Roasted, Mashed Butternut Squash

This roasted mashed butternut squash is a wonderfully simple vegan side dish that celebrates the natural sweetness of winter veg. By roasting the squash in its skin, the sugars caramelise beautifully, creating a deep, savoury flavour that boiling simply cannot match. It serves as a versatile alternative to traditional mashed potatoes, offering a vibrant colour and a silky texture that pairs perfectly with Sunday roasts or hearty stews.

Preparing this dish is almost effortless, as the seeds are removed only after roasting, saving you the struggle of peeling tough raw skin. It is an excellent choice for batch cooking or meal prep, as it stays fresh in the fridge for several days. Whether you enjoy it as a nutritious base for a grain bowl or a comforting accompaniment to a midweek meal, this homemade mash is a healthy, seasonal staple.

Ingredients for Roasted, Mashed Butternut Squash

  • 1 medium butternut squash, 3 to 1.8kg , or other similar winter squash

  • Olive oil

  • Salt

Preheat the oven to 204°C.

Cut the squash in half lengthwise through the stem. (Don’t bother scooping out the seeds.) Rub the squash halves all over with olive oil and place each piece on a baking sheet, cut-side down. Roast for 25 minutes, then flip the squash and continue cooking until tender all over, another 10 to 30 minutes—you should be able to pierce the neck of the squash with a paring knife and meet very little resistance. Allow to cool, then scoop out the seeds and discard them. Use a spoon to scoop all of the flesh into a bowl and discard the skins. Coarsely mash the squash with a spoon or fork and season with salt. Packed in an airtight container, it will keep in the refrigerator for 3 to 4 days.
