Olive oil is a popular choice for seasoning iron cookware, but there are other types of oil you can use. Avocado oil has a higher smoke point and similar saturated fat content to olive oil.
Best Oil For Seasoning Iron Cookware:Avocado oil is also suitable for use on the grill or in salad dressings. Ghee, also known as clarified butter, is another oil you can use for seasoning. Ghee contains over 50% saturated fat but has a neutral flavor. It also tends to last longer in the pan than olive oil.
Best Oil For Seasoning Iron Cookware
I just bought a new nonstick Teflon skillet. The nonstick layer of my old one was beginning to scrape off, and I was starting to find little black specks in my food. No bueno! Even though I only used silicone utensils in the skillet, and I took care to not clean it with harsh scrubbers, my nonstick skillet only lasted me about 1 year of heavy use.
My cast iron skillets, on the other hand, are like fine wine… they get better with age!
The oldest piece in my cast iron collection is a Griswold cast-iron skillet (which I recently restored here), and at about 85 years old, it’s still going strong.
You see, that’s one of the major benefits of cast iron cookware… if properly maintained and seasoned, a good piece of cast iron should last generations. In 50 years, your grandkids could be using the same cast iron pan that you used this morning to make breakfast, as long as you know the best oil for seasoning cast iron and the appropriate seasoning method to choose .
But first, let’s talk about WHY seasoning cast iron is so important:
What is “Seasoning” on Cast Iron?
The “seasoning” on cast iron refers to the layer (or layers) of baked-on oil or fat that protect your skillet and create a nonstick surface.
Many cast iron skillets that you purchase (like those from Lodge) will come pre-seasoned, meaning that the manufacturer has put the pan through the seasoning process, so there is at least one layer of seasoning already baked on the pan. But, for optimal performance, you should still season your brand new cast iron pans before cooking with them.
The Science Behind Cast Iron Seasoning
The actual “seasoning” on your cast iron cookware is developed through a process called polymerization. Polymerization occurs when the right oil or fat is heated in a pan at high enough temperatures to form a hard black surface on your pan.
Certain fats are better for polymerization, which is why it’s important to choose the right oil for seasoning your cast iron.
Why is Seasoning Cast Iron Important?
Before we get into the best oil for seasoning cast iron, let’s talk about WHY the seasoning process is so important.
The whole purpose of seasoning cast iron is to protect the surface of the cast iron piece from rust, and to make it become nonstick and versatile. A properly seasoned cast iron pan can be used to bake a cake, sear a steak, and make the best over easy eggs, and you shouldn’t need to do any sort of scraping to remove stuck-on food afterwards.
Seasoning cast iron can also save you money! Unlike Teflon or other nonstick pans, the surface of your cast iron can be “fixed” so that you don’t need to buy a new pan every time that your seasoning scrapes off. The seasoning on cast iron is renewable, meaning that when your pan starts to develop spots where your food sticks, you can just apply a fresh layer of seasoning to extend the life of the pan.
What Makes a Great Cast Iron Seasoning Oil?
When choosing an oil to season cast iron, there are a few factors that you need to consider:
High Smoke Point
An oil’s smoke point is important, because that 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, so you need an oil with a high smoke point to withstand those temperatures.
Also, if you cook at high temperatures, like for instance when you sear the perfect steak in your cast iron skillet, you will want to use a seasoning oil with a higher smoke point.
A good rule of thumb is to always choose a seasoning oil with a higher smoke point than the temperatures that you will be using for cooking. For instance, if you’ll be using your skillet to sear at a temp of 400 degrees, don’t choose an olive oil with a smoke point of 350 degrees to season your skillet.
Higher Concentration of Unsaturated Fat
Unsaturated fats have a chemical makeup that is more optimal for polymerization, the process that needs to occur to develop the perfect cast iron seasoning. So steer clear of oils with a higher concentration of saturated fats, like coconut oil and palm oil.
You don’t want the food that you are cooking in your cast-iron skillet to take on the flavor of the oil you used for seasoning, so look for an oil that is neutral in flavor.
Also, a neutral flavor oil is going to be more versatile. So instead of spending money on an oil that can only be used for one purpose, you can buy a good multipurpose neutral flavor oil that can be used for making salad dressings, sautéing vegetables, AND seasoning your cast iron. To me, that’s bang for your buck.
