Dice the onions and sauté in hot fat. Add tomato paste and roast briefly. Dust with paprika powder. Pour in a little meat stock and cook the onions until mushy. Mix in the meat (do not fry!), Add a little salt and cover in the hot oven for 1 1/2 - 2 hours at 180 °. The fact that the meat juice is not lost through frying, but rather passes into the sauce, results in a wonderful sauce even without being poured on! It goes well with bread dumplings or bacon dumplings!
