Ingredients
For the Potato Cakes:
2 lbs (about 900g) russet or Yukon Gold potatoes, peeled and quartered
1 large egg, lightly beaten
1/3 cup (40g) all-purpose flour, plus more for dusting
1/2 cup (50g) finely grated Parmesan cheese
2 green onions, finely sliced
1 tsp salt
1/2 tsp freshly ground black pepper
1/4 tsp garlic powder
2-3 tbsp neutral oil (like vegetable or avocado oil), for frying
For the Cheesy Spinach Filling:
1 cup (packed) fresh spinach, finely chopped
1 cup (115g) shredded mozzarella cheese
1/2 cup (115g) full-fat ricotta cheese
1/4 tsp ground nutmeg
Pinch of salt and pepper
For Serving (Optional):
Sour cream or Greek yogurt
Fresh chives or dill, chopped
Extra grated Parmesan
Warm marinara sauce for dipping
Instructions
1. Cook & Mash the Potatoes:
Place the peeled and quartered potatoes in a large pot of cold, salted water. Bring to a boil over high heat, then reduce to a simmer. Cook for 15-18 minutes, or until the potatoes are very tender when pierced with a fork. Drain thoroughly in a colander. Return the hot potatoes to the warm pot and let them steam-dry for a minute. Mash until completely smooth, without any lumps. Let cool for 5-10 minutes until just warm to the touch. This prevents the egg from cooking when added.
2. Prepare the Filling:
While the potatoes cool, mix the filling. In a medium bowl, combine the chopped spinach, shredded mozzarella, ricotta, nutmeg, salt, and pepper. Stir until well blended. Set aside.
3. Form the Potato Dough:
To the warm (not hot) mashed potatoes, add the beaten egg, flour, grated Parmesan, green onions, salt, pepper, and garlic powder. Use a spatula or clean hands to mix until a soft, pliable dough forms. It should hold together and not be sticky. If it feels too wet, add a tablespoon more flour.
4. Assemble the Stuffed Cakes:
Lightly dust your work surface and hands with flour. Divide the potato dough into 16 equal portions (roughly the size of a golf ball). Flatten one portion into a 3-inch disc in the palm of your hand. Place a heaping tablespoon of the cheese-spinach filling in the center. Flatten another potato portion into a disc and place it on top. Gently pinch and seal the edges together, then pat and shape into a neat, 1/2-inch thick patty. Repeat with the remaining dough and filling. Place the formed cakes on a floured plate or baking sheet.
5. Pan-Fry to Golden Perfection:
Heat 2 tablespoons of oil in a large non-stick or cast-iron skillet over medium heat. Once the oil shimmers, carefully add 4-5 potato cakes, leaving space between them. Do not overcrowd the pan. Fry for 4-5 minutes per side, or until deeply golden brown and crispy. Press down gently with a spatula to ensure even browning. Transfer to a paper towel-lined plate to drain. Add more oil to the skillet as needed and repeat with the remaining cakes.
6. Serve & Enjoy!
Serve the potato cakes immediately while hot and crispy. Garnish with a dollop of sour cream, a sprinkle of fresh herbs, and an extra crack of black pepper. They pair wonderfully with a simple arugula salad dressed with lemon vinaigrette.
Chef’s Notes & Tips for Success
Leftover Friendly: This is an excellent recipe for 2-3 cups of leftover mashed potatoes! Simply skip to step 3, ensuring your mash isn’t too loose.
Make-Ahead Magic: You can assemble the potato cakes up to a day ahead. Layer them between parchment paper on a baking sheet, cover, and refrigerate. Fry just before serving.
Baking Option: For a lighter version, preheat your oven to 400°F (200°C). Brush the cakes with oil and bake on a parchment-lined sheet for 20-25 minutes, flipping halfway, until golden.
Filling Variations: Get creative! Try fillings like cooked crumbled sausage, sautéed mushrooms, diced ham, or different cheese blends like cheddar and jalapeño.
Crisp is Key: Ensure your oil is properly hot before adding the cakes. A good sizzle means you’ll get that perfect, non-greasy crust.
