Ingredients
Scale
- 3 lbs Russet potatoes, peeled and thinly sliced
- 4 tablespoons unsalted butter
- 1/4 cup all-purpose flour
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon nutmeg
- 2 cups whole milk
- 1 cup heavy cream
- 2 cups shredded sharp cheddar cheese, divided
- 1 cup shredded Gruyère cheese
Instructions
- Preheat your oven to 375 degrees F. Grease a 9×13 inch baking dish with butter.
- In a medium saucepan, melt the butter over medium heat. Whisk in the flour, salt, pepper, and nutmeg. Cook this roux for one minute, stirring constantly.
- Slowly whisk in the whole milk and heavy cream until the mixture is smooth. Continue cooking, stirring often, until the sauce thickens enough to coat the back of a spoon, about 5 to 7 minutes. Do not let it boil rapidly.
- Remove the sauce from the heat. Stir in 1 1/2 cups of the cheddar cheese and all of the Gruyère cheese until melted and smooth. This is your cheesy potato sauce.
- Arrange half of the thinly sliced potatoes in an even layer in the prepared baking dish. Pour half of the cheese sauce evenly over the potatoes.
- Top with the remaining potatoes, followed by the remaining cheese sauce.
- Cover the baking dish tightly with aluminum foil. Bake for 45 minutes.
- Remove the foil. Sprinkle the remaining 1/2 cup of cheddar cheese over the top.
- Return the dish to the oven, uncovered, and bake for another 15 to 20 minutes, or until the potatoes are tender when pierced with a fork and the top is golden brown and bubbly.
- Let the scalloped potatoes rest for 10 minutes before serving.
Notes
- For the best texture, slice your potatoes uniformly, about 1/8 inch thick. A mandoline slicer works well for this.
- You can assemble this dish up to 24 hours ahead of time. Cover and refrigerate, then add 10-15 minutes to the initial covered baking time.
- This dish pairs well with roasted chicken or holiday ham.
