Best Oil For Seasoning: Olive Or Canola?

Seasoning a pan is an important step in owning a carbon steel or cast-iron pan. Seasoning helps to protect a pan from rusting and provides a non-stick surface for cooking. The process involves adding a thin layer of oil to a pan and heating it up, which causes the oil to bond to the metal. This process is called polymerization.

When it comes to choosing an oil to season a pan, it is best to opt for oils with a high smoke point, as this means they will only start to smoke or burn at higher temperatures. Oils that are suitable for seasoning pans include canola oil, grapeseed oil, and vegetable oil. Olive oil, on the other hand, is not the best option for seasoning a pan due to its low smoke point of 350°F. If olive oil is used for seasoning, it can start to degrade when the pan is heated, which defeats the purpose of having a protective layer.

Canola oil is a good option for seasoning a pan as it has a neutral scent and a high smoke point

Canola oil is a great option for seasoning a pan. It has a neutral scent and a high smoke point of 400°F, which means it can be heated to a high temperature without burning off. This makes it a good choice for cooking at high heat and for maintaining the seasoning on your pan.

To season a cast-iron pan with canola oil, start by preheating your oven to 350°F. Canola oil has a smoke point of 400°F, so keeping the oven temperature below that is important. Place a layer of foil or a baking sheet under the pan to catch any drips.

Next, thoroughly clean your pan with an abrasive scrubber and dish soap. Cast-iron pans often have a factory coating that needs to be removed before seasoning. After drying the pan with a towel, heat it up on the stovetop for a few minutes to remove any remaining moisture.

Apply a thin layer of canola oil to the entire pan, including the bottom, handle, sides, and interior. You don't need to be too generous with the coating, just make sure the entire pan is covered.

Bake your cast-iron pan upside down in the oven for one hour. This prevents the canola oil from pooling in the bottom of the pan and creating a sticky surface. After baking, let the pan cool in the oven for at least 30 minutes.

Seasoning your pan with canola oil is a simple process, and it's important to repeat it twice a year. If you frequently cook with acidic foods or at high temperatures, you may need to season your pan more often.

Canola oil is a type of vegetable oil made from pressed canola seeds. It has a neutral taste, a high smoke point, and is widely available, making it a popular choice for seasoning pans. Its versatility and high smoke point also make it suitable for frying and cooking at high temperatures.

Olive oil is a popular choice for seasoning cast iron, but it has a low smoke point

Olive oil is a popular choice for seasoning cast iron due to its accessibility and versatility. It is likely that you already have it in your pantry, and it can be used for everything from sautéing to baking. However, it is important to note that olive oil has a relatively low smoke point compared to other oils.

The smoke point of an oil is the temperature at which it starts to smoke and break down. For olive oil, the smoke point typically falls between 325 and 375°F (165 to 190°C), although it can be as high as 410°F. When choosing an oil for seasoning cast iron, it is recommended to select one with a smoke point above the cooking temperature, as this is the most effective temperature range for seasoning cast iron.

The effectiveness of olive oil for seasoning cast iron is influenced by the type of olive oil used. Extra virgin olive oil, for example, has a lower smoke point than refined olive oil due to its higher acidity. Refined olive oil has a smoke point ranging from 390°F to 470°F, while extra virgin olive oil typically falls between 350°F and 410°F.

While olive oil is a popular choice, there are other oils that may be more suitable for seasoning cast iron due to their higher smoke points. Oils such as avocado oil, grapeseed oil, canola oil, and vegetable oil have smoke points above 400°F, making them better options for seasoning cast iron if you plan to cook at high temperatures.

Ultimately, the choice of oil depends on your personal preference and the type of cooking you will be doing. If you prefer the taste of olive oil and mostly cook at lower temperatures, it can be a good option for seasoning your cast iron. However, if you frequently cook at high temperatures, consider using an oil with a higher smoke point to ensure the seasoning process is most effective.

