French Onion Potatoes

1.

Preheat the oven to 375°F (190°C). Grease a baking dish with butter to prevent the potatoes from sticking.

2.

Peel and slice the potatoes into thin rounds, ensuring even thickness for uniform cooking. Set aside.

3.

In a large skillet, melt butter over medium heat. Add the sliced onions and cook, stirring often, until they are caramelized, about 15 minutes.

4.

Arrange half of the potato slices in the prepared baking dish. Season with salt, pepper, and a sprinkle of thyme.

5.

Layer half of the caramelized onions over the potatoes. Pour half of the beef broth evenly over the top.

6.

Repeat the layers with the remaining potatoes and onions. Pour the remaining beef broth over the dish.

7.

Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes.

8.

Remove the foil, sprinkle the shredded Gruyère cheese over the top, and return to the oven.

9.

Bake uncovered for another 15-20 minutes until the cheese is melted and bubbly.

10.

Let the dish cool for a few minutes before serving to enhance the flavors and firm up the layers.
