How to Make Potatoes Gratin

  1. Preheat oven to 350°F (175°C).
  2. Grease a 9x13 inch casserole dish with 2 tablespoons of unsalted butter.
  3. Thinly slice 2 pounds of Yukon Gold potatoes. Soak sliced potatoes in cold water for 15 minutes to remove excess starch.
  4. Finely chop 1 medium yellow onion.
  5. Layer half of the potatoes in the prepared casserole dish, slightly overlapping.
  6. Sprinkle with 1/4 teaspoon salt, 1/4 teaspoon black pepper, and 1/2 cup shredded sharp cheddar cheese.
  7. Pour 1/2 cup heavy cream over the potato layer.
  8. Repeat layers with remaining potatoes, onions, salt, pepper, cheese, and cream.
  9. Top with the remaining 1/2 cup shredded cheddar cheese and a tablespoon of cream.
  10. Bake uncovered for 45-50 minutes, or until the gratin is bubbly and the top is golden brown and the potatoes are tender.
  11. Optional: During the last 5 minutes of baking, top with 1/2 cup crumbled Ritz crackers or seasoned bread crumbs for extra crunch.
