Ingredients

  • 2 lb Russet or Yukon Gold potatoes, peeled and very thinly sliced (about 1/8 inch thick)
  • 4 tablespoon unsalted butter
  • 4 tablespoon all-purpose flour
  • 2 cup whole milk
  • 0.5 cup heavy cream
  • 1 teaspoon salt
  • 0.25 teaspoon freshly ground black pepper
  • 0.25 teaspoon freshly grated nutmeg

Instructions

  1. 1.

    Preheat your oven to 375°F (190°C). Lightly butter a 2-quart baking dish (an 8x8 inch square dish or a similar oval/round dish works well for 4 servings).

  2. 2.

    Prepare the potatoes: Peel the potatoes and slice them very thinly and uniformly, aiming for about 1/8 inch thickness. A mandoline slicer is highly recommended for achieving consistent slices, which ensures even cooking.

  3. 3.

    Make the cream sauce: In a medium saucepan, melt the butter over medium heat. Once melted, whisk in the all-purpose flour and cook for 1-2 minutes, stirring constantly, to create a smooth roux. Do not let it brown.

  4. 4.

    Gradually whisk in the whole milk and heavy cream until the mixture is smooth and lump-free. Bring the sauce to a gentle simmer, whisking continuously, until it thickens slightly, typically 3-5 minutes.

  5. 5.

    Remove the sauce from the heat and stir in the salt, freshly ground black pepper, and freshly grated nutmeg. Taste the sauce and adjust seasoning if necessary.

  6. 6.

    Assemble the dish: Arrange about one-third of the thinly sliced potatoes in an even layer at the bottom of the prepared baking dish. Pour approximately one-third of the cream sauce evenly over the potatoes.

  7. 7.

    Repeat the layering process two more times, creating a total of three potato layers with sauce in between, ending with a generous layer of cream sauce on top. Ensure the top layer of potatoes is mostly covered by sauce to prevent them from drying out during baking.

  8. 8.

    Bake, covered: Cover the baking dish tightly with aluminum foil. Bake in the preheated oven for 45 minutes.

  9. 9.

    Bake, uncovered: Carefully remove the aluminum foil. Continue baking for an additional 25-30 minutes, or until the potatoes are fork-tender, and the top is beautifully golden brown and bubbly.

  10. 10.

    Rest: Remove the Classic Scalloped Potatoes from the oven and let them rest for 10-15 minutes before serving. This resting period allows the sauce to set, making it easier to serve and ensuring a creamy texture.

Tips

  • 💡**Uniform Slicing is Key**: For evenly cooked potatoes, consistent slice thickness is crucial. A mandoline slicer is highly recommended; otherwise, take your time to slice by hand as uniformly as possible, aiming for 1/8 inch thick.
  • 💡**Don't Rush the Roux**: When making the cream sauce, cook the butter and flour for a full minute or two to eliminate any raw flour taste, but avoid browning it to maintain a light-colored sauce.
  • 💡**Resting Time is Essential**: Allowing the scalloped potatoes to rest for 10-15 minutes after baking is vital. This helps the creamy sauce to set properly, preventing it from being too runny when you serve it.
  • 💡**Potato Choice Matters**: While both Russet and Yukon Gold potatoes work well, Russets tend to be starchier, contributing to a slightly creamier sauce, whereas Yukon Golds hold their shape a bit more while still providing a rich, creamy texture.
