Step 1: Prepare the Ingredients – To make the perfect scalloped potatoes, start by gathering your ingredients. You’ll need 5-6 medium-sized potatoes, thinly sliced, 3 tablespoons of butter, 3 tablespoons of flour, 2 cups of milk, 1 cup of shredded cheese (cheddar works great), 1 teaspoon of salt, ½ teaspoon of black pepper, and a pinch of garlic powder or nutmeg for extra flavor. Preheat your oven to 375°F (190°C) and lightly grease a 9×13 baking dish to prevent sticking.

Step 2: Create the Creamy Sauce – In a medium saucepan, melt the butter over medium heat. Whisk in the flour to create a smooth paste, cooking for about 1 minute to eliminate the raw flour taste. Slowly pour in the milk while whisking continuously until the mixture thickens into a creamy sauce. Stir in salt, pepper, and any additional spices you like. Finally, mix in half of the shredded cheese until melted and smooth. This sauce will give your scalloped potatoes their rich and comforting flavor.

Step 3: Assemble the Dish – Layer half of the sliced potatoes evenly on the bottom of the prepared baking dish. Pour half of the creamy cheese sauce over the potatoes, spreading it evenly to coat every slice. Repeat with the remaining potatoes and sauce, then sprinkle the top with the rest of the shredded cheese for a golden, bubbly finish. For an extra touch, add a light sprinkle of breadcrumbs or parmesan on top.

Step 4,: Bake to Perfection – Cover the dish with foil and bake for 30 minutes. After that, remove the foil and bake for another 25-30 minutes, or until the top is golden brown and the potatoes are fork-tender. Let the dish rest for 10 minutes before serving so the sauce can set. These scalloped potatoes pair beautifully with roasted chicken, steak, or even a fresh salad, making them the perfect side dish for any meal.
