Method
Prepare the Cime di Rapa:
Bring a large pot of salted water to a boil. Add the cime di rapa and blanch for about 2-3 minutes until tender but still bright green. Using a slotted spoon, transfer them to a colander and set aside. Reserve the blanching water for cooking the pasta.
Cook the Pasta:
In the same pot of boiling water, add the pasta and cook according to package instructions until al dente. Reserve about 1 cup of the pasta cooking water, then drain the pasta.
Sauté the Aromatics:
In a large skillet over medium heat, add the olive oil. Once heated, add the minced garlic and red pepper flakes. Sauté for about 1 minute until the garlic is fragrant but not browned.
Combine Ingredients:
Add the blanched cime di rapa to the skillet, stirring to combine. If using anchovies, add them now and cook until they dissolve into the oil. Season with salt and pepper to taste.
Finish the Pasta:
Add the cooked pasta to the skillet, tossing to combine. If the mixture seems dry, gradually add reserved pasta water, a little at a time, until you reach your desired consistency.
Serve:
Plate the pasta and finish with a sprinkle of lemon zest and grated Parmigiano-Reggiano cheese. Enjoy while hot!
