A cozy and easy holiday breakfast casserole featuring day-old brioche soaked in a creamy eggnog custard with warm spices, topped with a caramelized brown sugar and nut topping.
For best texture, use day-old brioche or challah bread. Toast fresh bread lightly if needed. Soaking overnight in the fridge improves flavor and texture. Tent with foil if edges brown too quickly. Can substitute plant-based milk and eggnog and use flax eggs for a vegan version. Add fruit or chocolate chips for variations.
