I didn't portion the same as the instructions so I ended up using more pasta sauce than necessary and it kinda overflowed my cast iron. All I would say is portion appropriately so as to keep it in the cast iron, otherwise I wouldn't have had to switch it to a baking dish. Turned out great still and everyone liked it. Fairly simple and took less time than it says. Next time I'll definitely use or make a better pasta sauce for added flavor.
