No, you do not need to wash a cast iron skillet after every use. In fact, washing a cast iron skillet with soap and water after each use is generally discouraged as it can remove the skillet's seasoning, which is a protective layer of polymerized oil that develops over time, giving the pan its non-stick properties and preventing rust.
Instead, the typical care for a cast iron skillet after each use involves a process called "deglazing" or "debriefing." Here's how you can do it:
- Allow the skillet to cool slightly after cooking.
- Pour a small amount of water into the warm skillet (about 1/4 to 1/2 inch) while it's still on the stove.
- Use a wooden spoon or spatula to gently scrape off any food particles or residues stuck to the surface while the water is simmering. This process helps to loosen and lift off any food remnants.
- Pour out the water and food debris and wipe the skillet with a paper towel or a soft cloth until it's clean.
- Place the skillet back on the stove and apply a thin layer of cooking oil or a solid fat like lard or bacon grease all over the cooking surface, including the handle.
- Turn off the heat and let the skillet cool completely. The residual heat will help the oil to bond with the surface, replenishing the skillet's seasoning.
It's important to note that if your cast iron skillet is heavily soiled or has stubborn residues, it's acceptable to use a small amount of mild soap and water occasionally to clean it thoroughly. However, after doing so, make sure to dry it immediately and apply a thin layer of oil to prevent rust.
Regular maintenance and proper seasoning will keep your cast iron skillet in excellent condition, ensuring its longevity and non-stick properties. Remember that a well-seasoned cast iron skillet becomes more non-stick and improves with time and proper care.
