Roasted Sweet Potato and Delicata Squash with Cranberry Agrodolce

This vibrant roasted sweet potato and delicata squash dish is a celebration of autumnal flavours and textures. The natural sweetness of the root vegetables is beautifully enhanced by high-heat roasting, which coaxes out deep caramelisation and charred edges. Delicata squash is a particular favourite for busy cooks, as its thin skin becomes perfectly tender in the oven, removing the need for any fiddly peeling. It is a sophisticated vegan centrepiece or side that brings a pop of colour to any seasonal table.

The dish is finished with a homemade cranberry agrodolce, a traditional Italian-style sweet and sour sauce. By simmering fresh cranberries with red wine vinegar and sugar, you create a glossy, piquant glaze that cuts through the richness of the roasted vegetables. This recipe is an excellent choice for a festive roast or a hearty Sunday lunch, offering a complex balance of heat from the chilli flakes and brightness from the vinegar. Serve it warm on a large platter for a truly inviting presentation.

Ingredients for Roasted Sweet Potato and Delicata Squash with Cranberry Agrodolce

  • 4 delicata squash (about 1.8kg total), halved crosswise, seeded, sliced into 1/2"-thick rings

  • 1.4kg sweet potatoes (about 7 small or 5 medium), cut into 3/4"-thick rounds

  • 2 tablespoons extra-virgin olive oil

  • 1 teaspoon crushed red pepper flakes

  • 2 1/2 teaspoons kosher salt, divided

  • 15 small sprigs thyme, divided

  • 230g fresh cranberries

  • 475ml red wine vinegar

  • 350ml sugar

Preheat oven to 218°C. Toss squash, sweet potatoes, and oil in a very large bowl. Add red pepper flakes and 2 teaspoons salt and toss to combine. Arrange on a rimmed baking sheet with 12 thyme sprigs. Roast, tossing once halfway through, until squash is golden brown and fork-tender, about 1 hour.

Meanwhile, cook cranberries, vinegar, sugar, and remaining 3 thyme sprigs and 1/2 teaspoons salt in a medium saucepan over medium heat, stirring occasionally, until cranberries are soft and sauce is thick and syrupy, about 35 minutes.

Transfer vegetables to a platter, then drizzle some agrodolce over. Serve remaining agrodolce alongside.
