Preheat the oven to 180C.
Grease an ovenproof dish with butter and place a layer of potato slices on the base.
Season with salt and freshly ground black pepper and sprinkle over with a pinch of rosemary and a little cheese.
Repeat this process, alternating between layers of potato and celeriac, setting aside a 1/3 of the cheese.
Bring the cream, milk, bay leaf and garlic to the boil and pour over the celeriac making sure that it filters all the way down to the bottom of the dish.
Sprinkle over a little grated nutmeg then top with the remaining cheese.
Bake for an hour until the celeriac and potatoes are tender and bubbling and golden brown on top.
This is great with roast beef or lamb.
