Can we talk about casseroles for a minute? Somehow they've gotten a bad reputation. Lots of people think of the casserole as old-fashioned, an unhealthy, inelegant symbol of 1950s cooking that doesn't really deserve much love or attention in our enlightened 21st century kitchens. Sure, there are versions that were popular when I was a kid that I'd be horrified to ever see again (canned salmon and tomato soup is not a combination I particularly pine for), but those are the ones that mostly give casseroles a bad name.
