This make-ahead eggnog French toast bake is a rich, custardy Christmas morning miracle. Soak thick bread in a creamy eggnog custard overnight, then bake for a golden, slightly crisp top and a soft, bread pudding-like interior.
Do not skip the overnight soak; it ensures the bread fully absorbs the custard. Use stale or day-old bread for best texture. Let the bake rest 10 minutes after baking to set properly. For a gluten-free version, use gluten-free brioche. For dairy-free, use dairy-free eggnog and butter substitute.
