Cheesy Scalloped Potatoes Supreme
Cheesy Scalloped Potatoes Supreme is a creamy, comforting side dish made with thinly sliced Russet potatoes, rich cheese sauce, and a golden cheesy topping—perfect for family dinners or special occasions.
Ingredients
- 2 lbs Russet potatoes sliced ⅛-inch thick (use a mandoline slicer for even slices)
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups whole milk or half-and-half for extra richness
- 2 cups shredded sharp cheddar cheese divided
- 1 cup grated Parmesan cheese divided
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- ½ teaspoon smoked paprika optional, for depth of flavor
- Salt and pepper to taste
- Optional toppings: Fresh parsley chopped green onions, or crispy bacon
Instructions
- Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish to prevent sticking.
- Melt butter in a saucepan over medium heat. Whisk in flour and cook for 1-2 minutes. Gradually add milk, whisking constantly, until the sauce thickens (5-7 minutes).
- Remove from heat and stir in 1½ cups cheddar and ½ cup Parmesan cheese until smooth. Season with garlic powder, onion powder, smoked paprika (if using), salt, and pepper to taste.
- Layer potato slices in the prepared dish, overlapping slightly. Pour a thin layer of cheese sauce over the potatoes. Repeat layers, finishing with sauce on top. Gently press down to help the sauce seep into the potatoes.
- Sprinkle the remaining ½ cup cheddar and ½ cup Parmesan cheese on top for a golden, cheesy crust.
- Cover with foil and bake for 45 minutes. Remove foil and bake for an additional 15-20 minutes until potatoes are tender and the top is golden. If needed, loosely cover with foil during the last few minutes.
- Let the dish cool for 5-10 minutes before serving. Garnish with fresh parsley, green onions, or bacon bits for extra flavor.
