Ingredients

• 8 slices Thick-cut bread (such as brioche or challah)
• 6 large Eggs
• 2 cups Half-and-half
• 1 tablespoon Granulated sugar
• 1 teaspoon Vanilla extract
• 1 cup Orange marmalade
• 2 tablespoons Butter, melted
• 1 teaspoon Ground cinnamon
• 1 tablespoon Powdered sugar (optional, for garnish)
• 1 cup Fresh berries (optional, for serving)
• 0.5 cup Maple syrup (for serving)

Directions

Step 1

Grease a 9x13-inch baking dish with butter or nonstick cooking spray.

Step 2

Arrange the slices of bread in a single layer in the dish, slightly overlapping if necessary.

Step 3

In a large mixing bowl, whisk together the eggs, half-and-half, granulated sugar, vanilla extract, and ground cinnamon until well combined.

Step 4

Spread the orange marmalade in an even layer across the top of the bread slices.

Step 5

Pour the egg mixture over the bread and marmalade, ensuring all the bread is evenly soaked.

Step 6

Cover the dish tightly with plastic wrap or aluminum foil and refrigerate overnight, or at least 6 hours, to allow the flavors to meld and the bread to absorb the liquid.

Step 7

Preheat the oven to 350°F (175°C).

Step 8

Drizzle the melted butter evenly over the top of the casserole.

Step 9

Bake the casserole, uncovered, for 40 to 45 minutes, or until the top is golden brown and the center is set but springy to the touch.

Step 10

Remove the casserole from the oven and let it rest for 5 to 10 minutes before serving.

Step 11

Optionally, dust the top with powdered sugar and garnish with fresh berries.

Step 12

Serve warm with maple syrup drizzled over individual portions.
