Step 1

Bring a large pot of salted water to a boil. Add the pasta and cook as the label directs. Reserve 3/4 cup cooking water, then drain.

Step 2

Meanwhile, heat the butter and olive oil in a large skillet over medium-high heat. Add the shallot and garlic and cook, stirring, until the shallot is tender, about 3 minutes. Add the cannellini beans and olives and cook until warmed through, about 2 minutes. Season with salt and pepper.

Step 3

Remove the pan from the heat and stir in the pasta, lemon zest and juice and 1/2 cup of the reserved cooking water. Toss well, gradually adding the remaining cooking water if the pasta seems dry. Stir in 1/4 cup each Parmesan and parsley. Divide the pasta among bowls and top with the remaining Parmesan and parsley.
