Cook for 3.5 hours covered at 170°C. After that time use two forks to separate the chuck steak into smaller pieces. Return the baking dish back in the oven at 200°C for 30min uncovered this time to help reduce the sauce. Use two forks again to shred the beef now and then toss through the chopped parsley. Serve the shredded beef with some cooked pasta or leave them as they are in smaller pieces to serve with mash or rice etc.
