Preheat the oven to 180°C (fan 160°C).
Peel the sweet potatoes, parsnips, and beetroot. Slice them into thin, even rounds using a mandoline or a sharp knife. Place each type of vegetable into a separate bowl.
In a jug or small bowl, mix the cream with a little salt and pepper.
In each vegetable bowl, add one-third of the creamy mixture, 1 tsp parsley, and a portion of the Parmesan. Toss well to coat the slices.
Rub the cut side of the garlic clove over the base of an ovenproof dish, then sprinkle in a little Parmesan and parsley for extra flavour.
Arrange the vegetable slices upright in the dish, alternating colours for a pretty layered effect. Press them down gently so they stay in place.
