Prep the Bread: Preheat your oven to 350°F (175°C). Grease a 9x13 inch baking dish with butter or cooking spray. Place the cubed brioche bread evenly in the dish.
Make the Custard: In a large mixing bowl, whisk together the pumpkin puree, eggs, whole milk, heavy cream, brown sugar, vanilla extract, cinnamon, nutmeg, ginger, and salt until well combined and smooth.
Combine: Pour the pumpkin custard mixture evenly over the cubed bread, ensuring all pieces are soaked well. If using, sprinkle the chopped pecans over the top for added crunch.
Soak: Cover the baking dish with plastic wrap and refrigerate for at least 30 minutes, or preferably overnight. This allows the bread to absorb the custard.
Bake: Once ready to bake, remove the dish from the refrigerator. Bake in the preheated oven for 40-45 minutes or until the top is golden brown and the custard is set.
Cool and Serve: Allow the bake to cool for about 10 minutes before slicing. Serve warm, drizzled with maple syrup and a dusting of powdered sugar for that sweet finishing touch.
Notes
