Do You Want to Know Which Oils Are Not Recommended for Seasoning Cast Iron?

For seasoning cast iron, flaxseed oil, olive oil, and oils with low smoke points are generally not recommended by Users, along with non-food-safe oils like motor oil.

Oils to Avoid

Flaxseed Oil: Many Users report that flaxseed oil, despite early recommendations, often results in a seasoning that is brittle and prone to flaking or peeling. "Flaxseed has a very low smoke point and also produces an incredibly brittle and flaky seasoning."

Low Smoke Point Oils: Oils with low smoke points, such as regular olive oil, can cause excessive smoking and lead to a spotty or sticky seasoning. "Anything with a low smoke point should be avoided."

Non-Food-Safe Oils: Obviously, any oil not intended for consumption, like motor oil, should never be used to season cast iron. "Motor oil isn’t good for seasoning."

Other Considerations

Allergies: While peanut oil works for seasoning, some Users advise against it due to potential severe allergic reactions for household members or guests. "The main downside of using peanut oil is if anyone in your household or a possible dinner guest happens to be allergic to peanuts."

Ghee/Coconut Oil: Some Users suggest avoiding ghee and coconut oil due to their low iodine number, which can result in less effective seasoning. "Don't season with ghee nor coconut oil. Doesn't work well due to low iodine number."
