A simple, overnight French toast bake made with eggnog, brioche, and a crunchy streusel topping. Perfect for holiday mornings with minimal prep and maximum flavor.
Use day-old bread for best texture. If using fresh bread, spread cubes on a baking sheet and let dry for 1-2 hours. For dairy-free, use plant-based eggnog and substitute butter with coconut oil or vegan butter. For gluten-free, use gluten-free bread and all-purpose flour blend. Add 2 tablespoons dark rum or bourbon for an adult version. Leftovers keep in the refrigerator for up to 3 days; reheat in oven at 300°F for 10 minutes.
