The recipe is based on what my friend Chrissie told me she made for dinner the other night. It’s one of my new favorite things.

“Kabocha Squash roasted with mushrooms, leeks and tossed with olive oil, vinegar and sea salt = WIN!”

I didn’t have kabocha squash in the house, but we are rich with butternut squash! The only ways I’ve ever made butternut squash are stuffed or in soup, so I was excited to try out a new recipe!

I served this topped with a diced, pan fried Field Roast veggie sausage, and it was pretty much the perfect fall meal! Since the sausage was super flavorful, I opted to skip tossing it in the dressing that Chrissie talked about, but I can’t wait to eat the leftovers that way!

Roasted Butternut Squash Recipe with Mushrooms and Scallions


  • 1 butternut squash, cubed with seeds removed
  • 6 large scallions, diced (Leeks would be stellar, too! Since the CSA basket had scallions, though, I went with those.)
  • 8 oz. mushrooms, cut into large chunks
  • 2 tablespoons olive oil
  • salt and pepper, to taste


  1. Preheat the oven to 425 F.
  2. Toss the veggies with the olive oil in a large baking dish. Roast for one hour, until the squash is soft, tossing every 20 minutes to make sure everything cooks evenly.
  3. Season with salt and pepper, and serve.

  2. Thanks! It was even tastier when I reheated the leftovers for lunch topped with a little Daiya cheddar!

    Oh, that steel cut oats fiasco! I’d forgotten about that! You reminded me of another rice cooker experiment I’ve been meaning to try. Maybe over the holiday there will be some time. :)

  3. The picture posted is wonderful! It looks so earthy, I may have to make this as a side dish for Thanksgiving. I read your other blog about the steel cut You had me laughing a bit “The short answer: No. No it did not.” It was just cute and it sounds like something that I may have done. ;) Thanks for sharing!

  4. I made this today; unfortunately I nearly burned everything because I forgot to toss every 20 minutes! My fault, entirely!
    We’ll eat what’s salvagable anyway this evening over some rice and expect it to be good.

    I liked the idea, because it’s something out of the ordinary.
