What type of cheese is on top of the stuffed mushrooms?

The stuffed mushrooms at Olive Garden are topped with a blend of mozzarella, romano, and parmesan cheese, which contributes to both the flavor and texture of the dish. This combination of cheeses is typical in Italian cuisine, providing a rich, savory profile that complements the mushrooms nicely. Mozzarella offers a creamy texture, while romano adds a sharp, tangy bite, and parmesan brings in a nutty flavor, creating a delicious topping that enhances the overall experience of the stuffed mushrooms.

Other cheese options, such as feta, cheddar, or gorgonzola, do not appear in this specific dish. Feta is more commonly used in salads or Mediterranean dishes, cheddar has a stronger and often sharper flavor than what is traditionally used in such Italian-inspired appetizers, and gorgonzola presents a distinct blue cheese flavor that isn't part of the stuffed mushrooms at Olive Garden.
