The clean, grassy flavor of asparagus shines through in this easy pasta dish. Creamy ricotta cheese adds a sense of indulgence without overpowering the asparagus. The sunny lemon keeps things bright even as the pasta gives it that cozy feeling. In short, it's a dinner perfect for those nights when it's cool enough to want something warm but spring enough to want something fresh. Using fresh pasta lets this dish shine. Long, tangled tagliatelle noodles are a good choice, as are fresh lasagna noodles cut into floppy squares. If all you have is dried pasta, though, it's still tasty. Fettucine or fusilli are both good choices.
