Yes, you should season cast iron skillets before using them for the first time. Seasoning is a crucial step in maintaining and developing a non-stick surface on the cast iron, preventing rust, and enhancing its cooking performance. Seasoning involves applying a thin layer of oil to the surface of the skillet and heating it to create a polymerized coating.
Here's how to season a cast iron skillet:
Clean the skillet: Wash the new cast iron skillet with hot water and a small amount of mild dish soap to remove any factory residues or protective coatings. Use a sponge or brush to scrub it gently. Avoid using harsh abrasives, as they can damage the surface.
Dry it thoroughly: Pat the skillet dry with a clean towel, and make sure it's completely dry before proceeding to the next step.
Apply oil: Coat the entire surface of the skillet, including the handle, with a thin layer of cooking oil or vegetable shortening. Common oils used for seasoning are vegetable oil, canola oil, flaxseed oil, or even lard.
Remove excess oil: Use a paper towel to wipe off any excess oil from the skillet. The layer should be thin, as a thick layer can become sticky instead of forming a smooth non-stick surface.
Heat the skillet: Place the skillet upside down in an oven preheated to around 375°F to 400°F (190°C to 200°C). Placing it upside down will prevent oil from pooling in the skillet. You can also place a baking sheet or aluminum foil on the bottom rack to catch any drips.
Bake the skillet: Allow the skillet to bake for about an hour. This process will help the oil polymerize and form a non-stick coating on the cast iron.
Cool and repeat (optional): Let the skillet cool in the oven. You can repeat the seasoning process 2-3 times to build up a better seasoning layer.
After seasoning, your cast iron skillet will have a dark, shiny surface that becomes more non-stick with each use. To maintain the seasoning, avoid using harsh detergents or scrubbers that can remove the coating. Instead, clean it with hot water and a gentle brush or sponge. Dry it thoroughly and apply a thin layer of oil after each use to keep it in excellent condition.
Seasoning your cast iron skillet not only makes it more non-stick but also adds depth and flavor to your cooking. With proper care, a well-seasoned cast iron skillet can last for generations.
