For an intensified mushroom flavor, consider using dried porcini mushrooms. Rehydrate them in warm water, chop, and add them to the roasting mix. The quality of the bacon significantly impacts the overall taste. Opt for thick-cut, applewood-smoked bacon for the best results. Feel free to experiment with different types of cheeses. Provolone, mozzarella, or even a sprinkle of Parmesan would be delightful additions.
