Cook the pasta according to package instructions in salted water.
While the pasta cooks, prepare the sauce by combining ricotta, lemon zest, and lemon juice in a bowl.
Once the pasta is done, reserve some pasta water and drain the rest.
Combine the drained pasta with the ricotta mixture in a large bowl.
Add olive oil, arugula, and Parmesan cheese, stirring gently.
Adjust the consistency with reserved pasta water as necessary.
Taste for seasoning, adding salt and pepper as needed.
Serve immediately, garnished with additional Parmesan and a drizzle of olive oil.
