A creamy, cheesy scalloped potatoes dish with a nutty Gruyere crust that is easy to make and perfect for cozy dinners or special occasions.

Ingredients

Scale
  • 3 pounds Yukon Gold or Russet potatoes, peeled and thinly sliced
  • 2 cups shredded Gruyere cheese
  • 1 cup shredded sharp Cheddar cheese (optional but recommended)
  • 4 tablespoons unsalted butter, divided
  • 3 tablespoons all-purpose flour
  • 2 cups whole milk, room temperature
  • 2 cloves garlic, minced
  • 1 small onion, finely chopped (optional)
  • 1 teaspoon salt, plus more to taste
  • ½ teaspoon freshly ground black pepper
  • 1 teaspoon fresh thyme, chopped (optional)
  • A pinch of freshly grated nutmeg

Instructions

  1. Preheat the oven to 375°F (190°C).
  2. Peel and thinly slice the potatoes to about 1/8 inch thickness using a mandoline or sharp knife. Rinse slices in cold water and pat dry.
  3. In a large saucepan, melt 2 tablespoons butter over medium heat. Add minced garlic and chopped onion, cooking until fragrant and translucent, about 3 minutes.
  4. Stir in the flour and cook for 1-2 minutes to form a roux.
  5. Slowly whisk in the whole milk, stirring continuously until the mixture thickens and coats the back of a spoon, about 5-7 minutes.
  6. Add salt, pepper, fresh thyme, and nutmeg. Remove from heat and stir in 1 ½ cups of shredded Gruyere and the cheddar cheese until melted and smooth.
  7. Butter a 9×13-inch baking dish with the remaining 2 tablespoons butter. Arrange a single layer of potato slices at the bottom, pour some cheese sauce over them, then repeat layering until all potatoes and sauce are used, finishing with sauce on top.
  8. Sprinkle the remaining ½ cup Gruyere evenly over the top.
  9. Cover the dish with foil and bake for 45 minutes. Remove the foil and bake for an additional 15 minutes until the top is golden and bubbly.
  10. Let the dish rest for 10 minutes before serving to allow layers to set.

Notes

If the top browns too fast, tent loosely with foil. Use a mandoline with safety guard to avoid injury. For gluten-free, substitute flour with gluten-free blend or cornstarch. For dairy-free, use plant-based milk and vegan cheese alternatives, adjusting cooking times as needed. Resting the dish before serving helps layers hold together.
