Servings: 8 Servings
- 1 loaf thick-cut French brioche bread
- 6 large eggs
- 3½ cups half-and-half
- 3 –4 tablespoons sugar
- 1 tablespoon ground cinnamon
- 1½ teaspoons ground nutmeg
- Zest of 1 orange
- 1 tablespoon vanilla bean paste
The Night Before
Remove the crust from the brioche bread. Cut the bread into approximately 1-inch cubes and spread them evenly across your baking dish.
In a large mixing bowl, whisk together the eggs, half-and-half, sugar, cinnamon, nutmeg, orange zest, and vanilla until combined.
Pour the custard evenly over the cubed brioche.
Cover the baking dish tightly with plastic wrap and refrigerate overnight, allowing the bread to absorb the custard.
The Next Morning
Take the casserole out of the refrigerator at least 30 minutes before baking.
Preheat your oven to 350°F. Remove the plastic wrap before baking.
Place the uncovered casserole in the oven and bake for 45–50 minutes, until the custard is set and the top is golden.
Remove the casserole from the oven, tent it loosely with foil, and let it rest for approximately 30 minutes before serving.
Slice into pieces, and top with maple syrup and/or powder sugar. Enjoy!
