Remove the skin from the onion and chop finely. Remove the peel from the garlic and crush it. Carrots rinse and remove the peel. Knead the mince well with 2 tbsp water, onion and garlic, and salt, pepper and a pinch of marjoram. Cut the beef into a large slab (it is best to have the butcher do this on the spot) and spread it out on a surface. Season with salt and pepper and spread the minced mixture on top. Top with carrots, roll up and tie with a kitchen spaghetti.
Rinse carrots, celery and parsley root, peel and cut into coarse pieces. Remove the skin from the onion and coarsely chop as well. Heat the oil in a frying pan and roast the roulade all around to a nice color. Remove from the frying pan and keep warm.
Roast the root vegetables and the onion in the residue of the roast, dust with flour and add a little soup. Add the kitchen herbs and put the meat repeatedly. Roast in the heated oven at 220 °C for about 90 minutes, frequently basting with soup, gravy and juices.
For the semolina dumplings: Mix semolina into the boiling milk and thicken. Brown breadcrumbs in butter and add to the cooled semolina form with 2 whole eggs, parsley and salt. Mix well and let it sit for a while. Form small dumplings and make them in salted water.
Remove the cooked beef from the frying pan.
