Instructions:

  1. Preheat the Oven:

    • Add the thinly sliced onions and cook for 8-10 minutes, stirring occasionally, until they are softened and slightly golden.

    • While the onions are cooking, wash and thinly slice the potatoes (about 1/8 inch thick) using a sharp knife or mandoline for even slices.
  3. Layer the Potatoes and Onions:
    • In the greased baking dish, layer half of the sliced potatoes evenly across the bottom.
    • Season with 1 teaspoon of salt and ½ teaspoon of black pepper.
    • Spread half of the sautéed onions over the potatoes, followed by half of the chopped rosemary.
    • Repeat the layers with the remaining potatoes, salt, pepper, onions, and rosemary.
  4. Add the Broth:
    • Pour the vegetable broth or stock evenly over the layered potatoes and onions.
    • Dot the top of the dish with the remaining 1 tablespoon of butter.
  5. Bake:
    • Cover the dish with aluminum foil and bake in the preheated oven for 45 minutes.
    • After 45 minutes, remove the foil and bake for an additional 25-30 minutes, or until the top is golden and crispy and the potatoes are tender when pierced with a fork.
  6. Serve:
    • Let the dish rest for a few minutes before serving.
    • Serve as a side dish with roast meats, chicken, or on its own for a hearty vegetarian option.
