Ingredients:
- 2 lbs (900g) russet potatoes, thinly sliced
- 1 ½ cups heavy cream
- 1 cup whole milk
- 2 garlic cloves, minced
- 1 teaspoon fresh thyme (or ½ teaspoon dried)
- 1 cup Gruyère cheese, grated
- ½ cup Parmesan cheese, grated
- 3 tablespoons unsalted butter
- Salt and black pepper to taste
- Fresh parsley, chopped (for garnish)
Instructions:
- Preheat Oven: Set your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter.
- Prepare the Cream Mixture: In a saucepan, heat the heavy cream, milk, minced garlic, thyme, salt, and pepper over medium heat. Let the mixture warm through, but do not let it boil. Stir occasionally to ensure the garlic infuses the cream evenly.
- Layer the Potatoes: Arrange half of the thinly sliced potatoes in a single layer in the greased baking dish. Season the layer lightly with salt and pepper.
- Add Cheese: Sprinkle half of the Gruyère and Parmesan cheeses over the first layer of potatoes.
- Pour Cream Mixture: Pour half of the warm cream mixture evenly over the cheese and potatoes.
- Repeat Layers: Repeat with the remaining potatoes, followed by the remaining cheese and cream mixture. Dot the top with small pieces of butter for extra richness.
- Bake: Cover the dish with aluminum foil and bake in the preheated oven for 45 minutes. Remove the foil and continue baking for another 20-25 minutes, or until the top is golden and crispy, and the potatoes are tender when pierced with a fork.
- Garnish and Serve: Once out of the oven, allow the gratin to rest for 10 minutes. Garnish with freshly chopped parsley before serving for an added pop of color and flavor.
