Notes

To prepare this casserole ahead of time:

After the egg custard is poured over the bread and blueberries, cover tightly with Saran Wrap, and store in the refrigerator overnight, or for just a couple of hours.
The following day (or when ready to eat), prepare the topping and sprinkle over top the casserole, and bake.
Likewise, you could prepare the topping ahead of time, and store in the refrigerator as well.

Store leftover casserole in an airtight container in the fridge for 2-3 days. Heat leftovers in microwave.
