A custardy, slightly sweet, and forgiving breakfast dish that can be prepped the night before, perfect for holiday mornings.

Ingredients

Scale
  • 1 loaf bread, preferably brioche or challah (day old is best; stale works great)
  • 6 large eggs
  • 2 cups milk (whole milk for creaminess; swap for plant milk in a pinch)
  • 1 cup heavy cream (can use additional milk for a lighter version)
  • 1/2 cup brown sugar
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1 cup mixed berries (blueberries, strawberries, raspberries), for serving
  • Crumble topping:
  • 1/2 cup brown sugar
  • 1/4 cup all purpose flour
  • 1/4 cup butter, cold and cubed
  • 1 teaspoon ground cinnamon

Instructions

  1. Grease a 9 by 13 inch baking dish with butter or nonstick spray.
  2. Cut the loaf into roughly 1 to 1.5 inch cubes. Place half the cubes evenly in the bottom of the dish.
  3. In a large bowl, whisk eggs until combined. Add milk, heavy cream, 1/2 cup brown sugar, vanilla, 1 teaspoon cinnamon, and salt. Whisk until smooth.
  4. Pour half of the custard mixture over the bread in the dish, pressing gently so the bread soaks some liquid.
  5. Add the remaining bread cubes on top, then pour the remaining custard over everything. Press lightly so the custard soaks in.
  6. Cover tightly with plastic wrap and refrigerate overnight, or at least 6 hours.
  7. When ready to bake, preheat oven to 350°F (175°C).
  8. Make the crumble by combining 1/2 cup brown sugar, 1/4 cup flour, 1 teaspoon cinnamon, and the cold cubed butter. Use a pastry cutter or your fingers to rub until the mixture forms coarse crumbs.
  9. Sprinkle the crumble evenly over the soaked casserole.
  10. Bake for 45 to 50 minutes, until the top is golden and the center is set.
  11. Let the casserole sit for 5 minutes, then serve warm topped with mixed berries.

Notes

For a nutty twist, sprinkle chopped pecans or sliced almonds into the crumble. You can also add a teaspoon of orange zest to the custard for added flavor.
