This satisfying one-pot pasta cooks with just the right amount of water so you're left with perfectly cooked noodles and enough starchy liquid to act as a sauce. Stir in lemon juice and zest at the end for a bright finish.
Combine water, pasta, oil and salt in a large Dutch oven or heavy pot. Bring to a rolling boil over high heat, then reduce heat to medium and simmer uncovered, stirring often, until the pasta is tender and most of the liquid has been absorbed, about 12 minutes.
Stir in lemon zest, lemon juice, pepper and chicken. Serve topped with basil, if desired.
