Can You Cook Tomato Sauce on a Cast Iron? (What Happens and Ways to Do It Right!)

If you’re the type of person who loves to cook, then you probably enjoy using cast iron. It’s durable, versatile, and can withstand high heat—which is ideal for cooking tomato sauce, right?

Not so fast. It might not be a good idea to cook tomato sauce on a cast iron skillet.

But hey, we’ve got you covered on exactly what to do if you want to do it anyway.

Can you cook tomato sauce in a cast-iron skillet?

You can technically cook anything in a cast iron pan. The real question is: Should you cook a tomato sauce in a cast-iron pan? For that, the answer is not really. A well-seasoned and sealed pan will not be damaged by cooking something acidic in it once; however, cooking acidic things in it repeatedly can damage the seasoning as well as the pan itself.

What does tomato sauce actually do to cast iron?

When tomato sauce makes contact with the surface of cast iron materials, the metal begins to react with the acid to form a metallic salt.

In chemistry, this process occurs by dissociation, where the acid dissolves and oxidizes the metal. Exposing the metal to oxygen and water makes things worse.

In turn, this produces rust.

The fact of the matter is, even introducing water to cast iron starts the process of rusting.

However, when you’re introducing acid to the mix, it speeds up the process even further.

Does the tomato acidity damage the cast iron?

The acidity in tomatoes can damage cast iron, as the molecules released from the metal can corrode it over time.

When cooking acidic foods in a cast-iron skillet, you should be careful and do things like a boil, steam, or roast them to make them less acidic.

Even though you can still cook acidic foods in a cast-iron skillet safely and get the flavor and texture you want, too much simmering could cause the surface to rust, which would mean you’d have to reseason the skillet afterward.

What can you do if your cast-iron skillet is easy to clean and take care of? 

All you need is soap and water. A cast iron skillet is easy to clean and take care of. All you need is soap and water.

When it comes to reseasoning, simply clean off any rust or seasoning damage and start fresh. Also, you shouldn’t leave the skillet on the stove or in the oven for a long time without watching it.

You can use a combination of white vinegar and water and submerge the rusted area of your cast iron in it.

Keep it soaked in the mixture for 30 minutes to a few hours, and then take it out and scrub it to easily get rid of the rust buildup.

Cast-iron skillets are highly durable and can be found at many thrift stores, antique shops, and flea markets.

But leaving something like tomato sauce in it for an extended period of time can practically eat away at its surface.

With proper care, cast iron skillets can last for years without becoming ruined.

Can seasoning your cast iron prevent tomato damage?

The point of seasoning cast iron is to create a barrier that keeps the acidic tomatoes from making the metal react.

This layer of protection keeps the acidity of the tomatoes from touching the surface of the cast iron.

That means no reaction and no leaching.

This will help preserve the flavor of the dish and prevent any metallic tastes.

Also, seasoning cast iron stops tomatoes from sticking and burning, which can ruin the flavor and quality of your sauce.

Things you should do with your cast iron before cooking with tomato sauce

The main issue with cooking tomato sauce in a cast iron skillet is that the acids in the food can break down the seasoning on the pan as well as break down and damage the pan itself.

The most important thing you need to do when cooking any sort of acidic sauce in a cast iron skillet, like tomato sauce, is to ensure that you have a good seasoning on the pan prior to cooking.

This is going to protect the pan from the acid in the food and also prevent the food from turning bitter and becoming inedible.

Your seasoning should be intact and ready to use before you put any tomato sauce or tomatoes in your cast iron.

You also want to ensure that you are not cooking it for a super long time and that you clean your pan immediately after you are done cooking your tomato sauce.

Things you should consider while cooking tomato sauce in your cast iron

While cooking your sauce, there are some things you can do to prevent damage as well.

First, make sure you are not using a utensil to stir which is going to damage the bottom of the pan. You want to use a rubber or wooden spoon to stir. Second, make sure you are not using heat that is too high.

The higher the heat, the more likely it is that your sauce is going to remove the seasoning and potentially damage your pan.

You also want to make sure you are only minimally moving your sauce. Constant stirring is going to damage the coating on your pan and is also going to potentially change the flavor of your sauce overall.

Lastly, you want to make sure you are paying close attention to your sauce and are not letting it burn. If it burns to the pan, you are going to have far more damage to deal with than you would if you made sure the pan did not get damaged.

Things you should do with your cast iron after cooking with tomato sauce

If you have cooked tomato sauce in your cast-iron skillet, the end is not near.

There are a few things you can do to minimize damage and ensure your pan is going to be fine. You first want to make sure you wash your skillet well after cooking.

You want to remove the acidic tomato as quickly as possible so that you can start the repair process.

You want to wash the pan in warm, soapy water as quickly as you can, and make sure you scrub the pan to remove any remnants of the tomato sauce from the pan.

