Pasta is my go-to meal choice around here these days, partially because I know that my entire family will happily eat it any night of the week! I took our usual favorite, spaghetti, and gave it some fall flavors to create this butternut squash pasta. Best of all, this meal is on the table in less than half an hour, and the delightfully creamy sauce is made with just a handful of ingredients! How can you go wrong with that?

How do you make butternut squash pasta?

This recipe starts with bacon, which is cooked until crisp. Finely diced onions and garlic get cooked in a little bacon fat which forms the base of the sauce. The sauce also contains butternut squash puree, heavy cream and parmesan cheese. Spaghetti is tossed in the sauce, then the reserved bacon goes on top with a sprinkle of parsley. Serve, and enjoy!

How to make butternut squash puree

For this recipe, you can use a box of frozen winter squash puree that’s been thawed, or you can make your own butternut squash puree. You’ll want to start with a medium sized squash, around 2 pounds in size. Cut the squash in half lengthwise, then scoop out the seeds. Place the squash, cut side down, in a pan with 1 inch of water. From there, you can either microwave the squash halves, covered, for 10 minutes, or bake the squash at 350 degrees F for 45 minutes. You want the cooked squash to be quite soft. Use a spoon to scoop the cooked squash out of its skin, then place the squash in a food processor and puree until smooth.

Tips for butternut squash pasta

  • Freshly grated parmesan cheese tastes best in this recipe, and it melts smoother compared to pre-grated cheese, which often contains anti caking agents.
  • The butternut squash sauce can be made up to 2 days before you plan to eat it, it also freezes well for later use.
  • If you feel that your squash sauce is a little too thick, add some cooking water from the pasta, 1 tablespoon at a time, until the desired consistency is reached.

Pasta Variations

This pasta is delicious as-is, but you can switch up the ingredients to customize the recipe to your tastes.

  • Protein: Try topping your pasta with grilled chicken, shrimp or sliced steak.
  • Pasta: While I often use spaghetti for this dish, other options include linguine, farfalle, penne or even cheese tortellini.
  • Vegetables: You can mix some veggies into your pasta such as kale, sauteed red onions or  mushrooms.

    Perfect, I have a pumpkin sitting on the kitchen bench and was thinking what to cook with it. Problem solved!

    I made this the other night for my family and they all thought it was amazing! who knew that butternut squash and chicken were so good together!

  3. Amazing dish, the purée tasted amazing and just the right amount of sauce! Butternut squash tasted great with the chicken????❤️

  4. I just had this at a restaurant!!! They used bow tie pasta and added spinach leaves as garnish. Also, be careful about the bacon amount. We each had a heaping tablespoon of bacon on top and it was too much, way too salty. A heaping teaspoon would have been more than enough. Otherwise, a great dish.

  5. Well that’s the prettiest plate of pasta I’ve seen for ages. I could just dig my fork into it now!

  6. Such a beautiful dish! Love butternut pasta sauce and with that beautiful chicken and bacon, it’s very much a yes please!

  7. I had the best time watching your video for this recipe with my 4 1/2 year old grandson. We talked about all the ingredients as you put them in – ohhh pasta, yum bacon, etc. This looks so easy I bet he could help me make it – and it looks so good I would serve it to company. Thanks Sara!
