Step‑by‑Step Instructions for Crispy Grated Potato Pie with Spinach and Mushrooms
Step 1: Grate and Soak the Potatoes
Begin by grating 600 g of starchy potatoes into a large bowl. To reduce starch and prevent a soggy crust, submerge the grated potatoes in cold water with a pinch of salt for 15 minutes. After soaking, drain and rinse them well, ensuring you whisk away any excess moisture.
Step 2: Sauté the Green Onions
Heat 2 tablespoons of olive oil in a skillet over medium heat. Add 1 chopped green onion and sauté until softened, about 3 minutes. The onions should be translucent and fragrant, setting the base for the filling of your Crispy Grated Potato Pie with Spinach and Mushrooms.
Step 3: Cook the Spinach
Next, add 150 g of baby spinach to the skillet with the softened onions. Season with a pinch of salt and pepper, cooking for 2-3 minutes until the spinach is wilted. Stir occasionally to ensure even cooking, focusing on the vibrant color change from bright green to tender.
Step 4: Add the Mushrooms
Incorporate 200 g of sliced champignon mushrooms into the skillet, along with 1 teaspoon of dried oregano, salt, and pepper to taste. Sauté for about 8 minutes, allowing the mushrooms to brown and their liquid to evaporate completely. The mixture should be golden and aromatic.
Step 5: Prepare the Potato Mixture
Drain the soaked potatoes thoroughly and squeeze out any remaining water; this is crucial for a crispy crust. In a large bowl, combine the potatoes with 80 g of shredded mozzarella, 2 large eggs, 2 tablespoons of chopped parsley, and the oregano you previously set aside. Mix until well combined.
Step 6: Preheat the Oven
Assemble your ingredients and preheat the oven to 200°C (390°F). While the oven heats, oil a 9-inch round baking dish generously to prevent sticking and facilitate easy removal of your delicious crispy pie.
Step 7: Form the Crust
Press the potato mixture firmly into the prepared baking dish, creating a crust that rises about 2 inches high. Ensure it’s evenly distributed and well-packed for a sturdy base. Bake in the preheated oven for 35-40 minutes, or until the crust is golden brown and crispy.
Step 8: Add the Filling and Cheese
Once the crust is baked, remove it from the oven and gently spoon the sautéed spinach and mushroom mixture into the center. Top it with 120 g of torn mozzarella fior di latte and 30 g of grated Parmesan cheese, ensuring an even distribution for that delightful melt.
Step 9: Final Bake
Return the filled pie to the oven and bake for an additional 10-15 minutes, until the cheese on top is bubbly and golden. The aromatic scent will fill your kitchen as it nears completion, promising a heartwarming dish awaited by all.
Step 10: Cool and Garnish
After baking, allow your Crispy Grated Potato Pie with Spinach and Mushrooms to cool for 5 minutes. This will help the filling set for easier slicing. Before serving, garnish with extra Parmesan cheese and fresh parsley for a touch of color and flavor!

Crispy Grated Potato Pie with Spinach and Mushrooms Recipe FAQs
What kind of potatoes should I use for the pie?
Absolutely! For the best results, I recommend using starchy potatoes like Russets or Yukon Golds. They provide the optimal texture and crispiness for the crust. Look for potatoes that are firm and smooth, avoiding any with dark spots or blemishes for a perfect pie.
How should I store leftover Crispy Grated Potato Pie?
Store any leftovers in an airtight container in the fridge for up to 3 days. If you want to maintain the crispiness, place parchment paper between the pie and the container lid. This helps avoid moisture buildup and keeps your pie tasting fresh!
Can I freeze the Crispy Grated Potato Pie, and how?
Yes, you can! Wrap the cooled pie tightly in plastic wrap, followed by foil, and store it in the freezer for up to 2 months. For reheating, thaw overnight in the fridge. When you’re ready to enjoy it, reheat in the oven at 180°C (350°F) for about 15-20 minutes to restore the lovely crispiness.
What should I do if my crust is soggy?
If you find that your crust is soggy, it might be due to excess moisture from the grated potatoes. To prevent this, make sure to thoroughly drain and squeeze out all water after soaking. Additionally, ensure that the mushrooms are cooked until golden and their moisture has evaporated before adding them to the filling. This will enhance the overall texture and prevent sogginess.
Can my pet eat any ingredients from this recipe?
It’s best to be cautious! While potatoes are safe for dogs in moderation, cheese should be given sparingly as some pets may be lactose intolerant. Spinach can be fed to pets in small amounts, but it’s always wise to double-check with your vet before introducing new foods into your pet’s diet!
