For the Karreesteak with herb sauce, cut the onion into small cubes. Heat the oil in a pan, sear the steaks on both sides, then fry for another 2 – 3 minutes over low heat and keep warm.
Sauté the onion pieces in the roast residue, pour in the soup and stir in the whipped cream. Simmer for a few minutes and stir in the herbs. Season to taste with salt and pepper.
Add the steaks to the sauce and serve.
