Step 1

Cook pasta according to package directions in a large pot of boiling salted water. Scoop out a cup of pasta water before you drain it.

Step 2

While the pasta is cooking, heat the olive oil and garlic in a heavy deep skillet over medium high heat. Stir in spinach and lemon zest and toss until the spinach is wilted, about 2-3 minutes.

Step 3

Add pasta to the skillet along with the lemon juice and toss. Add in the ½ cup of Parmesan cheese and enough of the reserved pasta water to make a light sauce.  Toss until everything is well combined, drizzling in more pasta water as needed.  Season to taste with salt and pepper.

Step 4

Divide pasta among warmed bowls, garnishing with more Parmesan and a grinding of pepper, and serve at once.
