Instructions
Wash and peel the potatoes and chop into thin round slices.
Grease the casserole dish and layer the sliced potatoes across.
Add any optional ingredients (bacon lardons, onions, etc) in between the potato slices.
Mix the crème fraîche, butter, garlic, nutmeg, salt and pepper in a bowl.
Add the mixture over the top of the potatoes in the casserole.
Sprinkle the grated cheese on top.
Add a few leaves of parsley on top for decoration.
Cook in preheated oven for 25 minutes at 200C° (400F°) until potatoes and cheese are lightly browned.
Notes
If in a hurry, you can lightly boil the potatoes the night before to cut down the cooking time in the oven. Put in the Instant pot for 8 minutes high pressure with quick release, peel them and then put them overnight in the fridge. The next day, slice the potatoes, add the sauce and put in preheated oven for 20 minutes. (Precook the bacon if you are adding it to the recipe.)
