A cast-iron skillet can last for decades if it’s treated well. Many people still cook with pans that have been passed down through the family, and once a skillet is properly seasoned, it only gets better with regular use. It handles high heat well, works for everything from cornbread to steaks, and can become one of the hardest-working pans in the kitchen.

Still, cast iron is easy to damage if you don’t know the basics. A few common habits can leave your skillet rusty, sticky, dull, or harder to cook with over time. The good news is that most of these mistakes are simple to avoid once you know what to watch for. Here are some of the most common cast-iron skillet mistakes people make and how to keep your pan in great shape for years to come.

1. Overheating the Skillet

Allowing your cast-iron skillet enough time to preheat is crucial before you begin cooking. Like with any cookware, proper preparation makes all the difference. If you let it get too hot, you risk food sticking, burning, and uneven cooking, which can ruin your meal.

2. Lack of Seasoning

Proper seasoning of your cast-iron pan can greatly extend its lifespan and protect it. To keep it in top shape, be sure to season it with cooking oil. Here’s a step-by-step guide on how to season your cast-iron pan using olive oil.

3. Improper Cleaning

To maintain your favorite skillet in excellent condition, regular cleaning is essential! However, your cast iron doesn’t require a thorough scrubbing after every use. Over-cleaning and using too much detergent can strip away the seasoning that makes it so valuable.

4. Storing a Wet Skillet

Storing a wet cast-iron skillet is a sure way to invite rust and mold. To prevent this, ensure it’s thoroughly dried before storing, and avoid letting it air-dry.

5. Storing in a Cramped and Humid Environment

Stacking your skillets in cramped spaces or in humid environments can cause damage, reducing their performance.

6. Using the Wrong Utensils

Using inappropriate utensils, like metal spoons and forks, can scratch and damage the surface of your skillet. To protect its finish, opt for wooden or silicone utensils. Investing in quality utensils is worthwhile, as they are durable and easy to maintain.

7. Overcrowding the Skillet

Overcrowding the skillet can prevent food from properly cooking evenly, resulting in soggy, less flavorful dishes. Give your ingredients sufficient space to achieve the best results.

8. Cooking Delicate Foods

While cast iron is excellent for high-heat cooking and browning meats, it’s not ideal for delicate foods like seafood or eggs. The intense heat can make it difficult to handle flaky fish or soft eggs without breaking them. Consider using stainless steel pans for these types of dishes.

9. Cooking Acidic Foods

Acidic foods, such as tomato sauce or lemon juice, can develop a metallic taste when cooked in a cast-iron skillet. While safe to eat, it’s not the most pleasant flavor. If you choose to cook acidic foods in your skillet, limit the cooking time to under 15 minutes to minimize the off-flavors.

10. Storing Food in the Skillet

It might be tempting to leave your meal in the skillet after cooking, but this can promote bacterial growth and compromise the seasoning. To keep leftovers safe, it is better to transfer them to proper storage containers.

11. Soaking in Water

Soaking your cast-iron skillet in water can cause the seasoning to absorb moisture, making it more susceptible to rust. Instead, rinse the skillet with warm water to loosen stuck-on food, and use a sponge or washcloth to clean it. Avoid steel wool, but baking soda and salt can be used as gentle abrasives.

12. Not Enough Time To Cool

Avoid shocking your skillet with cold water. An unexpected temperature change can ruin the surface. Instead, allow it to cool down before washing, keeping its natural coating in optimal condition.
