Ingredients

Scale
  • 8 cups cubed day-old French bread or brioche
  • 8 large eggs, room temperature
  • 2 cups whole milk or 2%
  • 1 cup heavy cream
  • ½ cup granulated sugar
  • 2 teaspoons vanilla extract
  • 1 tablespoon ground cinnamon (divided)
  • ¼ teaspoon salt
  • 6 tablespoons unsalted butter, cold and cubed
  • ½ cup packed light brown sugar
  • ½ cup all-purpose flour
  • Optional: 1 teaspoon ground nutmeg or cardamom

Instructions

  1. Cube about 8 cups of day-old French bread or brioche into roughly 1-inch pieces. Spread on a baking sheet and let dry slightly if too fresh (about 10 minutes).
  2. In a large bowl, whisk together 8 large eggs, 2 cups whole milk, 1 cup heavy cream, ½ cup granulated sugar, 2 teaspoons vanilla extract, 1 tablespoon ground cinnamon, and ¼ teaspoon salt until smooth.
  3. Place the bread cubes into a 9×13-inch baking dish. Pour the custard evenly over the bread, pressing gently to soak all pieces. Cover tightly with plastic wrap or foil and refrigerate overnight or at least 6 hours.
  4. The next morning, mix ½ cup light brown sugar, ½ cup all-purpose flour, 3 tablespoons cold cubed unsalted butter, and 1 teaspoon ground cinnamon in a bowl. Use a pastry cutter or fork to blend until coarse crumbs form.
  5. Preheat oven to 350°F (175°C). Remove casserole from fridge and sprinkle streusel topping evenly over the soaked bread.
  6. Bake uncovered for 45-50 minutes until the top is golden brown and custard is set but still soft in the center. A toothpick inserted should come out clean but moist.
  7. Let the casserole rest for 10 minutes before serving.

Notes

Use day-old or stale bread to avoid sogginess. Cover casserole tightly overnight to keep flavors melding and prevent drying out. Make streusel topping right before baking to keep it crunchy. Tent with foil if top browns too fast. Let rest 10 minutes before serving.