You don’t need to spend a fortune to buy a good cast iron seasoning oil. In fact, my two favorites are less than $9 for 16 ounces. And if you use your cast iron cookware frequently, then you’ll probably want a more affordable seasoning oil.
What Cast Iron Seasoning Oil Do the Manufacturers Recommend?
There are 4 main cast iron cookware manufacturers, and their recommendations for the best oil to season cast iron are pretty similar. Let’s take a look:
|Cast Iron Manufacturer||Recommended Seasoning Oil|
|Field Company||“We recommend using grape seed oil for oven seasoning.”|
|Lodge Cast Iron||“Based on availability, affordability, effectiveness, and having a high smoke point, Lodge recommends vegetable oil, melted shortening, or canola oil.”|
|Smithey Ironware||“We use a pure grape seed oil to season our skillets. However, any off-the-shelf vegetable oil or shortening will do just fine as a seasoning oil.“|
|Stargazer Cast Iron||“We recommend using an oil with a high smoke point such as canola, grape seed or sunflower.”|
So, as you can see, the general consensus is grape seed oil, but overall the smoke point of the oil and the types of fats they contain are the most important factor when choosing the best oil for seasoning cast iron. You can go here to read more about different cooking oils and their smoke points.
The BEST Oil for Seasoning Cast Iron – My Favorites!
Smoke point: 500-520 degrees
I’m listing avocado oil FIRST, because it is the best oil for seasoning cast iron, in my opinion! Just be sure to look for a refined avocado oil, because the smoke point will be much higher (around 500-520 degrees) than an unrefined version.
The avocado oil that I have been using for YEARS is by Better Body Foods, and it has a smoke point of 500 degrees. I get it on Amazon for about $8.00 per bottle, so it is a fairly good value.
I also prefer the avocado oil for seasoning cast iron because of its versatility. I don’t like to spend money on cooking products that only have ONE use, and avocado oil is neutral in flavor and a healthier oil, so I use it in all of my cooking. I even use it to season and maintain my Camp Chef flat top grill.
Crisco Solid Shortening
Smoke point: 490 degrees
Crisco solid shortening is a popular cast iron seasoning oil because it is versatile, affordable, and widely available in grocery stores. The solid Crisco shortening (the kind that comes in a metal tub) also has a high smoke point of 490 degrees.
When I first started out with cast iron, I used Crisco exclusively to season my pans, and it worked great. I only made the switch to avocado oil because of the health benefits and versatility. But if you’re looking for the best AND cheapest oil for cast iron seasoning, then you can’t go wrong with Crisco.
Grape Seed Oil vs. Avocado Oil
As mentioned above, 3 out of the 4 cast iron manufacturers recommend grape seed oil…. so why do I prefer avocado oil? Let’s take a look at the chemical compounds and health benefits of each:
|Oil Characteristics||Avocado Oil||Grape Seed Oil|
|Smoke Point (refined versions)||520 degrees||420 degrees|
|Fatty Acid Composition:|
|Average Price Per Oz||$0.40/oz||$0.25/oz|
In recent years, the health benefits and effects of heating grape seed oil have come into question.
Grape seed oil has been touted as a “healthy oil” for years because of its high levels of omega fats. However, some grape seed oils may also contain “potentially harmful levels of polycyclic aromatic hydrocarbons (PAHs), which are known to cause cancer in animals.” (Healthline.com)
Overall, research on the effects of grape seed oil on your health is lacking, so you’ll need to form your own educated opinion on this one.
As you can see from the table above, the main difference between avocado and grape seed oil is the fatty acid composition. Grape seed oil contains a high concentration of polyunsaturated fat, while avocado oil has a higher concentration of monounsaturated fat… but why does that matter?
It all comes down to the degradation when heated.
Polyunsaturated fats like those found in grape seed oil have been found to produce toxic compounds (including those that cause cancer) when heated. Saturated and monounsaturated fats, on the other hand, are more resistant to heat degradation.
Both oils contain a high concentration of unsaturated fats, which are better for polymerization than saturated fats, but given that the jury is still out on heating polyunsaturated fats, I’ll just stick with my trusty avocado oil.
