The Kentucky Derby Casserole is a beloved cornerstone of Southern brunch culture and race-day hospitality. Long before mint juleps and elaborate hats took center stage, Kentucky home cooks perfected hearty, make-ahead egg dishes that could feed a crowd while guests gathered for the main event. Essentially a savory strata or bread pudding, this recipe transforms humble day-old bread into a rich, custardy centerpiece layered with browned sausage, sharp cheddar, and classic aromatics. It’s a beautiful example of practical, crowd-pleasing comfort food—where simple ingredients are layered, soaked, and baked into something deeply satisfying and effortlessly elegant.
