Potato and Parsnip Gratin
Preheat the oven to 350°F.
Peel and slice the potatoes and parsnips. Peel, halve and rub the garlic on the cut surfaces. Grease the baking dish with butter and layer the potatoes and parsnips in the dish. Season with salt, pepper and nutmeg. Sprinkle with thyme. Pour in the cream, until the vegetables are barely covered. Sprinkle with cheese and bake for 45 minutes, until golden brown. Cover with aluminum foil to prevent excess browning, if desired. Remove from the oven and serve immediately.
