Is Olive Oil Good for Seasoning Cast Iron?
If you’re wondering whether olive oil is a good choice for seasoning your cast iron pan, you’re not alone. Many home cooks want to know which oils work best to create a sticky, durable coating that protects the pan and improves its performance. Olive oil, a kitchen staple known for its health benefits and delicious flavor, often comes up in this debate.
While olive oil can be used for cooking, its suitability for seasoning cast iron depends on its properties. Seasoning is the process of baking a thin layer of oil onto the iron surface to create a natural non-stick coating. The key factors in selecting an oil are its smoke point and how well it polymerizes, or hardens, when heated. Olive oil has a moderate smoke point—around 375°F for extra virgin olive oil—making it lower than many other oils used for seasoning.
Because of its lower smoke point, olive oil is more likely to burn or smoke during the seasoning process. This can lead to a sticky or uneven layer instead of a smooth, hard coating. However, some home cooks have successfully used olive oil for seasoning by applying thin layers and baking at lower temperatures. Keep in mind that extra virgin olive oil contains more impurities and natural compounds, which can affect how well it polymerizes.
Many experts recommend using oils with higher smoke points for seasoning, such as flaxseed oil, vegetable oil, or grapeseed oil. These oils tend to create a more durable and even seasoning layer because they polymerize more effectively at higher temperatures. For example, flaxseed oil, which has a smoke point around 420°F, is popular because it forms a tough, resilient coating.
However, if you prefer to use olive oil, you can still do so with some precautions. Here are a few tips:
- Apply a very thin layer of olive oil to the pan to prevent sticky buildup.
- Heat the oven to a moderate temperature, around 350°F, to reduce smoking and burning.
- Bake the pan for about an hour, then let it cool completely before wiping off any excess oil.
- Repeat this process multiple times to build up a good seasoning layer.
Keep in mind that seasoning with olive oil might require more frequent re-seasoning or touch-ups because the coating may not be as hard or durable as those made with higher-smoke-point oils. Over time, if you notice your pan’s surface becoming sticky or uneven, switching to an oil with a higher smoke point can help improve the seasoning quality.
Here is a visual guide on seasoning with olive oil:
In conclusion, while olive oil can be used to season cast iron, it is not the best choice for everyone. If you decide to give it a try, do so with caution and focus on applying thin layers at lower temperatures. For long-lasting, resilient seasoning, many home cooks recommend opting for oils designed specifically for cast iron seasoning. Ultimately, the best oil is one that creates a smooth, durable finish and suits your cooking style.
How to Properly Season Cast Iron Pans
Seasoning a cast iron pan is the key to making it non-stick, durable, and easy to clean. Proper seasoning creates a natural coating that protects the skillet from rust and enhances cooking results. Whether you are seasoning a new pan or restoring an old one, following the right steps will give you the best results.
Let’s walk through the simple process of seasoning your cast iron skillet the right way. It might seem tricky at first, but with practice, it becomes part of your regular kitchen routine.
Preparing Your Pan
- Start by washing your cast iron skillet with warm water. Use a gentle brush or non-abrasive scrubber to remove any dirt, dust, or factory coatings.
- Dry the pan thoroughly with a clean towel or place it on the stove over low heat for a few minutes to evaporate any remaining moisture. A dry pan is essential to prevent rust.
Applying Oil
Next, choose a cooking oil with a high smoke point—such as flaxseed oil, vegetable oil, or shortening. These oils polymerize well and create a durable layer of seasoning. Avoid using butter or olive oil as they may smoke at high temperatures and don’t form as strong a coating.
Apply a thin, even layer of oil all over the pan, including the handle and the bottom. You can use a cloth or paper towel to spread the oil smoothly. Less is more here—an excess oil layer can result in sticky spots instead of a smooth finish.
Heating the Pan
- Preheat your oven to about 450°F (230°C). This temperature is ideal for polymerizing the oil and creating a solid coating.
- Place the oiled skillet upside down on the middle oven rack. To catch any drips, put a sheet of aluminum foil or a baking sheet on the rack below.
- Bake the skillet for about one hour. This heat transforms the oil into a tough, protective layer.
- After the time is up, turn off the oven and let the pan cool down completely inside the oven. Cooling helps set the seasoning and avoid warping.
Repeat if Necessary
If your skillet is brand new or needs a restoration, repeat the application and baking process two or three times. Each layer builds up a better non-stick coating and prolongs the life of the pan.
