A rich, slow-cooked beef stew infused with balsamic vinegar and dried porcini mushrooms for a deep, savory flavor. Served with a comforting swede and potato mash, this hearty meal is perfect for cold evenings and excellent for meal prepping.
Preheat your oven to 170°C (150°C fan/Gas 3). Heat the oil in a large, heavy-based ovenproof casserole dish. Add the sliced onions and fry for about 8 minutes, stirring occasionally, until they turn golden brown.
Increase the heat to high. Add the diced beef and chopped garlic to the casserole, stir-frying until the meat is browned on all sides.
Place the dried porcini mushrooms in a small bowl and pour 500ml of boiling water over them to hydrate. Pour the mushrooms and their soaking liquid into the casserole dish.
Stir in the balsamic vinegar, tomato purée, vegetable bouillon, and mustard powder. Add the chopped carrots, chestnut mushrooms, and thyme sprigs. Season with salt and black pepper to taste.
Cover the dish with a tight-fitting lid and place it in the oven. Bake for 3 hours until the beef is fork-tender. If the stew looks too dry toward the end of the cooking time, stir in a splash of water.
When the stew is nearly finished, prepare the mash. Boil the swede and potatoes together in a large pan of water for 12–15 minutes until soft. Drain well and mash thoroughly with a generous grating of black pepper.
Steam or boil the broccoli florets for about 5 minutes until tender. Serve the hot stew over the veggie mash with the broccoli on the side.
This stew tastes even better the next day! It can be stored in the fridge for up to 3 days or frozen for up to a month. When reheating, use a microwave for the stew and mash, and freshly steam the remaining broccoli to keep it vibrant and nutrient-rich.
