Yes, it is recommended to season a new cast-iron skillet before cooking eggs or any other food in it. Seasoning is the process of creating a natural, non-stick cooking surface by coating the skillet with a layer of polymerized oil. This not only enhances the non-stick properties but also helps protect the cast iron from rusting and improves its overall longevity.
Here's how you can season a new cast-iron skillet:
Wash the skillet: Start by washing the skillet with warm, soapy water to remove any factory residue or coatings. Use a sponge or brush to scrub gently. Avoid using harsh abrasives that could damage the surface.
Dry it thoroughly: After washing, make sure to dry the skillet completely using a clean towel or by placing it over low heat on the stovetop.
Apply oil: Choose a high-smoke-point oil like vegetable oil, flaxseed oil, or grapeseed oil. Pour a small amount of oil onto a paper towel and rub it all over the interior and exterior surfaces of the skillet, including the handle.
Remove excess oil: Wipe off any excess oil with a clean paper towel. The skillet should have a thin, even coating of oil.
Bake the skillet: Place the skillet upside down in an oven preheated to around 375°F (190°C). Put a sheet of aluminum foil or a baking sheet on the bottom rack to catch any dripping oil. Bake the skillet for about 1 hour.
Cool and repeat: After an hour, turn off the oven and let the skillet cool down in the oven. If you feel the first seasoning layer is not sufficient, you can repeat the process by adding another layer of oil and baking again.
Properly seasoned cast-iron skillets develop a natural non-stick surface over time and with repeated use. When you are ready to cook eggs, preheat the skillet on medium-low heat, add a little cooking oil or butter, and then cook your eggs as usual. Over time, the seasoned surface will improve, and your cast-iron skillet will become an excellent tool for cooking eggs and a variety of other dishes. Remember to avoid using soap when cleaning your seasoned skillet, as it can remove the seasoning layer. Instead, clean it with hot water and a brush or non-abrasive sponge, and then dry it thoroughly to prevent rusting.
