How To Season And Clean Cast Iron Cookware? [4 Effective Ways]

If you have purchased a new cast iron cookware or have an old one then today you will learn, how to season and clean cast iron cookware?

So once you get cast iron you have to prepare it for use. This is done through a process called seasoning. 

Basically, when you’ve seasoned a pan you are putting fat inside the little ridges and grooves inside of the pan and then baking them to create a slick surface that you can cook. 

The main goal is to get the fat molecules consistently and evenly spread over the cookware and then bring it up to a temperature that allows the fat molecules to polymerize on the pan. This is like creating a matrix webbing over the pan that is sort of permanent.

For a New Pan

Follow the simple directions below:

  1. First, place aluminum foil on the bottom of the oven (this is done to protect the oven from oil dripping) and preheat the oven to 200°F or 93°C.
  2. Now wash the skillet or dutch oven with soap and water and then wipe with a paper towel to dry it.
  3. When the pan completely dried out, place it into the oven for 20 minutes.
  4. After 20 minutes, just remove the skillet from the oven and coat it with a very thin layer of oil (flaxseed, canola, Crisco, lard, etc).
  5. Again, preheat the oven to 450°F or 232°C.
  6. Now, wipe off as much oil as possible using a lint-free paper towel or a soft cloth.
  7. Then, place the pan upside down into the oven for an hour or so.
  8. After the hour is up, turn off the oven and let the skillet cool with the oven.
  9. That’s it, your cast iron cookware is now completely seasoned.
  10. But, to get the best results you have to season your pan at least 3-4 times. Just repeat the steps from 6-8 to re-season the pan.

Note: You can do the same process using a gas stove, just pre-heat the pan for 20-30 mins and then coat it with oil and after wiping, heat the pan for about an hour or so and you are done.

What is the best oil to season a cast-iron skillet?

The best oil to season a cast-iron skillet is flaxseed oil. I prefer flaxseed oil compared to vegetable or coconut oil because it makes the cast iron surface smooth, hard, and even.

On the other hand, vegetable or coconut oil leaves the skillet soft and prone to scratches or wear and tear. You read the science behind this on Sheryl’s blog.

How often do you season cast iron pans?

The newer pans should be seasoned at least 4 to 5 times for smooth cooking. If you follow the cleaning techniques wisely, then you can season once or twice a year.

But, if dip your pan in soap water or rub roughly, then you have to season it again.

How to Clean Black Residue Off Cast Iron Skillet?

According to some experts, the black residue is not bad. It is just the iron mixing with oil comes out of the pan and if you are deprived of iron then this is good for you.

There are many methods to clean it. You can try the same method used to clean the rusted pan or you can also try baking soda, soap, and water methods.

Just sprinkle some baking soda in the pan and leave it for some time. Then wash the pan with dish soap and water. Doing this will wipe off the seasoning but your problem will be solved.

Another method you can try, just after cooking while the pan is somewhat hot, sprinkle some salt in the pan and lightly rub with a paper towel. The salt will collect the black residue and largely disinfect the skillet. The abrasive properties of the salt help to clean the residue.

After doing this, wipe out the brown salt from the pan and pour some oil in the pan and rub with a paper towel and store it.
