Niedernauer kartoffeln is a traditional potato dish that's especially popular in Bavaria. The dish is usually made with a combination of potatoes, butter, eggs, cream or sour cream, onions, parsley, salt, and pepper. The potatoes are boiled and peeled while still hot.
Once cooled, they're cut into cubes, seasoned with salt and pepper, and fried in butter until golden brown with minced onions and parsley. A mixture of eggs and cream is poured over the potatoes and the dish is slowly cooked until the sauce is smooth and thick.
