Butternut Squash Alfredo Sauce Recipe - garlic and Parmesan Alfredo pasta sauce made from butternut squash. No cream and gluten free, this 4-ingredient healthy version is perfect for pasta lovers!

BUTTERNUT SQUASH ALFREDO SAUCE
Remember that time, when my pasta-loving self was blown away to learn that you can make a creamy Roasted Garlic Cauliflower Alfredo sauce from a vegetable? Well, guess what! I did it again!
I made a creamy, buttery (pun intended!) Alfredo pasta sauce with butternut squash, garlic and Parmesan. It's smooth, delicious and the color just screams fall to me. This bright orange veggie pasta sauce is perfect for pasta lovers who are looking for healthier ways to enjoy their favorite food. In other words: you HAVE to try it!!
HOW TO MAKE BUTTERNUT SQUASH ALFREDO SAUCE:
I based this recipe completely on my Roasted Garlic Cauliflower Alfredo sauce.
- After peeling the squash, I cut it into small cubes and cooked in a pot with water until soft. I had 5 cups of squash.
- After cooling it, I added it to the blender along with fresh garlic cloves and Parmesan cheese and ¾ cup of water. You can use cream or milk of course, but I wanted to keep this recipe cream free and honestly, I do not find that this sauce needs to be any more creamy.
- Use vegan Parmesan cheese for a full dairy free option. This is smooth, buttery and tastes just like Alfredo sauce should: garlicky and cheesy.

I will admit, experimenting with vegetables and using them to make a pasta sauce makes me so excited. I have so much fun having my kids and my Hubby taste test it, they always think it's cool the sauce is made from a vegetable. They are already big fans of the cauliflower sauce (and so many of you are too!), I was hoping they will love this squash version as well. My kids, of course, loved that it's orange. Halloween is approaching and they are already excited. I used this sauce to make mac and cheese and they quickly called it Halloween Mac! 😀 Talk about making eating veggies fun!

Made this tonight - thought it was a bit too thick, added some vegetable stock. I love spice but would have to cut the garlic down next time if serving it to folks outside of my spice loving family. Might try the half and half option that another reviewer mentioned. Overall great idea - just picked three today and was looking for a new idea.
Susie says
If we use butternut squash that is pre-cooked and mashed , how many cups would we use? I cook butter nut squash in great quantities when I find it cheap at the market. I store it in the freezer for use in dishes.
Petunia says
I tried the recipe as directed and it was way too much garlic. I had to use half and half to balance the flavors. Having said that it came out yummy with the half and half but I know next time to use less of directed garlic.
Kim says
Can you freeze this and your roasted cauliflower sauce?
Renee says
This seems like a delicious idea, however this recipe is described as no dairy but has cheese in it. I will make this by exchanging the real Parmesan for vegan Parm. Can you please revise the description and remove the "no dairy" descriptor. It is misleading for people looking for dairy free recipes.
Fleta says
Hey! Looks delicious, just wondering, would this have the same effect if sweet potatoes were used rather than butternut squash?

Looks amazing!!
Quick question please? Do you know if this can be frozen after it's cooked? since the kids are grown and gone,, there's just two of us.
Thanks!!
Nikki says
I made this yesterday (roasted the garlic first, as in your cauliflower version of this recipe) to eat with my zoodles and it came out really good.
HOWEVER - used the leftover sauce tonight on top of my riced cauliflower and it was AMAZINGLY delicious!! Maybe it just pairs extremely well with riced cauliflower but daaaaayum was it good.
Thank you!
Anna@CrunchyCreamySweet says
