This recipe is originally from an issue of Bon Apetit. It's very rich and makes a great side dish for a special meal. If you have a Cuisinart, use it, it will make the recipe a snap by eliminating the tedious slicing of the potatoes. Make sure to use a high quality of Gruyere cheese, some are very oily. I use Boar's Head here at home. Also make sure to stick to the amount of cheese listed as too much will make the dish greasy - even if you do use a high quality cheese.
- Preheat oven to 400 degrees and generously butter a 13x9x2 glass baking dish.
- Arrange half of potato slices in bottom of prepared dish, overlapping slightly.
- Sprinkle generously with salt and pepper to taste.
- Spread half of creme fraiche over the potatoes and sprinkle with 1/2 of the Gruyere cheese.
- Top with remaining potatoes, again overlapping slightly, sprinkle with salt and pepper to taste.
- Spread remaining creme fraiche on top, and sprinkle with remaining Gruyere cheese.
- Bake uncovered for 30 minutes and then reduce oven temperature to to 350 degrees.
- Continue to bake the gratin until the potatoes are tender and the top is a nice golden brown, about 45 minutes.
- Remove from the oven and let set for 10-15 minutes.
- Sprinkle with parsley and scallions.