Bottom line, you use your own judgement when choosing the best cast iron seasoning oil for you.
Other Fats and Oils for Seasoning Cast Iron
While avocado oil and Crisco are my favorites, it all comes down to personal preference. In fact, opinions on which oil to use are as varied as the oil choices themselves. One cast iron fanatic will tell you to only use bacon fat (and why you’re dead wrong if you don’t!), while another “guru” will swear by flaxseed oil and shun anyone that thinks differently. Ultimately, it all comes down to what works best for you.
Here are some other popular oils for seasoning cast iron:
Vegetable and Canola Oil
Smoke point: 400-450 degrees
We only use vegetable and canola oils for deep frying and baking cakes and brownies, but many people use these oils to season cast iron. Even Lodge’s own Seasoning Spray Oil is made of 100% canola oil. The relatively low price and decent smoke points of these oils make them popular choices, but there are better seasoning oils out there, in my opinion.
Smoke point: 225 degrees
Flaxseed oil may be recommended by some cast iron “gurus” because it is considered a “drying oil”, meaning that it “dries hard” to cast iron, but I would not recommend it for seasoning.
First, it’s on the expensive side. Second, the more widely available unrefined version has an extremely low smoke point. Third, you have to be careful to choose the correct variety, as many people complain that certain flaxseed oils will flake off after seasoning. You definitely don’t want to go through the multistep process of seasoning your cast iron pan only to have all of that hard work just flake off, so this oil is low on my list.
Smoke point: 465 degrees for light/refined, 325-375 degrees for extra virgin
Olive oil is another popular choice for seasoning cast iron because most people probably already have it in their pantry. However, extra virgin olive oil has a relatively low smoke point, so heating it to higher temperatures will cause it to break down and turn rancid. If you are going to use olive oil, look for a light or refined version, but there are still better options.
Olive oil may be great for making salad dressings, but I would NOT recommend it for seasoning cast iron.
Bacon Fat and Lard
Smoke point: about 370-375 degrees
Bacon fat and lard have been used for seasoning cast iron for decades, probably because that was the only thing available. When our great grandparents were cooking with cast iron, they couldn’t just go out to their backyard and pick a dozen avocados to expel oil from. And they definitely couldn’t just add a bottle of specialty oil to their Amazon cart.
So animal fat was king. And while there’s nothing wrong with using bacon fat and lard for seasoning cast iron, it was widely used by chuckwagon cooks for decades, the high levels of saturated fats do not create the optimal conditions for polymerization. Plus, modern technologies have brought us much better options.
What NOT to Use for Cast Iron Seasoning
While the popularity of coconut oil is on the rise because of its health benefits, it should NOT be used for cast iron seasoning. Coconut oil has a super high concentration of saturated fats, making it difficult for the polymerization process to occur. In fact, if you choose to use coconut oil, you will probably find that your seasoning will not be near as durable as other oils.
Bottom line, use coconut oil to moisturize your skin, NOT to season your skillet.
Every household probably has butter, and you can even buy it in some gas stations. But just because it’s readily available and cheap, doesn’t mean that you want to season your cast iron with it.
Butter is high in saturated fats, which remember are not as good for the polymerization process, and it burns at about 250-300 degrees. In fact, how many times have you heard someone say that if you’re going to cook with butter in your skillet, then you also need to add some oil to raise the smoke point and prevent the butter from burning. Case closed.
Best Oil For Seasoning iron Pan
When you’re looking to season your iron pan, there are many different oils you can use. While some are better than others, the ones you use for seasoning are largely dependent on your individual preference. For example, flaxseed oil is a popular choice, but it can be expensive and has a low smoke point. You also need to be sure that you buy the right variety. Additionally, it can flake off after seasoning.
The best oil for seasoning iron pan is based on the type of metal you have. Safflower, grapeseed, and flaxseed oils are all good options, but avoid saturated fats. Saturated fats will not bond well with cast iron, so they won’t work as well. Use a higher percentage of unsaturated fats when seasoning, such as flaxseed or grapeseed oil.
Olive oil is another great option, but it doesn’t have the same health benefits as olive oil. If you want to use olive oil to season your pan, make sure it has a high smoke point of at least 375 degrees Fahrenheit. If you’re not sure, use a thermometer to ensure the temperature is correct. The oil needs to be at the right temperature for it to bond to the iron. Otherwise, it won’t be able to bond with the metal and will break off.
