Roasted Butternut Squash & Brussels Sprouts

Slightly sweet butternut squash is the perfect pairing for earthy brussels sprouts, making it the ultimate fall side dish.

Last week, I wrote about my relationship with butternut squash – the high maintenance, tough skinned veggie that I wasn’t eager to get involved with but now finds its way into my shopping cart every fall and winter.

Once I figured out the secret to prepping butternut squash with ease, I began experimenting with recipes that only made me even more fond of it, like this week’s recipe.

Since we’ve spotlighted brussels sprouts before and now butternut squash in our Ingredient Spotlight series, it only made sense that we featured these two powerhouse ingredients together. I love roasted brussels sprouts, and the slight sweetness of butternut squash is a perfect pairing for our earthy sprouts.

If you’ve done your prep earlier in the week of the vegetables, this can be made into a quick easy weeknight side dish to a protein (such as seared and roasted pork chops or chicken breast). Tossed with a grain and a dressing, it can easily become a hearty and nutritious entree.

Prepping Smarts

  • Chop your veggies ahead of time, so when it comes time to cook, all you have to do is toss on a sheet pan and into the oven! Watch how to prep butternut squash and chop onions with our videos below.
  • If prepping ahead of time, place all chopped veggies into airtight containers / bags. Since they’ll just be tossed together, they can all be placed into one container instead of separate ones.

There's no need to wrestle with butternut squash anymore once you see how easy it is to prep this vegetable.

Equipment Smarts

  • Sheet pan – its wide surface area allows the veggies to be spread out more, caramelizing and roasting all the pieces instead of steaming them
