Additionally, adding cast iron skillets to your cast iron cookware collection can complement other cast iron pieces, such as square cast iron frying pan, oval cast iron skillets, and cast iron round skillet. Frying pans can be combined with these other pieces to expand your cooking capabilities. For example, you can use a frying pan to cook bacon and eggs, while using a cast iron round skillet to make a savory sauce or a square skillet to sear a steak.
