Ingredients

Scale

Main Ingredients

  • 2 lbs russet potatoes, peeled and thinly sliced
  • 2 large yellow onions, thinly sliced
  • 4 tablespoons unsalted butter
  • 1 cup heavy cream
  • 1 cup shredded Gruyère cheese
  • 1 cup shredded mozzarella cheese
  • 1 tablespoon fresh thyme, chopped
  • Salt and black pepper, to taste

Optional Additions and Substitutions

  • Cheese Variations: Swap Gruyère for cheddar, Swiss, or Fontina.
  • Cream Alternative: Use half-and-half or milk for a lighter version.

Instructions

Step1: Preheat and Prepare Ingredients

Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or non-stick spray.

Step2: Caramelize the Onions

  1. Melt 4 tablespoons butter in a large skillet over medium heat.
  2. Add sliced onions and a pinch of salt, stirring occasionally.
  3. Cook for 20-25 minutes, until the onions become golden brown and caramelized.
  4. Stir in fresh thyme, then remove from heat.

Step3: Layer the Ingredients

  1. Place half the sliced potatoes in the greased baking dish.
  2. Spread half of the caramelized onions over the potatoes.
  3. Pour half of the heavy cream evenly on top.
  4. Sprinkle half the Gruyère and mozzarella cheese.
  5. Repeat the layering process with the remaining potatoes, onions, cream, and cheese.

Step4: Bake the Dish

  1. Cover the dish tightly with foil and bake for 45 minutes.
  2. Remove the foil and bake for another 15-20 minutes, until the cheese is golden and bubbly.
  3. Let the dish rest for 10 minutes before serving.

Notes

  • Use a mandoline slicer – Ensures uniform potato slices for even cooking.
  • Slow-cook the onions – Caramelizing the onions properly enhances their natural sweetness.
  • Cover while baking – Prevents the top from burning while ensuring the potatoes are fully cooked.
  • Let it rest before serving – This helps the flavors meld together beautifully.
