With just 20 minutes of prep time, this oven-baked classic is your new go-to recipe for effortless indulgence.
Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with the olive oil to prevent sticking.
Peel the potatoes, then slice them thinly (about 1/8-inch thick) using a sharp knife or mandoline for even cooking.
Peel and finely dice the onion.
In a medium skillet, melt 2 tablespoons of butter over medium heat. Add the diced onion and sauté until soft and translucent, about 5 minutes. Set aside.
In a small saucepan, heat the heavy cream over low heat until warm but not boiling. Stir in the salt, pepper, and fresh thyme leaves.
Layer one-third of the sliced potatoes in the greased baking dish, slightly overlapping each slice. Sprinkle one-third of the sautéed onion and one-third of the grated Gruyère cheese over the potatoes.
Repeat the layering process two more times, finishing with a topping of Gruyère cheese.
Pour the warm cream mixture evenly over the layered potatoes, allowing it to seep through the layers.
Dot the top of the casserole with the remaining 2 tablespoons of butter, broken into small pieces.
Cover the dish loosely with aluminum foil and bake in the preheated oven for 40 minutes.
Remove the foil and continue baking for an additional 20 minutes, or until the top is golden brown and crispy, and the potatoes are tender when pierced with a knife.
Let the Chalet Potatoes rest for 10 minutes before serving to allow the flavors to meld. Serve warm and enjoy!
