Ingredients

Scale

Potatoes

  • 1 kg potatoes, peeled and thinly sliced (approx. 1/8-inch thick)

Cheese

  • 1 cup mozzarella cheese, shredded
  • ¾ cup cheddar cheese, shredded

Cream Sauce

  • 1 cup heavy cream
  • 1.5 cups whole milk, gently warmed
  • 2 tbsp unsalted butter, melted
  • 2 tbsp all-purpose flour
  • 1 tsp onion powder
  • 1 tsp garlic powder
  • Salt, to taste
  • Black pepper, to taste

Garnish

  • Fresh parsley or dill, chopped

Instructions

  1. Prepare Potatoes: Peel 1 kg of potatoes and slice them thinly (approximately 1/8-inch thick) using a mandoline or sharp knife. Pat dry if desired to remove excess starch, ensuring even cooking and a better texture.
  2. Prepare Cheese and Milk: Shred 1 cup mozzarella cheese and ¾ cup cheddar cheese. Gently warm 1.5 cups whole milk in a small saucepan until it is just warm to the touch, which helps blend smoothly into the sauce.
  3. Make Cream Sauce Base: In a large saucepan or Dutch oven, melt 2 tablespoons of unsalted butter over medium heat. Whisk in 2 tablespoons of all-purpose flour and cook for 1-2 minutes until the roux turns pale golden and loses the raw flour taste, forming the thickening base of the sauce.
  4. Finish Cream Sauce: Gradually whisk the warmed milk into the roux a little at a time to prevent lumps. Then whisk in 1 cup heavy cream. Continue whisking over medium heat until the sauce starts to gently simmer and thickens enough to coat the back of a spoon. Remove from heat.
  5. Season Sauce: Stir in 1 teaspoon onion powder, 1 teaspoon garlic powder, salt, and black pepper to taste. Adjust the seasoning by tasting, keeping in mind that the potatoes will absorb some of the flavors.
  6. Assemble First Layer: Preheat your oven to 375°F (190°C). Generously grease a 9×13-inch baking dish with butter. Spread about one-third of the sliced potatoes in a slightly overlapping layer evenly on the bottom of the dish.
  7. Add Sauce and Cheese: Pour about one-third of the prepared cream sauce evenly over the potato layer. Sprinkle approximately one-third of the combined shredded mozzarella and cheddar cheese evenly over the sauce.
  8. Complete Layers and Top: Repeat layering two more times with the remaining potatoes, sauce, and cheese, ensuring the final potato layer is fully covered by sauce. Sprinkle the remaining cheese generously on top for a golden, bubbling crust.
  9. Bake Covered: Cover the dish tightly with aluminum foil to create steam and bake in the preheated oven for 60 minutes. This helps the potatoes become tender and the flavors meld.
  10. Bake Uncovered: Carefully remove the foil and continue baking uncovered for 30-45 minutes until the top is golden brown, bubbly, and the potatoes are very tender when pierced with a fork or knife.
  11. Rest and Serve: Remove the scalloped potatoes from the oven and loosely tent with foil. Let rest on a wire rack for 15-20 minutes to allow the sauce to thicken and set. Garnish with fresh chopped parsley or dill before serving warm.

Notes

  • Use a mandoline or very sharp knife for even potato slices to ensure uniform cooking.
  • Patting potatoes dry before layering can help reduce excess moisture, preventing a watery casserole.
  • You can substitute half-and-half for heavy cream to lighten the dish slightly but expect a less rich texture.
  • Letting the dish rest after baking thickens the sauce, making it easier to serve and enhances flavor melding.
  • Fresh herbs like parsley or dill add a pop of color and fresh contrast to the rich casserole.
