How to Season a Cast Iron Skillet – More Easy


A cast iron skillet is a versatile and durable kitchen tool that can last for generations if properly cared for. However, cast iron needs special care, including seasoning with oil or fat and baking at high temperatures to maintain its nonstick surface and prevent rust.

This creates a protective layer that prevents sticking and enhances food flavor, as the oil in the seasoning absorbs and imparts the aromas and tastes of cooked ingredients into subsequent meals.. By following these tips, you will be able to enjoy your cast iron skillet for many years to come.

Why Season a Cast Iron Skillet?

Cast iron is a type of iron alloy that contains carbon and other elements, such as silicon and manganese. Cast iron is strong and heat-resistant, but it is also porous and reactive, meaning that it can absorb moisture and react with acidic foods, such as tomatoes and vinegar. This can cause the cast iron to rust, corrode, and lose its nonstick properties.

Seasoning protects the cast iron from rust and corrosion by forming a barrier between the metal and external elements like air, water, and food. This process not only enhances the skillet’s cooking performance through even heat distribution and prolonged heat retention, enabling energy-efficient cooking at lower temperatures, but also enriches the flavor of your food. The oil used in seasoning absorbs the seasonings and spices, gradually infusing these flavors into your dishes.

How to Season a Cast Iron Skillet

Seasoning a cast iron skillet is not difficult, but it does require some time and patience. You will need the following items:

  • A cast iron skillet (new or old)
  • A mild dish soap
  • A stiff brush or sponge
  • A kitchen towel or paper towel
  • A neutral oil with a high smoke point, such as vegetable, canola, or grapeseed oil
  • An oven
  • A baking sheet or aluminum foil

Here are the steps to season a cast iron skillet:

  1. Preheat the oven to 200°C (400°F).
  2. Wash the skillet with warm water and a small amount of dish soap, using a stiff brush or sponge to remove any dirt, grease, or rust. Do not use steel wool or abrasive cleaners, as they can scratch the surface of the cast iron.
  3. Dry the skillet thoroughly with a kitchen towel or paper towel, or place it over low heat on the stove until all the moisture evaporates. Make sure the skillet is completely dry, as any water left on the surface can cause rusting.
  4. Apply a thin layer of oil to the entire skillet, inside and out, including the handle and the bottom. Use a kitchen towel or paper towel to spread the oil evenly, and wipe off any excess. You do not want the oil to pool or drip, as this can cause sticky spots or uneven seasoning.
  5. Place the skillet upside down on the oven’s middle rack, with a baking sheet or foil below to catch drips. Bake for an hour, then cool in the oven. The oil will polymerize, creating a durable, non-stick, rust-resistant coating.
  6. Repeat steps 4 and 5 at least two more times, or until the skillet has a smooth and black surface. The more you season the skillet, the better the nonstick and rust-proof properties will be. You can also season the skillet after each use, by applying a thin layer of oil and heating it on the stove until it smokes slightly, then wiping off the excess and letting it cool.

How Often to Season a Cast Iron Skillet

The frequency of seasoning a cast iron skillet depends on how often you use it, what you cook with it, and how you clean and store it. Generally, you should season your cast iron skillet whenever you notice any of the following signs:

  • The surface looks dull, gray, or patchy
  • The food sticks to the skillet or leaves residue
  • The skillet has rust spots or flakes
  • The skillet smells rancid or metallic

To prevent these problems, you should follow these tips:

  • Use your cast iron skillet regularly, as cooking with it helps to maintain and improve the seasoning. Avoid cooking acidic foods, such as tomatoes, citrus, or vinegar, as they can strip away the seasoning and damage the metal. If you do cook acidic foods, make sure to season the skillet afterwards.
  • Clean your cast iron skillet properly, by washing it with warm water and a stiff brush or sponge, without using soap or detergent. Soap can remove the oil and seasoning from the skillet, and detergent can leave a residue that can affect the taste of your food. If you have stuck-on food or burnt bits, you can use coarse salt or baking soda to scrub them off, or boil some water in the skillet to loosen them. Dry the skillet thoroughly after washing, and apply a thin layer of oil before storing.
  • Store your cast iron skillet in a dry and cool place, away from moisture and humidity. Do not stack other pans or utensils on top of the skillet, as they can scratch the surface and damage the seasoning. You can also place a paper towel or cloth inside the skillet to absorb any moisture and prevent rusting.