You then want to allow the pan to dry fully. You can then inspect the seasoning to see if you need to re-season the pan or if you can just put it away for another day of use.

How to repair and clean your cast iron from tomato sauce damage

If you find that the seasoning of the pan is damaged, you do need to go ahead and re-season the pan.

If you do need to re-season, your first step is going to be to heat up the pan so that the old seasoning can be removed.

After you have removed the old seasoning, spread a very thin layer of oil all over the pan,  and then place it in the oven at about 400 degrees Fahrenheit.

Allow the pan to stay in the oven for about 20 minutes, then allow it to cool fully in there.

This is going to allow the pores of the metal to open up so that the seasoning can go into the pan.

How many layers of seasoning does it take to protect your cast iron from tomato sauce?

Cooking with a cast iron skillet can affect the taste of tomato sauce.

Because tomato sauce is acidic, it may break down the seasoning on the pan, giving the sauce a metallic taste.

To avoid this, it is important to season or enamel your cast-iron skillet before use and remove acidic foods from it after cooking. Re-seasoning is also an option if needed.

But the real question is, how many layers does it take to fully protect your cast iron from the treacherous properties of tomatoes?

To avoid the harsh effects of tomato sauce, I recommend layering at least three layers of oil seasoning on your cast iron.

In fact, three layers are the standard in most cases. Also, make sure you reseason your cast iron at least 2 to 3 times a year.

The more you cook with your cast iron, the more the heat and food eat away at the surface layers, and over time, if you don’t reseason regularly, you’ll lose that non-stick protective property.

How long can I cook tomato sauce in cast iron?

You can cook your tomato sauce in your cast iron for up to an hour before it really causes damage.

The general rule of thumb with a cast iron pan and with something acidic like tomato sauce is that you want to cook it for as little time as possible.

The less time that you are cooking your tomato sauce, the better, and the less time that it has to cause any damage to the pan.

It’s not only tomato sauce that can damage your cast iron

Vinegar

Vinegar is included as one of the things that can damage cast iron because it is an acidic substance.

When used to clean a skillet, vinegar can eat away at the cast iron from the inside out, making it more likely to break when heated and possibly leaking metal into the food, which can make it taste bad and could be bad for your health.

Lime juice

The addition of lime juice is important when cooking acidic ingredients in cast iron cookware, as acidic ingredients can erode the seasoning on the pan and make food taste metallic (just as vinegar will).

By making the dish less acidic, lime juice helps to counteract this effect. But it’s not always great for pans made of cast iron.

Additionally, it is important to avoid long-simmering with heavy lime juices in cast iron pans because the longer and hotter the exposure, the more likely it is to damage your seasoning and pan.

Soda

Surprisingly, some people do cook with soda as an ingredient.

Soda has been found to be a common ingredient in cast iron cookware, and it can have damaging effects on the metal.

Studies have shown that soda can cause rust and corrosion, leading to damage to cast iron cookware.

If you run an experiment and pour a can of Coke into a cast-iron skillet and leave it there for a few hours, you’ll see corrosion occur.

Wine

Research has shown that wine can offer health benefits, making it a wellness drink.

So, when cooking with a cast iron skillet, adding a splash or even a lot of wine can help make the food taste better and may also be good for your health.

However, wine is acidic, and like all the other acidic ingredients mentioned before, it can damage your cast iron if left simmering in the heat or resting in the pan for too long.

What type of cookware is best for tomato sauce?

The types of metal cookware that don’t react with acids are usually copper, ceramic, and stainless steel.

Ceramic pots and Dutch ovens are incredibly durable when it comes to cooking with acidic foods like tomato sauce.

The type of materials that usually work well with foods and ingredients that include tomato sauce are those that have natural non-stick properties.

The next time you’re wondering if you can cook tomato sauce in a particular pan, just ask yourself, is it non-stick?

If it’s stainless steel or made with some enamel layer coated all around it, then there’s a good chance you’ll be ok.

Do they have saucepans made of cast iron?

There are smaller skillets that are made of cast iron, but a saucepan in the traditional sense is not something that you are likely to find made of cast iron.

You can find coated or enameled cast iron that has the same heating properties as cast iron but is easier to use and has less potential for damage from things like tomato sauce.

Is it a good idea to get your iron from rusty cast iron?

There’s no guarantee that a person can get iron from a rusty cast iron skillet.

However, it’s generally believed that a person who is eating food made on a cast-iron pan will absorb some amount of iron residue from the pan itself.

In fact, there have been a few studies involving scientists cooking tomato sauce in a cast iron pan. Before cooking, they determine the iron content in the tomato sauce, which is about 2 mg. After cooking, the concentration of iron climbed to 5 mg.

The dishwasher can strip away the protective seasoning from cast iron, which can lead to rusting. It is not clear if the rust, if it is there, has enough iron in it to be used for food or other things.
