Ingredients
  

Casserole Base
  • 8 slices brioche or challah bread thick cut
  • 6 large eggs
  • 1.5 cups heavy cream
  • 0.5 cup whole milk
  • 0.33 cup maple syrup
  • 2 tsp vanilla extract
  • 1 tsp ground cinnamon
  • 0.25 tsp salt
Topping
  • 3 tbsp butter melted
  • 2 tbsp brown sugar

Equipment

  • 9x13 inch baking dish
  • Large mixing bowl
  • Whisk
  • Measuring cups

Method
 

  1. Grease a 9x13 inch baking dish with butter and arrange bread slices in a single layer, overlapping slightly if necessary.
  2. In a large bowl, whisk together eggs, heavy cream, milk, maple syrup, vanilla extract, cinnamon, and salt until completely smooth.
  3. Pour custard mixture evenly over bread slices, ensuring each piece is thoroughly soaked. Press down gently to help absorption.
  4. Cover tightly with plastic wrap and refrigerate for at least 4 hours or overnight for best results.
  5. Remove from refrigerator 30 minutes before baking and preheat oven to 350°F (175°C).
  6. Remove plastic wrap, drizzle with melted butter, and sprinkle with brown sugar.
  7. Bake for 45-50 minutes until golden brown on top and set in center with no liquid custard remaining.
  8. Let cool for 5-10 minutes before serving with warm maple syrup.

Notes

Can be assembled up to 24 hours ahead. For extra richness, substitute half-and-half for milk. Serve with fresh berries, powdered sugar, or additional maple syrup.
