Top 5 Oils for Seasoning Cast Iron

 

We all have a cast iron pan in our homes that is passed on from generation to generation, holding extremely sacred value for the entire family. Well, while the concept may sound ridiculous to some, the iron actually has the capacity to last long enough which means you can easily clean it and keep it in up-to-date condition to be used for years. If you have been using a cast iron pan for your meals, then it is no secret that you need to season it properly before you impress everyone with your cooking skills.

Whenever you have to use the pan, you need to make sure that the pan is seasoned enough to give you the expected results. There has been a lot of debate among people and experts alike about the best oil for seasoning cast iron. You have numerous options for application but if your pan is new and requires some great maintenance, we understand your reluctance to experiment. You need the best oil for cast iron that can prevent the material from rusting so when you take it out for a new meal again, it feels as good as new.

Lots of people expect a very straightforward answer with this one but again, there are so many options in the market that makes it difficult to just pick one, in fact, most of those come with qualities of their own so it all comes down to what you want. Regardless, we have sorted out the list for you to make it easier to choose the best oil to season cast iron. All you have to do is read through the properties and see which one suits you the best to answer the ultimate question: what oil to season cast iron with?

What is Seasoning?

If you ask this question to someone who is passionate quicker, chances are that they will consider it a blasphemous remark as far as the cooking law is concerned. However, we are open to all newbies who want to learn. This is why before you pick the best oil for cast iron seasoning, you need to understand what the process is and how you carry it out. Before you put any type of cooking material in the pan, you have to apply a thin layer of any cooking oil on the surface. Once you do this, you will notice that the tiny pores that are present in pots and pans begin to fill with that oil, and raising the temperature causes them to heat up. This type of preparation is only needed for cast iron because you have to list food off of it when you are cooking. Non-stick and steel cookware doesn’t require any such thing because the material is sufficient enough. However, the taste that the food made in cast iron brings is obviously loved by everyone and so we go through all these efforts to prepare the best meal of the season.

Many companies claim that they already season the cast iron before selling the pots and skillets to you and while that may be true, we still recommend that you take matters into your hands and season the cookware. It ensures that the cast iron lasts for a long time and just like your parents and elders, you too can pass it down from generation to generation.

Why Does Cast Iron Require Seasoning?

We have already told you that you need to lift food off of the skillet and pans while you are cooking which means that seasoning makes the job easier. However, there is a lot more to the process. Scientifically speaking, you are polymerizing the cookware so that the oils are absorbed into the material, making it extremely easy to work with. The ultimate goal is to make it extremely slick so your food can glide on it. When kept away for a long time (because no one cooks in cast iron every day), the material tends to get rough, and even rusting might appear. You have to be careful while buying all cast iron cookware but when it comes to seasoning, you have to pick the best-cast iron seasoning oil and fill the pores that form on the surface. You leave it to simmer to an ideal temperature and after the surface looks visibly better and smoother, you get to work. Now, your food wouldn’t stick to the pan and you will be done with the work in far less time. Again, it is quite effective against rusting as well so if you use them without seasoning, be prepared to taste the worst food of your life.

Now that we have established why it is one of the most important kitchen hacks, let’s directly go to the list and see why you need to be quite vigilant about selecting the oil and which is the best option in the market right now. Our experts have chosen and compiled the list after testing them thoroughly so you won't have to go through the entire hassle. Just remember that whichever one you pick works great for the type of skillet and pan you have and can take care of the pores that accumulate in their overtime. We swear that after going through the list, your parents and grandparents would be impressed with your knowledge and the guests would love the food you prepare for them. It is time for summer, after all and only a month is left till the pool parties come back in full flow.

