A rich and elegant French toast casserole with a silky custard base and a crispy caramelized sugar crust, perfect for brunch or holiday mornings.
Use day-old brioche or challah for best custard absorption without sogginess. Soak bread at least 4 hours or overnight for best texture. Use a kitchen torch for even caramelization; broiler can be used but requires close attention. Let casserole rest after baking for the sugar crust to harden. For dairy-free, substitute heavy cream and milk with full-fat coconut milk and use dairy-free bread. Gluten-free bread can be used as an alternative.
