Ingredients Method

Ingredients
  

  • 6 cups bread (Italian, brioche, or challah) cubed
  • 5 eggs
  • 1¼ cup milk (whole or low-fat)
  • ⅓ cup granulated sugar
  • ¼ cup brown sugar
  • 1 tsp ground cinnamon
  • 1 tsp vanilla extract
  • ¼ tsp nutmeg
  • ¼ cup heavy cream optional for extra creaminess
For the Topping (Optional but Recommended)
  • ¼ cup brown sugar
  • ¼ cup granulated sugar
  • ¼ cup cold butter, cubed
  • 1 tsp ground cinnamon

Method
 

Prepare the Casserole:
  1. Lightly grease a 9x13-inch baking dish.. Spread the cubed bread evenly in the dish.
  2. Make the Custard: In a large mixing bowl, whisk together eggs, milk, heavy cream (optional), sugars, vanilla extract, cinnamon, and nutmeg until well combined.
  3. Assemble: Pour the custard mixture evenly over the bread cubes, ensuring all pieces are soaked. Gently press down on the bread to help it absorb the liquid.
  4. Chill: Cover the dish tightly with plastic wrap or foil and refrigerate overnight (at least 8 hours).
Prepare the Topping (Optional):
  1. In a small bowl, mix brown sugar, granulated sugar, cinnamon, and cold butter. Use a fork or your fingers to create a crumbly texture. Store in the refrigerator if preparing the night before. I prefer doing it the day of baking.
Bake:
  1. Preheat the oven to 350°F
  2. Remove the casserole from the refrigerator and let it sit at room temperature for 15-20 minutes while the oven preheats.
  3. Sprinkle the prepared topping evenly over the casserole (if using).
  4. Bake uncovered for 40-45 minutes, or until the top is golden brown and the custard is set in the center.
  5. Serve: Let the casserole cool for 5 minutes before serving. Serve with powdered sugar, syrup, fresh fruit, or a dollop of whipped cream
