Quickly fry the minced beef to seal.
Transfer to a casserole and add the onion, carrots and red wine (if used).
Add water to cover.
Season to taste.
Cover with a lid of foil and fit the casserole lid on top, forming a good seal.
Cook in the oven at 180°C for 1 hour and a quarter.
Remove from oven, check seasoning and stir in a good handful of Quaker Oats. Allow to stand for at least five minutes before serving with mashed potato or a good chunk of bread.
