Potato Gratin
Description
Who can resist this traditional scalloped potato dish? Make enough to ensure there's leftovers!
Method
Preheat oven to 180C. Grease an ovenproof dish with butter.
Arrange sliced potatoes and onions in layers over the base of the prepared dish. Dot with remaining butter and pour in the stock - if you are in a hurry you can reduce the cooking time by heating the stock first. Season wth salt and pepper to taste.
Ensure the potatoes are completely submerged in the stock. Press them down if you need to. Bake for 45 minutes or until potatoes are just tender and beginning to turn golden brown on top.
Sprinkle cheese on top, if using, and grill until golden.