Additional Tips for Perfect Seasoning
- Always clean your pan without harsh soaps, which can strip away the seasoning. Instead, use hot water and a soft brush.
- Avoid using abrasive scrubbers that can scratch the seasoned surface.
- After cooking, wipe the pan with a cloth to remove food residues. If needed, reapply a small amount of oil before storing.
- Keep your cast iron dry and store in a dry place to prevent rusting.
With proper seasoning, your cast iron skillet will become a trusted kitchen tool that provides delicious, evenly cooked meals for years to come. Just remember to maintain it regularly by cleaning gently and re-seasoning when needed. Happy cooking!

Does Olive Oil Have a High Smoke Point?
Many home cooks wonder if olive oil is suitable for high-heat cooking, especially when seasoning or cooking with cast iron pans. The quick answer is that olive oil’s smoke point varies depending on its type and quality. But generally, it has a moderate smoke point compared to other oils.
The smoke point is the temperature at which oil begins to produce smoke, indicating that it’s breaking down. When oil smokes, it can develop an unpleasant flavor and may even release harmful compounds. So, knowing how olive oil behaves at different temperatures helps you cook safely and get the best results.
Understanding Olive Oil Types and Smoke Points
Extra virgin olive oil, which is less processed and retains more of its natural flavors, has a lower smoke point. Typically, it starts to smoke around 375 to 410 degrees Fahrenheit (190 to 210 degrees Celsius). Light or refined olive oils, on the other hand, go through more processing to remove impurities and have a higher smoke point, usually around 465 to 470 degrees Fahrenheit (240 to 245 degrees Celsius).
This difference matters because if you’re sautéing vegetables or frying, you’ll want to choose a more refined olive oil to prevent smoking. Extra virgin olive oil is best used for drizzling over salads, finishing dishes, or low to medium heat cooking.

Common Mistakes When Caring for Cast Iron
Cast iron cookware is beloved for its durability and excellent heat retention. But to keep it in top shape, it’s important to avoid common mistakes when cleaning and caring for it. Many new cooks make simple errors that can damage the seasoning or cause rust. Learning what to watch out for helps your pan last for generations.
One of the biggest mistakes is using soap excessively. While a little soap won’t ruin your cast iron, harsh or too-frequent washing with soap can strip away the seasoning—the natural non-stick coating on your pan. Instead, many experienced cooks prefer to simply rinse the pan with hot water and use a brush or scraper to remove stuck-on bits. For stubborn residue, a bit of coarse salt can act as an abrasive scrub. Remember, the goal is to keep the seasoning intact, so gentle cleaning methods are best.
Another common error is soaking the pan in water. Cast iron is prone to rust if it is left wet for too long. After washing, always dry your pan thoroughly with a towel or a heat source like the stove or oven. Even a small amount of moisture left on the surface can lead to rust spots that are tricky to remove. To prevent this, some cooks like to lightly oil the pan after drying, creating a protective layer that shields against moisture.
Applying too much oil during seasoning or maintenance can also cause problems. While oil is essential for creating that beautiful non-stick surface, using excessive amounts can lead to a sticky, uneven coating. To avoid this, apply a thin layer of oil and buff it into the pan with a paper towel. Before storing, wipe away any excess oil to keep your pan smooth and shiny. Over-oiling can trap moisture or dust, which might lead to a sticky buildup or rust over time.
Yep, you read that right—storing your cast iron improperly can cause issues. Avoid keeping your pan in damp areas or stacking it without protection. If you stack cast iron pans, place a paper towel or cloth between them to absorb any moisture and prevent scratches. Proper storage keeps your cast iron rust-free and ready to use whenever you need it.
Lastly, neglecting regular maintenance can fade the seasoning and cause your pan to deteriorate. To keep it in prime condition, lightly re-season your cast iron every few months. This involves applying a small amount of oil and baking the pan in the oven. Regular seasoning restores its non-stick surface and provides a shield against rust and damage.
- Don’t use harsh detergents or soak your pan in water.
- Always dry your cast iron thoroughly after cleaning.
- Apply a thin layer of oil for seasoning and maintenance.
- Store in a dry, protected spot and use a barrier if stacking.
- Regularly re-season your cast iron to maintain its surface.
By avoiding these common mistakes, your cast iron cookware will stay in excellent condition, perform well, and last for many years. Proper care turns a simple skillet into a treasured kitchen tool that only improves over time.
Can Olive Oil Damage Your Cast Iron?
