Preheat the oven to 200°C and lightly grease a casserole dish with butter or oil.
Drain and thinly slice the Love Potatoes.
Layer the potatoes, onion and cheddar cheese. You should be able to get about two complete layers. Season each layer with salt and pepper. Pour the cream over the final layer and sprinkle with more cheddar or parmesan!
Bake in the oven for 40 minutes or until golden and crunchy on top!
