Does food stick in your cast iron griddle? It’s either you did not season the griddle or did not season it properly. The proper way on how to season cast iron griddle will allow you to enjoy your griddle for long years.

Seasoning is the first step you need to do with a cast iron griddle or with one that has not been used for a long time. Seasoning is the process of scrubbing, oiling and baking cast iron cookware to make it a non-stick surface and for rust protection.

Many modern cast iron griddles are already pre-seasoned out of the box. It is however best to season it again to add another layer before its initial use.

Cast iron is a preferred cookware material for many homeowners as well as novice and professional chefs.

The Principle of Seasoning

Iron, as everyone knows is highly prone to rusting therefore so does your cast iron griddle. The principle behind seasoning is to apply layers of fat to serve as a protective coat for rusting and sticking.

As fats are heated on the cast iron griddle, polymerization occurs.  Polymerization is the process of heated fats bonding with metal where fats will convert into a plastic-like coating. After polymerization cast iron is protected against rust and also becomes a non-stick cookware.

Procedure - How to Season Cast Iron Griddle

  1. Wash griddle in hot soapy water with a stiff brush or sponge to remove factory wax. Although it is not advisable to wash cast iron in soap, this step is fine because anyway it is part of the seasoning process. 
  2. Thoroughly dry out the griddle with a clean dry cloth or paper towels. You can also place it on the hub on medium heat for about 15 minutes to allow moisture to evaporate.
  3. Place aluminum foil on the lower rack of the oven. The foil will catch the drippings from the griddle. 
  4. Pre-heat oven to 375°.
  5. Coat both sides of the griddle with a thin layer of vegetable oil. Rub the oil all over the griddle. Make sure not to miss the corners. 
  6. Bake griddle on the center rack of the oven. 
  7. Turn heat off and allow the griddle to cool inside the oven.

You will know that your cast iron griddle has been properly seasoned if it has a shiny and smooth non-stick surface. You will know when your cast iron griddle needs to be re-seasoned when you notice some rust, it appears dull and it is no longer non-stick.

Many homemakers think that having a cast iron griddle entails constant seasoning to keep it rust-free and non-stick. Truth is the more you cook in your cast iron griddle, the fats you use continuously seasons the griddle. You will only need to re-season when you were not able to properly clean and store your cast iron griddle.

Caring for Cast Iron Griddle

Rust is the number one enemy of your cast iron griddle. It is important that you clean your cast iron griddle after each use (while still warm) to prevent it from rusting. Avoid soaking or leaving the griddle in the sink unclean because it will surely rust.

Wash the griddle with hot water using a stiff brush or sponge. Never place the griddle in the dishwasher nor use steel wool or soap as these will remove the griddle’s seasoning. After washing, thoroughly dry the griddle and apply a thin coat of vegetable oiland store in a dry place.

If you unintentionally used soap or any abrasive materials to clean your griddle, simply re-season it and your griddle will be as good as new.


A cast iron griddle or any cast iron cookware for that matter is tough and durable as long as it is properly seasoned, cleaned and stored. It is also advisable that it be pre-heated before cooking so you will not have any problem with food sticking on it.
