Add Cheese and Cream:
Sprinkle a portion of the grated Parmesan and Gruyere cheeses over the layer of potatoes. Drizzle some of the cream mixture over the cheese.
Repeat the Layers:
Repeat the process of layering potatoes, cheese, and cream until you’ve used up all the ingredients. Make sure to finish with a layer of cheese and cream on top.
Bake:
Cover the baking dish with aluminum foil and bake in the preheated oven for about 45-50 minutes. Then, remove the foil and continue baking for an additional 15-20 minutes, or until the top is golden brown and the potatoes are tender when pierced with a fork.
Serve:
Remove the Potatoes Delmonico from the oven and let it cool slightly before serving. Garnish with chopped fresh parsley for a burst of color and added freshness.
