Slow-Cooked Winter Squash with Sage and Thyme

This roasted winter squash with sage and thyme is a masterclass in slow-cooked simplicity. By gently roasting the squash in a generous amount of extra-virgin olive oil alongside woody herbs and garlic, the flesh becomes incredibly buttery and infused with savoury depth. The addition of white wine vinegar at the end cuts through the richness, providing a bright finish that perfectly balances the natural sweetness of the delicata or acorn squash.

As a versatile vegan side dish, this recipe is ideal for a Sunday roast or a quiet midweek supper. It is naturally gluten-free and packed with vitamins, making it a healthy addition to any autumn or winter menu. Serve it alongside hearty grains or as part of a festive spread for a sophisticated yet effortless vegetable centrepiece.
