Ingredients

Scale
  • 8 cups thick-cut bread cubes (day-old brioche or challah preferred)
  • 3 cups fresh peaches, peeled and sliced (frozen peaches thawed and drained can be used)
  • 6 large eggs, room temperature
  • 2 cups whole milk (can substitute almond or oat milk)
  • 1 cup heavy cream
  • ½ cup granulated sugar
  • 2 teaspoons vanilla extract
  • 2 teaspoons ground cinnamon (divided between custard and streusel)
  • ½ teaspoon salt
  • 6 tablespoons unsalted butter, cold and cubed (for streusel)
  • ¾ cup all-purpose flour (can use gluten-free flour)
  • ½ cup packed brown sugar
  • Optional: pinch of nutmeg in custard

Instructions

  1. Preheat oven to 350°F. Lightly grease a 9×13-inch baking dish.
  2. Cube 8 cups of day-old bread into roughly 1-inch pieces and spread evenly in the baking dish.
  3. Peel, pit, and slice 3 cups of peaches, then scatter over the bread cubes.
  4. In a large bowl, whisk together 6 eggs, 2 cups whole milk, 1 cup heavy cream, ½ cup granulated sugar, 2 teaspoons vanilla extract, 1 teaspoon ground cinnamon, ½ teaspoon salt, and a pinch of nutmeg if using until smooth.
  5. Slowly pour the custard mixture evenly over the bread and peaches, pressing gently to help soak. Let sit for 10 minutes at room temperature.
  6. In a small bowl, combine ¾ cup flour, ½ cup brown sugar, 1 teaspoon ground cinnamon, and 6 tablespoons cold butter cubes. Use a pastry cutter or fingers to mix until coarse crumbs form.
  7. Sprinkle the cinnamon streusel evenly over the soaked bread and peaches.
  8. Cover loosely with foil and bake for 35 minutes.
  9. Remove foil and bake an additional 15-20 minutes until the top is golden and custard is set.
  10. Let rest for 10 minutes before serving. Serve warm with maple syrup, powdered sugar, or whipped cream if desired.

Notes

Use day-old bread to avoid mushiness. Do not soak bread in custard for more than 10 minutes unless refrigerating overnight. Keep butter cold for a crumbly streusel. Rotate casserole midway through baking for even browning. Let rest before serving for easier slicing. Can refrigerate assembled casserole overnight and bake in the morning with slightly increased baking time.
