast iron pans, including olive oil, sunflower oil, coconut oil, lard, and animal fats like bacon grease. While these options may not be as effective as the previously mentioned oils, they can still contribute to the seasoning of your pan over time.
Remember, the key to successful seasoning is to apply thin coats of oil and repeat the process multiple times to build up a smooth and durable finish. By taking care of your cast iron pan and seasoning it regularly, you'll be rewarded with a lifetime of delicious meals.
