How to Season Cast Iron: A Comprehensive Guide


Greetings Challenger, and welcome to this comprehensive guide on how to season cast iron. Seasoning is an essential process in the care and maintenance of cast iron cookware. If done correctly, it enhances the non-stick properties of the pan, prevents rusting, and prolongs its lifespan. In this article, we’ll go through the step-by-step process of seasoning cast iron, so you can enjoy cooking with it for years to come.

What is Cast Iron?

Cast iron is a type of metal that is used in cookware such as skillets, frying pans, Dutch ovens, and griddles. Cast iron cookware is known for its durability, heat retention, and even cooking. In addition to its practical uses, it also adds a rustic charm to any kitchen. However, cast iron cookware requires seasoning to protect it from rusting and to achieve its non-stick properties.

Why is Seasoning Important?

Seasoning is the process of adding a layer of oil to the surface of your cast iron cookware and heating it to create a non-stick coating. It also protects the cast iron from rusting and makes it easier to clean. Without seasoning, cast iron cookware can become rusted, damaged, and stick to food. Proper seasoning creates a protective barrier that prevents these issues and ensures your cast iron cookware remains in excellent condition for years.

What Oil is Best for Seasoning Cast Iron?

When seasoning cast iron, it’s essential to use an oil with a high smoke point, such as canola oil, vegetable oil, grapeseed oil, or flaxseed oil. Flaxseed oil is our recommended choice, as it polymerizes to create an even stronger non-stick coating. However, it’s essential to use a food-grade flaxseed oil and follow specific instructions to achieve the best results.

What Temperature Should Cast Iron Be Seasoned At?

To season cast iron, you’ll need to heat your oven to 400°F – 450°F (204°C – 232°C). You can also season cast iron on the stovetop, but for optimal results, we recommend seasoning cast iron in the oven.

How Often Should You Season Cast Iron?

The frequency of seasoning your cast iron cookware depends on how often you use it. If you use cast iron regularly, you should season it every few months. However, if you use your cast iron cookware less often, you may only need to season it once a year or less.

Can You Use Soap to Clean Cast Iron?
