Oil to Season Cast Iron Skillet Buying Guide
Flaxseed is the most common source for the majority of these oils for seasoning cast iron. One of the reasons behind its high demand is it being among the only edible drying oils to exist. This means it dries up or hardens over time when exposed to air through polymerization.
Unfortunately, these oils are usually more expensive than other seasoning oil variations and also less accessible. For purchasing offline, you may need to search in health food stores or pharmacies to find it.
Another issue with flaxseed oils is their unpleasant odor which can easily make you discontinue using it after a while.
Grapeseed is considered by many as the best oil for seasoning cast iron skillet. Along with a high smoke point, it comes at very affordable price points and is easily accessible at the usual grocery stores. It can ensure a long-lasting seasoning for your cast iron cookware and thus improve its lifespan.
This durable oil has a neutral color which can be included in the preparation of many kinds of dishes.
You can use it to fry, roast, sear or sauté ingredients, as well as to make salad dressings. Remember that it has a light flavor which can add to the overall taste of that dish.
c. Coconut Oil
This oil is supremely popular among people for a myriad of reasons. Its high-fat content makes coconut oil a great choice for low-carb diets like keto and it helps to reduce protein loss for your hair. However, it may not be the most fruitful choice in the seasoning because of its high ratio of saturated fats.
This ratio suggests that it cannot form bonds properly leading to unsuccessful polymerization. As a result, the coating established on your cast iron skillet will end up weak and useless. However, some brands have found a way to resolve this issue with a specialized formulation.
d. Soybean Oil
Along with seasoning your cast iron cookware, this oil can also be used to prepare a wide range of dishes. You can take its help while cooking something as simple as eggs in the morning, or a much more sophisticated dish like steak or pork loin! It can also be a good source of healthy fats for your family.
e. Avocado Oil
One of the main reasons behind the rising popularity of avocado oil for cast iron seasoning is its incredibly high smoke point. So it can be used for searing, frying, roasting, as well as salad dressings!
Additionally, avocado is a common favorite in all kinds of healthy diets since it is full of antioxidants and useful fats.
If any of these don’t fit your requirements, there are many other kinds of oils you can check out for seasoning your cast iron skillet.
Among them the notable options would be palm oil, sesame oil, corn oil, sunflower oil and olive oil. These can be found easily in any typical grocery shop.
2. Smoke Point
Smoke point is the temperature at which your seasoning oil will not stay on the skillet surface anymore and start to polymerize into the material.
Needless to say, a good seasoning oil for cast iron needs to have a high enough smoke point to not cause such issues during daily cooking routines.
Flaxseed fails in this aspect since its smoke point is only around 225°F which is not at all enough for cooking all kinds of dishes.
However, grapeseed shines here with a high smoke point of 420°F. The highest temperature however belongs to avocado oil that can stay on the cast iron surface up to 520-570°F!
Apart from these, other common options are soybean oil (450°F), sesame oil (450°F) and olive oil (228-323°F).
3. Health Benefits
Oils in general are mostly known for their fat content. Even though it is a detested nutrient in many low-fat diets, the rise of low-carb diets has rebranded it as a very beneficial element if used in the right way.
The fat composition of all these oils can be divided into three categories - polyunsaturated, monounsaturated and saturated.
Typically, the first two are considered to be good since they lower the risk of many diseases. Saturated fats can be bad by increasing cholesterol and deteriorating heart conditions.
Here is a chart so that you can check out the different distributions of fats in several seasoning oils at a glance:
Some seasoning oils have a flavor of their own which can add to the dishes, while some come with no additional flavor. The latter will be a better fit for those who don’t like any new flavor in their dishes.
However, if you do want an extra kick in the taste, you can use any oil except avocado, sesame, olive, coconut and flaxseed.
Tips To Keep Clean And Take Care Of Your Cast Iron Skillet
The First Wash
When you first get the brand new cast iron skillet in your hand, the wash needs to be a little different from the regular ones.
Usually you should not use soapy water on them but it is an important step for the first wash. Mix a bit of soap into some hot or warm water and then use it to eliminate factory residue.
It is safer to use relatively softer utensils made of rubber, silicone or wood. The metal ones can be used occasionally but their contact with the skillet surface needs to be at a minimum. You need to keep them away specifically when you are laying down the seasoning.
Cleaning After Cooking
Often there are food particles stuck on the surface of skillets. For those made from cast iron, remember to use warm water to rinse the skillet first. Then take a gentle brush or a griddle scraper to get rid of particles.
If they are still stuck, prepare a mixture of canola oil and kosher salt with 3-5 tablespoons of each. Dip a paper towel into it and then scrub your skillet’s surface with this towel.
Limited Use Of Water
Of course long and continuous exposure to water can cause rust over time on cast iron. However, that doesn’t mean you need to completely remove water from the cleaning of these skillets.
You do need to rinse it with warm water before cleaning and soak it for a few minutes in warm water occasionally. Just remember to follow it up by drying the cookware perfectly.
The water needs to be warm or hot because cold water on a cast iron skillet can warm the material.
On the other hand, washing a cooled-down skillet can be hard because the particles stuck on it may get dried up and thus tougher to remove.
Needless to say that your cast iron skillet should be stored in a dry place since long contact with water can easily result in rust. For the same reason, make sure the skillet has been dried off fully.
It would be better if you don’t stack them over one another. But if you have to do so for the lack of space, make sure to place a single paper towel on each of their surfaces.
Frequently Asked Questions
Is It Okay To Cook Tomato Sauce On A Cast Iron Skillet?
It is a common idea that cooking any dish involving a tomato can be harmful to a cast iron skillet.
Because of its acidic properties, tomato is capable of eating away the seasoning you so carefully put there. However, you can still cook tomato sauce in it occasionally with the help of really good seasoning.
As long as the pan is well-seasoned and you are not cooking acidic foods in it every day or every week, it should be fine.
How Often Do You Season A Cast Iron Skillet?
The seasoning will need to be more often if you cook with it frequently. Besides, if your diet or your family requires you to cook with many acidic foods regularly, you may have to season it more regularly than others. If not done so, the acidity will gnaw at your cast iron surface and ruin its purpose.
Does Cast Iron Heat Evenly?
Even though it often may seem like it, cast iron doesn’t ensure even heat distribution. However, it does retain a lot of heat which then manages to cook the dish easily.
To see it for yourself, you can use a laser thermometer to measure the temperature in multiple areas of your hot cast iron skillet.
Why Is My Cast Iron Seasoning Sticky?
If you notice that the cast iron surface has become sticky right after applying the seasoning, it means too much oil has been applied.
The delivered amount was higher than the required amount. Another possibility is the oil has a high content of saturated fat which prevents forming a strong bond.
It might be overwhelming to find the best oil to season cast iron skillet from so many varieties produced by so many reputable brands.
But that is where our detailed discussions on this matter can help you! Now you know which factors to keep in mind while checking out this versatile array of seasoning oils.
The most beneficial one is grapeseed but flaxseed and avocado are also good options. However, if you are a fan of steaks and fries, you will need a much higher smoke point than what flaxseed can put up with.
Besides, the presence of additional flavor and the amount you are getting in each unit plays a role in your final decision as well.
So begin your hunt for the right cast iron seasoning oil today!
