A simple and delicious overnight French toast casserole soaked in custard and topped with rich, buttery caramelized bananas. Perfect for a fuss-free, comforting breakfast or brunch.
Use day-old bread for best texture; fresh bread should be lightly toasted before cubing. Caramelize bananas fresh before serving to maintain texture and gloss. Tent casserole with foil if browning too fast. Adjust custard thickness by adding milk or eggs as needed. Can freeze baked casserole up to 1 month.
