It’s so easy to get into ruts when it comes to meals. I’ve found that meals are a lot more exciting, however, if I simply change up the side dishes.

Mashed potatoes and mashed sweet potatoes are tried and true family favorites, but over the years I’ve had a lot of fun experimenting with a wide variety of veggies to replace the potatoes.

My parsnip purée and mashed cauliflower recipes are lower carb and so delicious that I never get any complaints!

This Mashed Butternut Squash is my latest creation, and this dish has added plenty of pizzaz to our dinner table.

The color alone is enough to make me happy, but the velvety texture and sweet, savory flavor is why I’ve been making this recipe time and time again lately.

I have no idea why it took me so long to try mashing butternut squash because I’ve loved the velvety texture of my butternut squash soup for so long.

Thankfully when I was developing my post how to cut butternut squash, I made a purée out of my cubed squash and knew I had a new side dish!

There’s no going back now. 🙂

Ingredient notes

  • Butternut squash. This recipe takes 5 cups of cubed butternut squash, or a 2 1/2 lb. whole squash. You can opt to purchase prepped squash, but it’s much more cost effective to do it yourself. You can boil cubed butternut squash or roast a whole squash for this recipe. See the recipe card below for more information.
  • Garlic. Butternut squash is nice and sweet on its own, so I added fresh garlic cloves to the squash to make it nice and savory. The garlic is boiled along with the butternut, so the flavor is much more mellow. It can be omitted to make this recipe low FODMAP.
  • Butter and olive oil. A bit of butter and olive oil adds nice buttery flavor and makes the texture of the mashed butternut nice and silky. I’ve prepared it with milk or cream, but I prefer this dish without the added richness. This is a personal preference, and you can certainly replace the olive oil with milk or cream. Make this recipe dairy-free by subbing the butter dairy-free butter or coconut milk.
  • Chives. The chives are completely optional, but I highly recommend adding them as they add freshness and mild onion flavor. They may be subbed with chopped parsley or your favorite fresh or dried herbs.

FAQs

Is it better to boil or roast butternut squash?

Either method works great in this mashed butternut squash recipe…it’s really personal preference.

Boiled butternut squash requires peeling and cutting the squash into about 1 1/2″ sized cubes. You can also purchase pre-cut squash as a time saver.

I don’t recommend roasting cubed squash for this recipe as it dries out in the oven, so if you prefer to roast it, follow the instructions in my roasted whole butternut squash recipe which is linked in the recipe card below.

What brings out the flavor of butternut squash?

Butternut squash has an amazing sweet, nutty flavor that pairs well with both sweet and savory ingredients.

This savory mashed butternut squash includes garlic, butter and freshly chopped chives. Fresh herbs and savory spices are also great additions.

If you prefer a sweeter side dish, consider adding maple syrup or honey, ground cinnamon or orange zest for added flavor.
