Imagine the best French toast you have ever had, transformed into a baked casserole that feeds a crowd and requires zero morning effort. That is exactly what this recipe delivers.
You tear thick bread into cubes, soak them in a rich vanilla-cinnamon custard overnight, then top with a crunchy brown sugar streusel and bake until golden and puffy. The result is a cross between bread pudding and French toast — crispy and caramelized on top, soft and custardy within.
