Method
Preparation
- Preheat your oven to 375°F (190°C).
- In a large skillet, heat the olive oil and butter over medium heat. Add the sliced onions. Cook for about 15-20 minutes, stirring occasionally, until they turn golden and caramelized.
- Once the onions are caramelized, add the beef or vegetable broth and thyme, making sure to scrape up any delicious bits stuck to the pan. Season with salt and pepper.
- In a greased baking dish, start layering half of the sliced potatoes. Pour half of the onion mixture over them, then add a layer of cheese. Repeat with the remaining potatoes, onion mixture, and finish with a generous layer of cheese on top.
Cooking
- Cover the baking dish with aluminum foil and bake for 30 minutes.
- Remove the foil and bake again for another 15-20 minutes, until the cheese is bubbly and golden.
- Remove from the oven, and sprinkle with fresh parsley before serving. Enjoy!
