Preheat your oven to 180°C (350°F).
Peel the potatoes and slice them thinly into rounds, around 2-3 mm thick. A mandoline slicer can help achieve consistent slices.
Peel and finely slice the onion into thin rings. Mince the garlic cloves.
Grease a baking dish with half of the butter to prevent sticking.
Layer half of the sliced potatoes evenly across the bottom of the baking dish. Sprinkle over half of the onion slices, minced garlic, salt, pepper, and thyme.
Repeat with the remaining potatoes and onions, finishing with a neat layer of potatoes on top.
Heat the vegetable or chicken stock in a saucepan or microwave until warm, then pour it gently over the layered potatoes and onions, ensuring the liquid just covers the top.
Dot the top layer with the remaining butter, distributing it evenly across the surface. Drizzle olive oil over the top if desired for added flavor and crispiness.
Cover the dish tightly with aluminum foil and bake in the preheated oven for 35 minutes.
After 35 minutes, remove the foil carefully and return the dish to the oven for another 20 minutes, or until the top is golden brown and the potatoes are tender when pierced with a knife.
Once cooked, remove from the oven and let the dish rest for 5 minutes before serving. Best served warm as a flavorful and light side dish.
