A Hearty and delicious recipe for potato gratin bake, this dish is great served with sour cream.
Preheat oven to 350 degrees F. Lightly grease a 2L (8-cup) capacity baking dish with butter.
Thinly slice the potatoes crossways.
Arrange a layer of potato slices over the base of the dish, overlapping slightly.
Whisk flour into cream so no lumps remain.
Drizzle cream over potatoes and sprinkle with onions and 2 tablespoons cheese.
Season with salt and pepper. Repeat to make 3 more layers, finishing with a layer of cheese.
Bake in oven for 1 hour or until the potato is tender and the top is golden.
