Preheat the Oven
Preheat your oven to 375°F (190°C). This ensures your Torta di Patate cooks evenly.
Boil the Potatoes
Peel and chop the potatoes into quarters. Place them in a large pot and cover with cold water. Add a pinch of salt. Bring to a boil and cook for about 15-20 minutes or until the potatoes are fork-tender.
Prepare the Mixture
Once the potatoes are cooked, drain them and let them cool slightly. In a mixing bowl, mash the potatoes until smooth. Add the eggs, milk, Parmesan cheese, olive oil, salt, pepper, and any fresh herbs. Mix well until combined.
Add Optional Ingredients
If using, stir in the chopped onion and any additional fillings like spinach or sausage. This adds extra flavor and makes the dish heartier.
Transfer to Baking Dish
Grease your baking dish with a bit of olive oil or butter. Pour the potato mixture into the dish, spreading it evenly.
Bake
Bake in the preheated oven for 30-35 minutes until the top is golden brown and the edges are crispy.
Let It Stand
Once baked, let the Torta di Patate stand for about 10 minutes before slicing. This helps it hold its shape when served.
Serve and Enjoy
Cut into squares or wedges and serve warm. Enjoy your Torta di Patate as a main dish or a side!
