Ingredients

Scale

Potatoes and Seasoning

  • 3 pounds potatoes, thinly sliced
  • 1 teaspoon salt
  • 1 teaspoon pepper
  • 1 teaspoon fresh thyme

Dairy and Flavor

  • 1 head garlic, peeled and crushed
  • 4 tablespoons butter, thinly sliced
  • 2 cups Gruyere cheese, shredded
  • 1 ½ cups half and half or whipping cream

Instructions

  1. Preheat and Prepare Dish: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish or a large round cast iron skillet to prevent sticking and ensure even cooking.
  2. Layer Butter: Place the thinly sliced butter evenly across the bottom of the prepared baking dish to form a flavorful base for the potatoes.
  3. First Potato Layer: Arrange about one third of the thinly sliced potatoes over the butter layer. Evenly spread one third of the crushed garlic and one third of the shredded Gruyere cheese atop the potatoes.
  4. Repeat Layers: Repeat the layering process two more times, alternating potatoes, garlic, and cheese so that you have three layers total. This builds the rich, cheesy flavor throughout the dish.
  5. Season: Sprinkle salt, pepper, and fresh thyme evenly over the entire layered dish to infuse balanced seasoning.
  6. Add Cream: Pour the half and half or whipping cream evenly over the top layer, which will help create a creamy sauce as it bakes.
  7. Bake Covered: Cover the baking dish tightly with aluminum foil and bake for 30 minutes. This step allows the potatoes to start cooking through while retaining moisture.
  8. Bake Uncovered: Remove the foil and continue baking for an additional 20-30 minutes. Bake until the potatoes are tender when pierced with a fork, and the top layer is golden brown and bubbling.

Notes

  • For a round cast iron pan, butter the bottom generously to prevent sticking before layering ingredients.
  • Use a mandoline slicer for uniformly thin potato slices to ensure even cooking.
  • Let the scalloped potatoes rest for 10 minutes after baking to thicken before serving.
  • Gruyere cheese provides a nutty, melting quality; substituting with another good melting cheese like Emmental is possible but will alter the flavor.
  • This dish pairs wonderfully with roasted meats, steamed vegetables, or a crisp green salad.
