Instructions

  1. Step 1: Preheat oven to 375°F (190°C). Thinly slice 2 medium russet potatoes into 1/8-inch rounds, then arrange in a single layer in a greased 9x13-inch baking dish.
  2. Step 2: In a small bowl, mix 1/2 cup heavy cream, 1/4 cup diced onion, 1 tbsp fresh thyme leaves, 1/2 tsp salt, and 1/4 tsp black pepper, then pour evenly over the potatoes.
  3. Step 3: Sprinkle 1 cup shredded cheddar cheese over the top, pressing gently to adhere, then cover with foil and bake for 45 minutes until potatoes are tender when pierced with a fork.
  4. Step 4: Remove foil and bake uncovered for 10 more minutes until the cheese is golden and bubbly, then let rest for 5 minutes before serving.
