Uncertainty about Seasoning Cast Iron

Many of us think seasoning is complicated. But, the truth is it is way simpler than your think. We’ll tell you the best ways to season cast iron below. The most practiced way is to season with vegetable oil.

Solution?

Coat the cast iron pan with a thin layer of vegetable oil. Place the pan upside down in an oven at 350o for an hour. Don’t forget to put a foil under the rack to grab any excess drips.

Turn off the oven and leave it inside until it is cooled down. After it has returned to room temperature, coat the inside of the pan with a small amount of oil. Thus, your cast iron pan will remain lubricated and well-seasoned.

Food Sticks to the Cast Iron Pan

Many people indeed encounter the issue of food sticking with cast iron. You may wonder, why is my cast iron sticky? Well, this happens when the cast iron cookware is not seasoned correctly.

But sometimes, you may still encounter cast iron sticky after seasoning the cookware correctly. The possible reason could be the lack of fat used while cooking or cooking with high sugar content.

Solution?

Scrub out all of the burnt or stuck using the rough side of a sponge. After the cast iron skillet sticky residue is removed, clean and dry it thoroughly. Then re-season it.

Rust on the Surface of the Pan

Sometimes old cast iron pans have rust on the surface. It happens if there are any cast iron pan sticky remains for a long time. Sometimes rust accumulates when you don’t dry the pan correctly. Also, it forms when the pan is exposed to moisture for a long time.

Solution?

If there is slight rust, you can scrub the rusted area using steel wool. Or a soapy scrub pad would remove the rust. However, if the rust is super old, soak the pan in vinegar for at least one hour. By then, the rust will be gone by itself.

After the rust is removed, dry the pan thoroughly. Season the pan and repeat the seasoning process on the rusted part.

Some MYTHS about Cast Iron Seasoning

There are different opinions as well as myths when it comes to seasoning cast iron cookware. First of all, many have claimed using vegetable oil for seasoning is a bad practice. They think it severely harms the surface of the cast iron pan.

So, you need to know that it’s an absolute misconception. There is nothing wrong with using vegetable oil. In fact, it contributes to seasoning every time you cook. Cooking with vegetable oil further accelerates the seasoning process.

Then, some people think not removing the excess oil can lead to uneven cast iron seasoning issues. It doesn’t matter if there is any extra oil remains on the pan. When you keep the pan with oil in an oven, the oil heats up and runs more quickly.

In the meantime, the oil doesn’t get a chance to bond with the iron. This leaves spots on the pan without seasoning. These spots will be sticky sometimes. How to fix it? Simply repeat the process until the surface of the cast iron pan is thoroughly seasoned.

How to Prevent Uneven Seasoning Cast Iron Issues?

An uneven seasoning issue on cast iron is really annoying. You may have given your best to season it properly. Chances are, you’ve tried everything, but nothing seems to work.

Even after seasoning the pan many times, the surface still has an uneven finish. The food sticks, and it results in cast iron seasoning splotchy. Good luck that you have finally come to the right place.

Below we’ll discuss different methods of seasoning cast iron cookware. You can quickly season your cast iron cookware with some things available in the kitchen. Follow the solutions below and eradicate the uneven seasoning cast iron issue.

1. Season with Flax Seed Oil

Flaxseed oil is mainly known for its health benefits. As a versatile oil, do you know it is the best oil for seasoning cast iron cookware as well? Flaxseed oil is mainly preferred for many reasons, including;

  • It has high amounts of Omega-3
  • It contains high amounts of unsaturated fats
  • It has a low smoking point

All the above qualities will help with the polymerization process of cast iron seasoning. Omega-3 produces the hardest of polymers which creates a very stable surface. So the oil will not flake off into the food you are cooking.

Moreover, as the oil is highly saturated, it will form a stronger seasoning. It takes less time and energy to season because of its low smoking point. All together, flaxseed oil is the best option to prevent uneven seasoning on a cast iron pan.

2. Preheat the Cast Iron Pan Before Seasoning

This is where most people make mistakes. They often forget to preheat the pan. It may not cause any severe issues, but it does affect the seasoning outcome. As you know, cast iron takes time to heat, and it distributes the heat unevenly.

So before you apply the oil, preheat the pan at first. This will help the oil to heat up uniformly. Thus, it will create an even seasoning.

3. Season While Keeping Your Cast Iron Cookware Upside Down

This is especially for seasoning on an oven. Many people do not turn their cast iron pans upside down while placing them in the oven. Possibly, this is not a usual process. So, what happens if you don’t keep it upside down?

The excess oil on the pan will accumulate unevenly on the pan. This will coat the pan unevenly and leads to the uneven seasoning on your cast iron pan. Thus, the food will stick to the uneven part of the surface.

Here you aim to create a nonstick finish. You will achieve it by placing the pan upside down in the oven. This will allow excess oil to drip off and leave an even coating throughout the pan.

4. Use a Thin Layer of Oil

Many people splash a lot of olive oil all over the pan to make sure every single point is lubricated. Well, it’s a bad practice. It even doesn’t work if you use tons of oil. In fact, doing this will cause uneven seasoning on cast iron cookware.

So what happens when you use too much oil?

It prevents the polymerization process from working correctly. Thus, you’ll end up with an uneven coating of seasoning on the cast iron cookware. So, make sure you are using a thin layer of flaxseed oil, olive oil, or vegetable oil. With a paper towel, spread it equally all over the surface of the pan.

5. Repeat the Seasoning Process Again and Again

If you think you’ll get a perfect result with just seasoning once, you are the wrong folk. Seasoning only once will not give you what you are expecting. However, some people prefer to season until they are satisfied.

Well, we prefer to season the cast iron cookware three times. It will help to add smooth layers of seasoning. Yes, season it again and again. Wipe oil with paper towels and bake the pan for one hour.

Repeat the process three times to spread the consistency of the seasoning. It may be a tedious thing to do. But, spending a few hours in a day will help you achieve long-lasting results. You can do it when you have free time.
