In a large pot, bring water to a rapid boil and add a generous amount of salt. Add the pasta of your choice and cook according to package instructions until al dente. Reserve 1 cup of pasta water, then drain the rest.

In the same pot, heat the olive oil over medium heat. Add the minced garlic and sauté for about 30 seconds until fragrant. Then, toss in the fresh spinach and a pinch of salt, cooking until wilted (about 2-3 minutes).

Lower the heat and stir in the ricotta cheese, lemon zest, lemon juice, and a little bit of the reserved pasta water. Stir until everything is well combined and creamy, adding more pasta water as needed to achieve your desired consistency.

Add the drained pasta to the skillet and toss to coat everything in the creamy sauce. Adjust seasoning with salt and pepper to taste.

Plate the pasta and sprinkle with freshly grated Parmesan cheese if you desire. Enjoy this delightful dish immediately!
