Then strain them. Preheat the oven to 150 °C. (top/bottom heat).
Roughly dice the meat and add to the strained onions together with the tomato paste, garlic, vinegar and all spices. Mix everything well.
Cover the pot with a heat-resistant lid and put it in the preheated oven. Cover and cook the goulash in the oven at 150 °C for 2.5 – 3 hours.
Season the goulash to taste before serving.
