How to Make White Cheddar And Parmesan Potato Gratin

  1. Preheat oven to 375°F (190°C).
  2. Butter a 13 x 9-inch glass baking dish.
  3. Sauté 1 medium onion, chopped, and 2 cloves garlic, minced, in 2 tablespoons butter or olive oil until softened (about 5-7 minutes). Set aside. (Can be prepared ahead of time)
  4. In a small bowl, whisk together 1 teaspoon dried rosemary and 1 cup heavy whipping cream.
  5. Layer half of the thinly sliced potatoes (about 2 pounds) in the prepared baking dish, slightly overlapping.
  6. Season with salt and pepper to taste. Sprinkle with 1 1/4 cups shredded white cheddar cheese, then the entire onion and garlic mixture, and 1/4 cup grated Parmesan cheese.
  7. Top with the remaining potatoes, salt, and pepper.
  8. Pour the cream mixture evenly over the potatoes. Sprinkle with the remaining 1/4 cup Parmesan cheese and the remaining 1 1/4 cups shredded white cheddar cheese.
  9. Loosely cover the baking dish with foil.
  10. Bake for 1 hour.
  11. Remove foil and bake for another 30-40 minutes, or until the potatoes are fork-tender and the top is golden brown.
  12. Let stand for 10 minutes before serving to allow the gratin to set slightly.
