Course: Main Course
Cuisine: Italian
Servings: 4


  • 1 pound penne or rigatoni, ziti, etc.
  • 2 tablespoons unsalted butter
  • 2 tablespoons olive oil
  • 1 medium onion diced
  • 3 ounces tomato paste
  • 2 cups low sodium chicken stock
  • 5 cups butternut squash cubed
  • 1/4 cup sage chopped
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 3/4 cup Parmigiano Reggiano grated
  • 1/2 pound mozzarella cheese shredded, divided


  • Preheat oven to 400f and set rack to the middle level. Saute onion in the butter and olive oil over medium-low heat until soft (about 5 minutes).
  • Add in the tomato paste, chicken stock, butternut squash, chopped sage, salt, pepper, and cook partially covered over medium heat until the squash is fork-tender (about 20 minutes).
  • Meanwhile, cook pasta in salted water to very al dente. About 2 minutes less than the package instructions.
  • In a large bowl add half of the butternut squash sauce and the pasta. Add in the Parmigiano Reggiano cheese and 2/3's of the shredded mozzarella. Gently mix together.
  • Place a layer of butternut squash sauce into the bottom of a 9 by 13" baking dish. Add the pasta and top with the remaining sauce and the remaining shredded mozzarella.
  • Cover with parchment paper then foil and bake for 20 minutes. Remove the covering and cook for 10 more minutes. If you want the cheese browned broil for 1-2 minutes, but watch carefully to avoid burning. Let rest for 5-10 minutes before serving. Enjoy!



  • Microwaving the whole butternut squash for 3 minutes can help soften the hard skin and make peeling easier.
  • When cooking the sauce keep the lid slightly cracked to encourage a bit of evaporation and to help the hard squash soften more quickly.
  • Covering the pasta with a layer of parchment paper, then foil, prevents the cheese from sticking.  If you don't have parchment paper try wiping a bit of oil onto the foil to prevent sticking.
  • Fried sage leaves can be used as a garnish for a nice visual effect.  To cook, just fry the sage leaves for 60-90 seconds in a 1/4" layer of hot olive oil.
  • Leftovers can be saved for up to 3 days and can be reheated in the microwave until warm.
