# Instructions:
01 -
Heat butter and olive oil in a large skillet over medium-low heat. Add sliced onions, salt, black pepper, sugar, garlic powder, and thyme. Cook slowly, stirring occasionally, for 20 to 25 minutes until onions turn deep golden brown. Pour in broth, stir, and cook for 5 more minutes until onions are soft and jammy. Remove from heat and set aside.
02 -
Preheat oven to 190°C. Grease a 23×33 cm baking dish with butter. Slice Yukon Gold potatoes into 0.6 cm rounds. Combine potato slices with heavy cream, salt, black pepper, and fresh thyme in a large bowl.
03 -
Arrange half of the potato slices evenly in the prepared baking dish. Distribute half of the caramelized onions on top. Sprinkle with half of the Gruyère cheese and half of the Parmesan. Layer the remaining potatoes, onions, and cheeses. Pour any remaining cream over the top.
04 -
Cover dish tightly with aluminium foil and bake for 40 minutes. Remove foil and continue baking for another 20 minutes, until cheese is golden and bubbling. For extra crispness, broil for 2 to 3 minutes at the end.
05 -
Let the bake rest for 5 minutes after removing from oven. Garnish with fresh thyme sprigs, extra Parmesan cheese, and crispy fried onions if desired. Serve warm.
# Notes:
01 -
Slice potatoes evenly for consistent baking and texture.
02 -
Caramelizing onions slowly results in deeper, sweeter flavor.
03 -
For a vegetarian dish, substitute beef broth with vegetable broth and check the cheeses.
