This casserole is a wonderful addition to a holiday lunch, a special brunch, or a weeknight dinner for those who crave comfort food. With very little preparation and the convenience of frozen hashbrowns, our recipe is a great base for more elaborate dishes that you might want to concoct. Think of bacon bits, cubed ham, ground beef, chopped leftover turkey, or sunny side eggs on top. Use fresh or frozen vegetables to make a heartier casserole or leave as is for a simple but flavorful side dish. Add a buttered bread crumb topping for some extra texture and crunch, or grate some parmesan or pecorino for an extra layer of salty tang. As you're using the oven, try to make a whole dinner without turning your stove on by serving our casserole with roasted chicken thighs, and some roasted cauliflower.
