Ingredients

Scale
  • 1 loaf thick-cut bread (brioche or challah), cubed
  • 6 large eggs, room temperature
  • 2 cups whole milk (or 2% milk for lighter option)
  • 1/2 cup heavy cream (optional)
  • 1/3 cup granulated sugar
  • 2 tsp pure vanilla extract
  • 1 tsp ground cinnamon
  • 1/4 tsp salt
  • Butter, for greasing the baking dish
  • 2 cups mixed fresh or frozen berries (blueberries, raspberries, blackberries)
  • 1/4 cup granulated sugar (adjust to taste)
  • 1 tbsp fresh lemon juice
  • 1/2 tsp ground cinnamon (optional)
  • 1 tsp cornstarch mixed with 1 tbsp cold water (to thicken)

Instructions

  1. Grease a 9×13-inch baking dish with butter. Cube the bread into roughly 1-inch pieces and spread evenly in the dish.
  2. In a large bowl, whisk together eggs, milk, heavy cream (if using), sugar, vanilla extract, cinnamon, and salt until smooth.
  3. Pour the custard evenly over the bread cubes, pressing gently to soak all pieces. Cover tightly with plastic wrap or foil.
  4. Refrigerate for at least 6 hours or overnight to allow the custard to soak in.
  5. About 30 minutes before baking, combine berries, sugar, lemon juice, and cinnamon in a medium saucepan. Cook over medium heat, stirring occasionally, until berries break down and mixture simmers (8-10 minutes). Stir in cornstarch slurry and cook for another minute until thickened. Remove from heat and set aside.
  6. Preheat oven to 350°F (175°C). Remove plastic wrap and bake casserole uncovered for 45-50 minutes until top is golden brown and custard is set (toothpick inserted comes out clean).
  7. Let casserole cool for 5-10 minutes. Spoon warm berry compote over servings. Optionally dust with powdered sugar or drizzle with maple syrup.
  8. If casserole is too soggy, use slightly stale bread next time. If edges brown too fast, tent loosely with foil halfway through baking.

Notes

Use day-old or slightly stale bread for best custardy texture. Let casserole soak overnight for optimal results. Preheat oven fully before baking. Berry compote can be made ahead and stored refrigerated for up to a week. For dairy-free, use almond milk and coconut cream. Gluten-free bread can be substituted.
