Ingredients
Scale
Potatoes
- 2 pounds russet or Yukon Gold potatoes, peeled and thinly sliced
Cheese Sauce
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 2 cups whole milk
- 1 cup heavy cream
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 2 cups shredded sharp cheddar cheese
- 1/2 cup shredded mozzarella cheese
Topping
- 1/4 cup grated Parmesan cheese
- Chopped parsley for garnish (optional)
Instructions
- Preheat and Prepare Dish: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking and ensure easy cleanup.
- Make the Cheese Sauce: In a medium saucepan over medium heat, melt the unsalted butter. Whisk in the flour and cook for 1 to 2 minutes to create a roux, which will thicken the sauce. Slowly add the whole milk and heavy cream while whisking constantly to keep the mixture smooth. Continue stirring until the sauce thickens slightly, about 5 minutes. Season with salt, black pepper, garlic powder, and onion powder. Then, stir in the shredded cheddar and mozzarella cheeses until fully melted and smooth. Remove the sauce from heat.
- Layer the Potatoes and 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. Repeat the layering with the remaining potatoes and cheese sauce. Finally, sprinkle the grated Parmesan cheese evenly over the top.
- Bake Covered: Cover the baking dish with foil and bake in the preheated oven for 40 minutes. This initial baking steams the potatoes to tender perfection under the foil.
- Bake Uncovered: Remove the foil and continue baking for another 20 to 25 minutes, or until the top turns golden brown and the potatoes can be easily pierced with a fork.
- Rest and Garnish: Allow the scalloped potatoes to rest for 10 minutes to set before serving. Optionally, garnish with chopped parsley for a fresh, vibrant finish.
Notes
- For extra flavor, consider layering in sautéed onions or cooked bacon between the potato layers.
- You can prepare this dish a day ahead and reheat it before serving for convenience without sacrificing quality.
