Dry cast iron in your oven: the key to rust-free, non-stick perfection

Cast iron cookware is a cherished kitchen staple, renowned for its exceptional heat retention and durability. However, after washing, it’s crucial to dry cast iron thoroughly to prevent rust and maintain its pristine condition. Enter oven drying, a foolproof method that effectively removes moisture and ensures your cast iron remains in top shape.

Materials You’ll Need:

• Cast iron pan or skillet
• Clean, dry towel
• Oven
• Oven mitts

Step-by-Step Guide: How to Dry Cast Iron in Oven

1. Wash and Rinse Thoroughly

Before placing your cast iron in the oven, wash it thoroughly with warm, soapy water. Use a soft sponge or brush to gently remove any food residue or grease. Rinse the pan thoroughly to remove any remaining soap.

2. Towel Dry

After washing, use a clean, dry towel to pat the cast iron dry. Remove as much moisture as possible, paying attention to crevices and corners where water tends to linger.

3. Preheat the Oven

Preheat your oven to 200°F (93°C). This low temperature will gently dry the cast iron without damaging its seasoning.

4. Place Cast Iron in Oven

Place the cast iron pan or skillet upside down on the middle rack of the preheated oven. This allows any remaining moisture to evaporate freely.

5. Dry for 30-45 Minutes

Leave the cast iron in the oven for 30-45 minutes, or until it is completely dry to the touch. The exact drying time may vary depending on the size and thickness of your cast iron.

6. Remove from Oven

Once the cast iron is dry, carefully remove it from the oven using oven mitts. Be cautious as the pan will be hot.

7. Cool and Store

Allow the cast iron to cool completely before storing it. To prevent rust, apply a thin layer of vegetable oil or seasoning wax to the surface and wipe off any excess. Store the cast iron in a dry place.

Seasoning Your Cast Iron

After drying your cast iron in the oven, it’s recommended to season it to enhance its non-stick properties and protect it from rust. Here’s how:

1. Preheat your oven to 350°F (177°C).
2. Apply a thin layer of vegetable oil or seasoning wax to the entire surface of the cast iron.
3. Place the cast iron upside down in the oven on the middle rack.
4. Bake for 1 hour.
5. Turn off the oven and let the cast iron cool inside.
