Ingredients

  • 16 ounce challah bread loaf
  • 6 eggs large
  • 2 cups whole milk
  • 3/4 cup heavy cream
  • 1/4 cup sugar
  • 1/2 cup brown sugar
  • 1/2 teaspoon kosher salt
  • 1 tablespoon vanilla
  • 1/2 teaspoon nutmeg
  • 2 teaspoons cinnamon

CRUNCH TOPPING

  • 1/2 cup flour
  • 1/2 Cup Cold butter
  • 1/2 cup brown sugar packed
  • 2 tsp cinnamon
  • 1/2 teaspoon salt
  • syrup for drizzling

Instructions

  • Start by cutting or tearing your bread into bite sized pieces and laying them out on a baking pan.  Toast your bread for 10 - 15 minutes at 225 degrees until your bread is crusty. 
  • Remove bread and move to a 9 x 13 baking pan sprayed with non-stick spray. In a large mixing bowl, whisk together eggs, milk, heavy cream, sugar, brown sugar, vanilla, nutmeg, salt and cinnamon and then pour evenly over your Overnight Challah French Toast Casserole bread. Lightly push bread down to make sure all the pieces have been covered with the egg mixture. Cover pan with foil and move the refrigerator for at least 2 hours or overnight. 
  • When ready, mix together flour, cinnamon, brown sugar, salt and cold butter in a mixing bowl. Remove Overnight Challah French Toast Casserole from the refrigerator and sprinkle flour mixture evenly over the top. Return the foil to the top of the casserole and bake in the oven for 25 minutes at 350 degree. 
  • After 25 minutes, remove the foil and continue to bake for another 20 - 25 minutes. When done, remove from oven, drizzle with syrup and serve immediately.
