01 -
900 g Yukon Gold or Russet potatoes, thinly sliced
02 -
2 tablespoons olive oil or unsalted butter
03 -
2 large yellow onions, thinly sliced
04 -
1 teaspoon granulated sugar
05 -
0.5 teaspoon fine sea salt
06 -
0.25 teaspoon freshly ground black pepper
07 -
1 teaspoon fresh thyme leaves or 0.5 teaspoon dried thyme
08 -
2 cloves garlic, finely minced
09 -
240 ml low-sodium beef or vegetable broth
10 -
1 tablespoon Worcestershire sauce
11 -
150 g shredded Swiss or Gruyère cheese
12 -
25 g grated Parmesan cheese
13 -
1 tablespoon fresh parsley, chopped (for garnish)
# Step-by-Step Instructions:
01 -
Heat olive oil or butter in a large skillet over medium-low heat. Add sliced onions and sugar, then cook for 20 to 25 minutes, stirring often, until onions are golden and soft. Stir in garlic and thyme, cooking for 1 additional minute. Set onions aside and preheat oven to 190°C.
02 -
Wash and peel potatoes. Use a sharp knife or mandoline to cut potatoes into 3 mm (1/8 inch) thin slices, ensuring uniform thickness for even cooking.
03 -
Grease a 33 x 23 cm baking dish. Layer half of the sliced potatoes evenly in the dish, then cover with half of the caramelized onions and a portion of Swiss or Gruyère cheese. Repeat layering with remaining potatoes, onions, and more cheese.
04 -
In a small bowl, mix broth with Worcestershire sauce. Pour the mixture evenly over the layered potatoes. Top with remaining Swiss or Gruyère cheese and sprinkle with grated Parmesan.
05 -
Cover the baking dish tightly with foil and bake in the preheated oven for 40 minutes. Potatoes will steam and soften during this stage.
06 -
Remove foil and continue baking for an additional 15 to 20 minutes, or until the cheese is golden and bubbly and potatoes are fully tender.
07 -
Let the dish rest at room temperature for 10 minutes before serving. Garnish with freshly chopped parsley to finish.
