This wild mushroom and potato gratin is a luxurious vegetarian side dish that brings a deep, earthy flavour to the dinner table. By layering buttery Yukon Gold potatoes with sautéed woodland mushrooms and a generous amount of double cream, you create a dish that is both sophisticated and immensely comforting. The mushrooms add a meaty texture and savoury notes that balance the creamy richness of the potatoes, making it a standout accompaniment for a Sunday roast or a special occasion dinner.
