Instructions

1. Lightly grease a 9×13-inch baking dish. Arrange half of the bread cubes in the dish. Scatter half the blueberries over the bread, then layer with remaining bread and blueberries.
2. In a large bowl, whisk together eggs, milk, heavy cream, maple syrup, 1/4 cup sugar, vanilla extract, cinnamon, and salt until well combined.
3. Pour the custard evenly over the bread, pressing down slightly to help the bread absorb the liquid.
4. Cover the dish tightly with foil or plastic wrap and refrigerate overnight (or for at least 4 hours).
5. When ready to bake, preheat oven to 350°F (175°C). Uncover the casserole; sprinkle the top with the remaining 1/4 cup of sugar and drizzle with melted butter for a crisp, golden finish.
6. Bake for 45–50 minutes, or until puffed and golden brown. If the top browns too quickly, tent loosely with foil during the last 15 minutes.
7. Let cool for 10 minutes, then serve topped with powdered sugar, syrup, or lemon zest as desired.
