What are the consequences of dishwashering a cast iron skillet?
A cast iron skillet which is regularly washed in the dishwasher will be progressively stripped down to bare metal, which will quickly and consistently rust. It will not be usable for cooking until you clean it of the rust and re-season it.
Incidentally, I think you might be confused by the term &quot;seasoning&quot;. Seasoning consists of polymerized oil, not &quot;bits of food&quot;, and its purpose is to protect the skillet and reduce sticking, not to produce better tasting food. If you don't want to use a seasoned pan, for whatever reason, you should not use cast iron.
