The name "macaroni pie" is confusing on multiple fronts. This recipe, from Nathalie Dupree and Cynthia Graubart's Mastering the Art of Southern Cooking is neither a pie nor made from macaroni. It also obscures the fact that the dish in question is actually just custard-style macaroni and cheese. But this old-school title is also a reminder of the history of the dish.

Squash casserole is an enduring favorite at Southern potlucks. I know that I ate plenty of the stuff growing up, but it was mostly because the flavor of the squash was covered up by ungodly amounts of cheese and butter. These days, I prefer actually tasting my vegetables. Luckily, Nathalie Dupree's version in Mastering the Art of Southern Cooking contains enough squash, onion, and peppers to taste more of summer produce than bulk cheese.
These biscuits are a cross between biscuits and cornbread, and it's a good combination.
