Ingredients
Scale
- 3 lbs Russet potatoes, peeled and thinly sliced
- 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 1/2 cups Gruyere cheese, shredded
- 1/2 cup Parmesan cheese, grated
- 2 tablespoons unsalted butter, softened (for dish)
Instructions
- Preheat your oven to 375°F (190°C). Butter a 9×13 inch baking dish generously.
- Rub the cut surfaces of the garlic cloves onto the inside of the prepared baking dish for flavor.
- In a medium saucepan, gently warm the heavy cream, milk, salt, pepper, and nutmeg. Do not boil.
- In a large bowl, toss the sliced potatoes with the minced garlic.
- Pour half of the warm cream mixture over the potatoes, stirring gently to coat.
- Stir in 1 cup of the Gruyere cheese and all of the Parmesan cheese into the potato mixture.
- Transfer the potato mixture to the prepared baking dish, spreading evenly.
- Pour the remaining cream mixture evenly over the potatoes.
- Top the dish with the remaining 1/2 cup of Gruyere cheese.
- 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.
- Let the potatoes rest for 10 minutes before serving.
Notes
- Slice potatoes very thinly and uniformly for even cooking. A mandoline slicer works best.
- If the top browns too quickly, loosely cover the dish with foil for the last 20 minutes of baking.
- For an extra savory flavor, substitute half of the Gruyere with sharp white cheddar.
- You can prepare the dish up to the point of baking, cover, and refrigerate for up to 24 hours. Add 10-15 minutes to the baking time if cooking straight from the refrigerator.
