Ingredients

  • 4 large russet potatoes, thinly sliced
  • 2 cups heavy cream
  • 1 ½ cups shredded cheddar cheese
  • ½ cup grated Parmesan cheese
  • 3 tablespoons unsalted butter
  • 3 cloves garlic, minced
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon onion powder
  • ½ teaspoon paprika
  • ½ teaspoon dried thyme (optional)
  • 1 tablespoon all-purpose flour
  • 1 cup whole milk
  • ½ teaspoon mustard powder (optional)
  • Fresh parsley for garnish

Instructions

  1. Preheat the Oven – Set your oven to 375°F (190°C) and grease a baking dish with butter or non-stick spray.
  2. Prepare the Potatoes – Wash, peel, and slice the potatoes into thin rounds (about ⅛-inch thick) using a sharp knife or mandoline slicer.
  3. Make the Creamy Sauce – In a saucepan over medium heat, melt the butter and sauté the minced garlic until fragrant. Add the flour and whisk continuously to create a smooth roux. Slowly pour in the milk and heavy cream, stirring constantly until thickened.
  4. Season the Sauce – Add salt, black pepper, onion powder, paprika, thyme, and mustard powder for enhanced flavor. Stir well to combine.
  5. Add the Cheese – Reduce the heat to low and mix in 1 cup of shredded cheddar cheese and Parmesan cheese, stirring until melted and smooth. Remove from heat.
  6. Layer the Potatoes – Arrange half of the sliced potatoes in an even layer in the prepared baking dish. Pour half of the creamy cheese sauce over the potatoes, ensuring even coverage.
  7. Repeat the Layers – Add the remaining potato slices and pour the rest of the cheese sauce over the top, making sure all potatoes are coated.
  8. Top with More Cheese – Sprinkle the remaining ½ cup of cheddar cheese evenly over the dish for a golden, cheesy crust.
  9. Bake to Perfection – Cover the dish with foil and bake for 40 minutes. Remove the foil and continue baking for another 25-30 minutes until the top is golden and the potatoes are tender.
  10. Rest and Serve – Let the scalloped potatoes rest for 10 minutes before serving to allow the sauce to thicken. Garnish with fresh parsley and serve warm.
