Ingredients
  

Casserole Base
  • 1 loaf (16 oz) day-old French bread or challah cut into 1-inch cubes
  • 8 large eggs
  • 2 cups whole milk
  • 1/2 cup heavy cream
  • 1/2 cup granulated sugar
  • 1/4 cup brown sugar packed
  • 2 teaspoons vanilla extract
  • 1 teaspoon cinnamon
  • 1/2 teaspoon salt
  • 2 cups fresh or frozen blueberries not thawed
Topping
  • 1/2 cup all-purpose flour
  • 1/2 cup brown sugar packed
  • 1/4 cup cold unsalted butter cut into small pieces
  • 1/2 teaspoon cinnamon

Equipment

  • 9x13 inch baking dish
  • Large bowl
  • Whisk
  • Measuring cups and spoons

Method
 

Preparation
  1. Lightly grease a 9x13 inch baking dish, then arrange the bread cubes evenly in the pan.
  2. In a large bowl, whisk together eggs, milk, heavy cream, sugars, vanilla, cinnamon, and salt until well combined.
  3. Pour the egg mixture over the bread, ensuring all pieces are thoroughly soaked, and then sprinkle the blueberries over the top.
  4. For the topping, combine flour, brown sugar, and cinnamon in a small bowl, then cut in the cold butter until the mixture resembles coarse crumbs.
  5. Evenly sprinkle the prepared topping over the blueberry French toast casserole.
  6. Cover and refrigerate for at least 30 minutes, or preferably overnight, to allow the bread to fully absorb the custard.
Baking
  1. Preheat your oven to 375°F (190°C), then bake the casserole uncovered for 45-50 minutes, or until it's golden brown and set in the center.
  2. Let the casserole rest for a few minutes before serving, optionally topped with powdered sugar or maple syrup.

Notes

For best results, allow the casserole to soak overnight in the refrigerator for maximum flavor absorption and a richer texture.
