Sweet or Savory Mashed Butternut Squash?

Many of recipes you’ll find for butternut squash are sweet. They use maple syrup or brown sugar, and often, cinnamon, nutmeg and ginger. And those sweet butternut recipe variations are totally delicious in every way. However, if you want to make a savoury version for your Thanksgiving table, then this mashed roasted garlic butternut squash is perfect.

The Easiest Way to Prepare Butternut Squash

Roasting any vegetable brings out an elevated depth of flavour. Many recipes tell you to peel and cube the squash before roasting.

Peeling and cutting a raw squash can really be a pain, (in every way, because it can be dangerous if you aren’t careful). It’s a lot of work, and effort, so why do it? Instead, just pierce the squash in a few places, then put the whole squash in the oven and let it bake. When it’s finished roasting, it will be very easy to slice, remove the seeds, and scoop the flesh off of the skin.

It does take a little longer to roast the squash whole, but you’re saving time by skipping the peeling & chopping.

  1. What a wonderful looking soup! I agree, roasting any vegetable brings about so much flavor.
    Thanks so much for sharing Colleen, can’t wait to try this.

  2. A healthy side dish for fall and winter meals! Butternut squash is my favourite, and like, you, I like savoury squash recipes instead of sweet. Pinned!

  3. This sounds like a great alternative to the usual mashed potatoes! I mean, there are only so many ways I can eat potatoes before I’m completely sick of them, especially over the fall and winter when there are fewer seasonally-appropriate options. The fried sage garnish sounds like a wonderful finishing touch, too.

  4. I appreciate a savoury recipe for butternut squash, and I love the garlic in here! I’m all for roasting the squash in the oven, too. I did a pumpkin last night.

  5. This looks really yummy. Thanks for the tip on roasting the squash whole so it’s easier to peel after…sounds much better than risking cutting off a finger when trying to peel it raw!

  6. Like you, we like to roast our squashes whole and then use the beautiful pulp. Mashed butternut squash sounds so flavorful, and very nutritious. Will make sure to add it to our side dishes of choice.

  7. I love butternut squash!! Mashed would be delightful. I usually just serve it in roasted chunks, but this would be so fantastic too!!

  8. I am a huge fan of saving time peeling and chopping so wouldn’t mind the extra time in roasted the squash whole. What a great recipe for this time of year!

  9. You know, I’m so often busy trying to think of things to turn squash into, I kind of forget to just eat it as-is! Wonderful, easy recipe, with great flavours to really make the squash pop. Cheers!

  10. I love savoury squash recipes and there aren’t enough of them! This is one that’s on my hit list for sure now – yummy!

  11. The butternut squash looks so creamy and delicious and the fried sage just takes everything to a whole new level. Bookmarked for later!
