15 Comforting Fall Casseroles You Can Make Ahead

Cozy and comforting, casseroles are essential fall dishes for weeknights and holidays alike. When the days are chilly, we love turning on the oven, popping in a saucy, often cheesy dish of various colors, textures, and flavors, and watching it emerge in golden perfection. Better yet, lots of casseroles can be prepared ahead, at our leisure, and simply baked or reheated when it's time to eat. We've rounded up our favorite casseroles with autumnal ingredients, from creamy gratins to baked pasta dishes, that can be made at least partially in advance to keep mealtime easy and delicious.
