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.

How to make Roasted Sweet Potato and Delicata Squash with Cranberry Agrodolce
Back to contentsPreheat 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.
