I already have a butternut squash lasagna recipe on here, and one day, one of my favorite bloggers posted a dish like this, saying it was a play on her butternut squash lasagna recipe... why didn't I think of that? This is a quicker, easier version of my butternut squash lasagna recipe. So much easier than making a whole big lasagna and just as good. If not better, just because it's quicker! This freezes very well. Pumpkin can be substituted for the butternut squash.

Blue Ribbon Recipe

Sneak veggies into dinner with this butternut squash baked penne. It's a rich and cheesy pasta dinner. The sauce is thick, creamy, and full of flavor from the Fontina and Parmesan cheeses. Mashed butternut squash adds a bit of flavor, but it's not overpowering. No one would even know it was there. We opted to add the bacon, but if you leave it off, it's a delicious vegetarian dinner. We enjoyed this vegetable mac and cheese. It will be a great addition to your fall meals.

How To Make butternut squash baked penne

Test Kitchen Tips
We steamed 2 10-oz bags of frozen butternut squash and mashed it. It was the perfect amount.
  • Drain boiled pasta.
    Step 1
    Prepare the pasta according to package directions. Drain and set aside.
  • Add onions to melted butter and cook.
    Step 2
    Preheat the oven to 350 degrees F. While the pasta is cooking, heat a large saucepan over medium heat and add butter. When melted, add onions. Whisk occasionally until the butter browns and small brown bits appear in the pan.
  • Whisk in flour, salt, and pepper.
    Step 3
    Immediately whisk in flour, salt, pepper, and cook 1-2 minutes.
  • Whisk in warmed milk.
    Step 4
    Whisk in warmed milk. When the flour mixture has been incorporated into the milk, continue to cook and stir until it starts to boil.
  • Add sage and nutmeg.
    Step 5
    Cook until thickened. Add the rubbed sage and nutmeg.
  • Blend in ricotta or cottage cheese and squash.
    Step 6
    Blend in cottage cheese (or ricotta) and mashed squash.
  • Stir in cheese.
    Step 7
    Add 1 cup of Fontina cheese and 1/2 cup of Parmesan cheese. Stir until melted. At this point, taste to see if more seasoning is needed. I tend to add more salt.
  • Stir in cooked pasta.
    Step 8
    Stir in the cooked pasta.
  • Add mixture to a baking dish and top with cheese.
    Step 9
    Spray a large casserole dish or 9x13 pan. Add pasta mixture. Top with the remaining 1 cup of Fontina cheese and 1/4 cup of Parmesan cheese.
  • Sprinkle chopped bacon.
    Step 10
    Sprinkle chopped bacon, if desired.
  • Bake until cheese is melted.
    Step 11
    Bake at 350 degrees for 20 - 25 minutes or until the cheese is golden and bubbly.
