A make-ahead Christmas morning breakfast featuring brioche soaked in eggnog custard, topped with a buttery pecan streusel. It’s rich, cozy, and perfect for feeding a crowd with minimal morning effort.
Use stale bread for best texture. If top browns too quickly, tent with foil for last 10-15 minutes. Let rest after baking to allow custard to set. Leftovers keep refrigerated for up to 3 days; reheat in a 300°F oven for 10-15 minutes.
