A comforting blend of thinly sliced potatoes layered with a velvety cheese sauce, perfect for busy weeknights.

Ingredients

Potato Layers

  • 5 pounds Russet or Yukon Gold Potatoes, peeled and thinly sliced (1/8-inch)

Cheese Sauce

  • 4 cups Heavy Cream
  • 1 cup Whole Milk
  • 10-12 ounces Gruyere Cheese, freshly grated
  • 4 ounces Sharp White Cheddar Cheese, freshly grated
  • 2 ounces Parmesan Cheese, freshly grated

Aromatics and Seasoning

  • 4-5 cloves Garlic, minced
  • 1 medium Yellow Onion, finely diced (optional)
  • 6 tablespoons Unsalted Butter, divided (Use 1 tbsp for greasing and 5 tbsp for cooking.)
  • 4 tablespoons All-Purpose Flour
  • 2 teaspoons Sea Salt, or to taste
  • 1 teaspoon Freshly Ground Black Pepper
  • ½ teaspoon Freshly Grated Nutmeg
  • 1 teaspoon Dried Thyme (or 2 teaspoons fresh, chopped)

Instructions 

Preparation

  • Preheat oven to 375°F (190°C). Grease a 9x13-inch baking dish with 1 tablespoon unsalted butter. Peel and thinly slice potatoes to 1/8-inch thickness, then pat dry. Grate all cheeses. Mince garlic and finely dice onion (if using).

Cooking

  • In a large saucepan, melt remaining 5 tbsp butter over medium heat. Sauté onion (if using) for 5-7 minutes until translucent. Add minced garlic and cook for 1-2 minutes until fragrant. Sprinkle in flour, stirring constantly for 1-2 minutes to form a roux.
  • Gradually whisk in heavy cream and whole milk until smooth and lump-free. Stir in sea salt, black pepper, freshly grated nutmeg, and dried thyme. Bring the sauce to a gentle simmer over medium-low heat, stirring frequently, until it thickens enough to lightly coat the back of a spoon (5-8 minutes). Remove from heat.
  • Add 1 cup grated Gruyere and ½ cup grated sharp white cheddar to the hot sauce, stirring until completely melted and smooth. Taste and adjust seasonings if needed.

Layering

  • Arrange about one-third of the dried, thinly sliced potatoes in an even layer at the bottom of the prepared baking dish. Ladle about one-third of the creamy cheese sauce evenly over the potatoes. Sprinkle with about one-third of the remaining Gruyere and sharp white cheddar cheese. Lightly season this layer with a small pinch of additional sea salt and freshly ground black pepper.
  • Repeat the potato, sauce, and cheese layering two more times, ensuring the last potato layer is neatly arranged. Pour any remaining sauce evenly over the final potato layer.
  • Generously sprinkle the remaining Gruyere, sharp white cheddar, and all of the grated Parmesan cheese over the entire surface of the gratin for the top crust.

Baking

  • Tightly cover the baking dish with aluminum foil. Place in the preheated 375°F (190°C) oven and bake for 60 minutes.
  • Carefully remove the foil. Return the uncovered dish to the oven and bake for another 30-45 minutes, or until the top is gloriously golden brown and bubbly, and the potatoes are fork-tender. Watch closely during the final minutes to achieve a perfect golden crust, using a broiler if needed for a quick finish.

Serving

  • Once baked, remove from the oven and let the gratin rest on a wire rack for at least 15-20 minutes before serving. This allows the sauce to set. Portion and serve, garnished with fresh parsley or chives if desired.

Notes

Customize with your favorite herbs or add cooked bacon for extra flavor. Store leftovers in an airtight container in the fridge for up to 3 days, or freeze for up to 3 months.