Olive oil is another popular option for seasoning iron pan. Olive oil is highly beneficial for the skin and contains many healthy fats. Olive oil has a strong flavor and is hard to remove after cooking. Coconut oil, on the other hand, is neutral in flavor and can be used in a wide variety of ways. However, olive oil may be too greasy for cast iron pans. In such cases, you can use grapeseed oil.
Best Oil For Seasoning Cast Iron
Depending on your taste, avocado oil can be an excellent choice for seasoning cast iron cookware. Not only is it a healthy fat source, but it can also be used to cook a wide variety of dishes, from steak to pork loin. In addition to its versatility, avocado oil is also a healthy fat source and has a high smoke point. It is also full of antioxidants and useful fats. Read on for some of the best avocado oils and their benefits.
Coconut oil is another popular choice. Its high fat content makes it ideal for people on a low-carb diet. It also helps reduce protein loss from hair. The downside of coconut oil is that it has a high saturated fat content, which leads to a weak polymerization process. As a result, the coating of a cast-iron skillet is likely to remain weak. But some brands have specialized formulas to solve this problem.
If you’re wondering which oil is the best choice for seasoning cast iron, you’ll need to know what smoke point it has. The higher the smoke point, the better. Oils with high smoke points are less likely to burn. A frying pan coated with oil will end up with an unpleasant taste. The smoke point of an oil will be lower if the oil is refined. This oil is often used in stir-frying and Asian cuisines and has a low smoke point. While it is a cheap option, it isn’t recommended for seasoning cast iron.
Best Oil For Seasoning Carbon Steel
The Best Oil For Seasoning Carbon Steel Pans is one of the most important aspects of steel cooking. This type of steel is naturally chemical-free, and artificial ingredients will compromise the purity of the metal. To ensure the best results, you should look for organic and flaxseed oil. This oil is rich in antioxidants and healthy fats, and it is also an excellent choice for seasoning carbon steel pans. The oil’s high smoke point of 519 deg F makes it ideal for searing foods at high temperatures.
The first step is to clean the carbon steel pan, removing the protective layer or factory preservation oil. Next, the carbon steel pan must be allowed to air-dry. Once completely dry, the carbon steel pan should be seasoned by spreading coconut oil over its entire surface. Heat the pan on low-medium heat until the oil starts to smoke, then repeat the process a few times. After a few minutes, the pan should have a brownish color.
Another way to season-carbon steel pans is to heat it in the oven. To do this, coat the carbon-steel pan with oil and place it in the oven. Preheat the oven to 400 degrees Fahrenheit and place the pan on the baking sheet. Allow the pan to heat for 10 minutes. Be sure to check the pan’s safety label before using it. It is important to make sure it is oven-safe so you do not risk contaminating your food with melted oil.
Coconut Oil For Seasoning Cast Iron
To season cast iron, you can apply a layer of coconut oil to the surface. The coconut oil must be heated to the smoke point, but should not exceed it. The higher the temperature, the more likely the coconut oil will become carbonized. Food cooked at high temperatures will break down the layer of oil, reducing the non-stick properties of the pan. If you use coconut oil regularly, it will work well in seasoning cast iron.
Virgin and cold-pressed canola oil have lower smoke points, making them less suitable for seasoning cast iron. While canola oil is cheap and convenient in many recipes, it is not optimal for cast iron seasoning. Other oils that work well with cast iron, such as flaxseed oil and grapeseed oil, have lower smoke points and higher saturated fat content. They’re both neutral in taste and smoke points well above 400 degrees, and are also good for cooking.
Once the cast iron pan has been cleaned, apply the coconut oil on the entire surface, covering the sides and the walls. Place the pan upside down on a baking sheet and then place it in the oven for about an hour. Leave it in there until it becomes fully pliable. Once it is completely cooled, it is ready to use. After that, you’ll be cooking in your new pan! Just remember to follow the instructions on the container!
Sunflower Oil For Seasoning Cast Iron
For seasoning cast iron, many people choose olive oil. It is inexpensive and high in monounsaturated fat. However, it doesn’t have the same smoke point as olive oil, which makes it unsuitable for cooking. Olive oil is not only low in saturated fat, but it also has a great flavor and aroma. It is also easy to find, and it won’t break the bank. Besides, it will help you cook healthier dishes without compromising the taste or aroma.
