A rich, custardy French toast casserole made with eggnog, perfect for holiday mornings. Prep it the night before and bake it in the morning for a warm, cozy breakfast that will convert even the biggest eggnog skeptics.
Use day-old bread for best texture. The overnight soak is essential for the custard to fully penetrate the bread. If the topping browns too quickly, tent with foil. Let the casserole rest before serving to allow the custard to set. For a dairy-free version, use dairy-free eggnog and substitute butter with melted coconut oil. For a gluten-free version, use sturdy gluten-free bread and add 10 minutes to baking time.
