How to season a cast iron skillet and how often you should do it

If you like cast iron cookware, you might want to know how to season a cast iron skillet. Not only are they sturdy, non-stick, and built to last, but cast iron pans are designed to withstand high temperatures to cook just about anything. From seared steak and pork to fried eggs, you can easily use it as part of your daily preparations.

But, if a cast iron skillet is not seasoned or properly maintained, it can often rust or wear out in the long run. Plus, it can affect the quality of your delicious cooking, especially if your pan starts to lose its non-stick appeal.

So what is seasoning? Essentially, seasoning (not the salt and spice kind) involves forming a protective layer on the iron by heating layers of oil.

2. Add a little oil and rub to coat – Then take the oil of your choice and pour a tablespoon or two into the pan. Be careful not to add too much, as you will only need a thin layer of oil to season. Then, with a clean, dry cloth or paper towel, rub the oil around to coat the entire pan. Once you’ve oiled the inside, don’t forget to do the same for the outside and bottom of the pan.

3. Put the pan in the oven to cook – The key is to place the pan upside down on the middle oven rack to bake for an hour (yes, an hour). It is always a good idea to place aluminum foil just underneath, to catch any dripping oil. Either way, you can always read our tips for how to clean an oven to keep it grease-free and spot-free.
