Ingredients:
- 2 pounds (900g) potatoes, preferably Yukon Gold or Russet, peeled and thinly sliced (about 1/8 inch thick)
- 2 cups (480 ml) heavy cream
- 1 cup (240 ml) whole milk
- 3 cloves garlic, minced
- 1 teaspoon salt
- 1/2 teaspoon freshly ground black pepper
- 1/4 teaspoon ground nutmeg
- 1 cup (100g) grated Gruyère or Swiss cheese
- 1/2 cup (50g) grated Parmesan cheese
- Fresh chives or parsley, chopped, for garnish
Instructions:
- Preheat the Oven:
- Preheat your oven to 350°F (175°C). Grease a large baking dish (about 9×13 inches) with butter.
- Prepare the Potatoes:
- Peel and thinly slice the potatoes using a sharp knife or a mandoline for even slices.
- Make the Cream Mixture:
- In a saucepan, combine the heavy cream, milk, minced garlic, salt, pepper, and nutmeg. Heat over medium heat until the mixture is warm and well combined, but do not let it boil.
- Layer the Potatoes:
- Arrange a layer of the sliced potatoes at the bottom of the prepared baking dish. Pour a little of the cream mixture over the potatoes and sprinkle with a small amount of Gruyère cheese.
- Continue Layering:
- Repeat the layering process until all the potatoes, cream mixture, and Gruyère cheese are used up. Finish with a layer of cream and the remaining Gruyère cheese on top.
- Add Parmesan and Bake:
- Sprinkle the grated Parmesan cheese evenly over the top layer. Cover the dish with aluminum foil and bake in the preheated oven for 45 minutes.
- Remove Foil and Finish Baking:
- After 45 minutes, remove the foil and continue to bake for an additional 20-25 minutes, or until the top is golden brown and the potatoes are tender when pierced with a fork.
- Garnish and Serve:
- Once baked, remove the gratin from the oven and let it sit for a few minutes. Garnish with chopped chives or parsley before serving.
Notes:
- For extra richness, you can add a few pats of butter on top before baking.
- Gruyère is the traditional cheese used in this dish, but you can substitute it with Swiss, Cheddar, or another melting cheese if preferred.
