3. Cook, stirring occasionally, for about 15-20 minutes until the onions are soft and golden brown.

4. Sprinkle half of the Gruyère and Parmesan cheese over the onions.
5. Repeat the layers with the remaining potatoes, onions, and cheese.

Step 4: Bake the Dish

1. In a bowl, whisk together 1 cup of heavy cream, ½ teaspoon salt, ¼ teaspoon black pepper, and 1 teaspoon fresh thyme leaves.
