The maligned, knobbly vegetable known as celeriac or celery root is very mild in flavour, especially when cooked (like a slightly nutty potato). Paired with standard potatoes and sliced onions in a scalloped-style dish, it's so delectable you'll wonder why you haven't tried it before!

Ingredients Nutrition


  1. Preheat your oven to 400°F.
  2. Place the potatoes, celeriac and onion in a bowl and season generously with salt and pepper.
  3. Add the garlic, 3/4 of the cheese, milk and sour cream and the rosemary.
  4. Mix everything around to mix all the flavours. Pour into a casserole dish.
  5. Sprinkle over the extra cheese, and bake in the preheated oven for 50 minutes, or until tender and golden. Remove rosemary stalks and serve.
