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
  • 0.5 tsp kosher salt
  • 0.5 tsp black pepper

Instructions

  1. Preheat and Prepare Dish: Preheat your oven to 400°F (200°C) and grease a ceramic baking dish to prevent sticking and ensure easy cleanup.
  2. Slice Potatoes: Peel and thinly slice the Yukon gold potatoes using a mandoline or a sharp knife for even, consistent slices that cook uniformly.
  3. Cook Garlic Butter Roux: In a large pot over medium heat, melt the butter. Add minced garlic and sauté for about 1 minute until fragrant but not browned.
  4. Add Flour: Stir in the all-purpose flour and cook for 1 to 2 minutes, stirring constantly to form a roux which will thicken the sauce.
  5. Incorporate Cream: Gradually whisk in the heavy cream, cooking for 5 minutes until the mixture thickens slightly, creating a smooth creamy base.
  6. Add Cheese and Seasonings: Stir in the grated Parmesan cheese, fresh thyme, kosher salt, and black pepper until the sauce is smooth and well combined.
  7. Toss Potatoes in Sauce: Add the thinly sliced potatoes to the sauce and gently toss to coat them evenly with the creamy mixture.
  8. Arrange Potatoes in Dish: Arrange potato slices upright in the prepared baking dish to allow even cooking and layering. Pour any remaining sauce over the top.
  9. Top with Parmesan: Sprinkle extra grated Parmesan cheese on top to develop a golden, crispy crust during baking.
  10. Bake Covered: Cover the dish with foil and bake for 30 minutes to allow the potatoes to cook through and the sauce to bubble.
  11. Bake Uncovered: Remove the foil and bake for an additional 30 minutes until the top is golden brown and bubbling beautifully.
  12. Rest and Serve: Let the scalloped potatoes cool for 10 minutes before serving. This resting time helps set the sauce and makes slicing easier.

Notes

  • For a lighter version, substitute heavy cream with whole milk or half & half.
  • Use a mandoline for uniformly thin potato slices which helps in even cooking.
  • Covering the dish during the first half of baking ensures tender potatoes, while uncovering creates a crispy top.
  • Letting the dish rest before serving allows the sauce to thicken and enhances flavor.
  • Fresh thyme can be substituted with dried thyme, but reduce the amount to ½ tsp.
