How to Season Cast Iron Cookware for Long-Lasting Performance

Cast iron cookware has long been a favourite in both home and commercial kitchens worldwide for its durability, even heat distribution, and ability to improve with age. However, to get the most out of your cast iron pans, skillets, and grills, seasoning is a must. In this guide, we will explain what seasoning is, why it’s important, and how to do it correctly, ensuring your cast iron cookware delivers perfectly cooked dishes every time.

What Makes Cast Iron Cookware Stand Out?

Cast iron cookware is renowned for its ability to retain and distribute heat evenly, making it ideal for a variety of cooking methods. From frying and baking to searing and grilling, cast iron provides unmatched versatility. The material’s durability means that, with proper care, cast iron cookware can last for generations, often improving its performance over time.

However, its porous surface can easily absorb food particles and moisture, which may lead to rusting and sticking. This is where seasoning comes in.

Why Do We Need to Season Cast Iron Cookware?

The term ‘seasoning’ has nothing to do with adding salt or pepper. Seasoning cast iron cookware is a process of applying a thin layer of oil to the surface of the pan and then heating it. When heated to high temperatures, a chemical reaction called polymerisation takes place. This process bonds the oil to the cast iron, creating a smooth, durable surface that is resistant to rust and prevents food from sticking. Without seasoning, cast iron is prone to damage from moisture, food acids, and even oxidation.

Seasoning also enhances the cooking experience by improving the cookware’s non-stick qualities, helping to develop rich flavours over time. As you continue to season your cookware, the surface becomes more refined, offering an even better cooking experience with each use.

How to Season Cast Iron Cookware

Seasoning your cast iron cookware is straightforward, but it’s important to follow these steps carefully for the best results:

1. Clean the Cookware: Before you start seasoning, thoroughly clean your cast iron cookware with warm water and a brush to remove any factory residue or rust. Avoid using soap, as it can strip away any existing seasoning.
2. Dry Completely: Once clean, dry your cast iron thoroughly with a towel or heat it on the stove to remove any excess moisture. Any water left on the surface can interfere with the seasoning process.
3. Apply Oil: Choose a high-smoke point oil such as vegetable oil, flaxseed oil, or grapeseed oil. Using a paper towel, apply a thin, even layer of oil to the entire surface of the cookware, including the exterior and handle.
4. Bake the Pan: Place the pan upside down in a preheated oven at around 200°C (400°F). You can place a sheet of aluminium foil or a baking tray on the lower rack to catch any drips. Bake for one hour, then turn off the oven and let the cookware cool inside.
5. Repeat if Necessary: For the best non-stick results, it’s recommended to repeat this process 2-3 times, applying a fresh layer of oil each time.

How Often Should You Season Cast Iron Cookware?

The frequency of seasoning depends on how often you use your cookware. Generally, it’s a good idea to season your cast iron every few months if you use it regularly. If the surface starts to lose its non-stick qualities or you notice rust, it’s time to re-season.

The Benefits of Seasoning Cast Iron Cookware

Properly seasoned cast iron cookware offers several key benefits:

• Non-stick Surface: A well-seasoned cast iron pan provides a naturally non-stick surface, making cooking and cleaning much easier.
  
• Prevents Rusting: Seasoning creates a protective layer that prevents moisture from coming into contact with the iron, which helps to stop rust from forming.
  
• Improved Flavour: Over time, the seasoning builds up and enhances the flavours of the food cooked in the pan. It adds a subtle, rich flavour to every dish, making it a favourite for searing meats and baking.

• Highly versatile: Can be used to cook almost anything and suitable for use on most cooking sources including open flames.
  
• Durable: With proper care, seasoned cast iron cookware can last a lifetime. With regular seasoning it can improve in quality, the longer it’s used.

How to Clean Cast Iron Cookware

Cleaning cast iron requires a slightly different approach than other types of cookware. Here’s how to maintain your seasoned cast iron:

1. Avoid Soap: As mentioned earlier, soap can strip away the seasoning. Instead, use hot water and a stiff brush or non-abrasive sponge to clean your pan. For stuck-on food, a paste of coarse salt and water can be used to scrub the surface.
   
2. Dry Immediately: After cleaning, dry your cast iron pan immediately with a towel to prevent rust. You can also place it on the stove for a minute to ensure it’s completely dry.
   
3. Reapply Oil: Once dry, apply a thin layer of oil to the surface while the pan is still warm. This helps maintain the seasoning and prevent rusting.
   
4. Do Not Soak: Avoid submerging and soaking the cast iron pans in water and do not use a dishwasher.

How to Clarify Your Cast Iron Cookware

With regular use, you may notice a greasy build-up on the surface of your cast iron cookware, which can affect your cooking results and the overall finish of your pan. This is completely normal, but it’s important to address it by clarifying your pan to maintain that perfect, non-stick surface.

To clarify your cookware, begin by heating your pan on the hob. Once it's hot, add a generous amount of large chunks of salt (avoid using table salt as it’s too fine). Swirl the salt around to cover the entire surface. The salt will absorb any excess moisture and grease, gently scrubbing the surface and returning it to its seasoned state.

This simple process helps to remove unwanted residue and refresh your pan, ensuring it’s ready for your next cooking session. Regular clarifying will help maintain the integrity of the seasoning, keeping your cast iron cookware in top condition for years to come.

How to Cook with Cast Iron Cookware

Cooking with cast iron is simple, but there are a few tips to get the most out of your pans:

• Preheat Your Pan: Cast iron takes longer to heat up, but once it’s hot, it retains heat exceptionally well. Always preheat your pan before adding food to ensure even cooking.
  
• Use the Right Tools: Avoid using metal utensils, as they can damage the seasoning. Opt for wooden or silicone utensils instead.
  
• Avoid Cooking Acidic Foods: While your cast iron pan improves with use, cooking acidic foods like tomatoes or citrus too often can break down the seasoning. Use them sparingly.
