1. The cast iron pan has better sealing and heat preservation (for the cast iron pan with better workmanship). In fact, the sealing of the casserole is not bad, but it is a little worse than the cast iron pot. If you cook soup or stew, you really feel that the cast iron pot is better. You can try it yourself, ha, personal feeling ~

Cast iron pot is very convenient for pretreatment of ingredients. Mainly refers to the dishes that need to be fried first and then stewed, such as frying an onion first and then stewing a meat. Casserole doesn't mean that you can't do it at all, but it doesn't feel as good as cast iron pot.
