Classic Pommes Boulangère - French Gratin Potatoes

READY IN: 1hr 45mins
Recipe by French Tart

This classic French potato gratin dish literally translates as "Potatoes in the Style of the Baker's wife". The story is, that in the past, a French family would prepare these potatoes and then take them to the local boulangerie, the baker, to be cooked in the even heat of his oven, hence the name. Any sort of good quality stock will do, chicken, lamb, beef or vegetable. For a richer taste, a ratio of 50% hot stock and hot milk/cream can be used. If using lamb stock, it is nice to sprinkle the top of the potatoes with fresh Rosemary, and I often add a sprig of thyme to my potatoes when baking them. I have found that melted butter gives a better result than dotting butter, no burned and upturned edges anymore!

I made this exactly as written using homemade stock and yukon gold potatoes. It was good but I agree with a previous reviewer and think it would be enhanced with the addition of some tasty cheese. The instructions don't mention when to add the rosemary and thyme so I sprinkled some on top of the casserole before baking (almost forgot to add it or I would probably have added it to the stock).
