Tips & Tricks (5)

Brioche Bread Selection 🍞
Choose day-old or slightly stale brioche for the best texture, as it will absorb the custard more evenly without falling apart.
Custard Infusion Technique 🥛
Let the bread soak in the custard mixture for at least 30 minutes (or overnight) to ensure maximum flavor penetration and a custardy interior.
Cinnamon Topping Trick 🌟
Create a crispy cinnamon-sugar streusel topping by mixing brown sugar, flour, and cold butter to sprinkle over the casserole before baking.
Baking Moisture Magic 💧
Cover the casserole with foil for the first half of baking to prevent over-browning and maintain a moist, custardy texture.
Make-Ahead Mastery 🕰️
Assemble the casserole the night before and refrigerate, allowing the flavors to meld and making morning preparation a breeze.
