Preheat the oven to 180 °C. Place the diced beef in a large mixing bowl with the spices and salt and pepper. Toss well to ensure the beef is evenly coated.
Heat half the oil in a large, heavy-based casserole dish over a medium heat. When the oil is hot, brown the beef in batches. Transfer the browned beef to a plate.
Cook the capsicums on a hotplate element until black and charred all over. Transfer to a bowl and cover with plastic wrap. After 15 minutes, peel off the skin and slice away the seeds and pith. Place the roasted capsicum in a food processor and blitz to a rough puree.
Add the rest of the oil to the casserole dish and lower the heat. Add the onions, garlic and chilli and saute gently for 2-3 minutes. Add the passata sauce, pureed peppers, stock and wine. Bring to the boil.
Return the beef to the casserole dish and transfer to the oven. Cook, covered, for 2 hours.
Serve with cooked gnocchi mixed though and fresh basil and coriander sprinkled over the top.
