Creamy, dreamy deliciousness, this mashed butternut squash and sweet potato recipe is easy to prepare, feeds a crowd and is so incredibly tasty! These squash mashed potatoes are sure to be a fall favourite!
With fall just around the corner, that means all kinds of comfort food and special meals, especially those involving winter squash.
I don’t know about you, but often I’m more excited about the side dishes than I am about the main dish.
Garlicky mashed potatoes, green beans, roasted veggies, they all make my belly happy, just like this mashed butternut squash and sweet potato recipe.
I just love this combo! And if you do too, you’ll likely enjoy this butternut squash sweet potato soup.
Fun fact: even though butternut squash is savoury (and most often used in those types of dishes), it’s technically considered a fruit, not a vegetable? Neat huh?

- 2 pounds sweet potatoes
- ½ tablespoon olive oil
- 1 teaspoon salt (plus a pinch for roasting butternut squash)
- ½ teaspoon black pepper (plus a pinch for roasting butternut squash

- Cook for 45 minutes to 1 hour or so or until both butternut squash and sweet potatoes are tender all the way through when pierced with a knife. Note: If the butternut squash, for example, is cooked before the sweet potatoes, you can remove and continue cooking the sweet potatoes.
- Once everything is cooked, carefully remove from the oven and allow to cool until you can handle it.
- Once everything is cool enough to handle, scoop out flesh from the butternut squash. Cut potatoes in half and scoop out flesh. Place into a large bowl. Roughly mash.
- Melt butter in a saucepan on the stovetop or in a microwave-safe dish in the microwave until just melted and warmed through. Add salt, pepper and pumpkin spice, stirring to combine.

Butternut squash is a fruit? Well count that as something new I learned today! We’ve made mashed sweet potatoes before, and they’re always quite tasty…but adding the butternut squash in there is a fun twist. Perfect for these early Autumn evenings!
