Pasta and Butternut Squash Casserole Recipe


  • 12 oz Ronzoni Smart Taste Pasta, or any whole wheat, high fiber pasta
  • 20 oz butternut squash, fresh, peeled and cut into bite sized pieces
  • 1 1/4 cups fat-free skim milk
  • 2 tbsp whole wheat, all-purpose flour
  • 4 garlic cloves, minced
  • 1 tbsp light butter
  • 1 tbsp fresh thyme, finely chopped
  • 1 tbsp fresh sage, finely chopped
  • 1 tsp Kosher salt
  • ¼ tsp black pepper
  • 1/2 cup part-skim ricotta cheese
  • 1/3 cup grated Parmesan cheese


  1. Preheat oven to 375ºF. Coat a baking sheet with cooking spray. Coat a 2 ½ quart baking dish with non stick cooking spray (preferably the butter flavored kind).
  2. Place squash on prepared baking sheet and sprinkle with a bit of salt; roast until tender, about 20 to 30 minutes. Place in a large bowl.
  3. In the meantime, cook pasta according to package directions; drain and return to pot.
  4. In a medium saucepan, whisk together milk, flour, butter, garlic, salt and pepper.
  5. Bring to a boil over medium-high heat, whisking frequently; reduce heat to low and simmer, stirring often, until thickened, about 2 minutes.
  6. Remove from heat; stir in squash, thyme and sage. Add sauce to pasta; toss to mix and coat.
  7. Transfer pasta mixture to prepared baking dish; dollop with spoonfuls of ricotta and then sprinkle with Parmesan cheese.
  8. Bake until top is lightly browned in a few spots, about 15 to 20 minutes.

  1. Does anyone know the POINTSPLUS value of this recipe?

  2. I made this tonight and it was a hit with everyone. I added red kidney beans and broccoli to the pasta, and subbed EVOO for the butter. Thanks for the wonderful recipe!

  3. I made this casserole tonight and it was wonderful. I did not have any thyme so I used some parsley and it was still great. Thanks for sharing

  4. I definitely want to try this recipe, but I was wondering if you have any recommendations on something I could substitute for the ricotta? (I'm not a big ricotta fan :) )

    • You could use fat free cottage cheese instead…though try to mash it up a lot first.