1. All-Rounder Winner: Grapeseed Oil

Best Review

This is one of the oils that is recommended the most for seasoning and it has garnered the attention of the customers as well. If you go on Google and search for the solution for cast iron, this is the first option that would show. It could be because from your next-door neighbor to professional chefs, people are quite fond of using grapeseed oil for seasoning cast iron. The reason behind that is the high smoke point it carries. What this means is that you can simmer the oil for a long time on the skillet and the pan will not leave that burning smell behind. In fact, it will quickly soak it up in the pores, making the job extremely easy for you. Even with the flavor, lots of people are worried that it might reflect in the food but grapeseed comes without any artificially overwhelming aroma and the flavor is also very neutral. So when you are starting fresh, we definitely recommend that you use grapeseed oil for it.

Use: La Tourangelle Grapeseed Oil

Reason to Buy

  • Smoke point goes as high as 430 F
  • No burning
  • Mild flavors
  • Blends well
  • Inexpensive
  • Neutral smell
  • Healthy

Reason to Avoid

  • The cold-pressed varieties might have a low smoke point

2. Recommended by the Experts: Flaxseed Oil

Best Review

What makes flaxseed oil different than the other ones is that it was not the typical choice a few years ago. In fact, a famous blogger who is passionate about cooking wrote about their experience with the oil and that sort of shook the entire industry. They realized that this too could be a healthy option for seasoning and began to use flaxseed oil in the cast iron cookware. The results were quite positively encouraging and now lots of people use this oil in the skillets before they get to cooking. The only downside you might experience here is that flaxseed oil comes with a low smoke point so blending it with the cookware might not be as convenient. But where it lacks in one feature, you will see that once you begin to leave the material with this variety, the food will automatically start tasting better. You just have to season it 6 times for 1 hour and the temperature has to remain low. It is not very easy to find and some people think that since you have to season the pan multiple times with flaxseed, it might not be a very economical option either.

Reason to Buy

  • Makes surface harder
  • Smooth cooking experience
  • Better than vegetable oils
  • No wear and tear with the oil

Reason to Avoid

  • Expensive
  • Requires multiple seasoning
  • Not available easily
  • Low some point
  • Strong smell

3. Best Hardened Coat: Avocado Oil

Best Review

Oils that have a high smoke point are just amazing because you don’t have to monitor the flame and can quickly get done with the job without wasting hours on it. The point for this one stands at a stellar 520F and while many people consider this great, some experts have shown their reservations. When it comes to health, no option is better than avocado oil because it is neutral-flavored so none of the taste can be felt in the food. However, being the healthier option also makes it somewhat expensive as compared to the other options on the list. If you are too sensitive about your cast iron cookware, we suggest that you use this oil because it smoothens the surface and fills the pore, making sure the skillet or the pan remains in your use for the longest time. The only problem that some people have with a high smoke point is that taking it up to 500 F can be quite dangerous for the pan itself. Plus, it is oil after all and even a little bit of negligence can result in big disasters. 

Reason to Buy

  • High unsaturated fats
  • It Helps oxidizes and polymerize
  • Tough coat of seasoning
  • High smoke point
  • Long shelf-life
  • Doesn’t go rancid quickly

Reason to Avoid

  • Expensive
  • High smoke point can be dangerous

4. Best Affordable: Canola Oil

Best Review

Health buffs know how important olive oil is. Not only is it a better option for keeping your organs pure and clean but it also doesn't build up any fat. Usually, every house has a bottle of olive oil in the house but did you know that it is the best oil to use to season cast iron? Even though it is not expensive, cooks only make vegetables in olive oil but that doesn't mean the taste isn't loved by everyone. That eliminates the flavor being too much and the aroma is quite pleasant too. The only downside that people have experienced is that it has a low smoke point. So, again you need to simmer and season it for quite some time to let the oil fill the pores and make your cookware better. You can also use a thermometer or even an oven to set the temperature because it is very easy to go overboard with the olive oil and you don't want to harm the cast iron. As per our experts, 375 F works great for all kinds of pans and skillets. It is necessary to let your cookware develop a bond with the oil, no matter which one you are using or all your efforts would be quite futile.

Reason to Buy

  • Inexpensive
  • Soft smell
  • Delicious flavor
  • Healthy
  • Spreads easily

Reason to Avoid

  • Low smoke point
  • Harmful on high flames
