Ingredients

  • Russet potatoes
  • Yukon Golds (optional)
  • Gruyère cheese
  • Sharp White Cheddar cheese
  • Parmesan (or Parmigiano-Reggiano)
  • Heavy Cream
  • Garlic, finely minced
  • Shallot, finely minced
  • Unsalted Butter
  • All-purpose Flour
  • Salt
  • Freshly ground black pepper
  • Nutmeg
  • Cayenne pepper (optional)

Instructions

  1. Prepare the Potatoes: Peel the Russet potatoes and slice them as thinly and uniformly as possible, aiming for about 1/8-inch thickness. Transfer them to a large bowl of cold water and let them soak for about 15-20 minutes. Drain the potatoes thoroughly and pat them dry with kitchen towels.
  2. Make the Rich Cheese Sauce: In a medium saucepan, melt the unsalted butter over medium heat. Add the finely minced shallots and garlic, sautéing for 2-3 minutes until fragrant. Sprinkle in the all-purpose flour and whisk for about 1 minute to create a roux. Gradually pour in the heavy cream while whisking continuously to prevent lumps. Bring to a gentle simmer and cook for 3-5 minutes until thickened. Remove from heat and stir in about two-thirds of the grated Gruyère and white cheddar cheeses until melted. Season with salt, black pepper, and a pinch of nutmeg.
  3. Layer and Assemble: Preheat the oven to 375°F (190°C) and lightly butter a 9×13-inch baking dish. Spread a thin layer of cheese sauce on the bottom of the dish. Arrange a layer of potato slices over the sauce, followed by another layer of cheese sauce and a sprinkle of the remaining cheeses. Repeat the layering process until all potatoes are used, finishing with cheese sauce and remaining cheeses on top.
  4. Bake to Perfection: Cover the baking dish tightly with aluminum foil and bake for 45-50 minutes. Remove the foil and bake uncovered for another 20-30 minutes until the top is golden brown and bubbly.
  5. Rest and Serve: Let the dish rest for at least 15-20 minutes before serving to allow the sauce to set.
