  • Want something a little more than cinnamon? You can use any baking spice mix you like for this casserole! Whether that's pumpkin pie spice, apple pie spice, or even gingerbread spice.
Expert Tips:
  • Don’t skip toasting the bread! it really helps the bread absorb the custard.
  • When making the custard, make sure it is thoroughly mixed!
  • This casserole can be made same day or a day in advance.
  • If you choose to refrigerate overnight, remember to remove the casserole at least 30 minutes before baking.
  • Bake times may vary depending on the casserole you use, how your oven bakes, how thick or thin the bread slices are, etc.
