Step 1

Bring a large pot of heavily salted water to a boil. Add fusilli and cook until it is just shy of al dente. (It should be slightly underdone to your taste because you’ll finish cooking it in the sauce.) Drain well.

Step 2

While the pasta is cooking, prepare the chickpea sauce: Place chickpeas in a large bowl and use a potato masher or a fork to lightly mash them; they should be about half-crushed.

Step 3

Heat oil in a 12-inch skillet over medium heat. Add garlic cloves and fry until they are golden brown, about 2 minutes. Stir in onions, rosemary, red pepper flakes and a pinch of salt. Cook, stirring occasionally, until onions are soft, about 10 minutes. Then stir in chickpeas and the cooking liquid, stock or water. Bring to a simmer and cook gently until most of the liquid has evaporated, about 5 minutes.

Step 4

Stir in pasta and parsley, and cook until the pasta has finished cooking and is coated in the sauce, 1 to 2 minutes. Quickly toss in cheese, butter, lemon zest, black pepper to taste and salt if needed. Drizzle with olive oil and shower with additional cheese before serving.
