This twice-roasted squash with Parmesan butter and grains is a sophisticated vegetarian dish that celebrates deep, caramelised flavours. By roasting the squash whole for several hours, the flesh becomes incredibly tender and sweet before being mashed with rich butter and salty cheese. It is a slow-cooking process that requires minimal effort but delivers a truly luxurious texture, making it an excellent centrepiece for a weekend lunch or a seasonal dinner party.
Balanced by a bright, zesty grain salad featuring nutty barley or quinoa, this recipe offers a wonderful contrast of temperatures and textures. The addition of golden raisins and toasted pumpkin seeds provides a subtle sweetness and crunch that cuts through the richness of the Parmesan. It is a wholesome, fibre-rich meal that feels both comforting and elegantly refined, serving as a complete and nutritious vegetarian option.

How to make Twice-Roasted Squash with Parmesan Butter and Grains
Back to contentsPlace a rack in middle of oven; preheat to 149°C. Prick squash all over with the point of a sharp paring knife and arrange on a foil-lined rimmed baking sheet. Roast until very tender (knife should slide easily through the flesh), about 3 hours. Tear or cut squash in half and let sit until cool enough to handle.
Remove seeds from squash; discard. Scoop flesh into a medium bowl. Tear skin into 6 large (about 4x4") pieces and set aside on same baking sheet to be refilled later; discard any excess skin. Add grated Parmesan, butter, and lemon zest to bowl with flesh and mash together to combine; season with salt and pepper.
Carefully move rack to upper third of oven and increase oven temperature to 232°C. Divide mashed squash mixture among reserved pieces of skin and roast until top of flesh is beginning to brown, 10–12 minutes.
While the squash is roasting, whisk lemon juice, vinegar, oil, and honey in a large bowl. Add spring onions, grains, pumpkin seeds, and raisins to dressing and toss to coat.
Arrange squash on a platter and spoon grain mixture and dressing over. Top with shaved Parmesan.
Whole squash can be roasted 4 days ahead. Keep intact and chill.
