Instructions

  1. Step 1: Preheat oven to 375°F (190°C). Thinly slice potatoes (1/8 inch thick) using a mandoline or sharp knife, then soak in cold water for 10 minutes to remove excess starch. Drain and pat dry with paper towels.
  2. Step 2: Melt butter in a medium saucepan over medium heat. Add minced garlic and cook for 1 minute until fragrant. Whisk in heavy cream, salt, and pepper, then bring to a gentle simmer. Cook for 5 minutes until slightly thickened, stirring frequently.
  3. Step 3: Remove sauce from heat and stir in 3/4 cup grated Gruyère cheese until melted and smooth. Stir in chopped chives and thyme. Taste and adjust seasoning.
  4. Step 4: Spread half the potato slices evenly in a greased 9x13-inch baking dish. Pour half the cheese sauce over potatoes, then layer remaining potatoes and sauce. Sprinkle remaining 1/4 cup Gruyère on top. Bake uncovered for 45-50 minutes until potatoes are tender and sauce is bubbly around the edges.
