French Toast Casserole

You will not believe how delicious and easy it is to turn French toast, a classic breakfast recipe, into a casserole! All you need are a few simple ingredients, and then it’s hands-off cooking in the oven.

  • 13x9 inch baking pan


For the Filling:

  • 6 large eggs
  • cups whole milk (370mL)
  • ¼ cup packed brown sugar (55g)
  • teaspoon vanilla extract
  • ¾ teaspoon ground cinnamon
  • ¼ teaspoon salt
  • 1 large loaf French bread cut into 1-inch cubes (about 14 to 16-oz.)

For the Topping:

  • ¼ cup packed brown sugar (55g)
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon salt
  • ¼ cup cold butter diced (57g)

To Serve

  • maple syrup
  • powdered sugar


  • Preheat the oven to 375F. Lightly grease a 13x9-inch baking dish with butter.

For the Filling:

  • In a large bowl, whisk together the eggs, milk, brown sugar, vanilla, cinnamon, and salt. Stir in the bread until fully coated. Spoon into the prepared baking dish.

For the Topping:

  • In a small bowl, whisk together the brown sugar, cinnamon, and salt. Sprinkle evenly over the bread mixture. Dot the top with butter.
  • Bake for about 30 minutes or until the filling is set and the top is golden brown. Cool for a few minutes before serving. Serve with powdered sugar and maple syrup, if desired.



  • For a more seasonal touch, you can add in different spices instead of cinnamon, such as pumpkin spice or apple pie spice.
  • Instead of dusting with powdered sugar after the casserole comes out of the oven, try coating them in cinnamon sugar to change things up. You have to do this while the bread is still warm so the sugar mixture will stick.
  • Fresh bread is not ideal for this recipe as it soaks up too much egg mixture, making the casserole soggy on the inside.
  • If you only have fresh bread, you can toast the cubes for a couple of minutes to dry them out before soaking them in the egg mixture.
  • Make sure your brown sugar is soft and moist. If your brown sugar has hardened, don’t worry, it’s an easy fix! I wrote a detailed post on how to soften brown sugar.
