Recipe Notes

NOTE - This can be prepped and completely assembled the day before (this is what I do). Just cover with foil and keep in the fridge until day of and increase your bake time to about 30-35 minutes. Also, you can bake this at any temperature (if you have other things in the oven) just adjust accordingly (less time if higher temp, more time if lower temp).
