Brioche French toast casserole is the perfect breakfast to feed a crowd. Soft and fluffy on the inside with a golden brown cinnamon sugar topping. Serve with a blueberry compote and generously drizzle with maple syrup.



  • 1 loaf (14-16 ounces) butter brioche or challah bread

For the egg mixture:

  • 6 large eggs
  • 2 cups (50 cl) milk
  • 3/4 cup (20 cl) heavy cream
  • 1/2 cup (100g) sugar (optional)*
  • 1 teaspoon ground cinnamon

For sugar-cinnamon topping:

  • 1/2 cup (90g) packed brown sugar
  • 1/4 cup (30g) all-purpose flour
  • 1 teaspoon ground cinnamon
  • 4 Tablespoons (60g) unsalted butter, diced


For the brioche:

  1. Preheat the oven to 350°F (180°C) and grease a 9 x 13-inch (23×30 cm) baking pan.
  2. Cut brioche into cubes or tear into small pieces. Set aside.
  3. In a medium bowl, whisk together eggs, milk, heavy cream, sugar if using*, vanilla, and cinnamon. Add the brioche and stir until well combined.
  4. Let sit for about 10 minutes, stir again, then pour into the prepared baking dish. Set aside.

For the crisp:

  1. In a small bowl combine brown sugar, flour and cinnamon. Add the butter cut into small pieces and rub the mixture with your finger tips until it resembles small crumbs.
  2. Sprinkle over bread in the pan and bake for about 30 minutes, or until golden on top and cooked through (if it wiggles a lot it’s not done, continue to bake until it cooked through completely).
  3. Serve with maple syrup and an additional berry compote if desired.


* Because the brioche loaf is naturally sweetened, feel free to use less sugar in the egg mixture, or don’t use any at all to keep the sugar-cinnamon topping only. Also, remember that you will serve your French toast casserole with maple syrup.
