A cozy and indulgent holiday breakfast casserole soaked overnight in a rich eggnog custard with warm spices, perfect for busy mornings and festive gatherings.
If edges brown too quickly, tent with foil halfway through baking. Use sturdy bread like brioche or challah for best soak. Eggs should be room temperature for smooth custard. For dairy-free, use almond or coconut milk eggnog and substitute butter with coconut oil or vegan margarine. Variations include adding nuts, berries, or chocolate chips. Leftovers reheat well in microwave or oven wrapped in foil.
