Instructions

Preheat oven to 350°F (175°C). Lightly grease a 9x9-inch (23x23 cm) baking dish with 2 tbsp melted butter.
Place the brioche cubes and 1 cup of fresh blueberries in a large mixing bowl and gently toss to combine.
In a separate bowl, whisk together the eggs, whole milk, pure vanilla extract, granulated sugar, ground cinnamon, fine sea salt, and 1/2 tsp ground nutmeg until smooth.
Pour the custard evenly over the brioche and blueberries, stirring gently to coat all pieces. Let soak for 10 minutes to allow the bread to absorb the custard.
In a small bowl, combine the flour, light brown sugar, remaining 1/2 tsp cinnamon, remaining 1/4 tsp nutmeg, chopped nuts, and remaining 2 tbsp melted butter. Stir until mixture resembles coarse crumbs to make the streusel topping.
Transfer the soaked brioche and blueberry mixture into the prepared baking dish, spreading evenly.
Sprinkle the streusel mixture evenly over the top of the casserole.
Bake uncovered for 30 to 35 minutes, or until the custard is set and the streusel is golden and crisp.
Remove from oven and let cool for 5 minutes before serving.

Tips

Use day-old brioche to ensure it soaks up the custard without becoming mushy.
Add a vanilla bean pod scraped into the custard for deeper vanilla flavor instead of vanilla extract.
