Instructions

Prepare the bread and apples: Cut the brioche loaf into 1-inch cubes and let it sit out for a short time to dry slightly, which helps it absorb the custard better. Peel and dice the apples into small pieces for layering.
Make the custard: In a large mixing bowl, whisk together the eggs, whole milk, granulated sugar, half of the brown sugar (1/4 cup), vanilla extract, cinnamon, and nutmeg until smooth and well combined.
Assemble the casserole: Grease a 9×13-inch baking dish. Layer half of the cubed bread, half of the diced apples, and sprinkle with 1/4 cup of brown sugar. Repeat the layers with the remaining bread, apples, and brown sugar to build a flavorful base.
Soak the bread: Pour the custard mixture evenly over the layered bread and apples, pressing down gently to ensure the bread cubes absorb the liquid. Drizzle the melted butter evenly on top to add richness and promote browning.
Chill the casserole: Cover the baking dish with plastic wrap or foil and refrigerate for at least 2 hours, or preferably overnight. This resting time allows the custard to fully soak into the bread for a tender texture.
Bake the casserole: Preheat the oven to 350°F (175°C). Bake the casserole covered for 30 minutes, then remove the cover and bake for an additional 20 to 25 minutes until the top is golden brown and the custard is set.
Finish and serve: Allow the casserole to cool for 5 to 10 minutes after baking. Dust the top with powdered sugar and serve warm with a drizzle of maple syrup for a sweet, comforting breakfast treat.

Notes

For best results, use day-old brioche bread or let fresh brioche dry out slightly to absorb the custard better.
This casserole can be assembled the night before and refrigerated, making it perfect for busy mornings or brunch gatherings.
You can substitute apples with pears or other firm fruits if preferred.
For a dairy-free version, substitute whole milk with almond or oat milk and use a non-dairy butter alternative.
Ensure the casserole is baked covered initially to prevent the custard from drying out, then uncovered for browning.
