Rosemary Balsamic Butternut Squash is one of my favorite fall side dishes.

Rosemary Balsamic Butternut Squash | stephgaudreau.comWhat’s not to love about caramelized roasted butternut – one of my favorite fall veggies – drizzled with an infused rosemary balsamic glaze…and only 4 ingredients? Sounds like a mouthful of autumn awesome to me.

How I Make This Rosemary Balsamic Butternut Squash

The first time I had squash like this, it was grilled (outdoor cooking for the win), but with the weather turning cooler (and with a lack of a grill here in Scotland) I decided to bake it in the oven. It was every bit as tasty.

If you want to save time, you can leave the butter squash unpeeled. Yes, the cooked skin softens and is edible. For maximum flavor, use fresh rosemary if you can.

What Can You Use Instead of Butternut Squash?

You could use another hard squash like kabocha or acorn!

Rosemary Balsamic Butternut Squash is one of my favorite fall side dishes. The sweet-tangy balsamic goes perfectly with the fresh rosemary.



  • 1 large butternut squash peeled
  • 1 tbsp melted coconut oil or avocado oil
  • 1 tbsp chopped fresh rosemary
  • 1/3 cup balsamic vinegar
  • 2 sprigs fresh rosemary
  • sea salt to taste


  1. Preheat your oven to 400°F. Line two baking sheets with parchment paper.

  2. Peel the squash, if desired. Cut it lengthwise down the middle. Scoop out the seeds (they’re great toasted). Lay the halves flat and cut them into thin half circles (no larger than ¼” thick).
  3. Put half the squash on a baking sheet. Drizzle with half the oil / fat. Sprinkle with half the rosemary and a pinch of salt. Toss everything until the squash is well coated. Repeat with the other half of the squash.
  4. Bake the squash for about 20 minutes or until the edges are browned. Check once during baking, flip the pieces over, and return to the oven.
  5. While the squash is baking, make the balsamic vinegar reduction. Pour the vinegar into a small pot, and add the rosemary sprigs. Bring to a boil then turn the heat down medium-low. You want to reduce this by at least half so the vinegar thickens enough to coat the back of a spoon but not so much that it completely sticks to the bottom of the pan (or even worse, starts to burn. Try not to walk away from the stove while you’re doing this…I know from experience). Once the vinegar is reduced, discard the rosemary sprigs.
  6. After the squash is roasted, serve by drizzling with the balsamic vinegar reduction. A little goes a long way.

  1. Well. Thank you for finding a way for me to eat my squash and love it too. I used to dislike the orange squash as a child because it had no flavor. Always had it for thanksgiving and was not happy it was on my plate. Now. Looking forward to enjoying this vegetable with that great good balsamic vinegar. My squash. Will never be the same . I’ll buy it now

    1. Hi Cheryl…knowing that I helped someone like a vegetable again is a pretty huge compliment. I thank you for writing in to let me know! (No offense to my mom if she reads this, but she always made really bland steamed veggies!!). It wasn’t until much later in life that I tried some of the veggies again that I swore I’d never eat. Happy eating!

  2. I finally made this tonight after drooling after it since you posted it. Cutting all those things slices was a bit of work but good thing I softened the squash in the microwave for 3 minutes first. So yummy and I felt like such a chef cooking with fresh rosemary and making the sauce, which was super easy, by the way. My culinary skills got bumped up a knotch tonight! Thanks!

  3. Sounds really good with the Rosemary.
    Another wonderful squash to consider is Delicata. It has a very smooth texture and is much easier to slice than butternut. The skin is entirely edible (believe me, I had my doubts).
    For extra flavor add some red/ purple onion while roasting. Mmmm mmm good!

  4. I just finished cutting the squash. Is it possible to use the precut chunks of squash I see in the grocery store? It was really hard to cut.

    1. Hi Susan,

      You could always roast the squash a bit first so it’s easier to slice into. If you find fresh pre-cut squash, I’d say go for it.

  5. It is a snow day staying home….
    I do not have fresh rosemary can I substitute with dried rosemary if so how much?
