1. Pre-heat oven to 200°C. 2. Layer half the sliced potatoes over the bottom of a 2 litre capacity (8 cup) ceramic baking dish. Drizzle with a little of the olive oil, sprinkle with a little thyme and season lightly. 3. Cover with the beetroot and season as before. Repeat with the sweet potato and finally remaining potato. Pour cream over the layered vegetables and sprinkle with combined cheeses. 4. Cover gratin with a layer of baking paper and wrap with foil. 5. Bake in preheated oven 60-70 minutes or until a skewer passes through the vegetables without resistance. 6. Remove foil and paper and bake further 20-30 minutes or until top is golden. 7. Tip: You can speed up the baking by pre-cooking the unpeeled veggies for a couple of minutes in the microwave. ---------------------------------------------------------------------------
