Potato cutlets (Zrazy) are made from mashed potatoes with different stuffing, usually these are meat, mushrooms, cabbage or cheese. In this recipe I use mushroom. For juiciness and aroma, mushrooms are fried on a frying pan together with onions. Potato is well combined with mushrooms, so the dish has harmonious taste. Potato cutlets (Zrazy) is served as a separate dish without any side dishes, it is only enough to use as a sauce sour cream which goes perfectly with zrazy and they become even tastier.
