Ingredients Method Notes

Ingredients
  

  • 1 loaf (about 1 pound) day-old challah or brioche bread, cut into 1-inch cubes
  • 8 large eggs
  • 2 cups whole milk
  • 1/2 cup heavy cream
  • 1/2 cup granulated sugar
  • 2 teaspoons pure vanilla extract
  • 1 teaspoon ground cinnamo
  • 1/4 teaspoon nutmeg
  • 1/4 teaspoon salt
  • 3 cups mixed berries (fresh or frozen, thawed if frozen)
  • 2 tablespoons unsalted butter, melted
  • 2 tablespoons brown sugar
  • Powdered sugar (for dusting, optional)
  • Maple syrup (for serving, optional)

Method
 

  1. Lightly grease a 9x13-inch baking dish with butter or non-stick spray.
  2. Cut the day-old bread into 1-inch cubes and distribute evenly in the prepared baking dish.
  3. Scatter the mixed berries over the bread cubes.
  4. In a large bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, nutmeg, and salt until smooth.
  5. Pour the custard mixture evenly over the bread and berries, pressing down gently to ensure all pieces are soaked.
  6. Cover the baking dish tightly with plastic wrap and refrigerate for at least 4 hours, preferably overnight.
  7. Preheat the oven to 375°F (190°C). Remove the casserole from the refrigerator while the oven preheats.
  8. In a small bowl, combine the melted butter and brown sugar, then drizzle over the top of the casserole.
  9. Bake for 45-55 minutes until golden brown and puffed, with a clean knife inserted into the center.
  10. Let the casserole rest for 5-10 minutes before serving, dust with powdered sugar if desired, and serve warm with maple syrup.

Notes

Use day-old bread for best results. Soak overnight for optimal flavor and texture. Adjust berries and spices to your preference.
