Tips & Tricks (5)

Day-Ahead Custard Soaking 🌙
Prepare the casserole the night before and refrigerate for 8-12 hours—this allows the brioche to fully absorb the custard mixture, creating a creamy, cohesive texture throughout rather than dry spots.
Quality Brioche Selection 🥐
Use day-old brioche that's slightly stale rather than fresh—the drier texture absorbs the egg custard better and prevents the casserole from becoming soggy or mushy.
Temperate Egg Mixture Method 🥚
Whisk eggs and milk together first, then slowly warm the mixture to room temperature before pouring over brioche—this prevents cooking the eggs prematurely and ensures an even, silky custard.
Brown Sugar Caramelization 🍯
Sprinkle brown sugar on top just before baking rather than mixing it in—it will caramelize and create a delicious crispy, golden crust that contrasts beautifully with the creamy interior.
Precise Oven Temperature & Timing ⏱️
Bake at 350°F for 40-50 minutes until the center is set but still slightly jiggly—overbaking dries it out, so use a toothpick inserted in the center as your guide for perfect doneness.
