I can’t think of a better make-ahead brunch than this citrusy, just-sweet-enough baked French toast casserole. Studded with dates, pistachios, and an easy orange-scented custard (made right in the blender), it’s the best dish for pleasing a hungry crowd with minimal effort. If you’d like, you can prepare this baked French toast through step three the night before and store it tightly covered in the fridge overnight. Then carry on from step four and bake it in the morning while you enjoy your coffee.
