Cook the pasta according to package directions in a large pot of salted boiling water.
While the pasta cooks, prepare the lemon ricotta sauce in a large mixing bowl.
Once the pasta is cooked, drain it, reserving about a cup of the pasta water.
Add the hot pasta directly to the mixing bowl with the ricotta sauce.
Toss the pasta with the sauce, adding reserved pasta water as needed for consistency.
Taste and adjust seasoning with additional salt, pepper, or lemon juice, if necessary.
Serve the lemon ricotta pasta warm, garnished with fresh herbs and extra Parmesan if desired.
