Ingredients
  

  • 3 pounds russet potatoes peeled and thinly sliced
  • 2 cups heavy cream
  • 1 cup whole milk
  • 3 tablespoons butter
  • 2 cloves garlic minced
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon ground nutmeg optional
  • 2 cups shredded sharp cheddar cheese
  • 1 cup shredded Gruyère cheese
  • 1/4 cup grated Parmesan cheese

Instructions
 

Preheat Oven

  • Preheat oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter or oil.

Prepare Cream Sauce

  • In a saucepan, combine heavy cream, milk, butter, garlic, salt, pepper and nutmeg. Heat gently.

Cook Sauce Slightly

  • Whisk mixture until warm and slightly thickened. Do not boil; keep creamy for best results.

Layer Potatoes

  • Place a layer of sliced potatoes in the bottom of the baking dish evenly.

Add Cheese Layer

  • Sprinkle shredded cheddar and Gruyère over the potato layer. Add some Parmesan too.

Repeat Layers

  • Continue layering potatoes and cheese until all ingredients are used. Pour cream mixture over layers.

Cover and Bake

  • Cover the dish with foil. Bake in preheated oven for 35 minutes.

Remove Foil and Brown

  • Remove foil. Bake an additional 10 minutes until top is golden and bubbly.

Cool Slightly and Serve

  • Let the potatoes cool for 5 minutes. Serve warm with your favorite main dish.

Notes

  • Use thin potato slices for even cooking.
  • Use sharp cheddar and Gruyère for rich flavor.
  • Pour warm cream sauce over potatoes for best texture.
  • Cover with foil to prevent burning top layer.
  • Let it rest 5 minutes before serving for easier slicing.
