All-Crust Sheet-Pan Scalloped Potatoes Recipe

 All-Crust Sheet-Pan Scalloped Potatoes take the classic creamy comfort of scalloped potatoes and give every slice a golden, crispy edge. Baked flat on a sheet pan instead of a deep dish, this version ensures every bite is crusty on top and perfectly tender underneath — ideal for serving a crowd or adding flair to a holiday meal.

Ingredients

  • 3 pounds russet or Yukon gold potatoes, peeled and thinly sliced (about ⅛ inch thick)

  • 2 tablespoons unsalted butter, melted (plus more for greasing)

  • 2 cups heavy cream

  • 1 cup whole milk

  • 2 garlic cloves, minced

  • 1 teaspoon salt

  • ½ teaspoon black pepper

  • ½ teaspoon ground nutmeg

  • 1½ cups shredded Gruyère cheese (or sharp cheddar)

  • ½ cup grated Parmesan cheese

  • 2 teaspoons fresh thyme leaves (optional, for garnish)

Cooking Time

  • Prep time: 20 minutes

  • Cook time: 40–45 minutes

  • Total time: about 1 hour

Serving

  • Serves 8

Instructions

  1. Preheat the Oven:

    Heat the oven to 400°F (200°C). Grease a large rimmed baking sheet (about 13×18 inches) generously with butter.

  2. Prepare the Cream Mixture:

    In a saucepan over medium heat, combine heavy cream, milk, garlic, salt, pepper, and nutmeg. Warm until it just begins to simmer, then remove from heat.

  3. Layer the Potatoes:

    Arrange the sliced potatoes in a single overlapping layer on the prepared sheet pan. Pour the warm cream mixture evenly over the top.

  4. Add Cheese:

    Sprinkle the Gruyère and Parmesan evenly across the potatoes. Drizzle with melted butter for extra crispness.

  5. Bake:

    Place in the oven and bake for 40–45 minutes, until the top is deep golden brown and crisp, and the potatoes are tender when pierced with a fork.

  6. Finish and Serve:

    Let rest for 10 minutes before slicing. Sprinkle fresh thyme over the top if desired. Cut into squares and serve warm.

Tips

  • For extra crisp edges, broil the pan for 2–3 minutes at the end of baking.

  • A mandoline slicer helps achieve thin, even potato slices.

  • You can add caramelized onions or crispy bacon between layers for more flavor.
