Ingredients
Scale
- 3 pounds Yukon Gold or Russet potatoes, peeled and thinly sliced
- 2 cups (200g) shredded Gruyere cheese
- 2 cups (480 ml) heavy cream
- 1 cup (240 ml) whole milk
- 3 tablespoons (about 45g) unsalted butter, melted
- 3 tablespoons (24g) all-purpose flour
- 2 cloves garlic, minced
- 2 teaspoons fresh thyme, finely chopped (or 1 teaspoon dried thyme)
- 1 teaspoon salt, plus more to taste
- ½ teaspoon freshly ground black pepper, plus extra for serving
- A pinch of nutmeg (optional)
Instructions
- Preheat oven to 350°F (175°C). Peel and thinly slice potatoes about 1/8 inch (3 mm) thick. Place slices in a large bowl.
- In a medium saucepan over medium heat, melt butter. Add minced garlic and cook for about 1 minute until fragrant but not browned.
- Whisk in flour and cook for 2 minutes to create a roux.
- Slowly whisk in heavy cream and milk, stirring constantly until sauce thickens, about 5 minutes. Season with salt, pepper, thyme, and nutmeg.
- Remove from heat and stir in 1½ cups (150g) Gruyere cheese until melted and smooth.
- Lightly butter a 9×13-inch baking dish. Layer half the potato slices evenly in the bottom. Pour half the cheese sauce over the potatoes.
- Repeat with remaining potatoes and cheese sauce. Sprinkle remaining ½ cup (50g) Gruyere evenly on top.
- Cover dish tightly with aluminum foil and bake for 45 minutes.
- Remove foil and bake uncovered for another 20-30 minutes until top is golden and bubbly and potatoes are tender.
- Let scalloped potatoes rest for 10 minutes before serving to thicken the sauce.
Notes
Use a mandoline for even potato slices to ensure uniform cooking. Cooking the flour with butter before adding cream prevents lumps. Covering the dish during baking traps steam and cooks potatoes evenly. Let the dish rest 10 minutes before serving to thicken the sauce. For gluten-free, substitute flour with cornstarch or gluten-free blend. For dairy-free, use coconut milk and vegan cheese.
