Ingredients

Scale

Potatoes

  • 5 pounds Yukon gold potatoes, thinly sliced

Sauce

  • 2 tbsp unsalted butter
  • 2 cloves garlic, minced
  • 1 tbsp all-purpose flour
  • 1 cup heavy cream (or whole milk/half & half)
  • 0.5 cup Parmesan cheese, grated (plus extra for topping)
  • 1 tsp fresh thyme

Seasoning

  • 0.5 tsp kosher salt
  • 0.5 tsp black pepper

Instructions

  1. Preheat Oven: Preheat your oven to 400°F (200°C) and grease a ceramic baking dish to prevent sticking and allow easy cleanup.
  2. Prepare Potatoes: Peel the Yukon gold potatoes and thinly slice them using a mandoline or a sharp knife for even cooking and a delicate texture.
  3. Make Garlic Butter: In a large pot, melt the butter over medium heat. Add the minced garlic and cook for 1 minute until fragrant, infusing the butter with garlic flavor.
  4. Create Roux: Stir in the all-purpose flour and cook for 1–2 minutes, which will help thicken your sauce later.
  5. Add Cream: Gradually whisk in the heavy cream and continue cooking the mixture for about 5 minutes until it slightly thickens, forming a creamy base.
  6. Incorporate Cheese and Herbs: Stir in the grated Parmesan cheese, fresh thyme, kosher salt, and black pepper, blending until smooth and flavorful.
  7. Coat Potatoes: Add the thinly sliced potatoes to the sauce and gently toss to coat them evenly in the creamy mixture.
  8. Arrange Potatoes: Place the potato slices upright in the greased baking dish, then pour any remaining sauce over the top to ensure full coverage.
  9. Add Topping: Sprinkle extra grated Parmesan cheese on top to create a delicious golden crust while baking.
  10. Bake Covered: Cover the dish with foil to retain moisture and bake for 30 minutes at 400°F (200°C).
  11. Bake Uncovered: Remove the foil and bake for an additional 30 minutes until the top is golden brown and bubbling.
  12. Cool and Serve: Let the scalloped potatoes cool for 10 minutes before serving to allow the sauce to set slightly for perfect slices.

Notes

  • Using Yukon gold potatoes adds a creamy texture and buttery flavor.
  • Thin slicing ensures the potatoes cook evenly and absorb the sauce well.
  • You can substitute heavy cream with whole milk or half & half for a lighter sauce.
  • Adding fresh thyme imparts a subtle herbaceous note complementing the creamy cheese sauce.
  • Covering with foil during the first half of baking prevents the dish from drying out.
  • Letting the dish rest before serving helps the scalloped potatoes hold together when sliced.
  • Use a mandoline carefully to avoid injury when slicing potatoes thinly.
