Peel and finely dice the onion and garlic. Heat 2 tablespoons of oil and butter in a saucepan, fry the onion and garlic at low heat until transparent. Add rice and sauté briefly. Season with pepper.
Gradually add stock, stirring from time to time. Always add the next portion of liquid only after the rice has absorbed the liquid. Cook for a total of 30-35 minutes.
Add the vegetables about 8 minutes before the end of the cooking time and cook. In the meantime dab meat dry. Heat 2 tablespoons of oil in a frying pan and fry the meat thoroughly all around. Mix the balsamic cream and 1 tbsp. oil.
Season with salt and pepper. Place the meat on a baking tray and brush with balsamic cream. Put the rest of the cream aside.
Bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for 12-15 minutes. In the meantime, peel off some shavings of Parmesan cheese with a peeler. Grate the remaining cheese finely to cream, stir into the risotto, heat up briefly, season with salt and pepper.
Remove meat from the oven, let it rest for a short time, cut into thin slices and sprinkle with remaining cream. Arrange risotto and meat on plates sprinkled with Parmesan shavings.
