Asiago cheese is an excellent addition to alfredo sauce. It melts just as easily as parmesan cheese and, as aforementioned, is a bit milder in taste, which adds complexity to the sauce's flavor. Try grating half asiago and half parmesan into your next batch of alfredo sauce.
Asiago is also a great bagel topping; most Bagel Cafe and Panera locations sell asiago-topped bagels. The cheese is an invaluable tangy complement to the bland bagel dough. It coats the bagel almost entirely during the baking process and melts around the edges and the inside to create a phenomenon best described as "asiago crunchies."
