Ingredients

  • 16 oz bread (french bread, challah, brioche, etc)
  • 6 eggs
  • 1 cups milk (anything but skim milk)
  • 1 cup half and half (or heavy cream)
  • 1/2 cup brown sugar
  • 1/4 tsp salt
  • 1 tsp cinnamon
  • 1 tsp vanilla extract

For the Crumble Topping:

  • 1/2 cup all purpose flour
  • 1/2 cup brown sugar (packed)
  • 1 tsp cinnamon
  • 1/8 tsp salt
  • 1/2 cup butter (cold)

Instructions

  • Grease a 9x13 pan.

  • Add your eggs, milk, half and half, brown sugar, salt, cinnamon, and vanilla extract to a large bowl. Whisk it all together.
  • Pour the egg custard mixture over the top of the bread evenly. Flip some of the bread pieces over if they don't get any custard on them while pouring.
  • Cover the pan and place it in the fridge to chill until needed, at least 2 hours, preferably overnight (10 hours).

For the Crumble Topping:

  • (You can make this the night before, or the morning of) In a medium bowl, whisk together the flour, brown sugar, cinnamon, and salt.
  • Use a pastry blender or 2 forks to cut the butter into the mixture evenly, until you have small pea sized clumps. Cover in an airtight container, or ziptock bag, and place in the fridge until you're ready to bake, unless using immediately.

For Baking:

  • When you're ready to bake it, remove the pan from the refrigerator and let it come to room temperature while you preheat the oven to 350 degrees
  • Break the crumble into small pieces if you made it ahead of time.
  • Sprinkle the crumble over the top of the french toast casserole evenly.
  • Bake for 35 to 55 minutes, until the casserole is cooked through and no longer soggy.
  • Let cool for a few minutes, then slice up and serve.
  • Top individual portions with powdered sugar, butter, and syrup as desired.
