Which Oils Should You Use to Season a Cast Iron Pan?
Grapeseed Oil – This oil is my choice for seasoning my cast-iron currently
The type of seasoning oil you use on your cast iron pan will determine the quality and effectiveness of the coat you create.
Grapeseed oil is considered the best cast iron seasoning oil due to its high smoke point. It’s also one of the most versatile oils you can find out there.
Grapeseed seasoning oil contains 10% saturated fat, 16% monounsaturated fat, and 70% polyunsaturated fat.
Its high smoke point of 420 degrees Fahrenheit means that you have to heat up the pan past that point for the oil to start breaking. So, it won’t smoke easily when seasoning your pan.
While grapeseed oil has almost similar properties to flaxseed, it’s a more affordable option. This makes it the best season oil, and that’s why we highly recommend it.
The best thing about grapeseed oil is that it blends well with most flavors, giving your dish a great taste.
Nonetheless, you will want to be careful when buying grapeseed oil as some cold-pressed and virgin types have a lower smoking point.
Flaxseed oil has a smoking point of 225 degrees F but still makes one of the best seasoning oils used on cast iron pans.
Naturally, flaxseed oil will dry out forming a hard layer over the pan’s surface. If you are looking for a durable and versatile oil, then this is a good one.
It bonds with the pan surface creating a perfect, sleek, and non-stick surface for ideal cooking and easy washing.
However, to reap these benefits of cast iron, you have to use unfiltered and organic flaxseed oil. This means it should not be mixed with other oil types and should not have any additives and flavors.
Vegetable oils are an incredible option when it comes to seasoning cast iron. They have an almost neutral taste. Thus, they add little to no flavors to your food.
An excellent example of vegetable oil is canola oil. It forms a solid bond with the cast iron material for an extended seasoning period.
Perhaps the best part of vegetable oil is its availability in local shops and markets and at an affordable price.
Like most vegetable oils, Canola is among the most commonly used oil in most homes today. The main reason this oil is popular is its low price. You don’t have to dig deep into your pockets to get several liters of this oil.
It also has a relatively high smoking point which is just right to season even cast-iron pans.
Canola oil is highly refined, meaning it is the last resort for cooking healthy foods. It’s not the most nutritious oil for cooking.
However, you can take advantage of the high smoking point when seasoning your cast iron on the outside. In this way, it will not come in contact with the food that you want to cook.
Most people would preferer using soybean oil for seasoning their cast iron pan because of several reasons.
The main reason is its high smoking point of 453 degrees F. This means it can withstand a wide range of temperatures necessary to cook foods like pork loin, eggs, and steaks.
After seasoning your cast iron pan with soybean oil, you can use almost any heat source that you have in your kitchen. Be it a campsite fire, regular oven, grill, stovetop, and natural gas.
Besides the seasoning function, soybean oil is an excellent option for cooking food. It has healthy fats, amino acids, and omega-3.
Coconut oil has gained popularity over the past decade due to its varied health benefits and fair prices.
It has a pleasant aroma and a slight flavor that is best for preparing delicious food. But does this mean coconut oil is best for seasoning on cast iron?
Well, coconut oil has a high smoking point and can be used to season cast iron pan. However, on the first seasoning, you should heat your pan to 350 degrees F before adding this oil. It has a relatively lower smoking point.
Coconut oil is the best option for a seasoning cast iron pan when you mostly cook at lower temperatures.
If you look forward to cooking with high temperatures, oil with a much higher smoking point will work for you, not this one.
Corn oil has a smoking point of 449 degrees F which makes it a good option when you want to cook food at high temperatures.
It has a high percentage of unsaturated fat, the main reason it bonds so well with cast iron for a durable seasoning.
Besides its s good seasoning properties, corn oil has many health benefits. This is the main reason it’s used all over the world for cooking.
Unlike other types of oil like olive, corn oil is cheap and can be easily accessed. Due to their low-price tags, people don’t often reuse them. This is important because reusing oil can cause health effects.
Animal Fats like butter and bacon grease
If you are in for a more saturated and natural seasoning oil, this oil is your best option. Animal fat seasons your cast iron naturally during regular cooking.
You don’t have to invest a lot of money into buying this oil neither do you need to apply multiple seasoning layers. It is effortless to find, efficient to use, and easy to apply.
A few downsides to expect with this oil include dark spots and streaks on your pan’s surface. This will make it uneven, and finally, your whole pan will turn very dark.
Purpose Made Cast Iron Seasoning
If you can’t easily decide what oil is best for your cast iron pan, you can simply use the cast iron seasoning oil.
Made from 100% plant-based and food-grade refined oil, the purpose-made cast iron seasoning oil is a great way to season, care for, and restore your cast iron pan.
It uses refined, solvent-less coconut oil that has a very light scent that won’t ruin your food flavors.
When used on a cast iron pan, this oil creates an effective non-stick seasoning that prevents the pan from absorbing moisture. It works best when applied to a clean and dry cast iron pan, washed with cast iron soap.
Unlike other seasoning oils, purpose-made cast iron seasoning doesn’t go rancid. It can last for a long time without going stale.
What Oil Not to Use
Generally, the higher the seasoning temperatures, the better the results. This means that the best seasoning oils with cast iron should higher smoking points.
Different oils have various smoking points, after which they start to produce smoke which may interfere with the taste of your food.
Particularly, the olive has a lower smoking point ranging between 325- and 375-degrees Fahrenheit.
Olive oil contains much oleic acid, antioxidants, and polyphenols, contributing to its stability and making it a healthy oil for cooking.
However, when it comes to seasoning casting iron with this oil, problems begin to arise. If you heat your pan beyond its smoking point, this seasoning starts to damage, wearing and tearing off, making your pan sticky. This will reduce the quality and taste of your food.
However, if it’s the only option available for seasoning your cast iron pan then choose specific types, including light and redefined olive oil.
These two types have a higher smoking point and will reduce the above challenges to a greater extent.
The ordinary types of olive oil are not the best type because you will have poor quality results if you don’t season your pan repeatedly.
This oil has a very high smoke point of 520 degrees F, which is both an advantage and a disadvantage.
The advantage of using avocado oil is that you will enjoy cooking your foods even at high temperatures after completing the seasoning. The chances of cooking foods that exceed 520 degrees F are minimal.
Moreover, avocado oil has more neutral flavors and has many nutrients that are beneficial to your health.
On the downside, this oil comes with relatively higher price tags compared to other types of oils.
Moreover, the whole process of seasoning a cast iron with avocado oil is way too risky.
You have to heat your pan to very high temperatures, leading to severe burns if not handled with care. Even pouring oil over a pan such hot increases the risks.
Besides those risks, this oil is the best with a serious kitchen with high standard equipment, cast iron included.
If you feel you must use this oil at your home, you must not be discouraged by the risks. Only you have to handle everything with care during seasoning.
If you do it successfully, you will get the best cooking experience for a long time without worrying about rust or rough surface.
