Step‑by‑Step Instructions for Crispy Grated Potato Pie with Spinach and Mushrooms
Step 1: Prepare the Potatoes
Begin by peeling and grating 600 grams of potatoes. Place the grated potatoes in a bowl of cold water and add a pinch of salt. Soak them for 15 minutes to remove excess starch. Once soaked, drain the potatoes in a colander and squeeze out the moisture using a clean kitchen towel—the drier, the crispier the crust!
Step 2: Sauté the Aromatics
In a skillet over medium heat, warm 2 tablespoons of olive oil. Add the chopped green onion, sautéing for 2-3 minutes until softened and fragrant. This step adds a wonderful base flavor, ensuring your filling in the Crispy Grated Potato Pie is aromatic and delicious. Remove from heat and set aside to cool slightly.
Step 3: Cook the Filling
To the same skillet, add the fresh baby spinach, seasoning it with salt and pepper. Cook for 2-3 minutes until the spinach wilts down beautifully. Next, incorporate 200 grams of sliced champignon mushrooms and minced garlic. Sauté everything for about 8 minutes until the mushrooms are golden and cooked through, then remove from the heat to cool further.
Step 4: Mix the Crust Ingredients
In a large mixing bowl, combine the drained grated potatoes with 80 grams of mozzarella cheese, 2 eggs, 2 tablespoons of fresh parsley, salt, pepper, and 1 teaspoon of dried oregano. This mixture forms the base of your Crispy Grated Potato Pie crust. Stir everything together until well incorporated, creating a lovely, cohesive filling.
Step 5: Form the Crust
Preheat your oven to 200°C (390°F). Brush a 9-inch round baking dish with the remaining 2 tablespoons of olive oil. Press the potato mixture firmly into the bottom and up the sides of the dish to form an even crust. Ensure it’s compact to achieve that perfect golden crispiness when baked, ready to hold the delicious filling.
Step 6: Bake the Crust
Place the crust in the preheated oven and bake for 35-40 minutes. You’ll want to keep an eye on it; it’s done when the edges are golden brown and crispy. This step is essential for a satisfying texture, setting a solid base for your savory filling in the Crispy Grated Potato Pie.
Step 7: Assemble the Pie
Once the crust is crispy and golden, take it out of the oven and spoon the cooled mushroom-spinach filling into the crust, spreading it evenly. Top with the remaining mozzarella and any additional cheese you’d like. This melted layer will create a beautifully gooey finish, enhancing the flavor profile of your pie.
Step 8: Final Bake
Return the assembled pie to the oven and bake for another 10-15 minutes. Watch closely for the cheese to melt and bubble. Once you see that gorgeous golden color, it’s time to take it out! The final bake creates a delicious contrast between the crunchy crust and the creamy filling.
Step 9: Cool and Garnish
Allow the Crispy Grated Potato Pie to cool for 5 minutes on a wire rack. This resting time will help the pie hold its shape when slicing. Before serving, sprinkle additional grated Parmesan and fresh parsley on top for a pop of flavor and color, elevating the dish’s presentation beautifully.
