Sometimes the classics are the way to go. If you intolerant of dairy there are many alternatives, the easiest one is LACTOSE free products, or vegan substitutions. This is a favourite of mine with wonderful childhood memories of Sunday Roasts.

The last layers should be butter and cheese. On the stove top, bring the cream to a simmer. Pour cream over the potatoes. Place the potatoes in the oven and bake uncovered for 1 to 1 ½ hours. The potatoes will be easily pierced with a fork and the top browned.
