Shepherd's pie with hard cheese

Boil the potatoes after peeling them until cooked. Drain the water and mash with a fork. Add salt, one whole egg, and one yolk, and mix thoroughly.

Chop the onion, garlic, and meat into small cubes, fry in vegetable oil until half-cooked, and add salt.

Place half of the mashed potatoes at the bottom of the baking dish, then add the fried thigh and cover with the remaining layer of potatoes.

Spread a thin layer of sour cream, sprinkle with finely grated parmesan, and send to an oven preheated to 180 degrees for ten to twelve minutes.
