Ingredients:
- 4 large russet potatoes, peeled and thinly sliced
- 1 large onion, thinly sliced
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups whole milk
- 1 cup heavy cream
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon ground nutmeg
- 1 1/2 cups shredded cheddar cheese
- 1/2 cup grated Parmesan cheese
- Fresh parsley, chopped (for garnish)
Directions:
- Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish.
- In a medium saucepan, melt the butter over medium heat. Add the flour and cook, stirring constantly, for 1-2 minutes to form a roux.
- Gradually whisk in the whole milk and heavy cream. Cook, stirring frequently, until the mixture thickens and begins to bubble.
- Stir in the salt, black pepper, and ground nutmeg. Remove from heat and set aside.
- Arrange half of the sliced potatoes in an even layer in the prepared baking dish. Top with half of the sliced onions.
- Pour half of the cream sauce over the potatoes and onions. Sprinkle with half of the shredded cheddar cheese.
- Repeat the layers with the remaining potatoes, onions, cream sauce, and cheddar cheese. Top with the grated Parmesan cheese.
- Cover the baking dish with aluminum foil and bake in the preheated oven for 45 minutes. Remove the foil and bake for an additional 25-30 minutes, or until the potatoes are tender and the top is golden brown and bubbly.
- Let the scalloped potatoes cool for a few minutes before serving. Garnish with fresh chopped parsley.
