French Toast Casserole

French Toast Casserole with cinnamon sugar topping is soft and fluffy on the inside, and golden brown on top. Make it overnight and bake in the morning, or you can prepare it in the morning and bake it immediately. Either way - it's the perfect breakfast for a crowd.

French Toast Casserole

  • 1 large loaf of bread , 16-18 oz
  • 1 3/4 cups milk
  • 6 large eggs
  • 1/4 cup sugar
  • 2 tablespoons butter , melted
  • 2 teaspoons vanilla extract
  • 1/2 teaspoon cinnamon

Cinnamon Sugar Drizzle

  • 1/4 cup unsalted butter , melted
  • 3 tablespoons brown sugar
  • 1 teaspoon cinnamon


  • Preheat the oven to 350F degrees and lightly grease a 3-quart (or 9x13 inch) casserole pan.
  • Chop the bread into squares and place in the casserole dish.
  • In a large bowl whisk together the milk, eggs, sugar, 2 tablespoons butter, and cinnamon.
  • Pour the mixture over the bread being sure to cover evenly. Give the mixture a stir using a rubber spatula to coat if necessary.
  • In a small bowl whisk together the ingredients for the cinnamon sugar drizzle. 
  • Drizzle it overtop of the French toast casserole.
  • Cover the pan with aluminum foil and bake for 30 minutes covered. Remove the foil and continue baking for 15 minutes, or until the top looks golden. *
  • Let cool for 5 minutes before cutting into slices and serving. Careful - the pan is HOT. 
  • Serve with a sprinkle of powdered sugar or cinnamon, maple syrup and/or whipped cream. 


*I recommend baking this covered with aluminum foil for the first 30 minutes because otherwise the top can burn but the inside won't be cooked yet. 
**Store leftovers in an airtight container in the fridge. Warm in the microwave before enjoying.
