How To Season Cast Iron Skillet

Your cast iron skillet needs to be clean before seasoning. Wash it thoroughly and dry it quickly with a paper towel. Rub the clean cast iron skillet with grapeseed oil all over and bake in the oven at 450 degrees F for half an hour.

There are also other tips related to seasoning cast iron skillets. After the initial seasoning process, it is recommended that you use your cast iron skillet for cooking fatty meats and oily foods for the first few uses.

Also, avoid cooking delicate foods in your cast iron pan, such as eggs and fish, at least until you used your cast iron skillet for 10 times already. Another thing to avoid is acidic foods, such as wine, vinegar, citrus fruits, and even tomatoes.

Always use hot water for washing your cast iron pans, and don’t ever soak them. Only use dish soap when you cooked something that was very aromatic. After each washing, dry the cast iron skillet quickly and thoroughly and buff it with a small amount of seasoning oil.

What Is The Best Oil To Use For Seasoning Cast Iron?

Grapeseed oil is by far the best choice for seasoning cast iron skillets, but many other alternatives are being used instead, so let’s take a quick look at the pros and cons of using each one of them:

  1. Flaxseed oil is a popular choice for cast-iron seasoning oil. Flaxseed oil is used mainly because it makes cast iron surfaces smooth and hard, making them resistant to scratches and wearing.
    However, flaxseed oil has a very low smoke point of only 225 degrees F, which makes it not so good for cooking at high temperatures. It is also relatively expensive, and it quickly goes rancid.
  2. Avocado oil is also used as oil for seasoning cast iron cookware because it has a high smoke point of 520 degrees F, long shelf life, and makes a tough coat of seasoning on cast iron pans and skillets.
    Although it sounds perfect, avocado oil has a huge drawback – it is significantly more expensive than most other cooking oils.
  3. Canola oil can also be used for seasoning cast iron skillets, but it won’t yield as good results as the options above. The first canola oil seasoning might create a bumpy surface, and it will be overall weak, with food starting to stick much sooner than with some other cooking oils.
    Not everything is bad when it comes to canola oil though. This type of vegetable oil has a relatively high smoke point of 400 degrees F, and it is insanely cheap.
  4. Olive oil is something you should never use to season cast iron cookware. We only included it in our list to warn you how bad it is for seasoning cast iron skillets, despite its low price and well-known health benefits.
    Even the extra virgin olive oil is a bad choice because of its low smoke point of 375 degrees F, and it can release harmful chemicals when burning.
  5. Similar to canola oil, sunflower oil has a high smoke point of 450 degrees F and a light flavor that won’t compete with the other ingredients.
    However, this vegetable oil is weak when used as a cast-iron seasoning oil, and you will need to re-season more often than with other choices.
  6. Coconut oil has a delicious flavor and a high smoke point of 450 degrees F, but we advise you against using coconut oil for seasoning cast iron skillet.
    Coconut oil is rich in saturated fats which means the seasoning won’t harden well. Virgin coconut oil has a much lower smoke point of 350 degrees F. Coconut oil flavor might not go so well with some dishes.
  7. Peanut oil also has a distinct flavor that might overpower and ruin some dishes when being used as a seasoning for cast iron skillet. Also, seasoning your cast iron skillet with peanut oil might be dangerous if you use that same skillet to cook for someone who has a peanut allergy.
    On the other hand, peanut oil is relatively inexpensive, and it has a high smoke point of 450 degrees F.
  8. Finally, bacon grease is also used for seasoning cast iron pans, and it has its own set of pros and cons. Bacon grease will keep your cast iron skillet non-sticky and smooth, but its flavor might be overpowering for some dishes.
    Also, it is needless to say that cast iron skillets shouldn’t be seasoned with bacon grease if you plan to use them for cooking vegan and vegetarian meals. in that case, make sure to use vegetable oil instead.

You can use other options instead of grapeseed oil for seasoning cast iron skillets, but each one of them has some flaws that make it inferior when compared to grapeseed oil.

If you don’t mind its price, avocado oil is the best alternative to grapeseed oil when it comes to cast iron seasoning oils. It has a high level of unsaturated fats crucial for cast iron seasoning, and a high smoke point.

Can I Season Cast Iron With Coconut Oil?

You can use coconut oil to season the cast iron pan, but it’s not the best choice. Virgin coconut oil has a low smoke point of 350 degrees F, and its distinct flavor might not go so well with many dishes.

Refined coconut oil has a higher smoke point of 450 degrees F, but it is also high in saturated fats, which lowers the polymerization that’s required for the seasoning process, and as a result, the seasoning won’t harden well.
