​Root Vegetable Gratin

This root vegetable gratin makes a marvellous vegetarian Christmas side dish and is a nice change up from the usual roasted vegetables. Unlike most gratins, where you stack the vegetables on top of each other, we layer them vertically so you wind up with lots of crispy edges and a beautiful display. It's a lovely dish for a celebratory feast but simple enough to make any day of the week. Feel free to mix up the vegetables - in the summer this is glorious with courgettes.
