Cook pasta according to packaging instructions. Once pasta is finished cooking, reserve ½ cup of starchy pasta water in a cup to the side before draining the pasta.

In a bowl, combine ricotta cheese, lemon juice, lemon zest, parmesan cheese, minced garlic, and salt. Stir to combine.

When pasta has been drained but is still hot, add in baby spinach and allow to wilt.

Stir in ricotta sauce mixture along with the reserved pasta water and stir to coat.
