Lightly grease a 9x13-inch baking dish. Arrange half of the cubed bread in the dish and scatter cream cheese cubes over it.
Top with fresh blueberries and then layer with the remaining bread cubes.
In a large bowl, whisk together the eggs, milk, vanilla extract, and maple syrup until fully combined.
Pour the egg mixture evenly over the bread cubes, ensuring all pieces are soaked.
Cover the dish and refrigerate overnight to let the bread absorb the custard mixture.
Take the casserole out of the refrigerator 30 minutes before baking. Preheat the oven to 350°F (175°C).
Bake the casserole, covered, for 30 minutes. Then uncover and continue baking for an additional 25-30 minutes, or until the center is firm and the top is lightly browned.
While the casserole bakes, prepare the sauce. In a medium saucepan, combine the sugar, water, and cornstarch. Bring to a boil, stirring constantly for 3-4 minutes. Stir in the fresh blueberries, reduce the heat, and simmer for about 10 minutes, or until the blueberries burst. Stir in butter until melted and smooth.
Once the casserole is baked, serve individual portions on plates and drizzle with the warm blueberry sauce.
Notes
You can prep this casserole the night before, making it perfect for busy mornings or holiday brunches. Just remember to take it out of the fridge 30 minutes before baking to prevent it from being too cold when it goes into the oven.
Leftovers can be stored in the refrigerator for up to 3 days. Reheat in the microwave or oven before serving.
