A cozy and indulgent French toast casserole soaked overnight in a vanilla-cinnamon custard and topped with a crispy maple brown sugar streusel. Perfect for hassle-free mornings and crowd-pleasing brunches.
Use day-old or lightly toasted bread to prevent sogginess. Let eggs and milk come to room temperature before mixing for best custard texture. Keep butter cold when making streusel for crumbly topping. Tent with foil if streusel browns too fast. Soak bread overnight for best results; minimum 4 hours if short on time.
