Equipment

  • 9x9-inch baking dish

Ingredients

French Toast Casserole

  • ½ loaf sourdough bread you can use any kind of loaf - artisan bread, brioche, french bread, white bread, challah bread...
  • 2 cups whole milk
  • 4 large eggs
  • ½ cup brown sugar
  • 1 teaspoon vanilla extract

Cream Cheese Icing

  • 4 oz cream cheese softened
  • 2 cups powdered sugar
  • ¼ cup heavy cream
  • ½ teaspoon vanilla extract

Instructions

Prepare the Casserole

  • Slice the sourdough bread (at least day-old bread works best) into 1-inch cubes. Set aside.
  • Add the milk, eggs, brown sugar, and vanilla extract to a small mixing bowl and whisk to combine.
  • Place half the sourdough bread cubes in a greased 9x9 casserole dish and pour half the egg and milk mixture over top. Then add the rest of the bread cubes and pour the rest of the egg and milk mixture over top.  
  • Cover with plastic wrap or a lid and place in the fridge for at least an hour before baking for best results.

Bake the Casserole and Prepare the Icing

  • Bake in a preheated oven at 375°F for 45 minutes, or until the top of the bread in the casserole is golden brown and the middle is no longer liquid.  
  • While the French toast casserole is baking, prepare the icing in a separate bowl.  Use a hand mixer or stand mixer to beat the softened cream cheese on medium-high for 2 minutes. Add the powdered sugar, vanilla extract, and heavy cream and beat on low for another 2 minutes until smooth.
  • Pour the icing over the casserole straight out of the oven and serve hot with fresh fruit and a drizzle of maple syrup.

Notes

  • Slightly stale sourdough works best.
  • Overnight soaking improves texture and flavor.
  • Add berries, pecans, or cream cheese cubes for variation.
