The fried potatoes (fried potatoes) can be cooked from raw potatoes as well as with boiled potatoes.
The boiled potatoes can thereby be cut into slightly thicker slices.

Preparation with raw potatoes (classic) :
For the Brägele/Bratkartoffeln (= fried potatoes) wash, peel and cut waxy potatoes into thin slices. Peel and finely dice an onion.

Heat little olive oil with some butter in a heavy skillet (preferably cast iron), add the potato slices and fry until golden brown for about 15-20 minutes, turning frequently.

Just before the potatoes are cooked, add salt , diced onion and sauté (not too hot, otherwise the onions will become black and bitter.)

If you like you can also add some diced bacon.

Sprinkle to taste with fresh, chopped herbs , such as parsley or chives.
