This is a decadent, custardy breakfast casserole that combines the best of French toast and bread pudding. With juicy blueberries and creamy cheese, it's assembled the night before for a stress-free, crowd-pleasing brunch. It bakes up golden and fragrant, perfect for special mornings.
Use day-old or slightly stale bread for best texture. The overnight rest is crucial for full custard absorption. If the top browns too quickly, tent loosely with foil. Leftovers reheat well.
