  • Casserole:
  • 1 loaf brioche bread cubed
  • 1 cup fresh blueberries divided (Plus more for serving)
  • 8 large eggs
  • 2 1/4 cups whole milk
  • 3/4 cup brown sugar
  • 1/2 tsp ground cinnamon
  • 1 tbsp vanilla extract

  • Streusel Topping:
  • 1/3 cup brown sugar
  • 1/3 cup flour
  • 1/2 tsp cinnamon
  • 6 tbsp unsalted butter cold and cubed

  • Serve with:
  • Maple Syrup
  • Powdered sugar
  • Fresh blueberries


  • Prepare the casserole, by greasing a 9 x 13 inch pan with cooking spray.
  • Cut the bread into cubes, about 1 inch in size.
  • Spread half of the cubes into the prepared baking pan and top evenly with half of the blueberries.
  • Add the remaining bread cubes followed by the remaining blueberries. Set aside.
  • Whisk the eggs, milk, brown sugar, cinnamon, and vanilla together until very smooth.
  • Pour evenly over the bread.
  • Cover the pan very tightly with plastic wrap and place in the refrigerator for at least 3 hours - overnight. Overnight is best.
  • Preheat oven to 350 degrees. Remove pan from the refrigerator and uncover.
  • Prepare the topping, by whisking the brown sugar, flour, and cinnamon together in a medium bowl.
  • Cut in the cubed butter with a pastry blender until crumbly.
  • Sprinkle the topping evenly over the soaked bread.
  • Bake for 50-60 minutes or until golden brown on top. Serve immediately.
  • Cover the cooled leftovers tightly and store in the refrigerator for 2-3 days. Enjoy!
