Ingredients
  

For the Casserole
  • 14 ounces brioche bread, cut into 1-inch cubes About one standard loaf. Slightly stale brioche absorbs custard better; if fresh, toast cubes lightly for better texture.
  • 6 large eggs For the custard base.
  • 1.5 cups heavy cream Provides richness.
  • 0.5 cup milk Whole or 2% is fine; can swap with plant-based milk for a dairy-free option.
  • 0.5 cup granulated sugar Can reduce by 2 tablespoons for less sweetness, or use light brown sugar for a hint of molasses.
  • 1 tablespoon vanilla extract Enhances flavor.
  • 0.5 teaspoon ground cinnamon For added spice.
  • 1 pinch ground nutmeg Adds warmth.
  • 1 pinch kosher salt Balances sweetness.
  • Powdered sugar for dusting For serving.

Method
 

Preparation
  1. Spray a 3-quart baking dish with non-stick spray.
  2. Cube the brioche into 1-inch pieces and spread evenly in the prepared dish.
  3. In a large bowl, whisk the eggs until blended.
  4. Add heavy cream, milk, sugar, vanilla, cinnamon, nutmeg, and salt; whisk until smooth and combined.
  5. Pour the custard evenly over the brioche and press the bread gently to absorb the liquid.
  6. Cover the dish with plastic wrap and chill in the refrigerator overnight, or for at least 6 hours.
Baking
  1. Preheat the oven to 350°F (175°C).
  2. Remove plastic wrap and place the dish in the oven; bake for 45 to 60 minutes until the top is golden brown and a knife comes out mostly clean.
  3. Let rest for 10 minutes before dusting with powdered sugar and serving.
