03Bring a large pot of salted water to a boil. Cook the penne 2 minutes less than the package directions. Meanwhile, rewarm the sauce in a large, straight-sided skillet set over medium heat. Using a spider, strain the pasta from the water and add it directly into the pan with sauce, reserving 1/2 cup of the pasta water. Before stirring, sprinkle the pasta with the grated cheese. Toss the pasta, cheese and sauce together. Add the butter, the remaining 2 tablespoons olive oil and the reserved pasta water and continue to cook until the sauce is creamy and the pasta is al dente. Serve topped with more cheese if desired.
