Easy Roasted Buttercup Squash with Balsamic Glaze

I still have a couple more recipes to add to the collection of Carb Conscious Thanksgiving Recipes I’ve been working on for the last few weeks, but somehow this recipe for Easy Roasted Buttercup Squash with Balsamic Glaze just went right to the front of the line. This idea was in my head for about a week, and today I finally got around to cooking it.

This squash was beyond delicious, one of those dishes where I find myself eating it as soon as the photos are shot. It’s also one of those easy Five Ingredients recipes so many people are fond of. If you can add just one more Thanksgiving side dish to your table, this is the one!

Easy Roasted Buttercup Squash with Balsamic Glaze

You could make this with any type of winter squash, but I’ve been wanting to try some new types and I loved the buttercup squash I used here. I forgot to take a photo before I cut it up, but you can see it in this squash glossary if you’re curious. I actually cut this squash and left it in the fridge in a Ziploc bag for five days before I finally cooked it, so you can definitely cut it ahead of time. The combination of Balsamic Vinegar with just a little Agave Nectar (or another sweetener) brushed on the squash was so perfect! I had a lot of this glaze left over, so in the recipe I reduced the amount from what is shown here.

First I brushed the squash with the glaze and roasted at 400F for 15 minutes. Don’t worry if the glaze runs down to the bottom of the pan, because it will coat the bottom side of the squash in a most delightful way. Then I turned the squash over, brushed lightly a second time and roasted for 15 minutes more on the second side. Thirty minutes was perfect for these pieces of squash, but you might need a bit longer if your squash pieces are thicker. Grind over some sea salt and black pepper and eat!

Easy Roasted Buttercup Squash with Balsamic Glaze

Easy Roasted Buttercup Squash with Balsamic Glaze is a delicious change from the usual brown-sugar loaded winter squash you see this time of year.


  • 1 buttercup squash, or other winter squash (about 1.5 lbs.)
  • 1-2 T Agave Nectar (use another lower-glycemic or low-carb sweetener if you prefer but the stickiness of the agave gave good results here)
  • 2 T good quality balsamic vinegar (I used Fini Balsamic Vinegar)
  • freshly ground black pepper and sea salt to taste


  1. Cut top and bottom end from squash, then sit flat on cutting board and cut in half top to bottom. Use a sharp spoon to scrape out seeds, washing out the inside of the squash if needed.
  2. Cut squash into half-moon slices about 1 inch wide. (Any shape of slice will work, but they need to be close to the same thickness.
  3. Preheat oven or toaster oven to 400F. Spray roasting pan with non-stick spray or olive oil. I was using a toaster oven, so I used a 13″ X 9″ roasting pan.)
  4. Lay squash in single layer on roasting pan. Mix together agave nectar and balsamic vinegar (I used Fini Balsamic Vinegar) and brush on top layer of squash. (Some will run down, which will coat the bottom as the squash roasts.)
  5. Roast squash 15 minutes, then turn each piece. Brush second side lightly with the agave-balsamic mixture. (It will look glazed already and you may be tempted not to brush it, but do it so the glaze can run down and coat the other side.)
  6. Roast 15 minutes more, or until squash pierces easily with a fork and is lightly browned.
  7. Grind black pepper and sea salt over squash and serve hot. (You could make this easier to eat by cutting off the peeling before eating, but I thought it was simple enough to cut the rind off as you ate it, and I kind of liked the look of the squash with the rind left on.)

Low-Carb Diet / Low Glycemic Diet / South Beach Diet Suggestions:
The South Beach Diet cookbooks list butternut squash as phase two, so this Easy Roasted Buttercup Squash with Balsamic Glaze is probably phase two for a small serving or phase three if you have a lot. This is too high on carbs for a traditional low-carb eating plan.

  2. I just had to tell you that this recipe is heavenly ! This is the first time I have ever had buttercup squash, but it will not be my last-it really is like a dense sweet potato. In fact, I like it better than sweet potatoes.
    I had some maple-flavored agave nectar on hand and used that in this recipe-incredible ! Thanks for the marvelous recipe.

  3. I only use agave to sweeten my tea, I’ve really got to try it in my cooking!

  4. Kalyn this sounds great! Now that I know what buttecup squash is :o)

    The other night I had a margarita sweetened with agave nectar. It made me want to buy some to use in cooking!

  5. simple and so delicious!!

  6. That looks delicious. I love squash. The latest version we had was roasted with a liberal sprinkling of smoked paprika! Addictive!

  7. Wow, two of my favorites together at last: Squash and Balsamic Vinegar. Awesome idea, Thanks a million for it. 🙂

  8. So glad everyone is liking this. One of the best things I’ve cooked for a long time!

    CC, please do come for the party. Wouldn’t that be fun!

  9. Stunning! Party at Kalyn’s house; I’ll be there too.
    That looks beautiful and so easy.

  10. Yum, I keep looking for good recipes to use my Agave. Squash sounds so yummy right now (it’s finally gotten cold here and, gasp, may even rain!)

  11. Brilliant! And so easy, I am jazzed. We are just covering SQUASH in culinary class, so it was nice timing to run across this recipe.

    Happy Thanksgiving Kalyn!

  12. You are always cooking up amazing dishes! Love this one!!

  13. RG, I think agave will stay good pretty much indefinitely. I know I had some for over a year and it was still fine.

    Ilva, come on over too. Wouldn’t that be wonderful!

    Sue Bette, yes this was definitely inspired by those maple syrup glazed squashes that are so yummy!

    Dayna, hope you try it. Do try the buttercup squash too if you can find it. I loved it!

    Jesse, thanks. I don’t know what made me think of the combination (certainly I am not brilliant!) but it was really a winner. I’m thinking this will taste great brushed on roasted salmon or other veggies too.

  14. Agave nectar is a gift from god, I swear. I love that stuff! Never thought of pairing it with balsamic vinegar before though… you’re brilliant!

  15. This looks as great as it sounded!
    Squash is one of my favorite things, so this is certainly something for me to try.

  16. The glaze looks amazing – when I am roasting fall veg. I usually reach for the maple syrup – totally out of habit (esp. when living in Vermont) – but I can see how the agave would add some really nice citrus notes.

  17. I really like the balsamic vinegar-squash combination! I’m coming along with Karina!

  18. I’ve had agave nectar in my pantry for months now. Hope it’s still good to use!! I just picked up some acorn squash today. Looks like I have all I need to make this. It looks terrific.

  19. Karina, ANY TIME! You just drive on up here. We will have so much fun!

  20. Kalyn, may I come to your house and stay for awhile? Lipsmacking!
