Casserole is always a great hearty meal for all the family, and always easy to make.
Brown the meat in 2-3 batches with the oil in a heavy-based pan. Transfer to a casserole dish. Gently fry the onions and garlic for 2-3 minutes in the same pan. Sprinkle over the flour and stir well until the onions and garlic are well coated.
Gradually pour in the stock and bring to the boil, stirring well, to make a smooth sauce. Season to taste. Add the diced vegetables and thyme and pour the sauce over the beef and vegetables.
Cover and cook in a pre-heated 160°C oven for 1½ to 2 hours or until very tender.
