Ingredients:

• 3 tablespoons butter
• 3 onions, thinly sliced
• 2.6 lb washed potatoes (about 6 medium-sized potatoes), thinly sliced
• 2 tablespoons fresh rosemary, finely chopped
• 2 teaspoons salt
• 1 teaspoon black pepper
• 2 cups vegetable broth or stock

Instructions:

1. Preheat the Oven:
   • Preheat your oven to 350°F (175°C).
   • Grease a medium-sized baking dish with a bit of the butter to prevent sticking.
2. Prepare the Onions and Potatoes:
   • Melt 2 tablespoons of butter in a skillet over medium heat.
   • Add the thinly sliced onions and cook for 8-10 minutes, stirring occasionally, until they are softened and slightly golden.
   • Remove from heat.
   • 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.
