Step 1

Mix the ricotta with a blender (or by hand with a whisk), with 2 tablespoons of olive oil, vinegar, salt, and pepper, until you get a yogurt-like consistency. If it is not soft enough, mix in 1 to 2 tablespoons of warm water.

Step 2

In a large bowl, stir the spinach into the ricotta mixture and set it aside.

Step 3

In a large pot of salted water, cook pasta according to package directions for al dente pasta. Scoop some pasta cooking water out of the pot with a heatproof measuring cup, then drain the pasta. Combine the pasta with the ricotta and spinach mixture in the bowl.

Step 4

Stir in the parmesan cheese, adding some of the reserved pasta water, if needed, to smoothly mix the parmesan with the pasta and ricotta.

Step 5

Divide the pasta into two serving dishes, top each with a tablespoon of ricotta and some freshly ground black pepper, and serve.
