The Best Oil to Season Cast Iron and How to Season Them Properly!

best oil to season cast iron

A cast-iron pan or skillet can be your best friend in the kitchen, but it requires extra attention. Known as the first “non-stick” skillet, cast iron utensils are used by people worldwide. And since they are not chemically treated, they require some extra help, unlike your Teflon cookware. Today I will teach you how to season cast iron skillets properly and the best oils/fats to use to season them.

With so many options for oils out there, starting from olive oil to coconut oil, the possibilities are endless. So it is normal to get confused when choosing the best oil for seasoning your pan.

I shall help you narrow down the list.

What to Consider While Choosing Oil for Seasoning

Neutral oils: Oils that have mild and low flavor. Examples: canola oil, vegetable oil, sunflower oil, grapeseed oil, etc.

High smoke point oils: Oils that start smoking or burning at high temperatures. Example: coconut oil, palm oil, corn oil, etc.

Cheap and inexpensive oils: Budget-friendly oils.

Things to Avoid:

× Flavored oils: Oils made from nuts are usually flavored oils: Peanut oil, almond oil, etc.  

× Low smoke point oils: Never use oils with low smoke points.

× Infused oils: Infused oils are simply a waste when it comes to seasoning and should be left for cooking

Always choose neutral oils and oils with high smoke points. And if you are on a budget, go for the cheaper options as long as they are neutral and have high smoke points.

Considering those facts, I came up with a top 5; are Seasoning sprays, Canola oil, Vegetable oil, Flaxseed oil, and, lastly, Grapeseed oil.

These oils had very few differences, but overall I found Grapeseed oil to be the best as it is cheap, versatile, readily available, and yes, it gets the job done perfectly.

Now you might be wondering, are cast iron products worth all the hassle? Let me explain.

To begin with, let us first see what seasoning cast iron skillet means.

What Does Seasoning Mean in Cast Iron Skillets?

“Seasoning cast iron skillets” in simple terms means adding a thin layer of oil or fat on the surface of cast iron cookware to make them non-stick and prevent rust and oxidation. In the case of cast iron utensils or Dutch ovens, the seasoning has nothing to do with salt and pepper.

Cast iron skillets are made from pure iron and carbon and are molded into a skillet or pan. They have a very porous surface, and as a result, they have small gaps and bumps on the surface. These may not be visible to the naked human eyes, but it is a very uneven surface.

To fill up these uneven cooking surfaces, they are seasoned with oils. The oil gets inside these uneven parts, creates a smooth surface, and bonds with the cast iron cookware. That is why cast iron skillets get smoother over time, and the more you use them. 

Now let us learn how to season cast iron and the seasoning process.
