Notes

  • Make sure the bread you use when making this casserole is at least one day old. This is important because you want the bread to be very dry. Dryer bread will soak up the custard better and won't fall apart in the soaking and cooking process.
  • In this recipe I use brioche bread, but you can certainly use  Challah or a French Baguette.
  • If you want to make this casserole the day of and you don't have enough time to soak the bread overnight you can toast the chunks of bread in the oven just until they are slightly toasty.
