Notes

Total prep time does not include refrigerating the French Toast overnight.
*I cut my bread into cubes when I first buy it, then let the bread dry out on my counter that day then make my French Toast Casserole the following night. If you don't have time for day old bread, you can buy fresh bread, cube it, spread it out on a baking sheet and bake at 350 degrees F for about 20 minutes.
**The Brown Sugar Pecan Crumble can be made the same time as the French Toast then refrigerated or prepared the morning of baking the casserole.
***If you don’t have a food processor, add ingredients to a mixing bowl and cut butter into brown sugar with pastry cutter, 2 forks, etc.
