Butternut squash is something I learned to love from my grandmother Denny, who’d roast big pieces of it on a cookie sheet and then mash it with lots of butter, salt, and pepper. Of course that tasted great, but when I make Roasted Butternut Squash with Rosemary and Balsamic Vinegar, I don’t miss the butter at all. There are a lot of good butternut squash recipes on the blog, but this simple one never fails to please me.

This recipe is about as easy as they come, especially if you use those pre-cut squash cubes that start to show up at this time of year. If you’re cutting your own squash (which is the way I like to do it) you might want to read How to Peel and Cut Up a Butternut Squash before you start.

But if the only way this is going to happen at your house is using those pre-cut squash cubes that show up in the fall, go ahead and use them for this Roasted Butternut Squash with Rosemary and Balsamic Vinegar. Either way, this will be delicious!

How to Make Roasted Butternut Squash with Rosemary and Balsamic Vinegar:

(Scroll down for complete recipe with nutritional information.)

  1. I like to mix the olive oil, 1 T balsamic vinegar, and chopped rosemary to be sure it gets evenly distributed on the squash pieces.
  2. Toss the squash cubes with the mixture, turning it over several times so the squash pieces are well coated.
  3. Spread squash out in a single layer on the baking sheet and roast at 400F/200C for about 20 minutes.
  4. Then turn the squash pieces over and roast about 20 minutes more, or until squash is soft and starting to get caramelized.
  5. When it’s done, toss squash with 1-2 teaspoons more of your best balsamic vinegar, season with salt and fresh ground black pepper and serve hot.

Roasted Butternut Squash with Rosemary and Balsamic Vinegar couldn't be easier, but the results are amazing for this perfect winter side dish!

Ingredients

  • 2 lbs. butternut squash cubes (see notes)
  • 2 T extra virgin olive oil
  • 4 tsp. best quality balsamic vinegar
  • 1 tsp. very finely chopped fresh or frozen rosemary, or slightly less dried rosemary (see notes)
  • sea salt to taste
  • fresh ground black pepper to taste

Instructions

  1. Preheat oven to 400 F/200C.
  2. Mix together the olive oil, 1 T balsamic vinegar, and rosemary, then toss squash cubes with the mixture.
  3. Arrange the squash on a cookie sheet or dish large enough to hold it in a single layer.
  4. Roast 20 minutes, then turn squash and roast about 20 minutes more, or until squash is very soft and starting to get slightly caramelized.
  5. Remove from oven and toss squash with additional 1 tsp. balsamic vinegar, sea salt, and pepper. You can mash slightly if you want, but I keep mine rather chunky. Serve hot
  6. This is also excellent made ahead and reheated. For a holiday like Thanksgiving where there are lots of demands on the oven, it could be cooked early in the day and kept warm in a crockpot while other things bake.

Notes

Use about 6 cups of butternut squash cubes, or slightly more. Be sure it's especially finely chopped if you use dried rosemary. If you have a garden you can make frozen rosemary and use it in this recipe!

  2. This does look delicious, never thought I would live to say I would try squash or anything related. Thanks for a great post!

  3. This looks like such a good side dish, Kalyn! Love it!

  4. This really looks healthy as well as delicious! Can't wait to make it.

  5. Thanks Maria. I am so happy with it.

  6. I love your new site design. Love it! Great recipe too:)

  7. Dawn, that sounds good!

  8. I just made a roasted kabocha and sweet potato mixture that came out so well. I used lemon rather than the vinegar. I will have to try the balsamic next time cause I love it!

  9. Thanks Susan. I agree, that five years sure do go by quickly didn't it?

  10. The new design looks GREAT, Kalyn. This squash looks great, too – and I've been meaning to try your recipe since your first posted it! No excuse now, as I have several butternuts in the pantry (I knew I was saving them for something) and some beautiful rosemary in the greenhouse.

    Congratulations on the new look, and on all your well deserved success with Kalyn's Kitchen. I can't believe we've been blogging for over five years! xoxo

  11. Thanks for the nice feedback, both about this recipe and the new look of the blog.

    Amy I like the idea of combining butternut squash and sweet potatoes!

  12. I did something similar to this for Thanksgiving. I had a butternut squash and two sweet potatoes. I tossed the cubes in olive oil, rosemary, salt, pepper and garlic powder, then baked.

    I took some orange marmalade and melted it and then gently tossed the cubes with the marmalade.

    It was good! but next time I'm leaving off the marmalade. I liked it just roasted.

    Amy

  13. I love the new look of your blog, and this recipe sounds wonderful.

  14. I love that you left out the butter and it still tastes great. Love your new look.

  15. I am a roasted butternut squash fan Kalyn.

  16. Thanks Dara and Helen.

    As for peeling the squash, I tried the squash cubes a few times and I think the freshly peeled squash is much more flavorful! But I realize that peeling squash isn't for everyone.

  17. Love the new look! I like that you have a section that lists our previous posts. Your global readers will appreciate the recipe conversion section. Count me in as a reader who has previously tried your roasted butternut squash recipe. It was wonderful! Well worth the challenge to peel the squash.

  18. The new look of your blog is fantastic, Kalyn! This butternut squash recipe is calling my name. Rosemary and balsamic vinegar…nice.

  19. Stephanie, thanks! One of my own favorites as well.

  20. Best butternut squash recipe EVER! I have made it several times and every last bite is gone. It was a highlight at our thanksgiving this year! People were even nibbling on it cold afterward so there were no leftovers for the next day. THANK YOU!
