Prep Time: 20 mins
Cook Time: 50 mins
Total Time: 1 hrs 10 mins
Cuisine: American
Serves: 6 servings

Ingredients

  1. 4 large potatoes, thinly sliced
  2. 2 onions, thinly sliced
  3. 2 cups heavy cream
  4. 2 cups shredded cheese (cheddar or Gruyère)
  5. Salt and pepper to taste
  6. 2 tbsp butter

Instructions

  1. Preheat the oven to 375°F (190°C). Grease a 9x13 inch baking dish with butter to prevent sticking.
  2. In a large skillet, melt butter over medium-low heat. Add thinly sliced onions and cook slowly, stirring occasionally, until they become deep golden brown and caramelized, approximately 20-25 minutes. This process develops a rich, sweet flavor.
  3. Wash and thinly slice potatoes using a mandoline or sharp knife, aiming for consistent 1/8-inch thick slices. Immediately place sliced potatoes in cold water to prevent browning.
  4. Pat potato slices dry with clean kitchen towels to remove excess moisture, which ensures better layering and crispiness.
  5. In a large mixing bowl, combine heavy cream, salt, and black pepper. Whisk together to create a seasoned cream mixture.
  6. Begin layering in the prepared baking dish: Start with a thin layer of potatoes, followed by caramelized onions, then sprinkle shredded cheese. Repeat layers, ensuring even distribution.
  7. Pour the seasoned cream mixture evenly over the layered potatoes, allowing it to seep between layers.
  8. Cover the baking dish with aluminum foil and bake for 35 minutes to ensure potatoes cook thoroughly.
  9. Remove foil and continue baking for an additional 15 minutes until the top becomes golden brown and crispy, and potatoes are tender when pierced with a fork.
  10. Remove from oven and let rest for 10-15 minutes before serving. This allows the dish to set and makes serving easier.
  11. Garnish with fresh chopped parsley or chives if desired, and serve hot as a delicious side dish.

Tips

  1. Slice Consistently: Use a mandoline or sharp knife to ensure uniform potato slices. This guarantees even cooking and a beautiful presentation.
  2. Prevent Potato Browning: Immediately place sliced potatoes in cold water to stop oxidation, then thoroughly pat dry to ensure crispy layers.
  3. Caramelize Onions Slowly: Take your time with the onions—low and slow is the key to developing deep, sweet flavor. Don't rush this step!
  4. Layer Strategically: Create even layers of potatoes, onions, and cheese to distribute flavors throughout the dish.
  5. Cover and Uncover: Baking with foil initially helps cook the potatoes thoroughly, while the final uncovered baking creates a golden, crispy top.
  6. Let It Rest: Allowing the dish to sit for 10-15 minutes after baking helps it set and makes serving easier and more elegant.
  7. Optional Enhancement: Experiment with different cheese varieties like Gruyère for a more complex flavor profile.
