This cozy overnight gingerbread French toast casserole is what happens when a stranger’s kitchen wisdom meets my obsession with make-ahead breakfasts. It’s got all the warm, spicy notes of gingerbread cookies, but it’s soft, custardy, and completely forgiving.
Day-old brioche or challah is key for best texture. Don’t skip the overnight soakโ8 hours minimum, 12 is better. Room temperature eggs blend more smoothly. Grease the baking dish to prevent sticking. For dairy-free, use oat milk and coconut cream. For gluten-free, use gluten-free bread and flour blend.
