Instructions

  1. Step 1: Preheat oven to 375°F. Butter a 9x13-inch baking dish with 2 tbsp unsalted butter, spreading evenly over bottom and sides.
  2. Step 2: Arrange 2 lbs peeled and thinly sliced russet potatoes (about 1/8 inch thick) in a single layer in the baking dish. Season with 1/2 tsp salt and 1/4 tsp black pepper.
  3. Step 3: In a small saucepan, combine 1/2 cup heavy cream, 1/4 cup whole milk, 1/4 cup grated Gruyere cheese, and 2 tbsp chopped fresh thyme. Heat over medium heat, stirring constantly, until cheese melts and mixture is smooth and slightly thickened (about 5 minutes).
  4. Step 4: Pour cream mixture evenly over potatoes. Cover dish with aluminum foil and bake for 45 minutes. Remove foil and bake for 15-20 minutes longer until potatoes are tender and top is golden brown.
