3 Simple Ways to Season Cast Iron 

Below please find the most common ways to season cast iron quickly and effectively.

Seasoning Cast Iron in Oven

We call this seasoning method the standard one. For many decades, oven seasoning is the most recommended method to season new and old cast-iron items. And you will not find any other method simpler than the oven seasoning. Here is how you do that:

  • Apply a thin layer of oil on cast iron skillet and put it upside down in an oven.
  • Pre-heat the oven before keeping the skillet.
  • Ideal oven temperature for seasoning is 450 to 500 degrees.
  • Let it in the oven for about 60 minutes to 90 minutes.
  • Now, turn off the oven and let it cool down.


The method is simple, and you can do it without any hassles. However, ensure that the oven is pre-heated correctly before placing the skillet in the oven.


As compared to other seasoning ways, oven seasoning takes about 3 to 4 hours. So, in this way, it is time-consuming.

Cast Iron Stovetop Seasoning

Stovetop seasoning is the most preferred method of seasoning for experts and professional chefs. The stovetop seasoning is relatively simple and the most effective seasoning way for cast iron utensils and cookware. Here is how you do that:

  • Apply a thin coating of oil, preferably vegetable oil all over a cast iron pan.
  • Don’t forget to apply the oil on the backside of the pan.
  • Now place it on a stove till you notice a lot of smoke.
  • Keep it for at least 20 to 25 minutes on the stove.
  • There will be a lot of smoke, so be cautious.
  • Now, remove it and let it cool down entirely before usage.


Stovetop seasoning is quick. You can do that in about 30 minutes from start to finish. Another main benefit of this method is that you will not be using your oven for hours.


There will be a lot of smoke. So, if you are suffering from any respiratory problem, stovetop seasoning is not recommended for you.

No Seasoning

Some of might be surprised to know that “many experts do not like seasoning” of any kind. And one such expert is Dennis Powell of Butter Pat Industries. According to these class of experts rather than seasoning specifically by using any method you just “grease the pan with lard and cook.” That’s all. Another thing that experts recommend when you follow no seasoning method is that always cook high-fat content first in your cast iron skillet. As per experts, if you frequently cook high-fat content, you don’t need any seasoning.


Factually there will be no work of any kind for you to do. No oven usage, no smoke, no oil.
