Meet your holiday table’s new best friend.

I can give you a beautiful story about how my family has bonded over sweet potato/marshmallow concoctions at our festivities since just about forever, but I don’t think I can do this dish justice. Just believe me when I say it’s magical.

Butternut squash is the sweet potato’s cooler yet terribly underrated cousin, and it’s about time we showed it some love. It’s creamy, flavorful, and has a fraction of the calories and carbs of sweet potato.

Pureed with the perfect blend of spices and served with a generous helping of toasted marshmallows, this underrated beauty is about to be the star in a dish you won’t soon forget.

The party-goers at the Thanksgiving celebration I brought this to gobbled it up and begged for the recipe. I don’t understand how vegetables can taste so good, and frankly, I don’t really care. All I know is that I’m getting hungry.

Is it possible to want more leftovers? Apparently. Excuse me while I go make another batch. It doesn’t make sense and I love it.

Start by making your golden puree. I didn’t give exact measurements for the spices because I want to encourage sampling. Be the master of your domain. Taste as you go! It’s liberating. And delicious.

Now add to your baking dish of choice. I used a cast iron skillet because my baking dish of choice may or may not have been clean and heaven knows I do love my cast iron skillet. Smooth it out, making sure to dedicate a moment to appreciating the creaminess.

“Gee, I wish this had fewer marshmallows,” said no one ever. Darn it, this casserole could win a beauty pageant. Make sure to give yourself a generous helping. You’ve earned it! And this isn’t going to last long.

Butternut Squash Casserole [Vegan]






  • 1 large butternut squash
  • 2-3 tablespoons almond milk
  • Sweetener
  • Cinnamon
  • Salt and pepper
  • Curry powder
  • 1 cup vegan mini marshmallows


  1. Preheat oven to 450°F. Line a baking sheet with foil and set aside.
  2. Cut butternut squash in half lengthwise and scoop out seeds and flesh. Place the two halves on the baking sheet cut-side down on the prepared baking sheet and bake in the oven at 450°F for 1 hour and 30 minutes, or until soft, golden, and completely cooked through. Reduce oven temperature to 375°F.
  3. Scoop the squash flesh into a large bowl. Mash in the almond milk one tablespoon at a time until you reach your desired consistency, and add sweetener, cinnamon, salt, pepper, and curry powder to taste. Transfer to a blender or use an immersion blender and puree until smooth.
  4. Grease an 8-inch baking dish. Scoop the squash puree into the dish, top evenly with the mini marshmallows, and bake in the oven at 375°F until cooked through and golden on top. Broil for a minute or until the marshmallows are beautifully browned.

There are vegan marshmallows; Sweet & Sara brand, for example.

Um, marshmallows aren't vegan or vegetarian. They contain gelatin which is an animal product.
