Yams with Crispy Skins and Brown-Butter Vinaigrette

This elegant vegetarian dish transforms humble red-skinned sweet potatoes into a sophisticated side that is perfect for a Sunday roast or a festive dinner party. By roasting the potatoes whole, the flesh stays incredibly sweet and creamy, providing a beautiful contrast to the salty, deep-fried skins. The addition of a tangy Dijon mustard and vinegar dressing cuts through the richness, creating a balanced and autumnal flavour profile.

Technically simple but visually impressive, this recipe is an excellent choice for those looking for a modern twist on classic root vegetables. The components can be prepared slightly in advance, making it a stress-free addition to a busy kitchen. Serve these potatoes alongside a crisp green salad or as a hearty accompaniment to your favourite meat-free main course for a truly comforting homemade meal.
