Roasted Autumn Vegetables

This vibrant roasted autumn vegetables dish celebrates the earthy flavours of the harvest season. By combining naturally sweet butternut squash and red-skinned sweet potatoes with the peppery note of roasted swede, you create a colourful and nutritious accompaniment to any main course. The roasting process caramelises the natural sugars in the root vegetables, which is then perfectly balanced by a sharp, zesty dressing of apple cider vinegar and fresh chives.

As a versatile vegan side dish, it is an excellent addition to a traditional Sunday roast or a plant-based festive spread. The inclusion of cayenne pepper provides a very subtle warmth, while the raw red onion added at the end provides a crisp texture. This recipe is also highly practical, as the vegetables can be roasted in advance and reheated just before serving without losing their delicious flavour.
