Wash the meat, dab dry and cut into approx. 6 equally sized pieces. Wrap a slice of bacon around each piece. Heat the oil in a large pan, fry the meat in it while turning it, season with salt and pepper, take it out and put it in a flat ovenproof dish.
Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for approx. 45 minutes.
Meanwhile melt 25 g butter, dust with flour and sweat. Deglaze with stock, 150 ml milk and cream. Boil up while stirring. Stir in mustard and cream cheese, bring to the boil again. Season to taste with salt, pepper, sugar and paprika.
After about 15 minutes of baking time, pour the sauce over the meat and finish baking.
Peel, wash and chop the potatoes. Peel and slice 2 cloves of garlic. Cook potatoes and garlic slices in boiling salted water for about 25 minutes. Heat 200 ml milk and 50 g butter.
Drain the potatoes, mash them coarsely with a potato masher, add the milk-butter mixture. Season to taste with nutmeg and salt.
Wash parsley, shake dry and chop finely, except for a few leaves for garnishing. Peel 1 clove of garlic and cut into fine slices. Heat 5 g butter and 1 tbsp. oil in a small saucepan, fry garlic slices crisp and golden brown while turning.
