I. Introduction
In the realm of culinary tools, cast iron cookware stands out for its exceptional durability, heat retention, and natural non-stick properties. However, to fully unlock its potential, cast iron requires a process known as seasoning, which creates a protective layer that enhances its performance and prevents rust. Among the various oils commonly used for seasoning, olive oil has sparked debate due to its unique characteristics and potential drawbacks.
II. What is Cast Iron Seasoning?
Seasoning is an essential step in cast iron cookware maintenance. It involves applying a thin layer of oil to the cast iron surface and then baking it in a high-temperature oven. This process creates a polymerized layer of oil that adheres to the cast iron, forming a protective barrier against rust and promoting a non-stick surface.

III. The Traditional Method of Seasoning Cast Iron
The traditional method of seasoning cast iron typically involves using vegetable shortening, canola oil, or animal fat. These oils have high smoke points, making them suitable for the high temperatures required during the seasoning process.
Step-by-Step Guide:
- Wash and dry the cast iron thoroughly.
- Apply a thin layer of oil to all surfaces of the cast iron, including the interior, exterior, and handle.
- Preheat the oven to 350-400°F (175-200°C).
- Place the cast iron upside down on a baking rack in the preheated oven.
- Bake for one hour.
- Turn off the oven and let the cast iron cool completely inside.
- Repeat steps 2 to 6 two to three more times to build up a strong seasoning layer.
IV. The Use of Olive Oil for Seasoning Cast Iron

VII. FAQs about Seasoning Cast Iron with Olive Oil
Can I use extra virgin olive oil for seasoning cast iron?
Yes, high-quality extra virgin olive oil is suitable for seasoning cast iron. It offers a relatively high smoke point and enhances the flavor of the seasoned cookware.
How often should I re-season my cast iron cookware?
The frequency of re-seasoning depends on how often you use your cast iron cookware. With regular use, you may only need to re-season once or twice a year. However, if you use your cast iron less frequently or if you notice that the seasoning is starting to wear off, you may need to re-season more often.

Some users report that coconut oil and avocado oil can leave a slightly sticky residue, so it may take some experimentation to find the right method for using these oils.
Can I use olive oil to season enameled cast iron cookware?
No, you should not use olive oil to season enameled cast iron cookware. Enameled cast iron already has a protective coating, so seasoning is not necessary. In fact, using olive oil to season enameled cast iron could damage the coating.
Can I use olive oil to season cast iron griddles or grill pans?
Yes, you can use olive oil to season cast iron griddles or grill pans. The same process applies as for seasoning skillets or Dutch ovens. Just be sure to choose high-quality extra virgin olive oil and apply multiple layers of seasoning to ensure a durable non-stick surface.
