Heat the oil and butter in a pan and briefly sear the seasoned steaks on both sides. Then you take them out of the pan immediately and let them rest on a plate. They shouldn`t be cooked through yet, just browned.
Lightly brown the finely chopped onions in the pan and then deglaze with a little cream. Reduce the heat and stir in the cream cheese and season to taste, e.g. with fresh herbs and nutmeg.
Let the sauce reduce a little and add the steaks to the pan. Simmer for a few more minutes over low heat.
I serve this with young boiled potatoes (unpeeled), quartered or eighth, depending on the size. In addition, broccoli florets cooked in cream and garlic.
