When it comes to comfort food, scalloped potatoes are always a crowd-pleaser. In this recipe, we’ll focus on creating a dreamy white sauce that envelops layers of potatoes and optional savory add-ins, like crispy bacon or caramelized onions, for a rich and cozy dish.
Ingredients
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups whole milk (warm or at room temperature)
- 1 teaspoon salt
- ½ teaspoon freshly ground black pepper
- ¼ teaspoon ground nutmeg (optional)
- 2 pounds potatoes, thinly sliced
- 1 cup shredded cheddar cheese (optional for topping)
- Optional add-ins (e.g., crispy bacon bits, sautéed onions, chopped fresh herbs)
Instructions
Begin by melting the butter in a medium saucepan over medium heat. Once melted, whisk in the flour, stirring constantly, to form a smooth paste (a roux). Cook this mixture for about one minute to remove any raw flour taste.
Gradually pour in the warm milk, whisking thoroughly to prevent lumps. Continue stirring as the sauce thickens for about 4–5 minutes. Season with salt, pepper, and a sprinkle of nutmeg if you like a hint of warmth.
Meanwhile, preheat your oven to 375°F (190°C). Butter or lightly grease a baking dish, then layer half of your sliced potatoes along the bottom. If you’re adding extras like bacon, onions, or herbs, scatter some over the first layer. Pour half of the creamy white sauce on top, letting it seep between the slices.
Layer the remaining potatoes and additional toppings, then cover with the remaining sauce. If you enjoy a cheesy finish, sprinkle shredded cheddar over the top. Cover the dish with foil and bake in the preheated oven for 30 minutes. Remove the foil and continue baking for another 20–25 minutes, or until the potatoes are fork-tender and the top is golden brown. Let the dish rest for a few minutes before serving.
