What specialty dish features mushrooms and Marsala sauce?

The specialty dish that features mushrooms and Marsala sauce is Chicken Marsala. This dish is well known for its rich flavors, as the Marsala wine enhances the taste profile of the chicken, while the sautéed mushrooms add a savory depth. The combination creates a comforting and indulgent dish that is a staple on the menu.

In contrast, Eggplant Parmesan is typically made with breaded and fried eggplant slices, layered with marinara sauce and cheese, so it does not include mushrooms or Marsala. Pasta Primavera is primarily a pasta dish that focuses on seasonal vegetables, and while it may have various sauces, it does not feature Marsala sauce or mushrooms as a key component. Fettuccine Alfredo is a creamy pasta dish made with a sauce based on butter and Parmesan cheese, and it does not incorporate mushrooms or Marsala wine. Therefore, Chicken Marsala is distinct in its use of both mushrooms and Marsala sauce, making it the correct answer.
