A deep fryer offers crispy results for fried chicken, but a cast-iron skillet provides better control over oil temperature and cooking consistency. Unlike a fryer, which can use excessive oil, a skillet allows for smaller batches and easier cleanup. Chefs often prefer skillets for their ability to render fat evenly and create a golden-brown crust. The method also reduces the risk of splattering and makes it easier to flip food for even cooking.
A deep fryer may seem ideal for cooking homemade fried chicken, but you should really consider this type of pan instead.
