Which oil is best for seasoning cast iron?
All cooking oils and fats can be used for seasoning cast iron, but based on availability, affordability, effectiveness, and having a high smoke point, Lodge recommends vegetable oil, melted shortening, or canola oil, like our Seasoning Spray.
Higher Concentration of Unsaturated Fat
Unsaturated fats have a chemical makeup that is more optimal for polymerization, the process that needs to occur to develop the perfect cast iron seasoning. So steer clear of oils with a higher concentration of saturated fats, like coconut oil and palm oil.
Instead of adding a light coat of oil, it will burn. Seasoning with olive oil will soon degrade and add smoke flavor to your food. Oil for cast iron should have a high smoke point, so olive oil is not a good choice.

Does olive oil make cast iron sticky?
Suppose you intend to use butter or olive oil for baking your cast iron. It's not the best option. Both burn easily at low temperatures, and that is not ideal for seasoning. It will leave residue on the cookware, which will become sticky.
Using too much oil, anything more than about the size of a quarter will just build up and cause an oil slick on your pan. When it's time to season your cast iron skillet, you simply can't do this with a cold skillet. This will cause build up of that oil residue, and cause stickiness.

Both are pretty amazing. But cooking eggs in a cast iron pan can be a bit of a sticky situation if you are not as seasoned as your skillet. For some reason, cast iron can cause your fried eggs to stick.

Cast iron can be pretty resilient, and even very rusty, damaged pans can be rehabilitated—and in most cases, the rust they're facing is pretty minor. It's important to note that you shouldn't use your skillet while it still has rust on it.
Although cast iron is very durable, it will rust when exposed to water or air, making the seasoning step crucial. Soaking with soap, over-scrubbing, or cooking highly acidic foods in cast iron can strip the seasoning. Clean your cast iron each use, wiping away leftover food morsels and reapplying the oil layer.
An easy way to test a skillet's seasoning is to fry an egg (heat 1 tablespoon vegetable oil in skillet over medium heat for 3 minutes, then add egg). If your pan is well-seasoned, you should not experience any major sticking.
When is too much too much? Although it seems odd, it is technically possible to over-season a skillet. Too much oil baked into the cast iron will cause it to polymerize unevenly and eventually will cause the surface of the skillet to flake.
Make sure to place it upside down so the oil doesn't settle unevenly in the pan. During this time, the polymerization process takes place and the oil is transformed into a smooth coating for your cast iron. Let it cool.
Sticky Surface
If the seasoning in your pan is sticky, this is a sign of excess oil built up on the cookware. The Fix: To remedy stickiness, place the cookware upside down on the top rack of the oven and bake at 450-500 degrees F for one hour. Allow to cool and repeat if necessary.

Many manufacturers pre-season their cast iron before selling it, but it's still a good idea to know how to prepare because it's recommended maintenance two or three times a year.
