Finely dice the onion, wash and clean the paprika and roughly cut into strips. Sauté both in a little fat and simmer covered for about 15 minutes over low heat, until the pepper pieces are soft.
Meanwhile, clean the mushrooms, quarter them and fry them over high heat with little fat until they are cooked, season with salt and pepper and add a little liquid if necessary.
For the sauce, puree the pepper and onion mixture and then stir in the cream, season with salt and pepper. Add the sauce to the mushrooms and serve with rice or spaetzle, for example.
