4 medium potatoes
2 cups thinly sliced onions
2 tablespoons butter
1 cup shredded Gruyère cheese
1.5 cups beef broth
1 teaspoon salt
0.5 teaspoon black pepper
1 teaspoon thyme
Directions
- Preheat the oven to 375°F (190°C). Grease a baking dish with butter to prevent the potatoes from sticking.
- Peel and slice the potatoes into thin rounds, ensuring even thickness for uniform cooking. Set aside.
- In a large skillet, melt butter over medium heat. Add the sliced onions and cook, stirring often, until they are caramelized, about 15 minutes.
- Arrange half of the potato slices in the prepared baking dish. Season with salt, pepper, and a sprinkle of thyme.
- Layer half of the caramelized onions over the potatoes. Pour half of the beef broth evenly over the top.
- Repeat the layers with the remaining potatoes and onions. Pour the remaining beef broth over the dish.
- Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes.
- Remove the foil, sprinkle the shredded Gruyère cheese over the top, and return to the oven.
- Bake uncovered for another 15-20 minutes until the cheese is melted and bubbly.
- Let the dish cool for a few minutes before serving to enhance the flavors and firm up the layers.
