This easy Christmas morning breakfast bake is the dish you make when you want to feel present, not stressed. It comes together in about ten minutes of active work, then the oven does the rest.
Use day-old bread for best texture. Don’t skip the resting time—it allows the bread to absorb the custard. Season generously with salt. Let the casserole rest before serving to ensure clean slices. For make-ahead, assemble the night before and refrigerate. For freezing, assemble unbaked, wrap tightly, and freeze for up to 3 months; thaw overnight in fridge before baking.
