How to Make It
Preheat the oven to 425°. In a bowl, toss the broccoli rabe with 2 tablespoons of the oil and season with salt and pepper. Arrange the broccoli rabe on 2 baking sheets and roast for 15 minutes, until crisp-tender, then chop.
In a deep skillet, heat the remaining 2 tablespoons of oil. Add the garlic, chile and harissa and cook over moderate heat, stirring for 2 minutes. Add the broccoli rabe and smoked paprika and cook until tender, 2 minutes.
Meanwhile, in a large pot of salted boiling water, cook the pasta until al dente; drain, reserving 1 cup of the cooking liquid. Add the pasta, cooking water and 1/4 cup of Parmigiano to the skillet and cook, stirring, until the pasta is coated in a thick sauce, 2 minutes. Stir in the herbs and serve with more cheese.
