A comforting and easy overnight French toast casserole featuring cinnamon and a buttery brown sugar topping, perfect for a cozy breakfast or brunch.
Use sturdy bread like brioche, challah, or Texas toast for best results. Letting the casserole soak overnight ensures a custardy texture without sogginess. Cover with foil if the top browns too quickly. Rest before serving for easier slicing. Optional add-ins include nuts or fresh berries. Gluten-free and vegan adaptations are possible with substitutions.
