Ingredients

For the Casserole

• 1 loaf day-old French bread or brioche, cubed (about 12–14 cups)

• 3 medium apples, peeled, cored, and diced

• 8 large eggs

• 2 ½ cups milk (600ml)

• ½ cup heavy cream (120ml, optional)

• ½ cup pure maple syrup (120ml) or brown sugar

• 2 teaspoons vanilla extract

• 2 teaspoons cinnamon

• ¼ teaspoon nutmeg

• Pinch of salt

Cinnamon Sugar Topping

• ¼ cup brown sugar (50g)

• 2 tablespoons granulated sugar (25g)

• 1 ½ teaspoons cinnamon

• 3 tablespoons melted butter (45g)

For Serving

• Maple syrup

• Powdered sugar

• Optional sautéed apples

Instructions

1. Prep the Dish

   Grease a 9×13-inch (23×33 cm) baking dish. Add cubed bread and diced apples, tossing gently to distribute evenly.

2. Make the Custard

   In a large bowl, whisk together eggs, milk, cream (if using), maple syrup, vanilla, cinnamon, nutmeg, and salt.

3. Assemble

   Pour the custard evenly over the bread and apples. Gently press down so the bread absorbs the mixture.

4. Chill (Optional)

   Let sit for 30 minutes, or cover and refrigerate overnight for a deeper flavor and a softer texture.

5. Make the Topping

   Mix brown sugar, granulated sugar, and cinnamon. Stir in melted butter until crumbly.

6. Bake

   Preheat oven to 350°F (175°C). Sprinkle topping evenly over casserole. Bake 40–50 minutes, until golden and set in the center.

7. Serve

   Cool for 10–15 minutes before serving. Dust with powdered sugar and drizzle with maple syrup.

Tips & Variations

• Use day-old bread for the best texture and absorption

• Choose Granny Smith for tart flavor or Honeycrisp for sweetness

• Reduce the maple syrup slightly for a less sweet version

• Tent with foil if browning too quickly

• Add chopped pecans or walnuts for crunch
