Butternut Squash Pasta Sauce

Sharing is caring!

If you’ve been around my kitchen long enough, you know that I love finding fun and delicious ways to sneak more veggies into my meals, especially when they’re wrapped up in creamy, cozy comfort like this Butternut Squash Pasta Sauce!

This recipe feels like a gourmet meal, but it’s so simple to make. It’s rich and velvety like Alfredo, but lighter and made with real ingredients you can feel good about. One of my favorite butternut squash dishes is my Whole Roasted Butternut Squash.

The natural sweetness of roasted butternut squash, blended with garlic, onions, and a splash of cream, gives you a sauce that pairs perfectly with pasta, gnocchi, or even grilled chicken.

This sauce is very creamy and goes great with any type of pasta you serve it on.

Because this sauce is so versatile, you can even use it as a pizza sauce for an upscale, delicious dinner idea.

Why You’ll Love This Butternut Squash Pasta Sauce:

  • It’s a great way to use up fall squash – but honestly, I make this year-round! Another great way to use this squash is to make Parmesan Butternut Squash Gratin.
  • Packed with flavor thanks to roasted garlic and onions.
  • Creamy and comforting without being overly heavy.
  • Kid-friendly and husband-approved – even picky eaters love it!

How to Make Butternut Squash Pasta Sauce

Peel and dice up one butternut squash. Once you peel and cut it in half, you will have to remove the seeds from it just like you do a pumpkin. I got this butternut squash from Melissa's Produce. I love that they have so many delicious veggies to choose from.

Once you get it diced, then, in a large stockpot, add in the olive oil, onions, and saute until they are soft and tender.

Add the butternut squash, garlic, herbs, and broth, then cook for 10 minutes or until the butternut squash is fork-tender.

Once the butternut squash is tender, add the milk to the pot.

Use an immersion blender to blend the sauce.

While the sauce is simmering, cook your pasta according to directions.

To serve, add some sauce to your bowl, then add some pasta to the bowl. Then, pour more sauce over the top. Gently toss to coat.

Top with Parmesan shavings and toasted pecans. The pecans I used are delicious pecans from the Millican Pecan Company.

This recipe tasted SO good. I am so glad that I ventured outside of my normal cheese sauce to create this pasta sauce. It's my new favorite, and I may never go back to regular pasta sauce again. Be sure to check out this squash dish — Ground Chicken Stuffed Delicata Squash.
