Step‑by‑Step Instructions for Grated Potato Pie with Spinach
Step 1: Prep Potatoes
Begin by peeling and grating 600 g of potatoes. Soak the grated potatoes in a bowl of cold water with a pinch of salt for about 15 minutes. This process removes excess starch and ensures a crispier crust. After soaking, drain and thoroughly squeeze out the water to prepare for mixing with the other ingredients.
Step 2: Sauté Filling
While your potatoes soak, heat 2 tablespoons of olive oil in a skillet over medium heat. Add one chopped green onion and sauté for 2-3 minutes until softened. Next, stir in 150 g of baby spinach, cooking just until wilted, about 1 minute. Finally, add 200 g of sliced champignon mushrooms, season with salt, pepper, and a teaspoon of dried oregano, and sauté until golden and any liquid evaporates. Set aside to cool.
Step 3: Mix Crust
In a large mixing bowl, combine the drained and squeezed potatoes with 80 g of mozzarella cheese, 2 large eggs, 2 tablespoons of chopped fresh parsley, salt, and pepper. Mix well until all ingredients are thoroughly incorporated. The potato mixture should feel cohesive and slightly sticky, allowing it to hold together when pressed into a crust.
Step 4: Form and Bake Crust
Preheat your oven to 200°C (390°F). Brush a baking dish with 2 tablespoons of olive oil to prevent sticking. Press the potato mixture evenly into the bottom and sides of the dish, creating a crust about 1/4 inch thick. Bake in the preheated oven for 35-40 minutes or until the crust is golden and crispy, watching for a deliciously inviting fragrance to fill your kitchen.
Step 5: Add Filling
Once the crust is baked, remove it from the oven and allow it to cool slightly. Spoon the sautéed mushroom and spinach filling into the crust, spreading it evenly. Next, sprinkle the remaining 100 g of mozzarella cheese, 120 g of mozzarella fior di latte, and 30 g of grated Parmesan over the top. This topping will melt beautifully and create a delightful layer of gooey cheese.
Step 6: Final Bake
Return the assembled Grated Potato Pie with Spinach to the oven and bake for an additional 10-15 minutes. Keep an eye on it until the cheese is melted and bubbly, with a lovely golden color. This final bake allows all the flavors to meld together, making each slice decadent and satisfying.
Step 7: Cool and Serve
After baking, allow the pie to cool for about 5 minutes to make slicing easier. For an extra touch, garnish the top with additional grated Parmesan and a sprinkle of fresh parsley. This crispy, flavorful dish can now be sliced and served warm, perfect for a cozy meal with family and friends.

Make Ahead Options
These Crispy Grated Potato Pie with Spinach and Mushrooms are perfect for meal prep! You can prepare the potato crust up to 24 hours in advance by following all the mixing and baking instructions, then cover it tightly and refrigerate.

To finish the recipe, simply spoon the filling into the pre-baked crust, top with cheese, and re-bake in the oven until the cheese is melted and bubbly. This way, you can enjoy a delicious, comforting meal with minimal effort, especially on busy weeknights!

-
Moisture Matters: Make sure to squeeze out as much moisture from the grated potatoes as possible. This step is crucial for achieving a crispy crust in your grated potato pie.

Crispy Grated Potato Pie with Spinach Recipe FAQs
What type of potatoes should I use for this recipe?
Absolutely! For the best results, use starchy potatoes like Russet or Idaho. These varieties provide structure and texture to the crust, ensuring it’s nice and crispy. Avoid waxy potatoes as they won’t yield the same results.
How should I store leftover potato pie?
Very simply! Store any leftover Grated Potato Pie in an airtight container in the refrigerator for up to 3 days. Make sure it’s well-covered to prevent drying out and maintain its delicious flavors!
Can I freeze the Grated Potato Pie?
Certainly! To freeze, wrap individual slices tightly in plastic wrap and then in aluminum foil. This method prevents freezer burn and allows you to enjoy them later. You can keep them frozen for up to 2 months. When you’re ready to eat, thaw overnight in the fridge and reheat in the oven for the best texture.
What can I do if my crust is soggy?
If you run into the issue of a soggy crust, it often means there was excess moisture in the potatoes. To prevent this in the future, ensure you soak the potatoes and squeeze out as much water as possible before mixing. A properly baked crust should be golden-brown and crispy—so keep an eye on it while it’s in the oven!
Is this pie suitable for people with gluten allergies?
