Ingredients
Scale
- 3 pounds Russet potatoes, peeled and thinly sliced
- 1 tablespoon unsalted butter, softened (for greasing dish)
- 3 cloves garlic, minced
- 2 cups heavy cream
- 1 cup whole milk
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon nutmeg
- 1 cup Gruyere cheese, shredded
- 1/2 cup Parmesan cheese, grated
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with the softened butter.
- In a medium saucepan, combine the heavy cream, whole milk, minced garlic, salt, pepper, and nutmeg. Heat the mixture over medium heat until it just begins to simmer around the edges. Do not boil. Remove from heat.
- Gently stir in half of the Gruyere cheese and all of the Parmesan cheese into the cream mixture until melted and smooth.
- Arrange half of the thinly sliced potatoes in an even layer in the prepared baking dish.
- Pour half of the warm cream mixture evenly over the potatoes.
- Layer the remaining potatoes on top. Pour the remaining cream mixture over this second layer. Gently press down on the potatoes to help them submerge slightly.
- Sprinkle the remaining Gruyere cheese evenly over the top layer.
- Bake for 60 to 75 minutes, or until the potatoes are tender when pierced with a fork and the top is golden brown and bubbly. If the top browns too quickly, loosely cover it with foil for the last 15 minutes.
- Let the gratin rest for 10-15 minutes before slicing and serving. This allows the sauce to set.
Notes
- Use Russet potatoes for the best texture as they absorb the cream well.
- Slice your potatoes uniformly, about 1/8 inch thick, for even cooking. A mandoline slicer helps here.
- For extra flavor, rub the inside of the baking dish with a cut garlic clove before buttering.
- If you do not have Gruyere, Swiss cheese is a suitable substitute.
