Instructions

  1. Step 1: Preheat oven to 375°F (190°C). Thinly slice 2 lbs Yukon Gold potatoes into 1/8-inch rounds using a mandoline or sharp knife.
  2. Step 2: Melt 3 tbsp butter in a large oven-safe skillet over medium heat. Add 2 minced garlic cloves and cook for 1 minute until fragrant but not browned.
  3. Step 3: Whisk in 2 tbsp all-purpose flour to form a roux, cooking for 1 minute. Gradually whisk in 1 cup heavy cream until smooth, then simmer for 3 minutes until slightly thickened.
  4. Step 4: Stir in 1 tsp salt, 1/2 tsp black pepper, and 1 tbsp fresh thyme. Remove from heat and stir in 1 cup shredded gruyère cheese until melted.
  5. Step 5: Arrange half the potato slices in the skillet, pour half the sauce over them, then layer with the remaining potatoes and sauce. Top with any remaining cheese.
