Heat the oil in a pan and fry the minced meat until crumbly. Add sauerkraut, fold in, fry lightly and season with salt, pepper and paprika powder. Wash parsley, shake dry and chop.
Add the parsley to the mince and set the pan aside. Cut off the stalk of the bell pepper about 1 1/2 cm thick as a lid. Clean and wash the bell peppers. Fill the bell peppers with minced meat mixture. Put the stuffed peppers on a baking tray lined with baking paper, put the roasting set aside.
Place the lid on the peppers. Cook in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 30 minutes, if necessary cover the last minutes with aluminium foil. In the meantime, mix the roasting set with crème fraîche and milk.
Bring the sauce to the boil and season to taste with salt, pepper and paprika powder. Bind with sauce thickener. Take the peppers out of the oven, arrange them on a plate and pour on some sauce. Garnish with parsley. The rest of the sauce is extra.
Mashed potatoes taste good with it.
