Penne with Butternut Squash
This dish is a minimalist’s take on the northern Italian autumn staple of tortelli filled with zucca, a pumpkinlike vegetable whose flesh, like that of butternut or acorn squash, is dense, orange, and somewhat sweet. The flavor and essential nature of that dish can be captured in a thirty-minute preparation that turns the classic inside out, using the squash as a sauce and sparing you the hours it would take to stuff the tortelli.
