Boil a large pot of salted water and cook the pasta according to package directions until al dente.

In a skillet, heat olive oil over medium heat and sauté garlic until fragrant.

Add spinach and cook until wilted, then stir in ricotta cheese and parmesan until well combined.

Add lemon juice, toasted pine nuts, salt, and pepper, and stir to combine.

Drain the pasta and reserve some pasta water. Combine pasta with the spinach mix, adding reserved water as needed for creaminess.

Serve immediately, garnished with additional pine nuts and parmesan if desired.
