Twice-baked Carnival Squash with Shallots & Parmesan

If you haven’t heard of carnival squash, you’re probably not alone! We hadn’t either until we saw in in the market a couple of weeks ago. It’s so pretty and fun and colorful. But what is it? Well, it’s a relative newcomer in the squash world, developed in 1991. Although not as commonly seen in the markets as it’s cousins: acorn, Delicata, butternut, or other more familiar squashes, it sure is fun and festive and tastes delicious! In fact, carnival squash is a cross between the acorn and sweet dumpling squash varieties. All of these types of squash are considered winter squash. What we love about winter squash, besides its amazing flavor, is the fact that it is low in calories and high in nutritional value, so you get plenty of vitamins A and C and a host of other “good for you” benefits.

This recipe can be made just as easily with acorn squash as carnival squash and we really love both. The carnival meat is a little bit more dense and seems to take a bit longer to cook, but both are really delicious!

To make it even easier, we like to roast our shallots in the same dish as the squash, so they take on that beautiful roasted flavor. The shallots will cook much faster than the squash, so take them out and set them aside after about 25 minutes. The squash will take about 40-50 minutes to get to knife-tender. Then, just toss the roasted shallots into the cavity of the cooked squash, sprinkle with grated Parmesan and roast for another 15-20 minutes, or until the cheese is melted and golden brown.

Twice-baked Carnival Squash with Shallots & Parmesan

Prep Time 10 minutes
Cook Time 40 minutes


  • grapefruit spoon for cleaning out the seeds and strings
  • 9×13 making dish


  • 2 large carnival (or acorn) squash
  • 1/2 tsp. salt
  • 1/2 tsp. pepper
  • 1/2 tsp. lemon pepper
  • 2 large shallots (or 4 small) cut into eighths, lengthwise
  • 2 tbsp. extra-virgin olive oil
  • 1/2 cup freshly grated Parmesan


  • Preheat oven to 375 F. Spray a 9×13 baking dish with cooking spray.
  • Cut squash in half from top to bottom, so each half is more or less a heart shape. Remove seeds and any stringy pulp and season the cavities with salt, pepper and lemon pepper.

  • Place squash, cut side down, into the prepared baking dish. Toss the shallots in the olive oil and spread out in the dish next to the squash. 
  • Roast squash for anywhere from 25-45 minutes, depending upon the thickness. Ours took the full 45 minutes for the carnival squash, but normally acorn squash takes about 25 minutes. The shallots will be ready sooner, so check on them at about the 25 minute mark. They should be nice and browned. Remove shallots and set aside while the squash finishes baking. 
  • When the squash is tender when a knife is inserted in the center, it is done.  Remove the squash from the oven and invert so that the cavity side is now up. You can prepare the squash to this point several hours ahead of time, or even a day or two.  If you prefer, you can also cut each squash half in half again, so each squash yields four smaller pieces. Only do this after it is roasted.

  • When ready to serve, arrange the shallots in the bottom of the cavity and sprinkle Parmesan cheese evenly into the center of the squash and also on the top of the sides. Bake at 375 F for another 10-15 minutes, or until the squash is hot and the cheese is turning golden brown. Serve hot.

  1. Yum yum yum! I adore these beautiful squashes, but I’ve never tried this twice-baked approach. Thanks for the great idea!

    1. You are so welcome! It doubles the fun! Squash is so good just baked, but then adding the shallots and parmi takes it to a whole new level:)

  2. 5 stars
    I’m so obsessed with shallots right now so I know I’d love this. Plus carnival squash is an underrated squash and I need to get my hands on some before it’s too late!

    1. Thank you, Anisha! Yes, you should be able to find carnival squash now. They are usually available from early fall through winter! Hopefully, you will find some soon!
