  • Lay out 1/3 of the potatoes in a baking dish and pour on 1/3 of the cream. Sprinkle on 1/3 of the gruyere. Repeat, laying out another 1/3 of the potatoes and 1/3 of the cream and 1/3 of the gruyere. Finish with the remaining potatoes, pushing them down slightly to submerge in the cream.

  • When the potatoes are soft and tender, remove from the oven and take off the foil. Top with the remaining grated gruyere cheese and bake until the cheese is melty and golden, about another 10-15 minutes. Remove and let rest for 5-10 minutes then enjoy.
