Ingredients

Scale
  • 2 pounds Yukon Gold potatoes, thinly sliced (about 900 g)
  • 6 tablespoons unsalted butter (85 g)
  • 2 cups heavy cream (480 ml)
  • 2 garlic cloves, minced
  • 1 ½ cups sharp white cheddar cheese, shredded (170 g)
  • ½ cup Gruyère cheese, shredded (55 g) – optional
  • 1 teaspoon fresh thyme leaves (or ½ teaspoon dried)
  • Salt, to taste
  • Freshly ground black pepper, to taste
  • 2 tablespoons all-purpose flour (15 g)

Instructions

  1. Preheat your oven to 350°F (175°C). Butter the baking dish generously.
  2. Wash and peel the Yukon Gold potatoes, then slice them thinly (about 1/8 inch or 3 mm). Place slices in a large bowl.
  3. In a medium saucepan over medium heat, melt the 6 tablespoons of unsalted butter. Cook, swirling occasionally, until it foams and turns golden-brown with a nutty aroma (about 4-5 minutes). Watch closely to avoid burning.
  4. Stir in minced garlic and thyme leaves into the brown butter, cooking for 1 minute until fragrant but not browned.
  5. Sprinkle the flour over the butter mixture and whisk continuously for about 1 minute to cook out the raw flour taste.
  6. Slowly pour in the heavy cream while whisking to avoid lumps. Continue cooking and stirring until the sauce thickens slightly, about 3-4 minutes. Season with salt and pepper to taste.
  7. Pour the warm cream sauce over the sliced potatoes in the bowl. Toss gently to coat all the slices evenly.
  8. Arrange half the potato slices evenly in the buttered baking dish. Sprinkle half the shredded cheddar and Gruyère cheeses over the layer. Repeat with the remaining potatoes and cheese.
  9. Place the dish in the preheated oven and bake uncovered for 50-60 minutes, or until potatoes are tender and the top is golden and bubbly.
  10. Let the scalloped potatoes rest for 10 minutes out of the oven before serving.

Notes

If the top browns too quickly before potatoes are tender, cover loosely with foil halfway through baking. For a crispier top, broil for the last 2-3 minutes but watch carefully to avoid burning. Use a mandoline for even slices or slice carefully by hand about 1/8 inch thick. Resting the dish before slicing helps it set and makes serving easier. For gluten-free, substitute flour with cornstarch or arrowroot powder. For dairy-free, use plant-based cream and vegan butter.
