How to Make Crispy Potato Pie
-
Prepare Potatoes: Begin by grating the potatoes and soaking them in cold, salted water for 15 minutes. This helps remove excess starch and ensures a nice crispy texture.
-
Sauté Vegetables: In a skillet, heat olive oil over medium heat. Add the chopped green onion and sauté until soft, about 2-3 minutes. Next, throw in the spinach, seasoning it lightly, and cook until wilted. Finally, add the sliced mushrooms, garlic, and seasoning, cooking until the mushrooms are golden and any liquid has evaporated. Set the mixture aside to cool.
-
Make Potato Dough: Drain the soaked potatoes thoroughly, then squeeze them dry with a clean kitchen towel. In a large bowl, combine the potatoes with mozzarella, eggs, parsley, salt, pepper, and oregano, mixing well until combined.
-
Form the Crust: Preheat your oven to 200°C (390°F). Grease a round baking dish with a little olive oil. Press the potato mixture into the dish, forming a crust that stands about 2 inches high around the sides.
-
Bake Crust: Place the crust in the preheated oven and bake for 35-40 minutes, or until the edges are golden brown and crispy.
-
Assemble Pie: Once the crust is baked, remove it from the oven. Spoon the cooled mushroom and spinach mixture into the crust, spreading it evenly. Top with the remaining mozzarella and freshly grated Parmesan cheese.
-
Final Bake: Return the pie to the oven and bake for an additional 10-15 minutes, until the cheese is melted and bubbly. Allow it to cool for about 5 minutes before slicing into it, garnished with extra Parmesan and parsley if desired.
Optional: Drizzle with a bit of olive oil before serving for added flavor.
