What You'll Learn
Boiling water in a cast iron pan can loosen stuck-on food
Boiling water in a cast iron pan is a great way to remove stuck-on food. This process is called deglazing. However, it is important to note that boiling water in a cast iron pan can also release the seasoning, leaving an uneven layer or patches. This can cause the pan to rust, as the seasoning protects the pan from rust and keeps it non-stick and easy to clean. Therefore, it is recommended to boil water in a cast iron pan for no longer than 10 to 15 minutes. If you have a newly seasoned pan, be extra cautious as the layer of seasoning won't be as tough as older pans.
To loosen stuck-on food, add room temperature or warm water to the pan before turning on the burner. Avoid adding cold water to a hot pan or hot water to a cold pan, as this can cause the pan to crack or warp. Bring the water to a gentle boil and let it simmer for a few minutes. You can then use a non-abrasive scrubber, held with tongs, to remove the loosened food. If there is stubborn residue remaining, boil some more water and dump it down the sink.
After removing the stuck-on food, dry the pan thoroughly. You can do this by heating it on the stove, ensuring that all the water has been wiped out first. You can then coat the interior with a light layer of oil. It is important to note that each time you cook with oil, you reinforce the layer of seasoning. If you do boil water in your cast iron pan and notice that the seasoning has been affected, you can always reseason the pan.

Boiling water for too long can wear down the seasoning
Boiling water in a cast-iron pan for too long can wear down the seasoning. The top layer of oil on the pan, or seasoning, is crucial for protecting the pan from rust and keeping it non-stick and easy to clean. This layer is built up over time through a process called polymerization, which occurs during repeated use of the pan.
When boiling water in a cast-iron pan, it is recommended to not boil the water for more than 10 to 15 minutes. Boiling water for a short amount of time, such as a few minutes, can be an effective way to remove stuck-on food from the pan. However, constantly boiling water or boiling water for too long can cause the seasoning to release, resulting in an uneven layer of seasoning or flaking. This can also lead to rust formation if the pan is not properly reseasoned.
The risk of damaging the seasoning by boiling water is higher in newly seasoned pans, as the layer of seasoning is not as tough compared to older pans. Additionally, acidic foods or sauces will break down the seasoning more quickly, so it is recommended to limit boiling these to no more than 10 to 15 minutes.
To prevent wearing down the seasoning, it is recommended to use a non-cast iron pot or pan for dishes that require a constant boil and a large amount of water, such as pasta, soups, and beans. For dishes that are simmered and contain less water, such as stews, chili, and cheese sauce, cast iron pans can be used for longer periods without damaging the seasoning.

Boiling water can cause rust to form
Boiling water in a cast iron pan can cause rust to form. This is because cast iron is prone to warping or cracking when exposed to extreme temperature changes. For example, adding cold water to a hot pan or hot water to a cold pan can cause it to crack or warp. Therefore, it is recommended to use room temperature or warm water when boiling water in a cast iron pan.
Additionally, cast iron pans that are not seasoned well or maintained properly can also be more susceptible to rust. Seasoning creates a protective layer on the pan that helps to prevent rust. However, boiling water for extended periods can wear down this seasoning, exposing the iron to moisture and oxygen, which can lead to rust formation. This is especially true for newer pans, as their seasoning is not as tough as that of older pans.
To prevent rust, it is important to dry the pan thoroughly after each use. Some people recommend drying the pan by heating it on the stove, as the pores in cast iron can hold onto water, creating an environment conducive to rust formation. Applying a light layer of oil after drying can also help protect the pan from rust.
It is worth noting that enameled cast iron is an exception. Enameled cast iron does not require seasoning and is less susceptible to rust due to its durable enamel coating. However, even with enameled cast iron, it is important to follow the manufacturer's instructions regarding temperature limits and care procedures.
In summary, boiling water in a cast iron pan can cause rust if the pan is not properly seasoned, maintained, and dried. Proper care and maintenance, including thorough drying and occasional re-seasoning, can help prevent rust formation.

Deglazing is a process that involves boiling water to clean cast iron skillets
Boiling water in a cast iron pan is generally safe, but there are a few things to keep in mind. Firstly, avoid adding cold water to a hot pan or hot water to a cold pan, as this can cause the pan to crack or warp. Instead, use room temperature or warm water and add it to the pan before turning on the heat. While boiling water for a short time is safe, constantly boiling water can cause the seasoning to release, leaving patchy or uneven layers. Therefore, it is recommended to limit boiling to 10-15 minutes to avoid damaging the seasoning. If you do notice the seasoning coming off, you can simply reseason your cast iron. Additionally, be cautious with acidic dishes as they can wear down the seasoning more quickly.
Deglazing is a process commonly used to clean cast iron skillets and add flavour to dishes. It involves adding liquid, such as water, chicken stock, wine, or vinegar, to a hot pan with stuck-on food. As the liquid heats up, it dissolves the browned bits of food, creating a flavourful sauce, soup, or gravy. While water can be used for deglazing, it is less preferred as it does not add flavour like other liquids. When deglazing with acidic liquids such as vinegar or wine, it is crucial to ensure that the pan is well-seasoned, as these liquids can eat away at the seasoning.
To deglaze a cast iron skillet, start by cooking your dish to the desired internal temperature. If making a thin sauce, you can pour out excess fat. Then, add your chosen liquid to the pan and heat it up, allowing it to dissolve the stuck-on food. For thicker gravies, you can add a thickening agent like flour and whisk the sauce. Deglazing is meant to enhance the flavour of your dish, so choose a liquid that complements your cuisine.
It is important to note that deglazing can affect the seasoning of your cast iron skillet, especially if it is not properly seasoned. If you are concerned about preserving the seasoning, it is recommended to use liquids with lower acidity, such as chicken or beef stock, or to ensure that your pan is well-seasoned before deglazing with acidic liquids. Additionally, regularly seasoning your cast iron skillet can help maintain its condition.
In summary, boiling water in a cast iron pan is generally safe for short periods, but constant boiling can affect the seasoning. Deglazing is a useful process for cleaning cast iron skillets and adding flavour to dishes by dissolving stuck-on food and creating sauces. It is important to use appropriate liquids, consider the acidity, and ensure proper seasoning to maintain the condition of your cast iron skillet.
