Line the casserole dish with a thin film of butter. Overlap the sliced potatoes covering only the edge of the previous potato in a straight line, side by side. Sprinkle with salt and pepper. Place a 3rd of the onions, garlic and thyme scattered on top. Sprinkle with a 3rd of the gruyere all over that.
Pour 3/4 cup of cream on top of that and repeat 2 more times, ending with the cheese. Cover with foil and bake 1 hour.
Then take off the foil and turn the oven down to 400 and bake another 40 minutes. With a knife, see if the potatoes are cooked by stabbing the casserole. If they feel a little crunchy, place back in the oven covered for another 1/2 hour. Cool for 15 minutes.
