  • 9x13 casserole pan
  • Large mixing bowl
  • whisk
  • Measuring spoon
  • Measuring cup


  • 4 Tablespoons melted butter
  • ½ cup brown sugar
  • 1 (16 ounce) loaf of brioche bread, sliced
  • 9 eggs
  • 1 cup whole milk
  • ½ cup maple syrup
  • 1 Tablespoon vanilla extract
  • 1 ½ teaspoons ground cinnamon
  • ¼ teaspoon salt


  • Pour the melted butter into the bottom of a 9x13 baking dish. Sprinkle the brown sugar over the bottom of the dish.
    4 Tablespoons melted butter, ½ cup brown sugar
  • Cut the slices of brioche in half and then arrange the bread slices in the casserole pan. It is okay if they overlap a little bit. I like to try to line then up, laying one slightly on top of the next.
    1 (16 ounce) loaf of brioche bread, sliced
  • In a medium sized bowl, whisk together the eggs, milk, maple syrup, vanilla extract, cinnamon and salt.
    9 eggs, 1 cup whole milk, ½ cup maple syrup, 1 Tablespoon vanilla extract, 1 ½ teaspoons ground cinnamon, ¼ teaspoon salt
  • Pour the egg mix over the bread in the casserole dish. Try to pour the egg mix over every piece of bread.
  • Let the brioche French toast casserole sit for about 30 minutes. This will let it really soak up the eggs, milk and delicious flavor.
  • Preheat the oven to 350 degrees F.
  • Cover the casserole loosely with foil then bake the casserole in the hot oven for 20 minutes. Remove the foil from the pan and bake for another 10 minutes.
  • Remove the casserole from the oven, slice and serve while warm.
