Print Recipe

Soft, custardy bread soaked overnight in a rich custard and baked to fluffy perfection, topped with a simple, glossy maple glaze. Perfect for a fuss-free, comforting breakfast or brunch.

Ingredients

Scale
  • 6 cups thick-cut bread cubes (day-old brioche or challah preferred)
  • 4 large eggs, room temperature
  • 1 1/2 cups whole milk
  • 1/2 cup heavy cream
  • 1/2 cup granulated sugar
  • 2 tsp pure vanilla extract
  • 1/2 tsp ground cinnamon
  • Pinch of salt
  • 1/3 cup pure maple syrup
  • 2 tbsp unsalted butter, melted
  • Optional: pinch of cinnamon or nutmeg for glaze

Instructions

  1. Cube the bread into roughly 1-inch cubes and place evenly in a 9×13 inch baking dish.
  2. In a large mixing bowl, whisk together eggs, whole milk, heavy cream, granulated sugar, vanilla extract, cinnamon, and salt until smooth.
  3. Pour the custard evenly over the bread cubes and gently press down with a spatula to ensure absorption. Cover and refrigerate for at least 6 hours or overnight.
  4. Preheat oven to 350°F (175°C). Remove casserole from fridge and let sit at room temperature for 15-20 minutes.
  5. Bake uncovered for 45-50 minutes until the top is lightly golden and custard is set (a knife inserted should come out clean). Tent with foil if browning too quickly.
  6. While baking, melt butter in a small saucepan over low heat, stir in maple syrup and warm until glossy. Remove from heat.
  7. Once baked, drizzle the warm maple glaze evenly over the casserole. Let sit 5-10 minutes before serving.

Notes

Use day-old brioche or challah for best texture. Letting the casserole soak overnight is crucial for a fluffy custard texture. If using fresh bread, toast lightly to dry. For dairy-free, substitute almond or oat milk and coconut cream. Add nuts or berries before baking for texture and flavor variations. Avoid glazing too early to keep the maple glaze glossy.
