What are some seasonings that can spice up a bland frozen chicken alfredo?
Well, an Alfredo sauce is supposed to taste mostly buttery, with the addition of the umami taste that comes from Parmesan. You could always add spicy stuff to it, but that will change the taste into something completely different. If you want to stay true to the basics of an alfredo dish, try adding a handful of freshly grated Parmesan and (to add to the rich umami taste) some chopped sundried tomatoes. Herbs that go well with this dish are oregano and sage.