Flaxseed oil is another option but it is expensive and can get brittle and flake off over time

Flaxseed oil is another option for seasoning a pan. However, it is a more expensive option and there are a few things to keep in mind when using it. Firstly, flaxseed oil has a very low smoke point of around 225°F (107°C), so it is important to be careful when heating the oil to avoid reaching its smoke point. Secondly, not all flaxseed oils are created equal – for seasoning cast iron, it is important to use a pure, organic, cold-pressed, and unmixed flaxseed oil that requires refrigeration. The oil should also have a high percentage of omega 3 fatty acids, particularly ALA, which is necessary for effective fat polymerization.

When seasoning a pan with flaxseed oil, the process is similar to using other oils. However, it is important to use a very thin layer of oil, as using too much oil can result in a flaky, sticky coating. The pan should be stripped, scrubbed, and dried before applying the flaxseed oil with a cloth or hands. The oil should then be wiped off, leaving only a very thin layer. The pan is then placed upside down in a cold oven, which is preheated to a high temperature (around 500°F or 240°C). The pan is baked for an hour and then allowed to cool completely in the oven before repeating the process for a total of 4 to 7 times.

While flaxseed oil can result in a smooth, hard, and protective coating on a cast-iron pan, it is important to be mindful of its limitations. The low smoke point means that it can be difficult to achieve the necessary temperature for effective polymerization, especially if your oven doesn't reach high enough temperatures. Additionally, the use of too much oil or improper preparation of the pan can result in a flaky, sticky coating. Therefore, while flaxseed oil can be an effective option for seasoning cast iron, it may require more time and attention compared to other oils.

Grapeseed oil is a great choice for seasoning cast iron as it has a high smoke point and is versatile

Grapeseed oil is a great choice for seasoning cast iron due to its high smoke point and versatility. With a smoke point of around 450°F, grapeseed oil can withstand the high temperatures required for effective cast iron seasoning. The process of seasoning involves heating oil beyond its smoke point to trigger a chemical reaction called polymerization, where the oil bonds with the metal to create a tough, non-stick coating. The higher the smoke point, the better, as it allows for a stronger seasoning layer to form.

Grapeseed oil is also a very versatile cooking oil. It can be used as a replacement for olive oil in many cases and is perfect for sautéing, searing, and baking. Its neutral flavour makes it ideal for a variety of dishes without imparting its own taste. Additionally, grapeseed oil is relatively inexpensive and readily available in most grocery stores, making it a convenient and cost-effective option for cast iron seasoning.

When seasoning cast iron, it is crucial to use a thin layer of oil and repeat the process multiple times to build up a strong, non-stick coating gradually. This method ensures that the oil can properly polymerize and creates a smoother, more durable surface. While grapeseed oil is an excellent choice, other oils with high smoke points, such as canola or sunflower oil, can also be used effectively for cast iron seasoning.

Vegetable oil is a good, cheap option for seasoning cast iron but it can be a little sticky

The role of oil in seasoning cast iron

Seasoning is an important step in owning a cast iron pan. Seasoning is a layer of carbonized oil that gives cast iron its classic black patina. It forms a natural, easy-release cooking surface and helps prevent rusting.

Vegetable oil is a good option for seasoning cast iron

Vegetable oil is recommended by cast iron cookware manufacturers for seasoning because it is flavour-neutral, affordable, effective, and has a high smoke point. A high smoke point is important because it is the temperature at which the oil starts to smoke and break down. The most effective temperatures for seasoning cast iron are between 400-500 degrees Fahrenheit, so you need an oil with a high smoke point to withstand those temperatures.

But vegetable oil can be a little sticky

When using vegetable oil to season cast iron, it is important to apply a very thin, even layer of oil to the cookware. If you use too much oil, your cookware may become sticky. This is because the polymerization process, which creates the seasoning, will not be complete. To fix this, you can scrub the pan with a nylon brush or salt, then rinse, hand dry, and rub with oil. You may also want to try seasoning the pan in the oven to help build up a strong layer of seasoning.
