A quick and savory one-pan pasta dish perfect for the fall season. This recipe features penne pasta tossed with crispy diced pancetta and tender, shredded butternut squash. The flavor base is built by cooking the pancetta with garlic and red pepper flakes. The shredded squash is then quickly cooked in the same pan. A simple sauce is created by tossing the cooked pasta with the squash and pancetta, along with a splash of the starchy pasta water, and is finished with grated Parmesan cheese.
