A cozy and fuss-free French toast casserole featuring thick-cut brioche soaked in a creamy custard and fresh mixed berries, perfect for breakfast or brunch.

Ingredients

Scale
  • 1 loaf thick-cut brioche or challah bread, cubed (about 8 cups)
  • 6 large eggs, room temperature
  • 2 cups whole milk (can substitute almond or oat milk for dairy-free)
  • 1 cup heavy cream (can substitute coconut cream if needed)
  • 1/3 cup granulated sugar
  • 2 teaspoons pure vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon fine sea salt
  • 2 cups mixed fresh berries (blueberries, sliced strawberries, raspberries)
  • 2 tablespoons unsalted butter, melted
  • Powdered sugar for dusting (optional)

Instructions

  1. Cube the brioche or challah into roughly 1-inch pieces and place them evenly in a greased 9×13-inch baking dish.
  2. In a large bowl, whisk together eggs, whole milk, heavy cream, sugar, vanilla extract, cinnamon, and salt until well combined and slightly frothy (about 2-3 minutes).
  3. Pour the custard mixture evenly over the bread cubes. Gently press the bread down to soak up the custard. Let sit at room temperature for 10 minutes to absorb fully.
  4. Gently fold in 1 1/2 cups of fresh berries into the soaked bread mixture, reserving 1/2 cup for topping.
  5. Preheat oven to 350°F (175°C). Cover the dish loosely with aluminum foil and bake for 35 minutes.
  6. Remove the foil and bake for an additional 15-20 minutes until the top is golden and custard is set (a knife inserted should come out clean).
  7. Remove from oven and let rest for 5 minutes. Top with reserved berries and dust with powdered sugar before serving. Optionally, drizzle with maple syrup.

Notes

Do not skip the soaking step to avoid dry edges. Drain very juicy berries to prevent sogginess. Cover casserole with foil during first half of baking to trap steam and set custard, then remove foil to brown the top. For a crispy top, brush melted butter or sprinkle brown sugar before final bake.
