Top 5 Best oil to Season Cast Iron – Picked by Experts

Top 5 Best oil to Season Cast Iron – Picked by Experts

As we know, seasoning is a must for all cast iron cookware. And the most important thing that you need for a proper seasoning is an oil. For seasoning purposes, you need an oil that has a low smoke point, and that can rapidly oxidize and carbonize due to the heat. It’s because of the burning oil that forms the non-stick coating on the surface of the cast iron cookware.

However, when it comes to perfect and proper seasoning, the low-smoke oils are the best compared to the high smoke points such as peanut, sunflower, safflower, or soybean oil.

To determine which is the best oil to season a cast iron cookware, the simple answer would be the one that can survive and smoke at high heat or temperatures. If you want to use nut or vegetable oils, they should be refined.

To assist you in determining the correct oil for seasoning, below are our recommendations for you.

Why we need to Season Cast Iron

Seasoning a cast iron skillet or any other cookware makes the surface non-stick. Due to this non-stick surface, there is less need for butter, fat, or oil when cooking. Well-seasoned cookware is also simple to maintain and clean. And it is less prone to rust, which results in long-lasting working life. When you use a thin coating of oil on the cast iron and heat it, it evaporates like smoke. And there is only carbon polymer left that is bonded to the cast iron.

This creates a barrier that safeguards the cast iron cookware from the air so it will not rust. In this way, the seasoning also protects cast iron from rust and corrosion.

Conversely, a well-seasoned cast iron cookware might not be as non-stick as Teflon, but it is much better than the stainless steel.

By performing a proper and correct seasoning, bare iron cookware can develop a non-stick surface without any toxic or synthetic coatings.
