This Hasselback butternut squash combines the magic of winter squash and simplicity. Inspired by a famous potato dish, this recipe makes an amazing vibrant centerpiece or side dish at a holiday table.

Hasselback butternut squash served on an oval platter with chopped pistachios and fresh parsley.

One of the reasons I love the holiday season is for pumpkins and winter squash. From plant-based mac and cheese to creamy butternut squash and carrot soup, there are some incredible ways to utilize this seasonal vegetable!

And as much as I like potatoes, I don’t think they should be the only ones to benefit from the Hasselback technique. Making slices partway through is an awesome way to create texture, speed up and even out the cooking process, and add seasoning into the heart of your produce.
