Peel and grate the potatoes. Drain the liquid. Mix the potatoes with eggs, grated onion, salt, parsley, and pepper.
Heat the oil in a skillet and then put the dough in, 3 tablespoons at a time. Spread the dough out evenly. Bake on both sides until golden brown.
Potato pancakes can be served with any meat. A different way to serve them is with applesauce (the most common way they are eaten in Germany).
