Does Cast Iron Work on Induction Cooktop

Ever since our ancestors explored creating fire, we are using it for cooking. But, technology has seen significant advancements that never failed to make our lives easy. This development can be seen in kitchen appliances, especially in the way of cooking. 

The thought of cooking without fire is not an alien subject to most of us now, because we have used an induction cooktop at some point in our lives. The mechanism of an induction cooker is very efficient as it cooks food using electromagnetism. That’s why it is the safest cooking option. The compact and portable design of premium induction cooktops allows us to take it wherever we go. They are much more energy-efficient than gas or electric cookers. 

But a major drawback of induction cooking is that it needs magnetic cookware to work, for example, a cast iron or a magnetic stainless-steel pan will work with an induction cooker. These are however passable options and are slowly becoming obsolete. Pans marketed as Non-stick induction ready cookware are the best to be used with induction cooktops. Also, you need to have electricity to prepare a meal using an induction cooker; it will not work during power cuts.

The Working of Induction Cooktop

Induction cookers use electromagnetism, a very power-saving and sophisticated way of cooking. When you plug in the induction cooktop, the heat passes through and creates an electromagnetic field which heats up the magnetic pot or pans on top of the cooktop. This is how an induction cooker works.

How does a Radiant Electric Cooker Works

There lies a great difference between the working process of radiant electric cooktops and induction cookers. Radiant cooktops get heated up, bypassing the electricity through the radiant coils. After the coils are hot, they transfer the radiant heat to the ceramic glass plate, and the heat goes into the cookware. The ceramic baseplate here is identical to that used in induction cooktops. Both are prone to scratches if inappropriate cookware is used to cook on them. This guides discusses the best type of cookware to be used on smooth glasstops.

Comparison between Radiant Electric Cooking and Induction Cooking

Electric Cooking vs Induction Cooking

Radiant electric cookers are cheaper than the induction ones. Radiant cookers are much similar to electric coil stoves; they are only a better version of stove cooking. That’s why radiant cookers do not need special cookware in order to work, unlike the case of an induction cooker, which demands magnetic cookware.

Radiant electric cookers are more energy-efficient than usual stove cooking; still, an induction cooker is the best energy-saving cooking option among these. Also, the brilliant technique of induction cookers is a planet-friendly way to cook. This electromagnetism enables induction cooktops to cook foods faster and evenly than radiant cookers, contributing to a more convenient lifestyle.

Can you use Cast Iron on an Induction Cooktop?

Cast Iron on an Induction Cooktop

Yes. You can use cast iron on top of your induction cooker.

An induction cooker only works with a certain type of cookware. As a rule of thumb, any cookware that sticks to a magnet will work with an induction cooktop. So, it works fine with cast iron and magnetic stainless steel cookware. This however does not mean that cast iron is the best type of cookware for an induction cooker. You have to ensure that the cookware has a flat and smooth surface in order to be compatible with an induction cooker. Same is the case with portable electric cooktops and smaller dual burner indcution cooktops.

Cast iron has a delicate alloy of iron and carbon, which makes it very fragile. And it contains a greater proportion of carbon, which is higher than steel.

How Cast Iron Affects on Induction Cooktop

How Cast Iron Affects on Induction Cooktop

Although you can use cast iron on top of the induction cooktop you have, it can lead to some unfavorable effects on your induction cooker. Because cast iron has a very grittier and rougher surface area, it leaves some prominent scratches on the induction cooktop, if used regularly. 

This further contributes to causing some damage to the induction cooker. You have to keep in mind that cast iron is a very slow heat conductor. This will increase the cooking time. The layer coating of cast iron can also end up chipping if the pan is made to face an overheating situation.

Tips to Use Cast Iron Skillets On Induction Cooktop

If you cannot find any other option than cast iron, you have to take some measures and follow a couple of tips in order to minimize the damage to your induction cooker. These are

1. Using Porcelain-Coated Cookware

The surface of cast iron is very rough. And because of that, cast iron leaves noticeable scratches on the induction cooker. This can easily be solved if you use a cast iron cookware with a porcelain coating. Porcelain coating enables the cookware to have a smooth surface without any grit. So, this will not cause damage to the induction cooktop.

2. Place a Parchment Paper on top of the Cooktop

To avoid any scratches, you can use a Parchment Paper on top of your induction cooker and place the cast iron cookware above it. This will ensure less friction. You can also use a baking mat to give nice protection to the cooktop’s glass. If you cannot find any of the two, go for a simple paper or tissue.

3. Use Enameled Cast Iron

An enameled cast iron has an enamel gaze, which is applied to the surface area of cast iron. This will ensure full protection against rust. So your cast iron would provide you a long-lasting performance as it has made rust-proof with the enamel gaze.

4. Season Cast Iron When Needed

Seasoning is a process in which vegetable fat or animal fat is used on the cookware’s surface. If your cast iron cookware is not an enameled one, you need to season it often to make it rust-resistant. Seasoning also decreases the friction between the Induction Cooktop and the cast iron. Also, it ensures your cookware has a non-stick surface for more convenient cooking.

Drawbacks of Using Cast Iron on Induction Cooktops

Drawbacks of Using Cast Iron on Induction Cooktops

Having all the measurements taken and the tips followed, you can still not be getting a good enough performance using a cast iron on the induction cooktop. This is because the way cast iron is created. The limitations of using Cast Iron on Induction Cooktops are –

1. Doesn’t Handle Sharp Temperature Changes Well 

Cast iron is very prone to thermal shock. This thermal shock happens when an object gets expanded quickly because of sudden temperature change, so your cast iron cookware develops cracks very often.

An Induction cooker heats up the pan very much faster than any gas cooker. So, if you use cast iron cookware on an induction cooker, the cooktop will transfer the heat quickly to the pan, which will give a thermal shock to the cast iron. Also, if you change the temperature settings and set your induction cooker on high and low in the middle of cooking, the cast iron will take longer to cook the food because it will take much time to adjust with the sudden heat change.

2. Uneven Cooking

One of the major aspects of induction cooktops is it provides even cooking in less time. But that function gets disrupted if you use cast iron on top of it.

Cast irons are a slow conductor of heat. It contributes to uneven cooking because the middle part of the cast iron heats up fast. The heat then gradually spreads to the sides of the pan. But the middle part contains maximum temperature. When you use it on an induction cooker, cast iron cannot get heated up quickly and provides slow and uneven cooking. 

That’s why you have to stir the ingredients much often to have an evenly cooked meal. Also, it takes a lot of time to cook.

So, if you are facing any of these problems, be assured that your induction cooktop works just fine, and you need to change the cookware.

Conclusion

This article provides you with a detailed analysis of various aspects around induction cooking and cast iron. You have known the answers if cast iron can be used with an induction cooker. It has also discovered what kind of measurements you have to take to ensure lesser damage to the induction cooker if you use cast iron. Still, cast iron has some limitations. 

This knowledge will help you to choose appliances and cookware best suited to your kitchen so that you can make the everyday boring cooking a convenient and satisfying one.
