Growing up, casseroles and large, make ahead dishes were big in my family. It took me a really long time to come around to loving leftovers; but now that I have a large hand in making sure meals are made and there is food to eat throughout the week, I’ve become more flexible. Mom’s comfort casserole was among the few things that I would happily eat over and over. Sadly, I did this with a lot of vigor, and usually ate the whole thing within the evening, if not over 2 days.
We’ve adapted her recipe to replace elbow macaroni with spiralized sweet potato, and excluded the cheese. If you have a high-quality hard cheese like cheddar, or even something like mozzarella, it would be amazing shredded on top (probably about 1/2 C would do). Dairy is an occasional splurge for us; but if you tolerate it well, sprinkle it on this amazing comfort casserole and go to town. I know we did.
