Instructions
Prepare the baking dish: Grease a 9x13-inch baking dish with butter or non-stick spray. Set aside.
Cube the brioche: Cut the brioche into 1-inch cubes. If it's slightly stale, even better—it’ll soak up the custard more effectively. Spread the cubes evenly in the prepared dish.
Make the custard: In a large mixing bowl, whisk together the eggs, milk, cream, granulated sugar, brown sugar, vanilla, cinnamon, nutmeg (if using), and salt until well combined.
Assemble the dish: Pour the custard evenly over the brioche cubes. Gently press the bread down so it soaks up the liquid. Cover the dish with foil or plastic wrap.
Chill (optional, but recommended): Refrigerate for at least 1 hour, or preferably overnight, to allow the bread to absorb the custard fully.
Preheat and bake: When ready to bake, preheat the oven to 175°C (350°F). Remove the dish from the fridge while the oven heats.
Bake uncovered: Bake uncovered for 40–50 minutes, or until the top is golden brown and the center is set but still soft. If it starts to brown too quickly, you can loosely cover it with foil for the last 10–15 minutes.
Cool slightly: Let it cool for about 10 minutes before serving.
Serve and enjoy: Dust with powdered sugar, drizzle with maple syrup, and top with berries or nuts if desired. Serve warm!
