Step-by-step instructions
-
Caramelize the Onions: Start by melting 2 tablespoons of butter and 1 tablespoon of olive oil in a large pan over medium heat. Add the sliced onions, salt, and sugar (if using). Cook them slowly, stirring occasionally, until they caramelize and become golden brown—this should take around 20-25 minutes.
-
Prepare the Potatoes: While the onions are caramelizing, slice your Yukon Gold potatoes into ¼-inch thick rounds. Rinse them under cold water to remove excess starch, then pat them dry.
-
Assemble the Bake: Preheat your oven to 375°F (190°C) and grease a baking dish with 1 tablespoon of butter. In a large bowl, mix the heavy cream (or milk), additional salt, pepper, and fresh thyme. Layer half of the potato slices in the dish, add half of the caramelized onions on top, and sprinkle with Gruyère and Parmesan cheese. Repeat with the remaining potatoes, onions, and top it all with the cream mixture.
-
Bake the Dish: Cover the dish with aluminum foil and bake for about 30 minutes. Remove the foil and continue baking for an additional 15-20 minutes, or until the top is golden brown and bubbling.
-
Serve & Enjoy!: Allow the dish to cool slightly before serving. Garnish with fresh thyme sprigs and crispy fried onions for a delightful crunch!