The most common reason why people season their cast iron is to reduce the amount of carbon in the metal. By seasoning, the metal can retain its natural cooking surface for longer. As a result, foods cooked in cast iron will pick up the flavors and textures of the seasoning. However, foods high in acids will wear off the seasoning faster. Fortunately, there are a number of ways to keep the surface of your cast iron looking and performing its best.
Once you’ve finished seasoning, you can either bake your cast iron. This step is recommended if you’re short on time. A new pan will get re-seasoned after regular use, so don’t skip it! You can also choose to season your pan with a different oil if you prefer a different flavor. The choice is completely up to you. Soak the cast iron in kosher salt for 30 minutes before rubbing it with sunflower oil.
Worst Oil For Seasoning Cast Iron
There are several different methods for seasoning cast iron, including vegetable oil and animal fat. Some people recommend lard or vegetable oil, while others recommend olive oil or corn oil. Other people recommend using bacon drippings or butter, which both contain saturated fat. But the truth is that you should use a combination of both. So which one is right for you? This article will examine the differences and give you tips for seasoning cast iron.
Olive oil isn’t suitable for seasoning a cast iron pan, and neither is butter. Butter doesn’t season iron properly and is a natural fat, so it isn’t the best option. The worst oil for seasoning cast iron is grapeseed, canola, vegetable, or corn oil. All these types of oil have a lower smoke point than olive oil. They also don’t have the same flavor as olive oil, and they smell horrible.
Linseed oil is a high-quality plant fat that is a great choice for seasoning cast iron. Its high percentage of unsaturated fat prevents oxidation and helps the oil remain fresh for longer. And unlike olive oil, it doesn’t break down quickly. So if you’re looking for an oil to season your cast iron, you should choose something with a high omega-3 content.
Olive oil is another popular option for seasoning cast iron. However, olive oil has a low smoke point, which means it will burn quickly and easily at high temperatures. The oil will also become rancid if it’s exposed to higher temperatures. A lighter, refined olive oil is better. Olive oil is also good for salad dressings, but not for seasoning cast iron. You should also use vegetable oil to season your cast iron frying pan.
Avocado Oil For Seasoning Cast Iron
If you’ve ever wondered if you should use Avocado Oil For Seasoning Cast Iron, you’ve come to the right place. Unlike other oils, avocado oil has a low smoke point and can withstand high temperatures without changing the taste of food. However, if you’re not sure about how to use it, here are some tips. You can also use a vegetable oil instead of avocado oil, which is more readily available.
The first step is to rub some oil on the cast iron utensils with a clean paper towel or lint-free cloth. Then, allow the cast iron utensil to sit overnight or for at least four hours before washing it. Then, use a clean paper towel or rag to wipe the remaining oil from the pan. Repeat the process for two consecutive days. This way, your cast iron pan will stay in perfect condition.
Once you’ve finished the scrubbing, apply some avocado oil to the entire pan. Use a paper towel to spread the avocado oil evenly over the surface. Leave the pan for an hour to let the avocado oil get into the pores. Once the cast iron pan has cooled, it’s ready for the next step: seasoning. Avocado oil is one of the most popular oils for seasoning cast iron. It has a higher smoke point than Crisco solid shortening, so you’ll want to be careful about spreading it too thinly.
As with any cooking oil, there are pros and cons to both. Use the right one for you. Avocado oil is a healthy fat that prevents food from sticking. Avocado oil is a good choice for seasoning cast iron since it has a high smoke point, which means it won’t burn your food or your pan. Just make sure you use a high-quality avocado oil. You’ll be glad you did.
In conclusion, oil and cast iron cookware go together like peanut butter and jelly… you can’t have one without the other. And since selecting the right oil is such an important part of the cast iron seasoning process, you need to do your research.
Science tells us to look for oils with higher concentrations of unsaturated fats and high smoke points. I personally have had great success with avocado oil and Crisco solid shortening, but the choice is yours. Just be sure to apply very thin layers of whichever oil you choose, and heat your pan past the oil’s smoke point.
