How To Season Cast Iron Without Oven

Seasoning cast iron skillets is not a very complicated process whether you use an oven or a stovetop.

All you need is a couple of things to get you started:

– Cloth or Paper towel

– Light cooking oil, you can use vegetable oil, canola oil, corn oil, olive oil, or flaxseed oil

– Cast iron pan

Using cooking oils with unsaturated fat is recommended because they are more reactive and can create a better layer of protection in your cast iron pans. Although, some people season their pans with oils high in saturated fat like bacon grease or lard.

  1. Clean And Dry The Cast Iron Pan

Before anything else, clean your cast iron pan first, especially if it is new and fresh out of its packaging.

To clean your cast iron pan, wash it with warm water and soap and gently scrub it with a non-abrasive sponge. You do not want to scrub the pan aggressively as it can remove the coating.

Make sure to let the pan completely dry before you start the seasoning process. After drying your pan with a towel, you can put it on your stovetop and heat the pan for a few minutes.

  1. Add The Oil

After the pan has completely dried, pour vegetable oil, or your preferred cooking oil, on a clean paper towel and rub it all around the pan, including the outside and the handle. Remove any excess oil with another clean paper towel, leaving only a light coating of oil left around the pan.

The cast iron pan should only have a shiny coat to it and not should not be dripping with oil.

  1. Place The Oiled Cast Iron Pan On The Stove

Once your cast iron pan has been coated with oil, put the pan on the stovetop and let it sit on medium heat for about 10 minutes or until the pan has completely dried out. You can move the pan around while it is heating up so the heat can be evenly distributed around the pan. Be careful when moving the pan around as it is hot.

Also, since the oil will go past the smoking point, you want to make sure that your area is well-ventilated to keep the smoke out.

Once that pan has dried out, turn off your stove and let the pan cool down. Do not put the pan under running water or even let water sit on the pan to let it cool down as you might risk damaging your pan.

Your cast iron pan might look mottled at this stage.

  1. Repeat The Heating Process Three To Four Times

After your pan has cooled down, wipe some excess oil if there is any.

Repeat steps 2 and 3 for three or four times until the pan is no longer mottled and is looking smooth, dark, and shiny. Repeating the process several times ensure that the layers form correctly and you have a good layer of protection on your cast iron pan.
