Peel the potatoes, wash them, and grate them using a coarse grater. Drain the liquid from the grated potatoes well and transfer them to a baking tray in an even layer. I used a 37 cm (15-inch) tray.

Sprinkle salt and ground black pepper to taste.

The second layer will be minced chicken, also sprinkled with salt and pepper.

Grate the hard cheese using a coarse grater. Transfer it to a bowl and add the sour cream and an egg.

Stir with a spoon.

Pour the mixture over the minced meat.

Cover the tray with aluminum foil and bake in a preheated oven at 180 degrees Celsius for about an hour.

10-15 minutes before it is ready, remove the aluminum foil and return to the oven to brown the surface.

Cut and serve. Enjoy!
