A cozy, make-ahead friendly French toast casserole with pumpkin puree and warm spices. Soft custard center, slightly crispy edges, and an optional streusel topping make this the perfect fall breakfast or brunch.
For best results, use day-old sturdy bread like brioche or challah. Let the casserole rest after baking to allow the custard to set. To make ahead, assemble without streusel, cover, and refrigerate overnight. Let sit at room temperature for 20 minutes before baking. Add streusel after covered baking time.
