Stuffed Potato Patties with Mushroom Filling

I’ve perfected these golden-crusted potato patties filled with savory mushrooms and melty cheese to create the ultimate comfort food experience. This recipe transforms simple ingredients into an irresistible dish that combines crispy exteriors with creamy, flavorful centers. What makes these patties special is the surprising burst of mushroom filling and cheese that awaits inside each golden-brown exterior.

A Touch of History

These stuffed potato patties draw inspiration from Eastern European cuisine, particularly the Russian “Zrazy” and Ukrainian “Kartoplianyky.” Traditionally, these dishes were created as a way to transform leftover mashed potatoes into something extraordinary. I’ve enhanced this classic concept by incorporating a rich mushroom filling and adding mozzarella for an indulgent modern twist.

Detailed Instructions

Preparing the Perfect Mashed Potatoes

1. Peel potatoes and cut into uniform chunks.
2. Place in cold, salted water and bring to a boil.
3. Cook until tender when pierced with a fork (about 15-20 minutes).
4. Drain thoroughly and return to pot over low heat for 1-2 minutes to remove excess moisture.
5. Mash while hot until completely smooth.
6. Add 2 beaten eggs, 2 tablespoons flour, salt, and pepper.
7. Mix until well combined but don’t overmix.
8. Allow to cool until comfortable to handle.

Creating the Flavorful Filling

1. Finely chop mushrooms using a sharp knife or food processor.
2. Melt butter in a large skillet over medium heat.
3. Add diced onion and cook until soft and translucent (5-6 minutes).
4. Add grated carrot and cook for 2-3 minutes until softened.
5. Add chopped mushrooms and increase heat to medium-high.
6. Cook, stirring frequently, until all moisture evaporates (8-10 minutes).
7. Season generously with salt and pepper.
8. Transfer to a bowl and let cool completely.

Assembly Process

1. Place 1 cup flour on a shallow plate.
2. Take about 3 tablespoons of potato mixture and flatten in your palm.
3. Create a small well in the center.
4. Place 1 tablespoon mushroom filling and a cube of mozzarella in the well.
5. Carefully fold edges over to enclose filling completely.
6. Shape into an oval patty about 3 inches long.
7. Coat thoroughly in flour, shaking off excess.
8. Repeat with remaining mixture.

Cooking to Golden Perfection

1. Heat 2 tablespoons butter in a large skillet over medium heat.
2. Dip flour-coated patties in beaten egg.
3. Place in hot pan, being careful not to overcrowd.
4. Fry for 3-4 minutes per side until golden brown and crispy.
5. Transfer to paper towels to drain excess butter.
6. Keep warm in a 200°F oven while cooking remaining batches.

Preparing the Sauce

1. In a small bowl, combine yogurt and chopped dill.
2. Season with salt to taste.
3. Refrigerate until ready to serve.

Expert Tips

• Use starchy potatoes for the best texture.
• Make sure mashed potatoes are completely smooth for easier shaping.
• Let both potatoes and filling cool before assembly to prevent breakage.
• If mixture becomes too soft, chill in refrigerator for 30 minutes.
• Test oil temperature with a small piece of mixture – it should sizzle gently.
• Don’t flip patties too early; wait for a golden crust to form.
