Parsnip and beer mustard gratin

Side Serves 6 1h 25 min
This easily made, creamy gratin is a good weeknight dinner on its own with just a green salad and crusty bread. It's also a lovely accompaniment to pork – be it roast, chops or sausages. You could add in some fried bacon lardons, or substitute the Parmesan for another hard cheese to keep this vegetarian. If you don't have beer mustard, any other wholegrain mustard will do – add a small pinch of chilli to get the equivalent effect.
